A three ray propagation model for PCS and micro-cellular services

This paper presents a three ray propagation model for PCS and /spl mu/-cellular services. The salient concept of the proposed model is to maintain cell radii within the Fresnel zone break point. In this region, the path loss slope is similar to free space loss, irrespective of the propagation medium. This analogy is then used to predict cell radii for indoor and outdoor deployment of PCS; requiring virtually no computer aided prediction tools. It is further shown that the ceiling height plays an important role in antenna placement. The proposed method is appropriate for low power PCS and micro-cellular services, offering a greatly simplified and cost-effective deployment process.
