Technique Field
[0001] The present invention relates generally to wireless system development and, in particular, to testing the performance of a wireless system configuration installed or planned for installation on board a complex system such as an aircraft. background
[0002] There are a number of wireless systems planned on commercial aircraft that include WLAN (wireless local area network), cellular, RFID (radio frequency identification), in-flight entertainment, emergency lighting, numerous airborne health monitoring sensor systems. emerging aircraft and the like. Individually, each system must face a single-aircraft environment. For example, the particular fuselage structure or interior cabin medication can make it difficult to determine wireless channel characteristics and overall performance in the aircraft. Temporal effects, such as passengers and crew moving, also complicate this and can create a performance impact. The problem is exacerbated when simple systems and protocols are forced to operate in close proximity, as is the case inside an aircraft. This results in concerns regarding unintentional interference and "data collision". Due to these factors, performance degradation can occur with field wireless systems and they may not function as expected.
[0003] Currently, performance degradation is mitigated in wireless field systems through modeling and testing processes. Testing, in this context, usually involves measuring or estimating the performance of a wireless system. Current testing methods have numerous limitations. Test processes are often performed on a wireless system installed in a test vehicle selected for convenience, but that vehicle is rarely equivalent to the location-specific configuration in which the wireless system is to be installed. Furthermore, even when using state-of-the-art equipment and experienced personnel, testing can take an extended period of time. In addition, standardization in testing processes and data format for a specific type of system can make it more difficult to share common data that may be equally relevant to different types of wireless systems. Current testing practices can make it difficult for programs to share test results, causing inefficiencies from a backlash of effort.
[0004] Accordingly, it may be desirable to have a method and apparatus that takes into account at least some of the issues discussed above, as well as possibly other issues. Brief Summary
[0005] Exemplary embodiments of the present description are generally directed to a system for testing the performance of a configuration of a wireless system installed or planned for installation on board a complex system such as an aircraft, and a corresponding method.

[00011] In one example, data collection may include collecting data in a center-radial array where a designated wireless monitor acts as a central monitor responsible for interrogating and receiving responses from the other wireless monitor(s). that function as node monitors. In another example, data collection might include collecting data in a mesh array where one or more of the wireless monitors selectively function as a central monitor or node monitor.
[00012] In one example, installation, emulation and collection may occur for a plurality of different configurations of the complex system, with each configuration being at least partially defined by parameters where one or more of them are different for different configurations. Additionally or alternatively, for example, installation, emulation and collection may occur for a plurality of different wireless system configurations of interest, with each wireless system configuration being at least partially defined by one or more of the same parameters, where the same are different for different configurations.
[00013] In accordance with one aspect of the present description, a data analysis system is provided which comprises a data store configured to store a collection of data from a plurality of wireless displays installable at respective locations aboard a configuration. of a complex system in which a wireless system of interest is installed or planned to be installed, the wireless monitors are configured to emulate the wireless system of interest, and record data related to the performance of the wireless system of interest on one or more times recorded in a plurality of operating conditions of the complex system, the data collection includes the respective wireless monitor locations correlated to respective recorded data and recorded times; and a data analyzer coupled to the data store and configured to perform an analysis of the wireless system of interest based on the data collection, the analysis is performed to establish a configuration of the wireless system of interest that meets or exceeds at least one design requirement, the data analyzer is configured to compute whether the configuration or operating conditions of the complex system allow the wireless system of interest to operate with a wireless link quality specified by at least one design requirement.

[00028] Some embodiments of the present description will now be described more fully below with reference to the accompanying drawings, in which some, but not all, embodiments of the description are shown. Indeed, various embodiments of the description can be incorporated in many different ways and should not be construed as limited to the embodiments presented herein; preferably, these exemplary embodiments are provided in such a way that such a description is perfect and complete, and in order to fully bring the scope of the description to those skilled in the art. Equal reference numerals refer to elements throughout.
[00029] Exemplary embodiments of the present description generally refer to wireless system development and, in particular, to test performance of a configuration of a wireless system installed or planned for installation on board a complex system such as an aircraft. Exemplary embodiments may be described herein with reference to a wireless system installed or planned for installation on board an aircraft. It should be understood that exemplary embodiments may be equally applicable to a wireless system installed or planned for installation on board other complex systems, manufacturing/factory facilities, vehicles or the like, both within and outside the airspace industry.
