ZTE new generation BBUs work in 2G/3G/4G/5G multi-modes. The BBUs support abundant interfaces, flexible networking, and smooth evolution and achieve more flexible capacity configuration with the industry's only full-mode baseband board. The BBUs can provide indoor and outdoor models to meet the requirements of customers for multi-scenario low-TCO network construction and provide high-quality 5G services. By inserting a high-performance board, the indoor BBU can support the NodeEngine solution and help the customer to quickly construct a smart and simple local private network. In 2022, a new series of boards based on new-generation chipsets are released to significantly enhance the NR and multi-mode capacity and greatly reduce the power consumption. Fewer boards configuration will satisfy more complicated multi-mode site requirements.
