Summary:Terrestrial microwaves relying on a CLOS link is often the technical design approach because of its ability to enable rapid and cost-effective buildout and deliver backhaul high capacities. [...]a significant percentage of cell sites globally use terrestrial CLOS microwave backhaul. CHALLENGES USING NLOS LINKS Historically, diffracted NLOS radio links have received little modeling or validation attention since the hallmark work by Longley and Rice.4 Although much of this found its way into the International Telecommunications Union (ITU) standards5'6 and into available predictive software tools,7'8 NLOS links are largely in the category of "put it in and see what happens," rather than a fundamental backhaul design methodology. A key concern of the wireless network design community is the prediction of radio link availability and performance. In other cases, reaching a remote cluster of settlements can be impeded by challenging terrain between a developed part of the network and a target coverage area where new radio access network deployments are required.
