Live Event Performer Tracking for Digital Console Automation Using Industry-Standard Wireless Microphone Systems

The ever-increasing popularity of digital consoles for audio and lighting at live events provides a greatly expanded set of possibilities regarding automation. This research works toward a solution for performer tracking using wireless microphone signals that operates within the existing infrastructure at professional events. Principles of navigation technology such as received signal strength (RSS), time difference of arrival (TDOA), angle of arrival (AOA), and frequency difference of arrival (FDOA) are investigated to determine their suitability and practicality for use in such applications. Analysis of potential systems indicates that performer tracking is feasible over the width and depth of a stage using only two antennas with a suitable configuration, but limitations of current technology restrict the practicality of such a system.
