The Huawei DBS5900 is a high-performance, distributed base station designed specifically for eLTE (enterprise LTE) and private wireless network deployments. It extends the capabilities of previous platforms by offering a modular architecture combining a baseband unit (BBU5900) with remote unit modules (e.g. RRU5904, pRRU/RRH), linked via CPRI or Ethernet over fiber. This enables flexible installation in varied environments—indoor, outdoor, industrial, or enterprise campuses.
Engineered for modern private mobile applications, the DBS5900 supports intelligent access control, radio resource management, mobility features, multimedia services, and mission-critical reliability. It is optimized for LTE and can support converged technology scenarios in localized, private, or campus networks where performance, low latency, and reliability are essential.
Carritech supports operators deploying DBS5900 systems by sourcing and supplying BBUs, remote radios, power supplies, and accessories from trusted global suppliers. Each item is quality-tested to ensure compatibility, helping maintain operational integrity for private LTE deployments.
