<p>A WiMAX based system having a base station which communicates to a plurality of consumer premises equipment (CPE) is disclosed. The base station obtains and stores information corresponding to the MAC addresses of each of the CPEs. Messages from one CPE can be sent to the base station and then sent to another CPE using the MAC address stored in the base station. Each CPE may originate an uplink multicast message for transmission to more than one CPEs. When the base station receives the uplink multicast message, the base station broadcasts the multicast message to all of the CPEs identified in the multicast message including the originating CPE. When the originating CPE recognizes the multicast message as a message it originated, the originating CPE drops the multicast message. The CPEs may be grouped into virtual local area networks (VLANs) using group identifiers which permit multicast messages to be transmitted to specific groups of CPEs. Electronic devices having MAC addresses may be connected to each CPE and different electronic devices connected to the same CPE may be part of different VLANs.</p> |
