Cellular Network Infrastructure: From Antenna to BBU
The antenna captures and transmits RF signals, the RRU processes and converts them into digital data, feeders ensure signal integrity, and the BBU manages overall base

In a distributed base station architecture, the traditional macro station equipment have two distinct units based on their functions: the BBU and the RRU. The BBU centralizes
We develop high-accuracy models to profile 4G and 5G base station energy con- sumption, revealing 5G inefficiencies under low traffic loads. We identify energy efficiency traps where
By centralizing BBUs in secure facilities while distributing RRUs across tower sites, operators achieve 92% faster field upgrades through software-defined radio reconfiguration.
For outdoor scene: Per BBU can connect 4 RRUs. For indoor scene: FSWs and pRRUs can be connected by using star topology. Each BBU can connect to a maximum of 32 pRRUs through
Discover how BBU and RRU work together via CPRI/eCPRI for efficient 5G signal transmission. Learn about functional splits, latency control, and O-RAN advantages.
