    HISTORY OF THE INVENTION
    [0001] Wireless Local Area Network (WLAN) and Wireless Personal Area Network (WPAN) devices that use different radios are widely used in various platforms such as notebooks, net-books, desktop computers, cell phones, personal devices furniture and the like. WLAN and WPAN devices may include, for example, WLAN and Bluetooth (BT) transceivers that operate according to IEEE 802.11 standards. WLAN devices and transceivers are referred to herein as WiFi transceivers and/or WiFi devices. WiFi and BT transceivers can operate in the same frequency band, for example the 2.4 GHz frequency band, or in different frequency bands , for example, the BT transceiver can operate in the 2.4GHz band and the WiFi transceiver can operate in the 5GHz frequency band.
    [0002] Another frequency band that WLAN and WPAN devices can use is the 60 GHz frequency band.
