Huawei Base Station 3703

HUAWEI TECHNOLOGIES CO., LTD.

Huawei WiMAX Base Station 3703 The Huawei BTS3703, a WiMAX base station, based on IEEE 802.16e-2005 and WiMAX Forum NWG Release 1.0. The BTS3703, networking with WASN9970 and Mobile Station, is widely applied to the wireless broadband services in both fixed and mobile broadband access.

De si gne d in a us er-or ie nte d an d modular manner, the BTS3703 is also a highly integrated, small-sized and light-weighted, catering to operators’ requirements for wide coverage, large capacity, easy installation and maintenance.
