We are still at the early stages when it comes to 5G access networks in terms deployments, specifications, standards and maturation.
At Ericsson, the excitement is real and very ambitious; so that, the launch of its new AIR 6468 cellular radio focuses lots of hopes. Ericsson stated that together with the 5G Plug-Ins announced in June, and the (already available) Radio System Baseband 5216, it now offers all the components of a 5G access network.
Then, one can observe that, AIR 6468 embodies advanced antenna technology that enables beamforming, massive MIMO and multi-user MIMO. The new radio will become commercially available in mid-2017.
