Abstract :
Broadband wireless access systems are members of a large class of shared medium access systems where a single central site communicates with multiple subscriber stations over a single transmission medium. This article introduces a novel method of sharing the single transmission medium with a number of subscriber stations in fixed BWA systems, which supports integrated voice/data transport and dynamic bandwidth allocation. A MAC implementation in 3.5 GHz fixed BWA system is given, which focuses on the dynamic access technology of voice. FDD/TDM/TDMA mode is applied in the system. In the end of this article, block diagrams describing how voice access PSTN through E1 interface are given.
