Managing the surge of mobile data demand, particularly in dense urban areas, continues to cause headaches to carriers. The nature of cellular networks means the only way forward is the densification of the network. As the number of cells multiplies, the probability of having easy access to fiber when building each new site decreases. Well-proven microwave technology has conveniently solved such challenges in the past, but the typical 15 to 23GHz bands have begun to saturate. This potential spectrum crunch for small cell backhaul presents mobile service providers with the necessity of choosing between other alternatives, of which the 10.5GHz, 26GHz and 28GHz bands are the most interesting immediate options. These already show considerable occupancy, especially in Europe. In addition,…
