Indoor micro cell area prediction system using ray-tracing for mobile communication systems

In mobile communication systems, especially digital wireless PBX systems, it is very important to clarify the service area in case of indoor base stations. However it is very difficult to estimate the propagation characteristics accurately under these environments because the indoor components, ex. wall partition, etc., are not only positioned randomly, but also made from complex materials. An indoor micro cell area prediction system, which can be easily estimate the propagation characteristics using the ray-tracing method, is proposed and its system configuration and major performance are described.
