4/5 G high-performance multimode baseband processing unit supports all-operator, full-band, whole-system, total station common frame and multiple networking deployment mode. The product is simple and aesthetic, with a strong sense of technology, economical and energy-saving, convenient to maintain, and conducive to deployment. The high reliability is achieved by optimizing the air duct design and the heat dissipation effect of the hoist frame. Based on the sleep technology for load adjustment software and hardware, continuous consumption reduction is realized, and investment and operating costs can be saved for customers. In the 5G C-RAN scenario, the integration level is higher and the extendibility is stronger, which is conducive to centralized deployment.
