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

This model emphasizes the active BBU deployment architecture where several BBUs are consolidated in a particular central region. It has several core advantages as it improves site and network management since one can control and monitor all the BBUs in one location. It also reduces overall expenditure by eliminating the need for periphery equipment at every base station site, thus lowering operational costs. Also, centralized deployment enhances resource distribution among various cells. This model has its challenges, however. It does require high-capacity backhaul links to connect the centralized BBUs to the distributed RRUs. Despite this challenge, the predominant use of modern high speed fiber optic networks provides a more supportive dominatian of these models in current communication frameworks.
