Patent ID: 8520586

Claim:
A method comprising: receiving, at a first wireless network device of a first system, a first RF signal comprising an inquiry message from an inquiring wireless network device of a remote system; detecting that a second wireless network device of the first system is in an active state; determining a signal strength of the first RF signal comprising the inquiry message; determining a communication frequency associated with the first wireless network device, a communication frequency associated with the second wireless network device, and a communication frequency separation between the first wireless network device and the second wireless network device; determining, at the first wireless network device, a transmit power for transmitting a response to the inquiry message based, at least in part, on the communication frequency separation between the first wireless network device and the second wireless network device, and a signal strength of one or more RF signals received at the second wireless network device; comparing the transmit power associated with the response to the inquiry message to a minimum transmit power for transmitting the response to the inquiry message to the inquiring wireless network device, wherein the minimum transmit power is determined based, at least in part, on the signal strength of the first RF signal, wherein the minimum transmit power represents a minimum power at which the inquiring wireless network device can receive the response without impairments; and transmitting, to the inquiring wireless network device, the response to the inquiry message based, at least in part, on said comparing the transmit power associated with the response to the inquiry message to the minimum transmit power for transmitting the response to the inquiry message.
