Study on 3G network indoor coverage system based on the GSM system

摘要

This paper gives the reason for introducing indoor coverage and discusses the principles and composition of indoor coverage. 3G and GSM shared indoor distribution system is analyzed and a design scheme of 3G network indoor coverage system based on the GSM system has been proposed and scheme model has been selected. Edge field strength and minimum indoor coverage field strength have been studied and calculated that reached the indoor signal coverage requirement. The future of the indoor coverage will be a comprehensive solution with multi-frequency band, multi-service. It will have even higher requirements for the system design.
