And we’re also introducing the open interfaces on the management side – so northbound utilising both A1 and O1. In it, Ericsson’s head of Cloud RAN, Mårten Lerner says that now the O-RAN Alliance has adopted Ericsson’s proposal to enhance the Open FH interface, the vendor will support the O-RAN interface that it calls Next Generation open Lower Layer Split.“In the lower layer split we’re introducing the Next Generation open LLS, which is the evolution of the O-RAN split. (Read this piece from MWC 2023 for lots more on this. It says this mainly because it is adopting a category of fronthaul that is being specified within O-RAN Alliance to enable enhanced performance for mmWave. That’s because Ericsson takes the view that its Cloud RAN deployments will proceed in accordance with Open RAN principles. SONIC VISUALISER NOT LAUNCHING SOFTWARENor do we know the hardare or cloud environment in which the RAN software was deployed, although a best guess would be that both were Ericsson, the company has had working demos of its Cloud RAN on Intel-based commercial servers from, for example, HPE.Īn Ericsson press release said that the grial achieved 4Gbps throughput, and posited that mmWave 5G using a Cloud RAN architecture could be applied to data intensive use cases such as FWA and private enterprise networks.Įricsson also took the opportunity to claim that this Cloud RAN trial “serves as a crucial foundation for O 2 Telefónica’s efforts to bring Cloud RAN technology to macro networks and demonstrates Ericsson’s commitment to Open RAN – paving the way for further advancements in cloud-native architecture and operation”. There weren’t many other details forthcoming about the trial set-up, scale, or channel bandwidths etc. The companies said that the test took place at O 2 Telefónica’s Wayra innovation hub in Munich, with a CU connecting to a mmWave radio unit. Telefonica Group has another toe in the Cloud RAN water, with its Germany subsidiary scoping out a mmWave Proof of Concept using Ericsson Cloud RAN baseband software. ![]()