[00030] Referring now to Figure 1, a wireless performance testing system 100 is illustrated in accordance with exemplary embodiments of the present description. The system may include any of a number of different subsystems (each individual system) to perform one or more functions or operations to test the performance of one or more configurations of one or more wireless systems installed or planned for installation on board a complex system. like an aircraft. As shown, for example, the system may include one or more wireless monitors 102 and a data analysis system 104. Although shown as separate subsystems of the wireless performance testing system, the data analysis system may, instead, be integrated into one or more of the wireless displays. Or the data analysis system can be deployed in a hierarchical computing environment where some processing can be performed locally on the wireless displays, while aggregation can be performed globally on the data analysis system. It should also be understood that either or both wireless test systems may function or operate as a separate system without being related to each other. And further, it should be understood that the wireless performance testing system may include one or more additional or alternative subsystems other than those shown in Figure 1.
[00031] An aircraft or other similar complex system may be manufactured or upgraded to include one or more wireless systems. Examples of suitable wireless system types include wireless local area network (WLAN), cellular, RFID (radio frequency identification), in-flight entertainment, emergency lighting, numerous emerging aircraft health monitoring sensor systems, and the like. These wireless systems may include numerous wireless hardware components configured to operate under one or more of a number of different radio access technologies. Examples of suitable radio access technologies include Third Generation Partnership Project (3GPP) or Fourth Generation Partnership Project (4GPP) radio access technologies such as Third Generation (3G), 3.9G, Fourth Generation technologies ( 4G) or similar that include, for example, Long Term Evolution of UTRAN (LTE), advanced LTE or similar. Examples of other suitable radio access technologies include Universal Mobile Telephone System (UMTS) radio access (UTRA), Global System for Mobile Communications (GSM) radio access technologies, access technologies Code Division Multiple Access (CDMA) 2000 radio stations, WLANs such as IEEE 802.xx, e.g. 802.11a, 802.11b, 802.11g, 802.11n, etc., worldwide interoperability for microwave access (WiMAX) , IEEE 802.16, and/or wireless PANs (WPANs) such as IEEE 802.15, Bluetooth, low energy versions of Bluetooth, infrared (IrDA), ultra wideband (UWB), Wibree, Zigbee or similar. In various examples, a number of these and similar radio access technologies can employ any of a number of different smart antenna technologies such as multiple input and multiple output (MIMO) technologies where multiple antennas can be employed to enhance communication performance.
[00032] A wireless system may be installed onboard a complex system in one or more of a number of different configurations where one or more parameters of the wireless system may be different. A configuration of a wireless system can be at least partially defined by one or more parameters of the wireless system. Examples of parameters of a wireless system that may differ between configurations include its radio access technology, modulation type (e.g. AM, FM, BPSK, QPSK, 64-QAM), carrier frequency (e.g. usually in the 10s MHz to 74 GHz and higher), antenna type and/or number, power level, or the like.
[00033] Like the wireless system, an aircraft can be any of a number of different types. The aircraft may also be manufactured in one or more models each, which may have one or more series and/or configurations. For example, the Boeing Company manufactures or has manufactured different models of commercial aircraft under the 7x7 model designations that include 707, 717, 727, 737, 747, 757, 767, 777 and 787. An aircraft configuration can be at least partially defined by one or more of the aircraft parameters. Different aircraft configurations may include different wireless systems, or the same wireless system with different configurations. Examples of other parameters of an aircraft that may differ between configurations include fuselage construction, cabin design (e.g. customer preference, class seating arrangement), materials used in interior components (e.g. glass or carbon fiber, carpet types, seat construction with built-in fire retardant material, insulation blankets) or the like.
[00034] In addition to having any of a number of different configurations, the aircraft can operate in any of a number of different conditions for a period of time. Examples of typical operating conditions include aircraft-level state-of-load conditions such as empty or loaded with passengers and/or cargo, flight conditions such as on land with doors open in a passage, on land with maintenance personnel, or normal in-flight operation. with passengers under various conditions (eg, seated with belts fastened, moving in the cabin), or the like. Other examples of typical operating conditions include aircraft or system level conditions such as temperature, active operation of one or more wireless systems, or the like.
