Abstract

To enhance the frequency-utilization efficiency, cellular mobile radio systems widely use a sector cell structure for the base stations. The conceptual design formula previously reported are extended for frequency double reuse indoor picocellular systems. A three sector cell structure is adopted for the urban cellular base stations and omni-directional base stations are used for the indoor system, which is in the final stage of implementation. In particular, the small cluster size case is analyzed for TDMA cellular systems
