Research On Wireless Local Telephone Network Optimization For PHS

PHS belongs to mobile communication system. Firstly, the thesis analyze its principle and know something about the structure.The thesis mainly researched the Wireless local telephone Network optimization for PHS. The prediction of the propagation of electromagnetic wave is most important in urban areas where subscriber density is high, and the buildings have a profound influence on the propagation. Base on theory about the propagation of PHS wireless network electromagnetic wave and the characteristic of PHS, we found a propagation model to analyze the path loss and an arithmetic based on the adaptive coefficient in this thesis. The new algorithm is based on self-adaptation theory which improves calculation precision of the propagation prediction. This gives the theoretical foundation for the optimization of the PHS wireless network.This thesis proposed the wireless public opinion network optimized solution method to solve the disturbance in PHS network such as network cover, CS synchronization, CS disturbance and Paging Area division and so on. At the end of this dissertation, we give the actually typical cases of the wireless network optimization with the models and methods given in this dissertation.
