Swedish translation from English, 25.11.2010. that it will be difficult to guarantee a commercially useful product. The use of MPEG4 provides a very high quality of video streams, but places higher demands on stability It is also expensive and extensive to develop their own proprietary communication protocols to reduce the effects of such errors. These often receive limited distribution and above all this means that customer equipment will be expensive.
    The existence of a technology is due to low unit prices. This practice can only be achieved for recognized standards that ensure high production volumes For standardized systems cabemodem standards such as DOCSIS and DVBx, the prevalence is high, QoS Quality of Service is well established and supported globally. Extensive distribution of such technology ensures low unit prices for cost-critical units.
    In addition, wireless standards such as 802.11x and the like are very sensitive to variations in link quality for critical service transmission. Even with the forthcoming editions of these standards, the most demanding service fates will require a stable link with limited deviations in bandwidth, low BER and low jitter.
    Other open standards intended for alternative infrastructures when there is high dispersion, dynamic noise conditions and varying loss conditions cannot in practice achieve sufficient Quality of Service for critical services. Eicempelpåiijsådfana, open. standards are HomelPlug. Similar considerations also apply to similar, proprietary standards. In particular, bandwidth dynamics are the problem, but also time-varying delays.
    Similar considerations apply to open and proprietary standards for medium and narrow bandwidth. There are similar problems for wireless standards such as Zigbee and PLC. For ZigBee »and similar standards, marginal links will require the system to spend a lot of resources to set: if the oggöfrbtlll disrupt or destroy real-time performance. For PLC, 20 Date means: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. also the use of the most interference intensive part of the frequency spectrum for communication that interference in this frequency range is quite unpredictable. A typical example is that noise or disturbance from a fault that is about to occur on a power line becomes so strong that it puts a PLC system to report and characterize the fault, out of operation. Low-frequency PLCs suitable for two-way communication must be used according to high excitation effects as impractical or unrealistic, especially in sensor, monitoring sites.
    When the described problems will be attacked with solutions described in PCT / NO2006 / 000137, the industrial part of assembly on a dangerous infrastructure is a very critical factor. This applies regardless of whether we are talking about low frequency, shortwave frequency, VHF and UHF or microwave.
    There is therefore a need for a technical solution that has made it possible to easily: combine solutions PCTNO2006 / 00137l with standard equipment such as DOCSlS and Dvimian au bit arrar rara BER förvarrarijtiähsiariiåšfkšiaiiiiai in critical degrees in the case of critical applications. There is also a need for such solutions to be improved with respect to industrial development in competition with more expensive, alternative technical solutions. There is therefore a need for new solutions that ensure that assembly challenges do not destroy the competitiveness of these solutions.
    The background to the invention is also described in publications PCT / NO2001 / 00079, PCT / NO2003 / 00004 and PCT / NO2005 / 00013. It describes a basis for the invention which is to achieve insulation between the lines in which are originally electrically interconnected so that the signals which are not equal or coherent should not interfere with each other. In the above-mentioned inventions this has been achieved with ferrite cores and by decoupling shunters and in bidirectional communication by dividing the usable frequency range into different bands for forward and reverse direction. The mentioned invention also describes an important basis for the present invention which is that A / D and D / A interfaces are introduced in transponder or repeaters that are nodes to condition infrastructure to optimize the use of these bandwidths. In electricity networks where the network is useful for a limited frequency range in relation to reaching bandwidths such as 20 25 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. competes with FTTH, there are major challenges in utilizing all available bandwidth on the cables. PURPOSE The purpose of the invention is in the future, when it provides sufficiently low delays, jitter and sufficient bandwidth to use available industrial devices from open or protected standards as far as they are presented, but so that their system properties are maintained or improved. Examples of such standards are 802.11x and WiMAX.
    The purpose of the invention is therefore to provide a stable connection and bandwidth for open and proprietary standards for small and medium-sized bandwidths or systems where real-time requirements are moderate. The invention works here either by allowing the use of high frequencies which involve the surface of signals from problematic frequency ranges for noise genomes through the use of repeaters or that the distance attenuation attenuation along a medium where "line of sight" or dynamic topology should not determine. Examples of standards that inventions can benefit from in the above-mentioned way are low-end PLC and at higher frequencies, 802.11x and ZigBee.
    The purpose of the acquisition is through standardized equipment to utilize the professional quality found in the above-mentioned equipment for various properties such as QoS Quality of Service Multicast.
    The purpose of the invention is through standardized equipment to utilize the professional quality found in the above-mentioned equipment for various properties to take advantage of "mesh", "grid" and star topologies and combinations of these.
    The purpose of the acquisition is also to provide new solutions to ensure the competitiveness of the placement. Furthermore, the purpose of the invention is to ensure that these improvements in stability and Quality of Service are not destroyed when it has 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. achieved connection to and from the user, CPE, by which is meant the customer's area.