[00035] As indicated in the preceding section, numerous variables in an aircraft environment that include an aircraft configuration and/or operating conditions can affect the performance of one or more wireless systems installed on board the aircraft. As explained in greater detail below, one or more wireless monitors 102 of the wireless performance test system 100 can be installable in a complex system such as an aircraft. The wireless monitor can be portable, small and easy to install and uninstall on board the complex system, and can be additionally easily configured for operation. The monitor(s) may be configured to collect data related to the performance of a wireless system installed or planned for installation on board the complex system (wireless system of interest). As described herein, terms such as "collect", "record", "capture" or the like may be used interchangeably. The monitor can adapt to various installations to accommodate complex system constraints, and can operate in one or more modes so that its data collection can be optimized or induced to wireless systems of particular interest.
[00036] In one example, each monitor 102 can be installed in a location on an aircraft such as its fuselage, and its location can be recorded on the monitor. As indicated above, the interaction of a wireless system with its surrounding environment and/or the moment at which the interaction can play important roles in its performance. Each monitor can thus be configured to record data at regular intervals, and correlate the monitor location with the recorded data and respective recorded times for a more complete analysis of a wireless system of interest. Still further, for example, the recorded data may be correlated to one or more wireless system parameters of interest, one or more aircraft parameters, and/or one or more aircraft operating conditions at the respective recorded times.
[00037] The data collected by each monitor 102 includes the correlated location, recorded data and the respective recorded times may be retrievable for analysis of the wireless system of interest. In this regard, each wireless monitor can be configured to pass its collected data to the data analysis system 104, which can generally be configured to combine data collected from one or more monitors and perform an analysis of the wireless system of interest with based on the respective data. Each monitor can collect data at the required fidelity from a wireless environment, which can allow the data analytics system to combine data from numerous (one or more) monitors for analysis. In one example, the data analysis system can be configured to compile temporal RF spectrum mapping and/or wireless system performance inside the aircraft fuselage. In one example, the data analysis system can be used in an offline and/or batch processing mode to analyze data; but in another example, the data analysis system can be used in an online and/or individual processing mode. The analysis performed by the data analysis system can be used as a basis for one or more conclusions regarding the wireless system of interest. For example, analysis may be performed to establish a wireless system configuration of interest that meets or exceeds at least one wireless system design requirement. In this regard, the analysis may include computing whether the configuration or operating conditions of the complex system allow the wireless system of interest to operate at a wireless link quality specified by the design requirement(s). In this way, from the conclusion(s), one or more decisions regarding the respective wireless system of interest, such as one or more decisions regarding its configuration, can be made.
[00038] Reference will now be made to Figures 2 and 3, which illustrate more particular examples of a suitable wireless monitor 102 and data analysis system 104, respectively, in accordance with exemplary embodiments of the present description.
[00039] Figure 2 illustrates a wireless monitor 200 that may correspond to wireless monitor 102 according to an exemplary embodiment. As shown, the wireless monitor may include a control module 202 coupled to a radio 204. The control module may generally be configured to control the radio to emulate any one or more wireless systems of interest, and cause transmission and receiving data during wireless monitor operation. The control module may also be configured to collect or receive, and otherwise measure or calculate other data based on the wireless system of interest and/or the data transmitted or received during wireless monitor operation.
[00040] In one example, data received or calculated by the control module 202 may include the location of the wireless display 200 on board the complex system, which may be absolute or relative (e.g. relative to one or more other displays) and acquired in any one of a number of different ways. In several examples, the local coordinates of a monitor can be manually loaded during installation. In other examples, the control module can automatically detect its own location according to any number of positioning techniques such as global positioning system (GPS) techniques or indoor GPS tracking/positioning systems, local positioning system (LPS) or similar. In one example, the control module can be configured to determine its location based on one or more values of time-in-flight (TOF) measurements or received signal strength indicator (RSSI) of transmitted impulse signals.
[00041] The data may include, for example, one or more parameters of the wireless system of interest, one or more parameters of the complex system in which the wireless module 200 is installed (for example, aircraft type, manufacturer and/or model), one or more aircraft operating conditions or similar. The data may also include, for example, data pertaining to the monitor, wireless system of interest, or complex system. Such pertinent data may include, for example, one or more maps and/or 3D models of the complex system, personalized notes relevant to the wireless display installation, or the like. In one example, this data may be manually added by a technician setting up a test, but other automatic mechanisms may be additionally or alternatively employed. More particularly, for example, the technician can manually load data such as aircraft, internal model, operational status, origin, destination or the like. Other data such as ambient temperature, pressure or the like can be automatically recorded and added to the data stream through augmented sensing.
