摘要： A channel management system in a wireless network includes a master radio and a surrogate radio. The master radio performs data communication with one or more clients on a first channel in the wireless network, and the surrogate radio simultaneously scans other channels in the wireless network. A channel manager determines if a channel switch is needed, and the data communication is switched to a second channel based on the scanning of the other channels.

摘要： In a network, a first network station (61) communicates with a second network station (65) using a first channel (45) from a plurality of channels. The first channel (45) has a central frequency (46). A third network station (62) communicates using a sub-channel (55) of the first channel (45). The sub-channel overlaps the first channel (45). The sub-channel (55) has a center frequency (56) that varies sufficiently from the center frequency (46) of the first channel (45) so that the first network station (61) and the second network station (65) do not lock onto packets transmitted from the third network station (62). The center frequency (56) of the sub-channel (55) is closer in frequency to the center frequency (46) of the first channel (45) than to a center frequency of any other channel in the plurality of channels.

摘要： In an example, packets transmitted over a communication channel from a transmitter are received. Channel state information (CSI) from the received packets are obtained and signal-to-noise (SNR) values of the communication channel are computed based on the obtained CSI. In addition, effective bit error rate (BER) values are determined based on the SNR values, a coherence time period within which the effective BER values of the communication channel remain within a predetermined range is determined, a modulation and coding scheme (MCS) to be implemented by the transmitter is determined based on the effective BER values within the coherence time period, and the determined MCS is transmitted to the transmitter.
