Huawei WD22LBBPC BBU3900 / BBU3910 / BBU5900 (HERT BBU) Base Station Module

The Huawei WD22LBBPC (LBBPc) is an LTE baseband processing unit card used in the Huawei HERT BBU platform, deployed across the BBU3900, BBU3910 and BBU5900 distributed base station chassis. It handles LTE uplink and downlink baseband signal processing for the base station, forming part of Huawei’s modular LBBP family of LTE baseband boards (which also includes LBBPd1 through d5 and related variants) that let operators scale LTE baseband capacity within a shared BBU chassis according to site traffic requirements. The HERT BBU software platform, which Huawei has had formally security-evaluated under Common Criteria, underpins the control and management software running on these baseband cards, and the LBBPc board fits the same backplane slot architecture used across the wider BBU3900/3910/5900 family, working alongside the platform’s transmission, power and interface boards. Because BBU3900/3910/5900 baseband cards were deployed at very large scale for global LTE rollouts, tested secondary-market LBBPc boards remain a common field spare. Tech-Star (UK-based, shipped worldwide) stocks tested Huawei baseband spares; enquire for current stock and compatibility confirmation.
