Cablevision is close to wrapping up negotiations that will allow it to deploy Wi-Fi service on commuter trains in New York, New Jersey and Connecticut. Our sister publication FierceCable reports that Cablevision executives say the company is working on agreements with New Jersey Transit and Metropolitan Transportation Authority, which runs the Long Island Railroad, and Metro North, which is used by commuters in Connecticut and New York suburbs such as Westchester. Cablevision has installed more than 80,000 Wi-Fi access points throughout its footprint, including train stations. Adding Wi-Fi transmitters to the trains would give it another weapon in its battle against Verizon for broadband subscribers. The initiative could also aid Comcast and Time Warner Cable, which have a roaming pact with Cablevision that allow the top two MSOs to offer their subscribers access to Cablevision's hotspots.