[00042] In another example, the control module 202 may be configured to cause the transmission of one or more messages or other signals, and receive appropriate responses, via the radio 204 and one or more appropriate antennas 206. These messages and responses may be between the wireless monitor and one or more other wireless monitors in order to perform a poll/response, connectivity check, interrogation or the like. The control module can be further configured to receive, measure or calculate one or more message parameters or other signals and/or responses, from the examples which are provided below.
[00043] As shown, the radio 204 may include numerous layers such as a radio stack 204a and an RF and sound layer 204b. The radio stack may include or be otherwise configured to deploy one or more radio access technologies from the respective one or more wireless systems, any one of which may be a wireless system of interest. The radio stack can therefore be configured to emulate one or more wireless systems of interest. In one example, the radio stack may include a software-defined radio system.
[00044] Alternatively, a radio stack comprising a software-defined radio system may be configured to deploy one or more radio access technologies of respective one or more wireless systems that include the wireless system of interest; and a radio frequency and sound layer may be configured to operate and cause the transmission, reception and measurement of one or more network parameters of one or more waveforms through one or more antennas.
[00045] The RF and sound layer 204b of the radio 204 can be configured to function as the radio of an RF network analyzer to cause the transmission, reception and measurement of one or more network parameters in one or more ways of waveform (continuous and/or pulsed wave) through antenna(s) 206. Parameters may in turn be received by control module 202. Waveforms and parameters may be generated or otherwise selected according to any one of numerous different wireless channel models. In one example, then, the control module may include channel model builder 202a configured to build one or more wireless channel models according to which the RF and sound layer may be configured to operate and cause the transmission, reception and measurement of network parameters. Examples of suitable channel models include those based on s-parameters, impulse response, mean energy, energy standard deviation, energy variation, fading, depth, or the like.
[00046] In one example, the control module 202 may also include a link quality evaluator 202b configured to calculate the quality of a wireless link based on parameters measured by the RF and sound layer 204b of the radio 204 and received by the control module. The link quality indicator can be configured to calculate the quality in any of a number of different ways, and in one example, it can also be based on the wireless system of interest. For example, the link quality indicator can be configured to calculate the received signal strength indicator (RSSI), data rate and/or sent/lost packets for a WLAN system of interest. In other examples, the link quality indicator can be configured to calculate RSSI for a cellular system of interest, or poll versus response for an RFID system of interest. Other exemplary measurements of the quality of a wireless link may include channel capacity, bit error rate (BER), signal-to-noise ratio (SNR), or the like.
[00047] As also shown, the wireless monitor 200 may include data storage 208 coupled to the control module 202 and configured to store data collected by the wireless monitor, which may include data transmitted, received, measured and/or calculated by the monitor wireless. Control module 202 can be configured to collect data at regular intervals. The data store can thus store the monitor location correlated with the recorded data and timestamps of recorded times of the recorded data. Furthermore, the data store may store recorded data correlated to one or more operating conditions of the complex system at the respective recorded times. In this regard, the storage device may be coupled to an appropriate clock 210, which in one example may be synchronized across numerous wireless monitors of the system.
[00048] Although shown as part of the wireless monitor 200, it should be understood that in other examples of one or both, the channel model builder 202a or the link quality evaluator 202b may alternatively form part of a system analysis system or other external system, such as the data analysis system 104 of Figure 1. In these other examples, a constructed channel model can be loaded into the wireless monitor, and RF and sound layer parameters 204b can be recorded for external wireless link quality calculation.
[00049] Reference is now made to Figure 3, which illustrates a data analysis system 300 according to an exemplary embodiment. The data analysis system 300 may be an example of the data analysis system 104 of the wireless performance testing system 100 of Figure 1. The data analysis system may generally be configured to receive a collection of data and perform a analysis of the respective data. As shown in Figure 3, the data analysis system 300 may include a data store 302 in which a collection of data can be stored, and a data analyzer 304 for retrieving the data collection to perform one or more analysis of the system. wireless of interest based on the same. This collection may be, for example, the collection of wireless monitor 102, or more particularly, in one example, wireless monitor 200 of Figure 2.
[00050] In one example, wireless displays 102 (eg, wireless displays 200) may be configured to wirelessly transmit their data to data analysis system 300 while onboard the complex system. In another example, wireless monitors can be uninstalled from the complex system and then can transmit their data to the data analysis system wirelessly or by wire. At some point, then, the monitors can be reset and installed on the same or another complex system for renewed operation.
