A Wireless Network for Wideband Indoor Communications.

We propose and analyze a wideband indoor communication system that uses radio as the transmission medium either on a stand- alone basis or to supplement a hard-wired network for those situations where complete portability is desired. The principal impairments to such a system are intersymbol interference caused by frequency selective fading and shadow fading caused by path blockage. A novel media access scheme is proposed which permits the use of resource sharing, wherein a small pool to time slots is effectively shared among all users to provide added protection against channel impairments on an as-needed basis. Our results show that the use of resource sharing and diversity provide excellent protection against the dominant impairments with negligible impact on throughput.
