Backhaul connecting the RAN with core networks has long been the unsung, unglamorous, part of the mobile delivery chain, but that is changing as newer options such as satellite, mmWave and IAB (Integrated Access and Backhaul) figure increasingly. Backhaul is gaining more prominence as a key component in provision of connectivity in remote areas and inshore areas. The various options may be combined to deliver global connectivity for general use or specific cases. Historically backhaul has been mostly provisioned over fiber or microwave connections, along with some copper, with the relative growth of each being driven by trends in deployment and demand. While 5G was being rolled out rapidly in leading economies, this drove fiber because of its greater capacity…
