MOBILE DEVICE WITH INTEGRATED DUPLEX RADIO CAPABILITIES

摘要

Wireless-conferencing radios communicate directly with each other without a bases station using a multiple access protocol, such as Time Division Multiple Access (TDMA). Wireless-conferencing radios can be formed into groups and larger mesh networks. Some groups of wireless-conferencing radios use frequencies in a cellular band to communicate.

主权项

1. A communication system for establishing direct full-duplex communications over a cellular frequency band, the communication system comprising:
a first radio; and a second radio, wherein:
the first radio and the second radio are configured to transmit and receive directly with each other; andthe second radio is configured to:
transmit, to a cellular base station, a request to reserve a sub band of the cellular frequency;receive a response to the request indicating that the sub-band has been reserved;transmitting to the first radio a reference to the sub band; andtransmit and receive directly with the first radio on the sub band.
