Abstract
A system for RF communications with UAVs which includes two distinct frequency bands, one for optional use to support datagrams between a UAV payload and a computer or controller and a second RF communications band dedicated to command and control and navigation datagrams transception between the UAV and a host controller or control network. Embodiments of the system are implemented to cover, with regard to the second RF communications sub-system, a large region suitable for enabling communications with a number of UAVs by creating a skyward projected cell system, and dividing its frequency range into sub-channels, where sub-bands into which the frequency range may be divided may be used in a re-use scheme.
