Each day, between the hours of waking, working, and sleeping, we unconsciously interact with an incredible variety of unlicensed devices. From controlling the garage door and monitoring the baby, to microwaving breakfast and speaking on a cordless phone, to keyless entry to a workplace and turning off the television via remote control, our interactions with unlicensed devices have become second nature. And each day, whether most of us realize it or not, we go to bed not having to pay a cent to anyone for the right to do these things.
