Open RAN: de-risking deployments via unified radio offerings
This report is available to those subscribed to the Mobile Operators and Networks module.
Open RAN has featured heavily in technical news over the past few months. A recent development is vendors making the last leap to the Uu air interface via unified 4G/5G remote radio unit (RRU) or radio unit (RU) products.
By controlling the RRU/RU layer, radio features can be tuned together with those parts of applications or use cases that, for performance and latency reasons, must be moved out of data centres and closer to the 4G/5G centralised units (CUs). But doesn’t this contradict open RAN’s promise of the mix and match of components across different vendors?
