Over 300 million people worldwide carry cell phones. Most of these devices are always on to receive calls. Service providers today can use triangulation or RF multipath "fingerprinting" techniques to locate you within "a few thousand square feet, or up to six square miles in rural areas," according to Bell Labs.
But the noose is tightening. Part of the 1996 Telecommunications Act mandated Enhanced 911 that would force carriers to be able to locate all callers by October 2001. And newer FCC rules require greater precision164 feet for GPS-based phones, 328 feet for network-based triangulation.
The government says that this would help them respond better to the 30 million emergency calls made each year from wireless devices, many of which are made by incoherent or lost callers.
Location-based services (LBS) actually do sound very useful. GPS chips in phones and small tracking devices could locate kids, pets, stolen items, package or pizza deliveries, truck fleets, and anything else that moves.
Even edgier are advanced "trigger-mode" services. You could load your whole phone book into a cell phone and have it alert you when a friend or family member happens to be nearby. You could tell your phone you wanted a new Armani suit on sale and have the phone beep if you went past a store with one in your size at your price.
Your phone could become a matchmaker at a trade show if you needed 10,000 purple widgets and someone across the hall had them in stock. Or it could find you a date or a mate, like an advanced version of Japan's "lovegetties." Some analysts predict LBS will be a $20 billion business by 2005.
But there's a darker side. Several government agencies are claiming that the 1994 Communications Assistance for Law Enforcement Act lets them use this technology to track you legally, without a warrant or even probable cause, in what it deems "emergencies." Do you trust these clowns?
And do you trust others who can get their slimy hands on this data? The highway patrol will know you're traveling at 66mph and be able to pinpoint your location. Ugly gold-digging divorce cases will get even uglier as each side subpoenas logs of all addresses a spouse visited for years. Bosses or the IRS will know how long you stayed away from your desk, or map your precise whereabouts during road trips. Is this what we want?
Service providers balked at the October 2001 deadline, whining that they needed more time to pass on all the costs to the public and wriggle out of any liability issues. The FCC agreed to phase in adoption, moving the deadline for total implementation to the end of 2005. It's coming. And since we can't be without our phones, pucker up and kiss your freedom of movement goodbye. Trust me.
