AUTONOMOUS ROBOT-ASSISTED INDOOR WIRELESS COVERAGE CHARACTERIZATION PLATFORM

摘要

A wireless coverage characterization platform uses an autonomous vehicle or robot, such as an unmanned aerial vehicle or other small robot, to autonomously collect key wireless coverage parameters for an indoor environment. One or more vehicles or robots are equipped with integrated simultaneous localization and mapping sensors as well as wireless signal measurement sensors. As a vehicle traverses the indoor environment, on-board processing components process the sensor measurement data to simultaneously build an indoor map of the environment and to learn the wireless coverage characteristics of the environment incrementally. The vehicle's navigation system guides the vehicle through the environment based on the sensor measurements and the learned indoor map until a complete map of the wireless signal strength at all locations throughout the environment is obtained. The system can identify areas of weak wireless coverage or interference sources and recommend access point device locations based on results of the survey.
