Abstract:
1. A system for dynamically assigning wireless channels in a wireless network, the system comprising: a first client device having a transceiver to transceive wireless data, the first client device being associated with the wireless network and assigned to a wireless channel; and a second client device having a transceiver to transceive wireless data, the second client to associate with the wireless network by requesting assignment of a wireless channel, wherein if the first and second client devices receive data at substantially different data rates, the first and second client devices are assigned to different wireless channels, whereas, if the first and second client devices receive data at substantially similar data rates, the first and second client devices are assigned to a common wireless channel, in order to optimize total system utility of the wireless network; wherein the first and second client devices transceive data on a common wireless channel based upon a power level selected to maximize data rate transfer in view of power level requirements for the wireless network and wherein, in order to select the power level to maximize data rate transfer between the first and second client devices, data rates at which the first and second client device receive data at are estimated at a plurality of different transmit power levels.
