Cell Capacity for IEEE 802.16 Coverage Extension

This paper analyzes a two-hop extension to the coverage of an IEEE 802.16 cell. There is natural degradation in cell capacity due to multihop communications which can be mitigated by spatial reuse, adaptive modulation and coding. We estimate the available capacity by analyzing the random geometry related to the locations of the base station, the sponsor nodes and the mesh subscriber stations situated two hops away from the base station. The results show the trade-offs of extending the coverage area and the decrease of the capacity.
