The Massachusetts Bay Transportation Authority announced plans to extend cell phone coverage to the Blue Line and most of the Green Line by the end of the year. By the end of 2012, the entire underground system will have service and travelers will be able to talk, text, and surf the web in the MBTA’s 35 underground stations and its 19 miles of tunnels. InSite Wireless has a 15-year contract with the MBTA to install and operate the wireless infrastructure at no cost to the authority. In addition, the MBTA will receive approximately $5.2 million for the parts of the system that are already wired; revenues will increase as cell service expands and more carriers sign on.
