Nokia and China Unicom claim this is the first network with 4G and 5G running on the same cloud infrastructure.
There is a lot of work required to virtualize the RAN and standards groups like the xRAN/O-RAN Alliance and the 3GPP can’t do it all, says Cisco.
The xRAN Forum is in the process of becoming part of the O-RAN Alliance. The merger was announced last February but is taking a long time to be formalized.
AT&T’s Andre Fuetsch will head the group’s board, which is made up of delegates from 12 operators.
Groups like the ORAN Forum, Cisco’s Open vRAN initiative, and TIP’s OpenRAN Group are all working to virtualize the RAN. The Linux Foundation has kept its distance, so far.
The next phase of the operator's 5G trials will include at least 100 base stations in each of the five test cities. The trials will use equipment from multiple vendors including Ericsson, Nokia, Huawei, and ZTE.
From shrinking booths to crowd control workers, here’s the latest from MWC.
The RAN is the most expensive part of the network.
C-RAN trials are happening today with three operators.
