A three ray propagation model for line of sight PCS and μ-cellular services

This paper presents three ray propagation model for line of sight (LOS) PCS and μ-cellular services. The proposed model is based on Fresnel zone break point where the path loss slope is similar to the free space loss. This analogy is then used to predict the 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 determining the optimum location of the antenna. The proposed method is appropriate for low power PCS and micro-cellular services, offering a greatly simplified and cost-effective deployment process
