With 5G only just out of the blocks and promising revolutionary use cases that have yet to materialize, it might seem premature to talk about 6G. It might also seem that 5G will be a hard act to follow in terms of its disruption for both operators and customers, certainly at the enterprise level, with the advent of millimeter wave, aggregated spectrum, network slicing, virtualized RAN and private networks. Certainly, perusal of early 6G research suggests that developments will be more iterative, going higher still in spectrum with concomitant further shrinkage of cells. At the same time, automation and flexible network design already in train under 5G will be taken further. The project called 6G Sentinel, cobbled together by five…
