DUAL MODE SUBSCRIBER UNIT FOR HIGH SPEED, SHORT REACH AND LOWER SPEED DATA COMMUNICATIONS, LONG REACH.

摘要

A subscriber unit comprising: a first transceiver (140) configured to communicate with a cellular network through a cellular layer communication protocol; a second transceiver (240) configured to communicate with a wireless local area network, WLAN, through a layer IEEE 802 communication protocol; a detection circuit (201) configured to detect a signal from the WLAN; a circuit (120, 211A, 211B) coupled with the first transceiver (140) and the second transceiver (240) and which is configured to communicate using the second transceiver (240) in response to the signal, characterized in that the cellular communication protocol Layer includes a plurality of layers above a physical level and a plurality of physical layer channels available for assignment of communication with the cellular network; and a first converter (130, 132, 134) is configured to maintain a communication session above the physical layer when the assigned physical layer channels have been deallocated
