CTA Subway Cellular Infrastructure

This project provided faster and more reliable voice and data transmission throughout the 22 miles of subway on CTA’s two most heavily used rail lines, Red and Blue. Upgrading to Next Generation Distributed Antenna System (NG-DAS) made Chicago the largest public transit system in the US with 4G coverage in all subway stations and tunnels. Over 40 miles of radiating cable and equipment for two separate cellular base stations were installed.
