Open-RAN Architecture

Open-RAN Architecture

News: The Ministry of Communications has signed a Memorandum of Understanding (MoU) with M/s VVDN Technologies Private Limited to facilitate registered startups, innovators and MSMEs working in the field of Open RAN (Radio Access Network) to get their product tested at the existing lab of M/s VVDN.

About:
• Open-RAN is not a technology, but rather an ongoing shift in mobile network architecture that allows networks to be built using subcomponents from a variety of vendors.
• O-RAN has an open, multi-vendor architecture for deploying mobile networks, as opposed to the singlevendor proprietary architecture.
• O-RAN uses software to make hardware manufactured by different companies work together.
• The key concept of Open RAN is ‘opening’ the protocols and interfaces between the various subcomponents (radios, hardware and software) in the RAN.

Radio Access Network
• It is the part of a telecommunications system that connects individual devices to other parts of a network through radio connections.
• A RAN resides between user equipment, such as a mobile phone, a computer or any remotely controlled machine, and provides the connection with its core network.
• Elements of RAN include Radio Unit (RU), Distributed Unit (DU) and Centralized Unit (CU).

Advantages:
• An open environment expands the ecosystem, and with more vendors providing the building blocks, there is more innovation and more options for the Operators. They can also add new services.
• It will open new opportunities for Indian entities to enter into the network equipment market.
• The benefits of this approach also include increased network agility and flexibility, and cost savings. It’s expected to make 5G more flexible and cost efficient.