[00051] As indicated above, for example, an analysis performed by the data analyzer 304 may include compilation of temporal RF spectrum mapping and/or wireless system performance within the aircraft fuselage. The one or more analyzes performed by the data analyzer can then be used as a basis for one or more conclusions regarding the wireless system of interest or one or more parameters of the wireless system of interest. These conclusions may further be based on one or more parameters of the complex system (which may at least partially define its configuration), and/or one or more operating conditions of the complex system. For example, analysis may be performed to establish a wireless system configuration of interest that meets or exceeds at least one wireless system design requirement. In this regard, the analysis may include computing whether the configuration or operating conditions of the complex system allow the wireless system of interest to operate at a wireless link quality specified by the design requirement(s). The conclusions, in turn, can lead to one or more decisions regarding the respective wireless system of interest, such as one or more decisions regarding its configuration.
[00052] Any issues with the performance of the wireless system of interest in relation to a particular complex system (e.g. aircraft) and particular installation locations of the wireless monitors (e.g. wireless monitors 102) during the purchase period data can be identified from one or more analyzes performed by the data analyzer 304. For example, performance can be characterized by numerous operating conditions that may or may not be harmful (e.g. temperature, passenger movement, systems interfering , etc.).
[00053] To improve the design and integration of a wireless system of interest as a whole, further testing may be desirable. Data acquisition and analysis can thus be repeated on the same or different aircraft with varying parameters (e.g. internal configurations) so that design and performance curves can be developed to improve and optimize future system installations without thread of interest. This can be beneficial from continuously adding data to the 302 data store for analysis and comparison. In one example, numerous wireless system parameters of interest and/or complex system configurations may differ across a number (e.g., tens, hundreds, etc.) of tests, which may allow the development of one or more rules for reduce, if not minimize or exploit, wireless system parameters of interest or complex system to improve performance.
[00054] Back in Figure 1, one or more wireless displays 102 can be installed on board a complex system in any of a number of different ways. In several examples, wireless monitor(s) can be installed in a non-intrusive configuration where the monitor(s) can be segregated from the wireless system of interest, which can be installed or planned for installation on board the complex system. This configuration may include two or more displays installed onboard the complex system. Depending on the sophistication required, each wireless monitor may include all or only a portion of the functionality shown in Figure 2. Wireless monitors in this configuration may be parasitic, in that they may serve no function other than collecting pertinent data for analysis. the performance of the wireless system of interest.
[00055] In other examples, the wireless monitor(s) 102 can be installed in an intrusive configuration where the wireless monitor(s) can be integrated(s). s) and superimposed(s) to an installed wireless system of interest. In this configuration, the hardware of the wireless system of interest can, in fact, be configured to implement the functionality of one or more wireless displays in addition to the functionality of the wireless system of interest. In many cases, then, this configuration may not require separately installed wireless monitors, or may include additional, separately installed wireless monitor(s). Instead, the wireless system hardware of interest can be configured to operate in multiple modes that include a "monitor mode" where the hardware performs the functionality of one or more wireless monitor(s). This configuration may therefore not be parasitic.
[00056] Exemplary embodiments may first be described in this document in the context of a non-intrusive configuration. It should be understood, however, that principles of the non-intrusive configuration can equally or similarly be applied to the intrusive configuration.
[00057] In the non-intrusive configuration, wireless displays 102 may be installed in one or more locations on board a complex system where a wireless system of interest is installed or planned to be installed. In one example, wireless displays can be installed and arranged aboard the complex system in a way that depends on the type of wireless system of interest and its radio access technology. As explained above, the wireless system of interest can be any of a number of different types such as a WLAN, cellular, RFID, in-flight entertainment, emergency lighting, emerging aircraft health monitoring sensor system or the like, and the A wireless system may include one or more wireless hardware components configured to operate under one or more of a number of different radio access technologies. These wireless hardware components can be configured to communicate with each other, and/or one or more other wireless hardware components external to the wireless system. Wireless displays may therefore be installed at one or more locations on board the complex system where wireless hardware components of the wireless system of interest are installed or planned to be installed, and/or at one or more external wireless hardware components with which wireless system components of interest are configured to communicate.
[00058] Figure 4 is a schematic illustration of an example aircraft 400 that includes a cabin 402 in which a WLAN system is installed or planned to be installed. The WLAN system may include an appropriate wireless access point which can be accessed by one or more compatible wireless devices such as smartphones, tablet computers, laptop computers or the like. These types of devices can be brought on board the aircraft and operated by passengers from different locations inside the cabin while the aircraft is in service. As shown in Figure 4, then, one wireless monitor 404a can be installed in a location above the ceiling where the WLAN access point is installed or planned to be installed, and two other wireless monitors 404b, 404c can be installed in locations where seated passengers can access the respective access point. In this example, each wireless monitor can correspond to a wireless monitor 102 shown in Figure 1.
