What is RRU in Telecom?

November 2016

A Remote Radio Unit (RRU), commonly referred to as a Remote Radio Head (RRH), is a transceiver that you’ll find on wireless base stations. These transceivers connect wireless devices with wireless networks, making it possible to send and receive text messages, among other things.

RRUs are one of two primary units of a wireless base station. The RRU is the RF processing unit; it transmits and receives signals. You’ll typically find the RRU at the top of a base station, mounted near the antenna. RRUs can receive, transmit, filter and amplify RF signals.

The graphic below from Tech Target illustrates where RRUs fit in wireless communications. Every time you send a text, your phone sends a digital signal to a nearby cell tower, or base station. When that cell tower receives the signal, the RRU is responsible for converting it into an RF signal and transmitting it to the cell tower’s BBU. Optical fiber connects the RRU to the BBU. The BBU is then able to send the signal to a cell tower near the person you texted.

As you can see, there’s a lot going on behind the scenes of every text message you send and receive! And this is just the tip of the iceberg.
