Drastic improvements have been made to mmWave networks
Observers are now more optimistic about their fitness for fixed link purposes
Adding point-to-multipoint is providing another boost
Improving carrier technology could put microwave at 28 GHz back on its pedestal after three years of reappraisal and tinkering. As originally envisaged by Verizon the spectrum’s primary use may, after all, be as a solution for fixed link broadband. Unfortunately its first outings didn’t measure up to expectations when launched in early 2018. The mmWave signals didn’t propagate well and speeds on both the down link and especially the up link turned out to be slow.
