Next generation mobile networks envisage ubiquitous communications at very high data rates. This imposes a major challenge to connectivity and capacity for terrestrial urban mobile communications, where the radio propagation fading is extremely severe. An airbased wireless system is expected to improve the coverage, extend the range, enhance the connectivity and reduce the required transmit power when integrated into a terrestrial wireless network. Existing radio channel models for land mobile satellite systems generally consider mobiles moving along roads in open areas such as main highways with low building densities along the sides of the road. New statistical point-to-area radio channel models are required to predict coverage, including locations near buildings, taking into account the height of the air platform.
