Base station RRU battery requirements

What is RRU power system?

By performing radio frequency signal processing, the RRU ensures that users receive high-quality communication. The base station power system serves as a continuous "blood supply pump station," responsible for AC/DC conversion, filtering, voltage stabilization, and backup power.

What is a base station power supply?

This acts as the “blood supply” of the base station, ensuring uninterrupted power. It includes: AC distribution box: Distributes mains power and offers surge protection. Switch-mode power supply: Converts and stabilizes power while managing DC output. Battery banks: Serve as backup power to keep systems running during outages. 3.

What is a BBU in a base station?

The BBU is a key element of the base station's architecture. Unlike the large cabinet setups of the past, modern BBUs are compact and resemble distributed devices, similar in size to DVD players. Function: Processes baseband signals, which are low-frequency signals in their raw, unmodulated state.

What is the efficiency standard for a backup battery charger system?

What efficiency standard applies to a backup battery charger system? The standard requires that backup battery charger systems consume no more than 0.8 + 0.0021 x Eb watts in maintenance mode, where Eb is the battery capacity in watt-hours. Why don’t backup battery charger systems have an efficiency standard for active charging mode?
