AI Technical Summary

Problems solved by technology

In these conventional systems, the UAV's power supply may be depleted faster than required, requiring frequent replenishment or replacement of the power supply
Additionally, by continuously transmitting signals using the maximum transmit power level, use of legacy systems may result in increased interference with other wireless communication devices in the vicinity

Abstract

Methods and systems for controlling a transmission power of a communication device of a movable object may include or be configured to carry out the steps of determining a distance between the movableobject and a second object located outside the movable object; determining a transmission power level based on at least the determined distance between the movable object and the second object and atarget signal-to-noise level for signals received at the second object; and transmitting signals from the movable object to the second object based on the determined transmission power level.

Description

[0001] Copyright Notice [0002] Portions of the disclosure of this patent document contain material that is protected by copyright. The copyright owner has no objection to the facsimile reproduction by anyone of this patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but reserves all copyright rights. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to systems and methods for controlling the transmission power of wireless communication devices in movable objects, such as unmanned aerial vehicles. Background technique [0004] Unmanned aerial vehicles (UAVs), sometimes referred to as "drones," may be configured to carry payloads, such as cargo, optical equipment (eg, cameras, video cameras, etc.), sensing equipment, or other types of payloads. UAVs are recognized in many industries and in many cases are considered a useful tool for offloading t...
