The sound of the underground

29 Mar 2012

Passengers on Tokyo’s underground subway system will be able to access cellular services for the first time from this week. Japanese cellular network operators NTT DoCoMo, KDDI, Softbank Mobile and eMobile have been working together to deploy wireless networks underground. Previously, coverage was only available in some areas of certain stations, but the operators are now to provide a signal throughout the entire tunnel system. The first section of the subway network to get a service will centre on Shinjuku, a central business and shopping district, IDG News Service reports. There are opponents to the move, however; for some time the subway system has been one of Tokyo’s only mobile-free zones, and there is now concern that the peace could be shattered for good.
