The traditional way to allocate the frequencies to new cells of in-service GSM network is always manually. The shortcoming is time-consuming, and the veracity is not satisfied. This paper presents an innovative algorithm of fully automatic frequency planning for the new cells. The proposal uses the triangulation principle to stratify the cell sites in GIS map to confirm the list of neighbor cells,...
Cell coverage analysis is an important task of mobile network optimization, but there is dearly insufficient in the accuracy, validity and visualization in current analytical methods and tools. This paper presents a multi-factor analysis method of cell coverage, and realizes the relevant system based on GIS platform. Based on a huge number of mobile measured data, this method derives a cell coverage...