[00059] In another example, similar to a WLAN system, a cellular system of interest may include numerous wireless devices brought on board the aircraft and operated by passengers from different locations inside the cabin while the aircraft is in service. This type of system may also include a corresponding access point on board the aircraft. Similar to the installation shown in Figure 4, in one example, for a cellular system of interest, a wireless monitor can be installed in an above-ceiling location that can emulate an appropriate access point, and numerous other wireless monitors can be installed. in locations where seated passengers can operate wireless devices. Similar to the above, in this example, each wireless display may correspond to a wireless display 102 shown in Figure 1. In yet another example, an RFID system onboard an aircraft may include RFID tags or readers. in emergency equipment locations (eg, fire extinguishers, oxygen tanks, life jackets, etc.), cargo, electrical equipment platform components, and the like. These identifiers or readers may be configured to communicate with one or more external identifiers and/or readers located throughout the aircraft. Wireless monitors 102 for this type of wireless system of interest can be installed in any one or more of these locations.
[00060] An in-flight entertainment system may include wireless hardware components in various locations throughout the cabin such as above the roof, in the headrests of passenger seats, under passenger seats or the like. Similarly, an emergency lighting system may include wireless hardware components in various locations throughout the cabin such as under passenger seats, by doors, above roof panels or the like. Wireless monitors 102 for these types of wireless systems of interest may be installed in any one or more of these respective locations, and/or any other location of external wireless hardware components with which these types of wireless systems are configured. to carry out the communication.
[00061] An emerging health monitoring sensor system such as an integrated vehicle health management (IVHM) system may include sensors located at various locations throughout the aircraft. In one example, an IVHM system may include temperature sensors (e.g. inside and/or outside the main cabin), strain gauges, tire pressure sensors, brake temperature sensors, smoke/fire detectors or the like. , any one or more of them can be configured to communicate with external wireless hardware components. Wireless monitors 102 for this type of wireless system of interest can be installed in any one or more of these locations.
[00062] After installation, wireless monitors 102 can be enabled to collect data, such as at regular configurable intervals. Wireless monitors can be configured to collect data in a number of different ways. In one example, monitors can be configured to operate in a center-radial arrangement where a designated monitor can be configured to function as a central monitor responsible for interrogating and receiving responses from one or more other monitors configured to function as node monitors. . In this arrangement, node monitors can be configured to communicate with the central monitor, but may not communicate with each other. As shown in Figure 4, for example, wireless monitor 404a can be configured to function as the central monitor, and wireless monitors 404b, 404c can be configured to function as node monitors.
[00063] In one example, wireless monitors 102 in a center-radial arrangement can be configured to perform a connectivity check. The central monitor can be configured to check connectivity from the node monitors to the central monitor at regular intervals. The central monitor can then be configured to record connectivity success or failure for each node monitor with an appropriate timestamp. In this regard, the success or failure of a connectivity check can be determined based on the type of wireless system of interest and its radio access technology. For an RFID system of interest, for example, interrogated node monitors can respond with their respective identifiers (IDs), which the central monitor can collect. For a WLAN system of interest, for example, interrogated node monitors can respond with their respective Internet Protocol (IP) addresses or other parameters, which the central monitor can collect.
[00064] In one example, interrogated node monitors 102 can respond to a query from the central monitor with sample data from which the quality of the communication link between the central monitor and the respective node monitors can also be determined . In this case, the central monitor can be configured to request the sample data as in the connectivity check, and can evaluate the sample data received (or lack thereof) from each node to verify success. In another example, the central monitor can be configured to calculate and record one or more additional communications characteristics over the node monitors.
[00065] In the center-radial arrangement, the data analysis system 104 can perform any of a number of different analyzes of the data collected by the wireless monitors 102. In one example, the data analysis system can be configured to analyze the data. to define where the hard limit of coverage can be from the central monitor location. More particularly, for example, the data analysis system can be configured to determine how many meters away from the hub the system can be expected to operate at a given data rate (e.g. WLAN), how far an RFID tag can be located and still be read, or similar. The analysis can include statistical estimates with probabilities assigned as a function of radius. The natural implications may lie in determining the number of antennas or access points required. If the number of access points or anticipated antennas can be reduced based on the analysis, the complexity and weight of the aircraft can be reduced.
