Coverage

What does this patent actually cover?

Systems and methods are provided for a network of relay drones utilized as a set of relays or linkages between a base station and a working drone controlled by the base station. The relay drones in the network may augment a communication link or communication signal between the base station and working drone. Relay drones may augment the communication link by acting as nodes that relay communication between the base station and the working drone by boosting the communication signal at each node to compensate for loss of signal power over a traveled distance and/or providing a path with a direct line of sight between the base station and working drone. Directional antennas may be utilized when a direct line of sight is established, which may improve communication signal efficacy when compared with omnidirectional antennas.
