Propagation measurements and modeling in Jinan city

Propagation characteristics of radio signal in UHF band places fundamental limitations on actual cellular and microcellular system design. The downlink and uplink radio signals are very important for service quality, so accurate prediction of signal characteristics for high grade of service (GOS) in urban areas where subscribers´ density is high is required for better performance of cellular mobile systems. In this paper, we present some competing models in cellular/microcellular system design. The effects of terrain on predicted 900 MHz signals are analyzed. Results of radio signal propagation measurements for Jinan city, China, are compared to those predicted based on Hata-urban (1980), Bertoni-Walfish (1988), Egli, plane earth models
