Good news, smartphone-using CTA commuters!


The city is planning on Thursday to announce details of its plan for a major wireless upgrade the underground CTA lines.


DNAinfo Chicago reports the transit agency is planning to outfit all 12 miles of the city's underground lines[1] with 4G service.


The city is now accepting proposals from vendors[2] interested in upgrading the system's existing underground wireless infrastructure, which currently dates back to 2005, according to CBS Chicago, and is leased to six major service providers.


The project is being paid for by the CTA and no timetable has yet been announced.


The CTA revealed earlier this year it was looking into upgrading wireless service underground on the Red and Blue Line and was reaching out to wireless telecommunication companies[3] to determine the particulars of the plan.


“To be a world-class city, Chicago must have a world-class infrastructure, so that people can get around the city efficiently, safely, and productively," Mayor Rahm Emanuel said of the planned upgrade in April.
