I grew up in a time when television had only three channels, the music industry was all up in arms because of the new technology allowing anyone to tape their own music (cassette tapes), and if you needed to talk to someone about something, you had to either meet them face to face or call their one and only home phone (and hope they were there). Oh, sure, the ultra-rich had phones built into their limos (not really much more than glorified CB radio devices actually), but the idea of a cell phone didn’t really hit the public consciousness until sometime in the early 1980s. In fact, the first real foray into the technology came in 1973, when a Motorola researcher created a mobile phone. The handset came in at a stealthy 8 by 5 inches, weighing approximately 2½ pounds, and offered a whopping 30 minutes of talk time.

After a decade or so of further research and attempts at bringing the technology to market, the first analog cellular network (Advanced Mobile Phone Service [AMPS]) hit the United States, and a company called DynaTAC released a device that has been ridiculed in technology circles for decades now—the bag phone. Despite the weight and bulkiness of the system and that it provided only a half hour of talk time and took nearly 10 hours to charge, demand for the thing was incredible, and people signed up on waiting lists by the thousands.

I remember quite clearly how jealous I felt seeing people driving around with those ultra-cool giant-battery phones that they could use anywhere. I even looked into buying one and can remember the first time I slung that big old bag over my head to rest the strap on my shoulder so I could heft the cord-connected handset and dial home. Looking back, it seems really silly, but that strong desire by the consumer population fueled an explosion in mobile device technology that has changed the world.

The wireless revolution touched everything in life—not just the humble phone. We looked at making everything wireless and just knew we could do it. (Star Trek had been showing wireless communication for decades, so why not?) Computer networks were an obvious branch to follow, and seemingly everything else followed. Our wireless technologies are now as much part of life as the light switch on the wall—we wouldn’t know what to do without them, and we all just expect it all to work. Hence the problem.

I’ve said repeatedly that almost every technological implementation designed to make our lives easier and better can be, and usually has already been, corrupted by the bad guys, and wireless tech is no exception. Wireless networks are everywhere, and they’re broadcasting information across the air that anyone can pick up.
