What is a remote radio unit?

A remote radio unit (RRU), often called a remote radio head (RRH), is a transceiver on a wireless base station. These transceivers connect wireless devices to wireless networks, allowing them to send and receive text messages, among other things. The RRU is one of the two main units of a wireless base station. The RRU is the radio frequency processing unit; it sends and receives signals. You'll usually find the RRU on top of the base station, mounted near the antenna. RRU can receive, transmit, filter and amplify RF signals.



Every time you send a text message, your phone sends a digital signal to nearby cell towers, or base stations. When the base station receives the signal, the RRU is responsible for converting it into a radio frequency signal and transmitting it to the BBU of the base station. The optical fiber connects the RRU and the BBU. The BBU is then able to send a signal to cell towers near the person you are texting
