Your Cellphone Is Spying on You



Big Brother has been outsourced. The police can find out where you are, where you’ve been, even where you’re going. All thanks to that handy little human tracking device in your pocket: your cellphone.

There are 331 million cellphone subscriptions—about 20 million more than there are residents—in the United States. Nearly 90 percent of adult Americans carry at least one phone. The phones communicate via a nationwide network of nearly 300,000 cell towers and 600,000 micro sites, which perform the same function as towers.

When they are turned on, they ping these nodes once every seven seconds or so, registering their locations, usually within a radius of 150 feet. By 2018 new Federal Communications Commission regulations will require that cellphone location information be even more precise: within 50 feet. Newer cellphones also are equipped with GPS technology, which uses satellites to locate the user more precisely than tower signals can. Cellphone companies retain location data for at least a year.

AT&T has information going all the way back to 2008.
