What is Open RAN Ericsson?

A radio access network (RAN) is part of a mobile telecommunication system . It implements a radio access technology. Conceptually, it resides between a device such as a mobile phone, a computer, or any remotely controlled machine and provides connection with its core network (CN).

A radio access network (RAN) is defined as the combination of telecommunication network elements used to establish communication between user equipment and the core network . Traditionally, this has included base station components, radios, and antennas that provide cell coverage within a specific area.

What is RAN Automation? Radio access network (RAN) automation automates daily repetitive tasks and processes using intelligent, machine-learning-based functionality focused on the radio network . The radio network is the largest, and most complex part of the communication service provider network.

A vRAN replaces BBUs with Commercial Off the Shelf (COTS) hardware, but the RAN is still dependent on proprietary interfaces and purpose-built hardware for radio transmissions . Open RAN is an effort to open the RAN altogether. “Current RAN technology is provided as a hardware and software integrated platform.

A RAN provides access to and coordinates the management of resources across the radio sites . A handset or other device is wirelessly connected to the backbone, or core network, and the RAN sends its signal to various wireless endpoints so it can travel with traffic from other networks.

Radio access processing platforms in Ericsson Radio System , with RAN Processors, Radio Processors and Basebands. In today’s purpose-built Radio Access Network, the software is running on Radio, Transport and RAN Compute hardware platforms.

Ericsson believes in the value of openness in mobile networks . As an active participant in the O-RAN Alliance, we work together with communication service providers and mobile network suppliers to create the right foundations for openness, innovation and flexibility in radio access networks.
