ABSTRACT:
The present invention is related to a switch for use in wireless communication systems. In one embodiment, the switch can concurrently process data from multiple mobile stations and supports full duplex, i.e., allowing receiving and transmitting data at the same time. The switch can concurrently communicate with other switches and/or mobile stations in the basic service set (BSS) of that switch. A switch may be considered an access point commonly used in other approaches. However, systems using the switch do not need to use an Ethernet switch commonly found in WLAN communication systems that use access points. Switches may be set up in a master-slave scheme wherein a master switch communicates with its slave switches, and slave switches communicate with one another through the master switch. If the data is for a mobile station in the same BSS of the switch, then, via a switch controller, the switch passes the data from the receiving path to the transmitting path. As a result, the data does not have to travel out of the switch and then back to the same switch again.
