Abstract :
New interactive multimedia services have increased the urgent requirement for more bandwidth and turn broadband wireless technology as one of the most competitive solutions for the last mile problem. This paper presents an adaptive transport protocol design and evaluation for a multicarrier point-to-multipoint outdoor broadband wireless access system, in the 5.8 GHz and 10.5 GHz frequency bands. With minimal overhead, the protocol is able to support multiple terminals and services that range from video broadcasting to full symmetric traffic. Moreover, adaptive modulation and coding schemes can be applied per terminal per time frame, in either the downlink or the uplink direction. In the proposed system various innovative techniques are used for efficient utilization of the available bandwidth. Finally, the protocol gain is evaluated.
