Baseband Processing Unit (BBU) Core of Mobile Communication Base Stations

When using the Centralized BBU deployment model, a number of base station BBU functions are housed within a single physical location. This increases management convenience since BBUs can be serviced from a single control point, thus, enabling remote monitoring. Multiple base stations can be combined into a single operational unit which improves resource allocation. However, geo-distributed RRU's require high capacity backhaul links for connection. Where base stations are located in close proximity to each other, this model improves network functionality, but the backhaul network must be meticulously planned to eliminate potential traffic slowdowns.
