A method for receiving high data rate wireless communication transmissions begins by receiving a plurality of radio frequency (RF) signals in accordance with a wireless communication standardized data rate on a plurality of RF channels. The method continues by converting each of the plurality of RF signals into a plurality of signals. The method continues by processing the plurality of signals at baseband or near baseband into media access control (MAC) data, wherein a number of the plurality of signals corresponds to an integer multiple. The method continues by processing the MAC data at a combination of wireless communication standardized data rates to produce recovered data.
