Cordless phones, baby monitors, garage door openers, wireless home security systems, keyless automobile entry systems, and other types of common electronic equipment rely on low power non-licensed transmitters, or unlicensed spectrum, to function. This can be a headache for Wi-Fi users because the closer the non-licensed transmitter, the greater the chance for interference, according to High Tech Forum. No wonder you may have had a bad connection the last time you were in the airport!
