Efficient use of space, spectrum and time in radio LAN

The context is the design of radio systems for widespread use in workplaces and public areas with service capacities that are a substantial fraction of that provided with wires. The capacity must be both for high peak-to-average LAN data traffic and bandwidth-on-demand virtual connection. The access method plays a part in determining the efficiency and capacity of a radio system, as do radio modulation and available bandwidth. Some of the most important factors that enable maximization of total communication capacity within a given geographic area of spectrum bandwidth are summarized. Continuous coverage radio system design is discussed within the context of the reuse factor, the distance factor, and the capacity. The advantage of access points is considered. Radio modulation is outlined. The characteristics of a time efficient access method are described. Multiplexing of connections and the LAN is considered
