4T4R Pipe-Mounted RRU

4T4R Pipe-Mounted RRU

Communicates with the Baseband Unit (BBU) via optical fiber for I/Q data and Operation and Maintenance (O&M) messages.

Connects to antennas or leaky cables via RF cables to transmit and receive radio frequency signals.

The downlink channel converts baseband signals into RF signals and transmits them through the antenna.

The uplink channel converts the RF signals received by the antenna into baseband signals and sends them to the BBU.
