Abstract

A wireless communication method includes receiving, by an external device, a request to transmit data to an aircraft, in response to a triggering condition being satisfied, switching a communication electric circuit of the aircraft from operating a first software defined ration (SDR) firmware to operating a second SDR firmware, and receiving, by the aircraft, data to be transmitted. Communication electric circuits of the aircraft and the external device are respectively configured to execute corresponding SDR firmwares to establish communication links. The first SDR firmware is configured to establish a communication link of the aircraft, and the second SDR firmware is configured to establish a communication link of the external device. A bandwidth of a communication link of the aircraft operated with the second SDR firmware is broader than a bandwidth of the communication link of the aircraft operated with the first SDR firmware.
