Don't you hate it when you lose signal the moment you get into a subway? In one minute, you go from 4 strong bars to probably searching for any signal. Luckily for the commuters who use AT&T in the Chicago area, they will be getting a a surprise in the form of better cell phone
coverage in Chicago's subway rail network. AT&T and the city transit authority came together for a 10 year contract to offer coverage on the Red and Blue line subways. Although they are the fourth provider to get on board, Cricket, Verizon Wireless, and U.S. Cellular already had a head start. All in all, the CTA is expected to generate a minimum of $3.1 million over the course of the agreement. So now you won't have to fear about taking that important call when entering the subway.
