The Chicago Transit Authority (CTA) will install a wireless communications system in its subway tunnels, underground stations and station passageways. The system will allow CTA to contract use of the Subway Wireless Telecommunications System to Chicago-area wireless service providers. That would allow customers to use cell phones, e-mail, wireless Internet, paging and text messaging throughout the CTA's 11.4-mile subway system. The communications system will also enhance the CTA's existing two-way radio system and improve redundant subway communication options for CTA, Chicago Police Department and Chicago Fire Department/EMS personnel. Work on the project will begin in the spring and last about 18 months. During the first phase, radio transmitters, receivers and antennae will be installed and interconnected with existing fiber optic cable to enable voice and data connection services. The CTA does not anticipate service interruptions during installation. For more on the project, go to the CTA's Website at www.transitchicago.com.
