MEASUREMENT OF RF SIGNAL QUALITY PARAMETERS IN THREE DIMENSIONS

A system is presented for collecting measurements of wireless communication parameters throughout an environment. The system includes a wireless vehicle and a test station. The vehicle is configured to move through the environment, and has a radio disposed to receive a test signal and broadcast a reply signal. The test station is configured to wirelessly communicate with and control the wireless vehicle, and includes a test signal transmitter, a reply signal receiver, and a data collection and processing system. The data collection and processing system is configured to calculate wireless signal quality parameters characterizing signal quality between the test station and the vehicle at a plurality of locations of the vehicle as the vehicle moves through the environment, based on difference between the test signal and the reply signal at each location.
