With a focus on customer-oriented innovation, Huawei has launched a series of products in its SingleRAN product portfolio, including the distributed E-UTRAN NodeB (eNodeB) DBS3900 DSA. E-UTRAN is short for evolved universal terrestrial radio access network. The DBS3900 DSA fully utilizes Huawei platform resources and a variety of technologies to meet the challenges of smart union network development.

The eNodeB is used for radio access in the DSA system. The eNodeB mainly performs Radio Resource Management (RRM) functions such as air interface management, access control, and User Equipment (UE) resource allocation.

The DBS3900 DSA has two types of basic modules: Baseband Unit (BBU) and Remote Radio Unit (RRU). The basic module with small size and light weight features can be flexibly installed to accommodate varied site environment. It also supports flexible software configuration to meet different capacity requirements.

The DBS3900 DSA supports 230M/400M narrow-band discrete frequency. The RRU has the advantages of various working bandwidths, large transmit power, and high power amplification efficiency.
