Wireless [From the Editor]

Wireless technology is pervasive in our world today. Everywhere we look, we encounter some sort of wireless device—be it the mobile telephone in our pocket or the garage door opener in our car. We see wireless devices in our home in the form of remote controls for our televisions, video games, local networks for our computers, or remote controls for difficult-to-reach electric fans. Because of these and other wireless-controlled devices, our coffee tables are loaded with remote control transmitters.
