The processing continues by receiving an RF signal containing a preamble of a frame via one of the plurality of channels. The processing continues by converting the RF signal to a baseband signal based on the initial setting. The processing continues by determining channel type of the one of the plurality of channels based on the baseband signal. The processing continues by determining whether the channel type corresponds to the bandwidth of the initial setting. The processing continues by, when the channel type does not correspond to the bandwidth of the initial setting, adjusting setting of the RF receiver based on the channel type.

The method continues by, when at least one of the target stations has a different protocol than the protocol of the source station, determining whether the wireless communication is a direct wireless communication or an indirect wireless communication. The method continues with the source station transmitting a frame to an access point, wherein the frame is formatted in accordance with the protocol of the source station, when the wireless communication is the indirect wireless communication. The method continues with the access point converting the frame into at least one alternate frame based on the protocol of the at least one of the target stations having the different protocol. The method continues with the access point transmitting the at least one alternate frame to the at least one of the target stations.

    摘要: A single chip radio transceiver includes circuitry that enables detection of radar signals to enable the radio transceiver to halt communications in overlapping communication bands to avoid interference with the radar transmitting the radar pulses. One design goal, however, is to avoid false triggers that result from spurious tones and omissions and that further detects radar signals even in circumstances in which a radar pulse has been masked or eliminated by interference. Accordingly, the radar detection block includes circuitry for detecting and measuring the radar signals in the presence of such interference. More specifically, the radar detection block includes a moving average filter, a threshold comparison state machine, and radar detection logic within software that is executed by a processor for determining whether a radar signal is present.
