Wireless Communication with UAV

Download to read offline

An unmanned aerial vehicle, commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system, which includes adding a ground-based controller and a system of communications with the UAV. UAV's can be used in wireless communications.
