Rain Rate Retrieval from Millimeter-Wave Propagation Measurements in China

Communication at millimeter-wave frequencies represents the most recent game-changing development for wireless systems. Provided the significant increase in bandwidth and new capabilities offered by millimeter wave frequencies, the base station-to-device links, as well as backhaul links between base stations, will be able to handle much greater capacity than today's cellular networks in populated areas. Governments around the world have allowed operations in the millimeter bands for backhaul, often as little or no licensing fee. In addition to 6–42 GHz, 50 GHz, 60 GHz bands, and recently, the E-bands at 71-76, 81-86, and 92–95 GHz in the USA have become popular, as the spectrum is made available at very little cost to carriers.
