A Remote Radio Unit (RRU) is a key element of a distributed base station architecture in modern cellular networks. It is typically mounted on a tower, rooftop, or pole close to the antennas, where it processes radio frequency (RF) signals for communication between mobile devices and the core network.
RRUs are responsible for?
✔ Amplifying RF signals for better wireless coverage. ✔ Converting digital data into radio signals and vice versa. ✔ Reducing signal loss by being closer to antennas instead of relying on long cable connections. ✔ Supporting multiple frequency bands for 4G LTE, 5G, and beyond.
By deploying RRUs, mobile network operators can achieve higher network efficiency, better call quality, and faster mobile data speeds.
