HUAWEI BBU3900 PDF

Networking Application Simple Structure and Fast Network Deployment The DBS has only two types of basic functional modules, thus greatly reducing the investment in spare parts and maintenance. With excellent environment adaptability, basic modules can be easily adapted to onsite conditions to achieve efficient deployment, obviating an equipment room. That is, there is no additional cost of construction an equipment room. Flexible Installation and Particularly Well-Suited to Railway Coverage The remote radio module provides the following benefits: Since the RF module of the DBS can be mounted on top of the tower, the feeder length is significantly reduced and the cost of procuring feeders is decreased accordingly. Thanks to the radio remote technology, the DBS supports distributed installation of baseband and RF modules, which provides great flexibility to design the coverage along railway lines.
