Chicago to implement 4G wireless service in all metro stations and tunnels

CTAChicago will be the largest public transit system in the U.S. with 4G coverage in all metro stations and tunnels and the target to be completed is set by the end of 2015.
Mayor Rahm Emanuel announced a USD 32.5 million deal, brokered by the Chicago Infrastructure Trust,with America’s four major wireless providers – T-Mobile, AT&T, Verizon, and Sprint – to finance a network modernization project for the Chicago Transit Authority (CTA) to upgrade the wireless network in the City’s subway system. T-Mobile, AT&T, Verizon, and Sprint have collectively agreed to fund the entire upgrade related to the design and construction of a next-generation Distributed Antenna System (DAS) capable of supporting the latest 4G wireless networks and mobile devices.
“By adding 4G wireless service all throughout the CTA, we are bringing 21st century technology to every rider on every line of our 21st century transit system. This is another way that we are investing in a modern CTA to encourage ridership, make Chicago more economically competitive, and open up more economic opportunities to more residents throughout the city,” Mayor Rahm Emanuel said.
The network upgrade, which began earlier this month, will help improve first responder communications throughout the tunnel system, while also giving the millions of Chicago subway riders the opportunity to have a faster mobile experience throughout their commutes.
