Chicago Transit Authority now Has 4G Throughout Blue and Red Lines

Chicago's subway system now has 4G coverage across its entire red and blue lines, its two busiest, said a news release from the Chicago Transit Authority (CTA). The 4G wireless project is a $32.5 million agreement brokered by the Chicago Infrastructure Trust, with the four major wireless providers -- AT&T, Sprint, T-Mobile and Verizon -- to finance the buildout, the release said. Over the past four years, several technology improvements implemented for Chicago’s transit system have included expansion of CTA Train Tracker and Bus Tracker functionality, digital displays with service information at bus shelters and rail stations throughout the service region, and an expanded security camera network, the release said. All CTA subways and tunnels now have wireless phone coverage, the release said.