    The background for the application of the invention is also described in publications PCT / NO2001 / 00079, PCT / NO2003 / 00004, PCT / NO2005 / 00013 and PCT / NO2006 / 000137. One purpose of the invention is to promote data communication, as close as possible to the customer's communication nodes without interference and problems from the shadow will affect the stability of data communication. One object of the invention is to utilize and in some cases improve the insulation between lines which are initially electrically interconnected so that the signals which are not equal or have coherence do not interfere with each other. Such purposes may apply if the interfering signals use the same frequency range, or even if they use different frequency ranges.
    Thus, the means to prevent crosstalk in-band and out-of-band. In the above-mentioned inventions this has been achieved with ferrite cores and by decoupling shunters and duplex communication by dividing the usable frequency range into different bands for to and from. This gives a further purpose of the invention which is to utilize that said published inventions make it possible for practical objects to multiply the available bandwidth of a cable by the number of cables used, even if they are already electrically connected and cannot be separated electrically or mechanically. The above inventions describe another important basis for the present invention which is that A / D and D / A interfaces are included in transponders, or repeaters found in nodes to optimize the bandwidth of the infrastructure. An object of the present invention is also based on the properties of said, published inventions for connection and disconnection solutions play a significant role in reducing crosstalk and use of infrastructure or cables' usable bandwidth. Characteristic of such purposes is safe and simple installation that should not interfere with other activities related to the infrastructure. One purpose of the invention is the maximum utilization of the increased 20 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. analog bandwidth that it offers by taking advantage of isolation between breakpoints, by amplifying the signals at the same frequency without frequency transposition. Another object of the invention is a new way of dividing the available bandwidth into analog frequency bands with mutually low crosstalk levels according to. principles-as described, in PCT / NO2006 / 000137.
    Another purpose of the acquisition is to utilize favorable topology in infrastructure such as electricity networks belonging to electricity companies and electricity networks in buildings with many units. Consistent with this purpose, it is necessary to solve the electrical and practical challenges that arise with cable nodes in order to achieve a system that is commercially usable and that is industrializable. An additional basis found in the published inventions in that they describe the use of "g" utilization backbone "as the present invention, can make maximum use of in order to make the best use of the infrastructure topology and usable bandwidth in the infrastructure included in the present invention where a method is by use of cable modem technology (DOCSIS) and hybrid cable technology (HFC).
    Such objects are in particular the use of the standard ITU-T J-222 (DOCSIS 3.0). A key goal of the acquisition is to utilize end-to-end infrastructure to provide an alternative to building connectivity all the way to customers in order to achieve lower costs, less general disadvantages, and which can be deployed significantly faster, but which also have the least competitive bandwidth. with 100 Mbps fl requests to the home (F'l'l'H). At least in this context, it is an object of the invention to solve the special challenges such as large discontinuities in the customer's cables in the power supply network, both the electricity companies' networks and the electricity networks in buildings. The purpose is equivalent to solving these challenges without the signals on the trunk line, from which customer cables are branched, being affected by the above-mentioned discontinuity on the customer's cables.
    Likewise, the purpose is to make maximum use of the fact that the main cables or main cables alone, apart from distribution points, have relatively moderate discontinuity. The purpose is to take advantage of the fact that there is a great continuity between distribution points as the main lines in the electricity networks in both those that use low voltage and those that use intermediate voltage between substations. Purpose 20 Date: 25.02.2009 PCT / N 02009 / _ Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. with the invention is also to enable remote reading of electricity and other types of meters in which the invention can be distributed specialized for such purposes, but with upgrade options all the way up to full triple play capacity. Especially in this regard, it is an object of the invention that remote sensing and human to machine purposes (M2M) should be done completely over IP interfaces.
    The format makes it possible to scale through the number of cables, the size of frequency ranges, the number of frequency channels, the number of active distribution lines and the VLAN level in different distribution points. Another goal is to offer the most possible bandwidth capacity on the electrical infrastructure and other infrastructure to make bandwidth available to almost anything that needs, preferably over IP interfaces. For such purposes, among many examples are micro cell WLF1, femtocell communication, television surveillance, various tasks for condition monitoring, various purposes for redundant communication capabilities.
    In summary, the purpose of the invention can be said to be to identify issues that, have done a very large number of projects worldwide before "No New Wire" has failed with stability and predictability and further create innovative solutions for the many parts relevant to such systems so that the problems were solved. There are other uses for the invention such as utilizing running wires in railway systems and other railway or traverse control means to achieve a stable two-way communication with large bandwidth available objects over longer distances.
    In the same way, uses have been found of the invention where the inconvenient infrastructure for railways and the like can be used to easily assemble dedicated wires for high transmission speed communication services, where assembly and complexity can be easier than using insignificant metallic lines. Nevertheless, your applications of the invention include the use of waveguides similar to infrastructures such as gas pipelines, water, sewage, for example to communicate over shorter distances which would otherwise involve very large 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement For stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. costs for installation of new infrastructure. An expert in the subject will be able to see more other applications of the invention.
    THE INVENTION The invention makes it possible to combine inventions in PCT / N0200600137 with equipment of open standards such as DOCSIS and DVB without bit error rate BER and jitter worsens the quality of services in critical service desolate applications to the embarrassing extent where problematic media with dispersive properties can be a prominent problem. The invention also makes it possible to accept available and appropriate proprietary standards.
