As the telecom community searches for reasons why Small Cell architectures have not yet launched en masse, “experts” are quick to suggest that lack of backhaul technology as the key perpetrator.
For years and years, microwave and millimeterwave radio technologies have coexisted without very much overlap in either their markets or applications. Microwave radio served telephone company needs (e.g., long distance backhaul, mobile access aggregation) for the bulk of its implementations with some vertical deployments for oil and gas, public safety and utilities organizations. Typically, licensed bands in service ranged from 6GHz to 42GHz—with 11GHz and under popular for long haul; 18-38GHz trendy for short urban hops. Generally, millimeterwave radio is considered to be between the 60GHz and 80GHz bands and found its applications confined to those for intra-campus communication from building to building for universities, civic centers, other government conglomerations and large, spread-out (i.e., 1 to 5 miles) corporate facilities.
