Digital Fiber DAS Application Case-160,000Sqm Coverage

The overall coverage of the Golden Waterfront Urban Community (China Telecom CDMA + LTE + Unicom WCDMA + LTE Cellular Signal )

Golden Waterfront is a commercial and residential community is a building area of 150,000 square meters. After testing, indoor China Telecom and Unicom wireless signals have extremely poor coverage, and indoor distribution systems need to be introduced. Considering that the operators of this site, Telecom and China Unicom, both have wireless network coverage requirements, and the traditional coincident coverage cost is too high, and the construction period is long, this site introduces China Unicom’s Fiber DAS, while solving telecommunications CDMA + LTE and China Unicom WCDMA + LTE coverage, and there is no interference between the signals of the two operators. On the premise that the coverage meets the requirements, the overall construction cost has been saved by 30%, and both operators are very satisfied.