    The invention makes it possible to combine standards in the same system. The invention made it possible to combine open and proprietary stand-hunting systems.
    The invention makes it possible to use accepted standards without radical changes in order to take advantage of these standards, for efficient production of telecommunications services in the so-called "No New Wire" concept.The purpose of the invention is to make standardized technology available for use by the most critical service fl fates over alternative infrastructure for which these technologies are not designed or in so-called No New Wire concepts.
    The invention uses a synergy of the lowest layers of DOCSIS and DVBc standards using repeater based power grid systems to avoid packet loss demanding services such as IPTV with MPEG4 to offer repeatable, commercializable quality. More specifically, it should be applied in link and physical layers in the OSI model. The repeater-based system of the invention ensures that the carrier-to-noise ratio remains virtually unchanged regardless of the distance from the headend or from the node point where the headend signals are spread.
    The acquisition can take advantage of the fact that it is optional if you want to connect to the link layer or the physical layer. In addition, the invention takes advantage of the fact that it is possible to connect with different choices of link layers and physical layers in the different repeater positions. The repeater-based system without the above-mentioned synergy provides a quality of service that is practically the same as with 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement For stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. coaxial cable, fixed within a limited frequency range. BER with the recovery will be acceptably higher despite different dispersion properties and variations in the signal medium. The invention thus enables, through any or minor modifications to such standardized equipment, high-quality services for those who are most likely to use them.
    The invention contains new solutions to provide sufficiently efficient industrial development in competition with more expensive, alternative technical solutions.
    The invention means that connection and disconnection, which can be destructive for stability and Quality of Service, can be done industrially or which makes it shake packages or combinations of these.
    The increase gives a high degree that the improvement of stability and Quality of Service is not destroyed the last bit from the point in the user's area where the increase achieves a stable connection and up to service units and service nodes. An example is when there is a stable connection to a broadband modem and further connection to a digital TV set via wireless routers or via Powerllne adapters such as HomePlug.
    With an embodiment of the invention, the insulation between differentially connected lines is improved with a small physical adjustment unit provided with a short physical distance from the conductors which are differentially connected. The invention achieves insulation with a series impedance in each differential conductor as well as a low impedance shunt between said conductors for shunt impedance which in its simplest form consists of a capacitor. In many constructions of the invention, serial impedance consists of toroids, dielectric toroids eg impedance of one hundred or more micro-Henry inductance.clamp-on ferrite toroids, dielectric toroids e.g. when they consist of an isolated conductor inductance alone because their relatively short conductors will be able to provide impedance of one hundred or so micro-Henry inductance. The differential conductors in an electrical network infrastructure will normally be two out of two, three or four conductors. The invention also uses different frequency bands for full duplex in both directions on the ordinary cable from which the various consumer cables branch or even on distributed main cables from a first main cable. A device of the invention uses a third frequency band for the customer's cable, ladder line or consumer cable between the node in the distribution point and the consumer or customer. Some versions of the application may be satisfactory.att-jariå / ånda 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. half-duplex communication where certain versions of the invention may use the standard spread spectrum similar to oFoil / ignaseraaelenneter (Homemuš), which uses half-duplex in the frequency range from 2 to 30 MHz.
    The extension makes it possible to increase the bandwidth in the system with a number of cables at the same distribution point which in many embodiments of the extension are signal-wise properly isolated from each other. Such signal-insulated cables can thus transmit different signals on the same frequency without significantly interfering with each other. This can apply to signals with the same information as real-time protocols or signals with different information, such as the Internet or different IPTV signals. Examples of different signaling different cables in the same distribution point are substations in the distribution point in the power supply, junction boxes or junction cabinets, distribution point in air cable systems, panels and cable distribution in buildings, industry and communication infrastructure. The invention enables transmission of these different signals to take place without crosstalk reducing the signal-to-noise ratio or increasing the bit error rate. In some constructions, some constructions can use the main cable, from which branching takes place, use separate frequencies for upstream and downstream signals. The extension therefore makes it possible to use full duplex along the main cable or the trunk cable and thereby it becomes possible to use gain at the same frequency by keeping the loop gain negative. The invention thus achieves minimal collision problems along the main cable or trunk cable and thereby avoids that boundary lines affect the capacity of the main cable and thus the capacity of the boundary cables is not affected either.

