Patent ID: 8730841

Claim:
A method of operating a peer to peer communications device to use both a wide area network uplink communications band and a wide area network down link communications band, the method comprising: during an uplink share mode of operation, during which said wide area network uplink communications band is used for peer to peer communications between peer to peer communications devices, implementing a first transmission power control function used to control the transmission power of peer to peer signals transmitted by said peer to peer communications device; and during a downlink share mode of operation, during which said wide area network downlink communications band is used for peer to peer communications between peer to peer communications devices, implementing a second transmission power control function used to control the transmission power of peer to peer signals transmitted by said peer to peer communications device, said second transmission power control function being different from said first transmission power control function, said second power control function using a lower maximum transmission power level than said first transmission power control function.
