Abstract :
The mobile radio channel in areas dominated by hills and mountains is frequency selective with severe time delay spread-up to 40-100 μs is measured in Norway. A GSM mobile can utilize only 15 μs of this channel, while the power laying outside this time window will be received as interfering noise. First order reflection calculations based on bistatic radar theory makes it possible to predict the channel response throughout base station coverage areas, such that the areas with low signal-to-interference ratio can be detected. The method is successfully implemented and verified against measurements