    Due to insulation against other lines on the branch or customer line, half duplex can be used without any significant impact on the system as a whole. An important part of the invention is to prevent the signals from having to pass parts of the infrastructure that deviate from resembling transmission lines. This means that the signals only need to pass along cables or wires, and that they must be connected and disconnected without being connected to the structures that do not behave as good transmission medium. This gain dramatically increases usable bandwidth, in part due to reduced unwanted parasite impedances, which increases on 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. maximum frequency for usable frequency range. The following features include the fact that the symmetry leads to a lower free-range coupling: lower, ep'ij $ iionsñevåbetter immunity. The invention solves this at the same time as factors that interfere with other operation of the infrastructure are kept to a minimum. The invention with certain designs further increases the system's analog bandwidth by using maximum bandwidth by amplifying signals at the same frequency without frequency conversion. In some constructions, the gain also utilizes the increased bandwidth by dividing the available analog bandwidth into your frequency bands in which the gain makes it possible to have mutually low crosstalk levels. In some constructions, the design makes it possible to easily create passive bypass connections at branch points where it is desirable to branch signals. Likewise, the invention makes it easy to mount active by-pass connections with an amplifying repeater in at least one direction said branching points to maintain the signals and maintain immunity, which will have special value in networks with air cable.
    The invention makes use of the fact that the electrical infrastructure is accessible at short distances for conditioning signals so that their quality is not lost and parameters such as immunity are maintained. The invention is therefore focused on solving the major challenges that arise in connection with interruptions in infrastructure, both electrical and practical. The invention takes advantage of the fact that infrastructure can have good properties for signal transmission between infrastructure components with discontinuity. In many embodiments of the invention, so much bandwidth will be managed right up to the user or customer that significant distribution points such as in a network station must have made light or dark connections in order for the available bandwidth to be fully utilized for the customer. In many constructions of the invention, the bearing connections will be part of a bearing ring system. The extension makes it possible to place fi requests further ahead to the customer such as to one or fl your branch points along the main lines so that more bandwidth can be fed to nodes and greater bandwidth can be distributed to customers over the last distance with electrical signals such as by A / D and DIA and OFDM modulation. In some versions of the invention, in the same way as fi ber, coaxial cable can also be used to increase the bandwidth to i berring i 20 25 Date: 25.02.2009 PCT / NO2009 /.

In some versions of the invention, a mixture of these solutions can be used to perform bear access. The invention uses in your versions that there is some discontinuity along the main lines along the main line in the way that communication over the above-mentioned distance is made as possible independently of communication over branches. Thus, the invention achieves that communication along the main line is stable and predictable. In your versions of the invention obtained a separate frequency range delimitations. In such constructions of the invention, all delimiters use the same frequency range. However, in these constructions, isolation between the lines means that the boundaries do not interfere with each other in that isolation between the boundary lines is large enough to provide sufficient signal dynamics for each branch. Typical requirements for the dynamics of a delimitation will be 30 dB for 256 QAM plus cable attenuation on average 15 dB, a total of 45 dB. If this dynamic has a smaller or larger dynamic range, some versions of the solution give that packet collisions, or carrier record delimitation, the delimitation with half-duplex communication does not occur due to the fact that PHY on each delimitation has signal dynamics that are greater than isolation between the delimitation lines. In some versions of the invention, separate, dedicated Quality of Service (QoS) for bandwidth on the branch communication has been used in the best possible way for the most demanding protocols such as UDP, independent of the communication on the main cable and on other branches. The purpose of the inventory is also to enable tar reading of electricity and other types of meters in which the inventory can be distributed specialized for such purposes, but with the possibility of upgrades all the way up to full triple play capacity. In some versions of the invention, the customer unit communicates the upper boundary line from the main line, placed in the electricity meter with eringltreringal] disturbances from the dwelling, apartment 'or Iiknåride; Especially in these applications, the purpose is for the acquisition of remote analysis and machine assignment (M2M) can be done completely over the IP interface. Another purpose is to enable the largest bandwidth capacity along the electrical infrastructure that is found virtually everywhere, and similar infrastructure to make bandwidth available to almost anything that needs communication bandwidth and where the IP interface is preferred.

    BRIEF DESCRIPTION OF THE FIGURES Figure 1 shows blocks schematically how the invention uses a synergy of the lowest layers of standards for telecommunications.
    DETAILED DESCRIPTION Fig. 1 shows that the invention consists of infrastructure 9, with connection points 3 between the segments 9 of infrastructures connected 4 to repeater 2 and tools 5 from standards for telecommunications are connected on the link layer 7 in the OSI model and the physical layer 8 and attached standards linked together on layers higher than the link layer.
