Massive MIMO antenna arrays, combined with beamforming, will be mainstays of 5G cell sites. The former greatly enhances capacity by allowing up to 1,024 antennas (more, no doubt, in future) to work in parallel; while beamforming enables them to be directed far more precisely, increasing performance and spectral efficiency. Pivotal Commware claims to be taking beamforming a step further with its technology, Holographic Beamforming, and is drumming up OEM and operator support to try to establish industry standards for the advanced approach to “beam management”. As with smart start-ups working on other potential enablers of high 5G performance – like mobile full duplex, for instance – Pivotal knows that, with technology operating at this fundamental radio level, success is reliant…
