Development of a Digital Cellular System Based on the Japanese Standardibed. The digital system offers high quality facsimile/data as well as the conventional voice service. Compact and long battery life, portable digital telephones will be introduced. System capacity can be increased by using diversity, microcells, low-bit-rate speech coding, and new frequency (800/15

On the Capacity of Time-Space Switched Cellular Radio Link Systems for Metropolitan Area Networksd data traffic. In the paper a novel architecture for a fixed cellular radio system is proposed. The proposed system uses electronically steerable antennas to combine time and “space” multiplexing. Assuming a high user-density urban environment, the performance of the system is estimated for some si

Teletraffic Models for Urban and Suburban Microcells: Cell Sizes and Handoff Ratesr cellular system layout and planning and to evaluate tradeoffs in system design issues. In this paper, we begin with a study of handoff rates in evolving cellular systems. Using simple geometry, we show that in macrocells with homogeneous traffic the handoff rate per call increases only as the squa