    The invention combines different standards in different ways by linking a standard to the link layer or the physical layer. If the invention is to use the same modulation as this standard, it will normally be optimal to connect to the standard's physical layer directly, if necessary through a frequency converter. By connecting to the 'link layer to the suppfifi nningenka-n * use another type of jmotlüléiring which is very well belonging to the physical lagrètïïai such a modulation could also be implemented in the repeater of the invention. Repeater can be part of signal hub or «hub» as described in PCT / NO2006 / 000137 with related publications. In the above-mentioned signal hubs, signals such as using the same frequency amplification in both directions can also divide the frequency spectrum into fl your frequency bands for different frequencies for different directions. The invention can thus achieve individual signal processing for different directions and lines and which is based on the existence of isolation between directions and lines that can be used. The excitement; Some designs may be of different types. of modulation in different parts of the jsystemfutan the upper layers of the carbon communication protocol need to give disturbing time delays or tannannannl significant. The purpose of using different carrier frequencies, different modulation types and different communication interface layers will mainly optimize the results. Such optimization should be based on the information carrier 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. or infrastructure fl its varying fi characteristics dependent. on the çvainfinämnga properties current route, or area _ Signal hub or hub and client devices described in PCT / NO2006 / 000137 with associated publications, can in the invention at any point in the system be realized by demodulator - modulator. Likewise, the mentioned system solutions in the invention with the signal node plants in the present invention can also utilize achievable insulation between the rows in other ways. In different versions of the invention, lines can be customer lines from cable cabinets or from post-voltage low-voltage networks, and in other versions, lines can be departures from the network station. In this way, the signals on different lines are prevented from interfering with each other. Such signals will not be connected directly to each other. Such signals will thus be able to utilize the available analog bandwidth of the individual lines, for example, each line has its own demodulator-modulator. Another example of the above-mentioned system solutions in the invention is in points with signal hubs to use modems in combination with available products that modulate and demodulate with a different type of modulation and protocol. The connection can then the connection between the modem and products mentioned happen on a higher layer than link layer such as IEEE 802.3 interface. In a large head. distribution point clettaofta becomes a Gigabiggränssrïitti In the example above, the time delay may be acceptable because the interface is not shared or shared by a limited number of users or services. Among the many advantages of the invention is that Master-Slave units at affordable prices can be used because slaves, due to the signal hub described by PCT / NO2006 / 000137 with associated publications, can only communicate with Mastar. In the original version of the invention, the 'master's units assigned to the dsmseparatá lines are used or that one and one master unit is signal-connected to two or more of the separate lines.
    Adequate use of insulation between the customer lines can be ensured by individual control of reinforcement and attenuation as described in said publications.
    An example of an embodiment of the invention is the use of DOCSIS cable modems from the headend and in severe cases, using modems and HomePlug from the main cable and to the customer through the customer's branch cable. In the above 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. mentioned construction, the modem may be DOCSIS 3.0, which may contain fl your physical modems. Another example of an embodiment of the invention is the use of DOCSIS Modular Central (M-CMTS) for Edge QAM where the Edge QAM interface is used to modulate OFDM modulation. Such OF DM modulation can then take place in a version of the invention using transmodulation back to the QAM at the customer and then used together with standard, low cost cable modems. The invention facilitates industrialization and commercialization by so-called "do it yourself kits" can be distributed to customers in apartments and the like without installers need access.To ensure that the success of these packages is as high as possible, a version of the invention also connects between different interfaces on different communication layers.The invention uses in many versions for Power Line Communication that high level of interference in the home or the apartment has minimal effect on the return transmission when the excitation effects are OdBm or more.So, in a representation of the invention, the return transmission can be connected through a client device connected to the wall socket in the home, preferably as close to the fuse box or customer cable as possible. in a performance ng of the connection to the downstream signal at a higher frequency that is less sensitive to has a lower level of interference. In a power inlet or fuse box, another client device is installed in an embodiment of the invention which means that the return signal can pass passively with little attenuation or that the client unit actively converts frequency up to a higher frequency for more efficient reconnection not with galvanic coupler. Said client unit is oriented so that it receives the downstream signal through a loose connection which in the representation of the invention is installed by the customer. Such loose connection can be inductive or capacitive connection and not galvanic and have an motlter against the home's electricity network which can consist of the electricity meter. Said downstream signals are frequency converted up to a second frequency which the aforesaid customer unit receives at. The aforementioned frightened device karin is often connected directly to an open istårildïårid modem or contain a device likiflialniçle sdr fiärinlndarrtodem. The first said client unit shall usually contain frequency conversion to be compatible with said modem. Said solution with two client devices can also be an installation of technicians to achieve fl surface connection of the modem and Ethernet- 20 Date: 25.02.2009 PCT / NO2009 /.

In order to "improve the above" solution and increase the distance between the power supply and the connection point, the power cable can be associated with an electrical socket in the invention equipped with a device which prevents the power consumer connected to the said power cable from destroying its symmetrical properties. In an alignment of the device consists of the affected plant of a lid with plug and female connector or she to he plug which is connected to the wall socket. In a representation of the invention, said cover or plug contains ferrite toroids with air gap and capacitive short circuits for differential signal so that consumer devices for electrical connection shall not affect said cable its signal properties in the invention. Such a system with a lid or plug may be in a representation of the invention used to transport signals between client units and conditional point house. Such signal routing may be in a representation of the invention made in connection with the upper layers of used communication protocols used around the home, as in a representation of the invention is HomePlug or Home Alliance, even when it comes to the physical layer which to be transmitted on the cable network in the home. In one edition, said unit for a power outlet is a cable with connectors at both ends that can connect two mains circuits in the home for signals but which acts as a stop for the mains voltage. The mentioned cover with plugs for electrical outlets is in a version of the invention also a mechanical and current-related host for radio units which may have conditional information. Such a structure of the invention is in a further embodiment oriented so that it frequency converts said radio unit its signals to more suitable frequencies, which can utilize said cable's improved signal properties for transmitting said more suitable frequencies on electric cables in different parts of the property. In some versions of the invention, the connected client unit that communicates with the node that branches from the electricity companies' main cable in the distribution system is connected directly to an electrical outlet in the apartment for both transmission directions, when it is accepted that the most demanding protocols will not be used.