[00066] In another example, the wireless monitors 102 can be configured to operate in a mesh arrangement where central and node monitors can be unrecognizable. Any monitor can be configured to function as a central monitor or node monitor; or in other words, any one or more monitors can be configured to selectively function as a central monitor or node monitor. The mesh arrangement can allow the collection of a larger amount of sample data, as the wireless monitors can communicate with each other rather than a single central monitor, which can allow for multiple coverage estimates.
[00067] As shown in Figure 4, for example, any of the wireless monitors 404a, 404b, 404c can be configured to function as a central monitor or node monitor, or can be configured to selectively function as a central monitor and monitor of node. For a WLAN system of interest, for example, any monitor can function as a central monitor to interrogate other monitors such as nodes to respond with their respective Internet Protocol (IP) addresses or other parameters, which the central monitor can collect. In one example, the central monitor can also be configured to transmit sample data to the central monitors, and create a timestamp and record a successful transmission.
[00068] For an RFID system of interest, for example, each of the numerous wireless displays 102 can be configured to function as a reader or identifier, or selectively function as a reader and identifier, as per the Code standard. of Electronic Product (EPC). In a more particular example, a plurality of monitors can be configured to operate according to a test schedule of one or more cycles where each monitor can be configured to function as a reader during a respective interval (e.g. 20 seconds) .
[00069] In an example for an RFID system of interest, each of a plurality of wireless displays 102 can be assigned to the respective range. During the interval of a monitor, it can act as a reader to interrogate and receive responses from other monitors, which can act as identifiers. Such interrogation of an identifying monitor may include the reading monitor which transmits a query to the identifying monitor. The identifier monitor can create timestamp and record receipt of the survey, and can respond to the survey with its ID. The reader monitor can receive, create timestamp and record responses from the identifier monitors. At the end of the interval, and before or at the beginning of a next interval, the reader monitor may switch to function as an identifier monitor, and an identifier monitor assigned to the next interval may switch to function as the reader monitor. The process may then repeat for the next reader monitor, and may occur for each monitor of the plurality for one cycle. A test schedule can include one or more cycles, and in many cases, it can be over a period of seconds, minutes, hours, days or longer.
[00070] In the example where wireless monitors 102 can cycle between a reader and tags, multiple monitors can be distributed throughout the complex system. In the context of monitors distributed throughout an aircraft cabin, for example, for a reader monitor located at the rear of the cabin, identifier monitors located at the rear of the cabin may be outside the range of the reader monitor. But when the reader function switches to a monitor located in the middle of the cab, the identifying monitors located at the front may begin to respond. In this way, the entire cabin volume can be sampled providing meaningful data, which includes electrical equipment load and platform.
[00071] For a test sequence run over several hours, the data collected by the wireless monitors 102 can provide enough information to statistically quantify the probability of successful communication as a function of distance in the car (an example of a parameter of interest) . Additionally, in cases where the test sequence is performed during a test flight, the performance of the RFID system of interest can be analyzed for changes under normal operating conditions. For example, the data collected can be analyzed to determine whether an RFID reader in the RFID system will operate as well on the flight line (in the presence of many potential sources of interference) as it does in flight in a remote area where no interference is present. is expected.
[00072] While the above example highlights the use of wireless monitors 102 in the context of an RFID system of interest, similar test sequencing and monitoring functions can be adapted for other wireless systems of interest. Displays can be flexible where they can be reconfigured to emulate any of a number of different wireless systems of interest. In some cases, the same can be valuable for understanding the performance impact of multiple radio access technologies with passengers on the move. In such cases, wireless monitors can be installed on board the aircraft in somewhat arbitrary locations, and can be configured to collect data in a way that monitors multiple different systems of interest in the presence of a dynamic environment.
[00073] In other cases, the impact of cabin configuration (e.g. model of passenger accommodations, interiors, seating, etc.) on one or more wireless systems of interest may trigger the installation and operation of wireless displays 102 to collect data. In such cases, monitors can be configured to collect data only for the radio access technologies of the wireless systems of interest. In still other cases, interference may be a focus, and it may be desirable to have the displays split function across multiple wireless systems of interest, and simultaneously operated to collect data. For example, using the flexible and reconfigurable nature of the monitor, its operation can be configured to collect data for analysis of the impact of different wireless systems operating in the presence of each other on a shared spectrum. In this case, displays in the main cabin can be configured to employ MIMO technology for an in-flight entertainment system of planned interest, while other displays on the cargo platform can be configured to communicate via Zigbee, Bluetooth or the like for an in-flight entertainment system. emerging health monitoring sensor of planned interest.
