The Evolution of the Remote Radio Unit for Modern Cellular Networks
With the evolution of cellular network technology, the need for compact, flexible and efficient remote radios has never been greater. Let's take a look at what remote radio units are and how they are enabling next-generation networks.
What is it?
A Remote Radio Unit is a small radio transceiver that is remotely located and connected via a cable to the main base station hardware. RRUs allow the radio interfaces—including antennas and RF power amplifiers—to be separated from the baseband unit (BBU) and digital signal processing resources. This separation of components enables more flexibility in deployment.
Benefits of Remote Radio Architecture
There are several key benefits that the remote radio architecture provides over traditional base stations:
Improved Coverage - By separating the radio components, antennas can be placed in optimal locations for coverage like rooftops rather than being constrained by the base station equipment cabinet. This improves signal propagation and extends coverage area.
