    摘要: In a peer-to-peer wireless communication network, a first device listens during an advertise state for polling signals from second devices on a first channel included in a plurality of channels. During the advertise state a response to a first polling signal transmitted by one of the second devices on the first channel is transmitted from the first device, if the first polling signal is received on the first channel during the advertise state. A second channel is selected at the first device from the plurality of channels for use during a search state of the first device. A second polling signal is transmitted with the first device, on the selected second channel during the search state. The first device listens during the search state for polling response signals on the selected second channel, the polling response signals responsive to the second polling signal.

    摘要: A network interface comprises a random or pseudo-random number generator. The network interface determines that a first communication device is group owner of a peer-to-peer (P2P) group, and randomly or pseudo-randomly generates a media access control (MAC) address for the first communication device using the random or pseudo-random number generator. The network interface utilizes the randomly or pseudo-randomly generated MAC address for the first communication device in group owner communications with one or more second communication devices in the P2P group.

    摘要: A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.
