To fulfill our company's promise of long term growth for customers, Huawei is committed to leadership in across-the-board development of LTE. Huawei firmly believes LTE to be critical to global introduction of mobile broadband services. Over the coming year, we will maintain our existing level of investment across GSM, UMTS, CDMA and TD-SCDMA while dedicating added resources to further drive LTE.
As the originator and earliest pioneer of distributed base stations, Huawei's leadership is consolidated with presentation of the DBS3900 LTE. The DBS3900 LTE consists of two parts: the BBU3900 and the RRU3201; the RRU3201 can be installed next to antenna and connected with the BBU3900 via optical cables to minimize RF feeder loss. With the same power and system capacity, a lower RF feeder loss supports wider system coverage or a smaller quantity of sites for fixed coverage. Expanded coverage capability, easier site acquisition and dramatically simplified installation deliver remarkable TCO savings for operators worldwide.
