Multi-protocol radio frequency devices for drones

Abstract

A multi-protocol radio frequency device for unmanned aerial vehicles (UAVs) includes a first transceiver unit, a second transceiver unit, and a controller. Each of the first and second transceiver units includes multiple radio frequency circuit modules using different communication protocols. The controller is electrically connected to the radio frequency circuit modules in the first and second transceiver units. The controller detects the wireless signal strength of the radio frequency circuit modules in the first transceiver unit and switches to one of the radio frequency circuit modules in the first transceiver unit based on the detection results to receive control data. The controller also detects the wireless signal strength of the radio frequency circuit modules in the second transceiver unit and switches to one of the radio frequency circuit modules in the second transceiver unit based on the detection results and the transmission rate to transmit image data.
