Aside from hardware cost savings and boosts in efficiencies, virtualised centralised RANs – also known as cloud RANs – are able to pool together the management of radio resources, notes Jake Saunders, vice president for mobile infrastructure at ABI Research.
“Once all the elements are virtualised, they can be deployed on proprietary commercial off-the-shelf (COTS) servers, and hosted on the cloud,” he explains. “COTS servers can reduce the RAN equipment cost, support dynamic radio resource allocation, and accelerate network deployment and upgrade processes.
“Operators can also create open networks, support multi-vendor and interoperable network architectures, as well as accelerate time to innovation and lower capital expenditure [capex].”
