UAV Propagation Channel Characteristics in SHF Band

Consumer drone technology is a rapidly evolving field and expected to revolutionize the world in wide aspects. Drones' air traffic control is coming in near future with high priority requirement as part of national airspace system. Massive number of flying drones require frequency band that can support high throughput and very short latency. Current UHF frequency bands reach their capacity limit. In this work, we investigate propagation characteristics of the radio channel in super high frequency (SHF) band as the expected operating band for wireless controlled drones. The presented radio channel characteristics cover effect of frequency range, in terms of path loss and pattern propagation factor behavior with vertical and horizontal polarization.