    An idea of the invention ensures that industrial utilization is not significantly reduced from problems with connection to cables in low-voltage networks, both outdoors, in buildings and apartments as a result of irrational installation 20 Date: 25.02.2009 PCT / NO2009 /.

In the above-mentioned construction of the invention the problem is solved with a geometric, symmetrical connection in place critical places with low current clamps which in its simplest version of the invention is a plastic band around insulated conductor and where a contact screw is threaded through said plastic band and for electrical contact to conductor , and that the device has a signal cable connected to said contact screw.
    The design of the wire where individual wire is used as a medium utilize the wire that there are very low losses along the wire compared to the spherical attenuation of a radio link budget. Even in insulators in poles, the losses will be negligible because wires on each side of the insulator act as couplers to each other. Even with the implementation of the invention of using wires for feeding operation of electric locomotives, the above-mentioned, low losses will be present for suitable frequencies. Similarly, a version of the invention is wires that extend along roads and streets for wireless coverage, such as in poles for street lighting. In some versions of the invention, two or more frequency bands with a relatively large frequency difference between the frequency bands are used. In these constructions, the said is used to introduce redundancy due to various factors such as snow and ice on the wire. By means of transmission on said wire, path interference is reduced, which is of great importance for stability. The invention utilizes these low line losses by accepting less optimal connections and disconnections for repeaters and transponders that are mounted in connection with the line. The recovery can thus be done with the help of standard antenna solutions such as probes that are mounted relatively close to the line. Also, for some constructions of the invention, a simple, direct connection to the wire is sufficient. Such a direct connection is particularly suitable for low-voltage network wires pole system, and on ground Iinja in general in pole systems. Although the connection and disconnection loss with said connections together is high, it becomes less important with increasing distance because the line loss is small compared to free sight loss, Fresnel zone edge loss or loss with radio link without free sight. In different versions of the invention, therefore, repeaters are simple and inexpensive. In a representation of the invention, radio units intended for radio may be mounted in a suitable box directly on the wire with the correct distance between repeaters. In a representation of the invention, the same antenna is used for connection to wire which comes with 20 25 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. this radio device. Thus, the invention also allows the use of standards without making interface contacts on the physical, link or other law when radio units for the above mentioned standards can be configured as repeaters and time delays do not pose a major problem. An example of this embodiment of the invention is the ZigBee radio installed at the appropriate point on the line. Other examples of this version of the invention are the corresponding use of 802.11x radio devices. Such versions of the invention provide significantly reduced immunity problems in split frequency bands and reduce the requirement to use mesh and other dynamic topologies. In one version of the invention, said advantages can be exploited by hanging metal wires for specific applications of said embodiments of the invention. In such constructions of the invention, it can, despite no direct visibility, indoor obstacles and floor obstacles in buildings and houses, establish one hundred percent reliability and connectivity and Quality of Service even for real-time protocols. In the designs of the invention, metal wires can be made very thin or almost invisible, for example with nylon wires vapor-deposited very thin layers of metal. In one embodiment, threads are decorative with, for example, candles. In some versions of the invention, it is necessary to have transponders on or near the line to have a link with wireless devices that use connection and disconnection to the line. In other versions of the connection, radiation loss along the line is sufficient to obtain a stable connection link for wireless devices which without the said line do not need to be connected at all. In the same way as for the individual wire or: cable, in which simple antennas function as * sondêr ° t.i | l> in_frastructure which can function as waveguides fi fxspecially röifforrñadšinfråstrüktur zur plastfeller metal. One embodiment of the invention is the connection and disconnection of the microwave radio which is mounted up to a plastic tube which acts as a waveguide due to plastic to gas dielectric contrast, plastic to surface or plastic to solid matter dielectric contrast. The design of the invention in the terrain where low voltage power supply is not available, the invention uses solutions for the supply of energy to repeaters, transponders, signaling hubs, Bridger routers and access points that are necessary in the system. In a solar cell version with the invention, a rechargeable battery is used. In another embodiment of the invention, the standard industrialized toroidal power supply is used for power lines. In another construction where there 20 30 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. the requirement for energy is less, the invention uses electrostatic probes with electrical insulation for nearby high-voltage lines that supply power to the electronics. In a version of the invention, the probes consist of standardized, shielded high-voltage cable where the screen of a certain length is used for power outlets. During implementation, the cable is treated as a normal termination with regard to insulation, currents and water-repellent. In a representation of the invention, probes consist of wire or metal rod. Through a different design for lines where there is a large force load, the winding uses a telecoil at a suitable distance from the high voltage joints. In addition, in one embodiment, the invention utilizes a transformer in the form of an entomoidoid core around the high voltage conductor to function as a power tower on the primary side. Such transformers, in addition to a secondary winding, have a winding which acts as a short circuit of the transformer and which is controlled with a high