Millimeter's E-Band Deployment Grows Faster than Fiber Optic


In mid-November, Ericsson released its Microwave Outlook 2021 assessment. One of its key findings is that millimeter-wave deployments in the E-band (71 to 86 GHz) are continuing to build momentum. Ericsson states, “E-band, an essential part of 5G wireless backhaul support, is now spreading from the large uptake in Eastern Europe and Central Asia, to Western Europe, the Middle East, Latin America and Africa.” This concurs with ABI Research’s own cellular backhaul research study, Fixed Wireless in the 5G Era (AN-5477). For mobile operators, fiber optic may be the optimum solution for cellular backhaul, but the logistics and capital expenditure of distribution are constraining deployment. In particular, Ericsson comments that fiber-optic deployment for cellular backhaul in North America has largely stalled; it is E-band links that are taking up the slack. While fiber will play an important role, microwave/millimeter-wave backhaul will account for the majority of global backhaul links from 2021 to 2027, with about a 65% market share, accord…
