李俊杰, 卢卓君, 薛嵬峰, et al. Coverage analysis and building guideline for WLAN and multi-system combine[J]. 2011, 24(4): 7-12. DOI: 10.13992/j.cnki.tetas.2011.04.018.
with the quick development of mobile communication
China Mobile had developed from the single GSM business to be the multi-system network operator covered GSM+TD-SCDMA and WLAN business.Not only the large scale indoor distribution system for GSM had been built up
but also the distribution system of GSM+TD-SCDMA combined by building and rebuilding during the 3G construction period.The build mode of WLAN deployment was multi-system combining directly which had the advantage of simple and quick build
investment saving.But the low output power in AP
high loss on 2.4GHz and strict coverage requirement cause the simple direct combine can’t satisfy the requirement of network building.Thus
the different analysis and deep research was urgent for the WLAN and multi-system combine scenario.