frequency by an electronic device. Said electronic device can be driven by the transformer, but in one embodiment of the invention it receives energy from a starting battery and solar cell and then keeps shaking. Such toroidal cores should preferably enter saturation of the current flowing in said high voltage conductor. In your versions of the invention, a small analog interface adapter is used which is connected with differential connection through two short conductors connected to two conductors in a cable with compact cable clamps that allow connection as early as possible before the cable conductors are spread before the cable is connected in a cable distribution point. The two short conductors should not be longer than 10 cm to be tunable and use the available bandwidth of the cable which can be 100 MHz. The two short conductors with their inductance are tuned in resonance at the highest frequency of the current cable, with a capacitor in the said adaptation unit and thus give a differentiated filter in connection with the said short conductors its impedance and odd impedance. The said two short conductors are the piston plate to the adapter through its high voltage capacitor f as É-Ifíiljer deii from the live cable being connected. The cable impedance, which will often be in the range of 30-40 ohms, is converted in the fitting unit to a suitable impedance for the signal cable emanating from the said interface unit and to the unit to be connected and the cable may be a standard telecom cable with twisted pairs. In some versions of the invention, a 20 30 Date: 25.02.2009 PCT / N 02009 / _ Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. indicator light in adapter and shunt that indicates electrical connection to the power cable to facilitate installation and subsequent control. In a representation of the invention, the fitting unit is also provided with a component which acts on overvoltages past sensitive components * therein which can be an important network with an air cable. In some versions of the invention, the adapter includes choke filters between the voltage side of the connector and a separate cable for supplying power to active devices in conjunction with the adapter. In some versions of the invention, the above adapter contains at least one common mode choke. In some versions of the invention, said adapter comprises high frequency transformer interfaces for galvanic isolation for better management of overvoltages and to lead them past signal components. The invention consists of devices for signal isolation. .To achieve the best possible insulation between the lines on the trunk line, the two adapter units for the trunk line can be connected to different conductors on the main line cable. In many constructions of the invention, the system has a shunt impedance associated with the adapter. In this way, the invention achieves greater insulation, in this example by undesired coupling, having to go through at least three sections, the minimum of which will consist of inductor-like ferrite cores mounted on at least two conductors, at least one shunt impedance, at least one shunt impedance. shunt impedance, and finally again, impedance, which may consist of, ferrite cores of at least two conductors In some versions of the invention, shunt impedance instead of a capacitor with short connection conductors may consist of an alter network consisting of capacitors and conductor inductances in this way to achieve lower shunt impedance for higher frequencies through broadband series resonance with the inductance adjacent to the shunt impedance. Connections to the impedance hiccup thus in visšaiversionierwav the invention consist of their insulated conductors as auxiliary of the capacitor network with the mutual resonance of the conduction inductance over the frequency of the dékiadeiriíi frequency. The capacitor network can consist of ceramic capacitors with low rated voltages because the shunt unit also contains a range of high voltage capacitors for separation to 50 or 60 Hertz voltage. In these versions the isolation with signal isolation is achieved that damage due to overvoltage on the trunk line is limited and that the associate monuments »Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. will be all the more preoccupied with injuries' as a result. The differentiated conductors will, in a Kraftnät infrastructure where the invention will most often be used, normally be two from two, two from three or two from four conductors. In some versions of the invention, two and two conductors in four conductor systems will be used for more efficient differential transmission. The invention uses different frequency bands for full duplex return on the main cable from which the various consumer cables branch. In some versions of the invention, individual frequency bands for return are divided into additional frequency bands or channels so that a constant bit rate on each channel can be achieved. The lowest channel in an underground cable system will have dynamics of 5 to 20 dB between repeaters, while the highest channels that Upp fi nningen allows to use will have dynamics of 20 to 40 dB between repeaters. In overhead cable systems, the corresponding figures will be 2 to 5 dB and 10 to 30 dB. This also enables the invention to use more efficient modulation such as 256QAM and 1024QAM on a continuous basis. With this, the acquisition achieves redundancy so that all branch points and branches have more possibilities for channel selection to achieve a stable bit rate into the branch points. The invention can achieve this directly by using cable modem technology on the main line with, for example, downstream channels placed shoulder to shoulder as well as a number of upstream channels in the second frequency band, also shoulder to shoulder. In the branch points, some embodiments of the invention will mount cable modems which in turn are connected to a communication unit with a different type of protocol and PHY towards the customer where such protocol and PHY can consist of bridge functionality at MAC level with PHY using OFDM modulation and half duplex such as with power line devices (HomePlug). In the mentioned embodiment of the invention, it will be useful to have one cable modem and an OFDM power line unit for each branch. In some embodiments of the invention, it may be sufficient to use one cable modem at the branch point where it is connected to a switch or router which in turn is connected to power line units where such a power line unit is used for each branch. In the said embodiment of the invention, each branch may be part of a VLAN with a standard that supports Quality of Service and IGMP.
