| Multi-system distributed coverage system has to meet different demands simultaneously:signal strength, capacity, frequency interference,inter-system cooperation, operation stability, etc, to sustain high quality, smooth and stable services.This paper is based on Campbell model, TD-SCDMA system theory, GSM system theory, WLAN system theory, etc. The structure of this paper consists of parts like TD-SCDMA/GSM/WLAN. The paper discusses the detail system design and the system realization, including coverage design, capacity design, inter-system cooperation design and system failure redundancy consideration. |
