Abstract: The present invention provides a method for managing multicast network traffic over a Virtual Local Area Network (VLAN) tunneled between multi-hop wireless networks. The method verifies (506) an address of the multicast packet against a Multicast Admission Table (MAT) of the Multicast Admission Module (MAM) to determine a subscription status of the address of the multicast packet. Based on the subscription status, the method allows (512) transmissions of the multicast packet to travel through the VLAN tunnel session; and denies (514) the multicast packet to travel through the VLAN tunnel session if there is no subscription to the address of the multicast packet. A system thereof is also provided. Figure 5

Abstract: A method of producing signals to emulate TETRA direct mode physical layer to a broadband network, particularly WiMAX network is disclosed. Frames of broadband signals are arranged as a time slot to form a direct mode multiframe, said multiframe is made up of 18 direct mode frames according to TETRA direct mode specification. Two time slots are provided for a call transaction, a first and third time slot within a direct mode frame, for every communication channel. A proper modulation is later assigned for each direct mode burst including linearization burst, synchronization burst and normal burst. The preamble of direct mode burst shall be different from the one used for WiMAX.

Abstract: A wireless access device (100), system (200) and method for routing multicast traffic for nodes between a first network and a second network have been disclosed. The wireless access device (100) comprises a backhaul module (10) for receiving packets from the first network and a multicast module (40) for checking the multicast translation table (90) and converting the multicast packets to a Multimedia Access Control (MAC) layer unicast packet. The multicast module (40) is further adapted for forwarding the MAC layer unicast packets to the access module (70) through the second bridge module (60). The access module (70) is adapted for forwarding the MAC layer unicast packets to subscribed nodes on the second network.