    Similarly, an embodiment of the invention is that a cable modem is used in the branch point which is in accordance with the cable modem standard ITU-T J222 (DOCSIS 3.0). Hereby the achievement achieves both to be able to bundle channels on 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. various levels including MAC level for greater maximum bandwidth as well as VLAN against the branches. The invention makes it possible to increase the bandwidth of a system with a number of cables at the same distribution point as in many embodiments of the invention are signal-wise isolated from each other. Said signal-insulated cables can thereby transmit different signals in the same frequency range by means of connection with adapters and insulation by means of ferrite toroids and shunt impedances.
    By the fact that frequency bands for connection are the same on the different cables and that frequency bands for disconnection are the same, the invention achieves that insulation between the cables is sufficient for 40-50 dB dynamics which is abundant dynamics also for constant, non-adaptive modulation with up to 1024 QAM so as long as PHY does not use half duplex with carrier detection and anti-collision routines with high dynamics. Examples of the mentioned use of different signals on different cabins at the same distribution point are substations in electricity supply including pole-mounted substations, junction boxes or street cabinets, distribution points in overhead cable systems, switchboards, cable distributions, fuse boxes in buildings, industry, communication infrastructure, homes, apartments. The invention in some embodiments utilizes that the main cable from which branches take place uses separate frequency ranges for return and return signals, even though the available analog bandwidth on said main cable is marginal. The invention therefore makes it possible to use full duplex along the main cable or the main line to achieve the most stable downstream bandwidth possible. Thereby, the signals can also be amplified at the same frequency in order to make the best possible use of the bandwidth of the cables. In some embodiments of the invention, duplex filters with a maximum appeal pitch of a few Megahertz and high stop band suppression are used so that the loop gain becomes sufficiently negative despite internal loop coupling in repeaters, external loop coupling through units consisting of said adapter and said signal isolation devices and devices. despite marginal analog bandwidth relative to the transmission speeds to be achieved. With 40-50 dB isolation, stable same frequency amplification can go up to 25-40 dB depending on the type of same frequency amplification used. In this way, the mentioned embodiments of the invention achieve coherent reinforcement with the lowest possible levels for phase noise and beating, as well as dynamics that are only limited by the loop reinforcement. In some embodiments of the invention, preemphasis, deemphasis and 20 Date: 25.02.2009 PCT / NO2009 /. Title: Signal repeater system arrangement for stable data communication. DESCRIPTION. Swedish translation from English, 25.11.2010. equalization to control negative loop gain, reinforcement and stability, especially during roll-out and assembly, but sometimes also with advantage during operation. In some cases, such as with overhead cables where points for mounting repeaters are available everywhere, some embodiments of the invention will not need to have more than 10-15 dB net gain for the highest frequencies and for the lowest frequencies with the least loss the gain can even be passive and negative. In some embodiments of the invention, passive bypass connections are made between at least two main lines at branch points where it is not desirable to connect signals to branches. Said bypass connection is made by connecting the signal cables to two copies of said adapter. Said bypass connection will typically be useful in Iuftkabel systems. Similarly, the invention makes it easy to mount active by-pass couplings having reinforcing repeaters in at least one direction in said branch points in order to maintain the signals and maintain immunity, which will also have special value in overhead cable networks. In some embodiments of the invention, said passive bypass method is used in conjunction with half-duplex communication technology of standard or proprietary type. In some embodiments of the invention, said bypass can be performed as a passive hub where branches are also included.
    In your versions of the invention obtained a separate frequency range for the customer cables and In some constructions, this will be the lowest frequency range as it can be used OFDM with high interference robustness and tolerance to reactions.In the meantime, lower effective bandwidth as a result of OFDM will mean less because Customer cables are offered to handle this entire frequency band without bandwidth reduction due to other customer cables that will use the same frequency range. For 2-30 MHz, this will in most favorable cases mean more than 200 Mbps speed. Typical requirements for this in the dynamics of a branch will be 30 dB for 256 QAM plus cable attenuation, averaging 15 dB, a total of 45 dB. If these Üynamiker nilridreiellerstörre certain versions of the invention that paketkbllišioneneller carrier wave intäolšing intermediate customer cables with half duplex kpmmunikatiörí iñzê ü fi psrårtirrfølgediav au PHY; so varjelsund cable hair signal dynamics that are greater. than the insulation grneillan these cables.

This means that carrier detection and anti-collision functions will not use resources so that they lead to mutual interference between customer lines, even if they operate in the same frequency range and even if signal dynamics are greater than isolation between customer cables. At the same time, adaptive modulation will work normally. and provides stability in relation to interference and tolerance to variations in cross-talk levels. In some versions of the invention, the division of frequency for communication is applied to the customer cables _ In some versions of the invention, part of the frequency range is converted up to a redundant channel, while that part of the frequency is converted into a redundant channel, which is higher. the highest frequency range used by the main line. This makes it possible to extend the entire frequency range used by the trunk line down to frequency when the main line consists of cables with poor properties at higher frequencies or for long cables in the ground. In some versions of the invention, up-conversion is used only in a signal direction from the distribution point to prevent interference with the main cable. In other versions of the invention, said up-conversion is in both directions.
