A wireless access point includes an ability to transmit signals over a plurality of channels and receive signals over the plurality of channels and have means for synchronizing transmission on a first channel to a first station and transmission on a second channel to a second station, such that acknowledgements are not expected from one of the first and second stations while transmitting frames to one or more of the first and second stations, means for transmitting over at least two of the plurality of channels simultaneously, means for receiving over at least two of the plurality of channels simultaneously. The number of channels might differ from implementation to implementation, but allows for simultaneous communication over the multiple channels with synchronization such that transmission on a channel is done while not expecting acknowledgements on any of the other channels. Synchronization can be done by ending transmission on a first channel and a second channel at the same time or within a predetermined short time period and/or organizing frames to be of similar size and beginning transmission at approximately the same time, so that transmissions end at the same time or within a predetermined short time period. Organizing frames to be of similar size can be done by breaking up packets as needed to get similar sized frames, using an 802.11 fragmentation facility, padding short packets as needed to get similar sized frames, and/or other methods. The access point might use NAV intervals and CTS-to-self signals to clear channels. |
