Role of Radio Units in Open RAN Networks

Open RAN (Open Radio Access Network / O-RAN) is an approach to building RANs using open and interoperable interfaces, allowing components from different vendors to work together providing following flexibility for the network providers and operators. Open Radio Unit (O-RU) plays a critical role as one of the main building blocks of O-RAN network. The O-RU handles Radio Frequency (RF) processing and Digital Front-End (DFE) functions performing tasks like transmitting and receiving radio signals between User Equipment’s (UEs), digital beamforming, and converting signals between analog and digital formats.

 

O-RUs are connected to the Open Distributed Unit (O-DU) via open Fronthaul Interface over eCPRI (enhanced CPRI). This interface enables vendor interoperability, a cornerstone of Open RAN. Open RAN RUs are scalable based on network load and coverage needs, optionally supporting massive MIMO and beamforming to improve spectral efficiency and user experience.

 

P8820S RU Testing Toolset is a scalable solution designed to meet evolving O-RU testing needs, supporting C/U/S/M-planes and ensuring comprehensive mMIMO testing capabilities. P8820S Radio Unit testing toolset (RU toolset) solutions for O-RU testing enable Network Equipment Manufacturers (NEMs) and OTIC labs to validate the functionality, protocol conformance, performance, energy efficiency and security of radio units by emulating and measuring network traffic over both radio and O-RAN fronthaul interfaces. Solution is designed to meet the range of requirem
