This paper presents research status on public broadband wireless communication (PBB) system. The PBB system uses VHF band between 170 MHz and 205 MHz that is available after termination of analogue TV broadcasting service on July 24, 2011. This paper summarizes the transition of television service from analogue to digital and fundamental specification on spectrum usage, physical and MAC layers.
IEEE 802.16 provides wireless broadband access approaches with support for both single-hop and multi-hop mesh modes. It defines several traffic and service categories and offers differentiated quality of service (QoS) for them through scheduling algorithms. In IEEE 802.16, a three-way handshaking mechanism is given to reserve the slots hop-by-hop for mesh networks, which is called hop-by-hop Bandwidth...