[00074] In one example, in order to quantify the differences between large and small cabins, a test can be performed with standard 102 wireless monitors on board an aircraft. In that case, a central monitor can be installed in front of the main cabin above a roof panel, and a node monitor can be installed in the middle of the cabin under a seat. In this test, monitors can be installed and data collected for numerous single-aisle and dual-aisle aircraft (parameters of different configurations). The data can be passed to the data analysis system 104, which can filter and prepare the data in time so that the operating conditions of the aircraft (e.g., in flight with passengers generally free to move) can be the same as on the aircraft. . Figure 5 illustrates a graph that provides a theoretical comparison of three aircraft of each configuration. The vertical geometry axis shows energy, but should instead show any of a number of other parameters like BER, SNR, data rate, or the like. These settings may have been set prior to testing and may have guided the data collected through the wireless monitors.
[00075] The results shown in Figure 5 indicate that the wireless system of interest onboard each aircraft may function differently due to any number of factors (e.g. indoor model), but on average, the aisle configuration single can provide higher power levels than dual aisle configuration. If the wireless system of interest aboard a 787 aircraft was replicated on a smaller platform like the 737 aircraft, these results show that it can work.
[00076] In another example, considering a new wireless system such as an in-flight entertainment system, it must be installed in a cabin that already has another wireless system such as an emergency lighting system installed. A test can be joined to assess the potential for interference. Figure 6 illustrates a graph resulting from the analysis of data collected during testing. The curve shows the BER for two wireless displays 102 installed in an emergency lighting operating mode (eg 2.4GHz, Zigbee radios) to emulate the emergency lighting system. These displays can more particularly emulate, for example, a suspended receiver (eg output signal) and a controller mounted under the seat of the emergency lighting system. The vertical geometry axis shows the BER emitted from the receiver during a test for a single aircraft. Subthreshold performance is expected. As shown, prototypes 1, 2 and 3 represent different configurations of the new in-flight entertainment system. The results indicate that prototype 1 introduces unacceptable interference, prototype 2 is marginally compatible, and prototype 3 is completely compatible. Much larger sample sets may be desired to make appropriate engineering decisions on which prototype is best or whether others should be explored.
[00077] In yet another example, the impact of different aircraft interiors can be assessed. Like using two wireless monitors 102 as a central monitor and node monitor, for example, the focus can be on the ceiling and changing storage compartments. The central monitor can be installed above the ceiling panel in the same relative location on each aircraft tested. The node monitor can be arbitrarily installed in a fixed location on the other side of the ceiling panel, and its relative location can be fixed for each aircraft test. As shown in the graph of Figure 7, two large sample sets can be obtained. The first sample set can be multi-test in the original ceiling panel configuration, and the second set can be multi-test in the new ceiling panel/storage compartment configuration. When comparing the two sample sets, it can be seen that the new type of ceiling/storage compartment has no appreciable performance impact. The vertical geometry axis can be any measurable parameter enabled by the wireless displays. The measured parameters can be defined at the beginning of the test, and can guide the data collection by the monitors.
[00078] In yet another example, the impact of different aircraft interiors can be assessed. With the use of two wireless monitors 102 as a central monitor and node monitor, for example, the focus can be on the ceiling and changing storage compartments. The central monitor can be installed above the ceiling panel in the same relative location on each aircraft tested. The node monitor can be arbitrarily installed in a fixed location on the other side of the ceiling panel, and its relative location can be fixed for each aircraft test. As shown in the graph of Figure 7, two large sample sets can be obtained. The first sample set can be multi-test in the original ceiling panel configuration, and the second set can be multi-test in the new ceiling panel/storage compartment configuration. By comparing the two sets of samples, it can be seen that the new type of ceiling/storage compartment has no appreciable performance impact. The vertical geometry axis can be any measurable parameter enabled by wireless displays. The measured parameters can be defined at the beginning of the test, and can guide the data collection by the monitors. In one example, the parameter might be power, and the graph might show performance above a threshold. Analysis of a different parameter such as fading depth, however, may describe that the threshold may not be met for a specific wireless system of interest and radio access technology.
