Abstract
An identification tag has at least a controller, a receiver for receiving wireless signals from an exciter, and a transmitter for transmitting wireless signals to at least one location receiver (which may be a WLAN access point). The tag's controller can determine the presence of interference from sources unrelated to the location system, such as smartphones, tablets, computer monitors etc., and signal an alert accordingly.
