* Comcast, Time Warner Cable, Cablevision offer free Wi-Fi
* Wi-Fi is free in New York to their Internet customers
NEW YORK, April 15 (Reuters) - Customers of Comcast Corp (CMCSA.O), Time Warner Cable Inc TWC.N and Cablevision Systems Corp CVC.N will soon be able to use their Wi-Fi-enabled devices in the New York metropolitan area even if they're out of range from their local cable company.
The three companies said on Thursday that they had reached an agreement to allow their respective high-speed Internet customers to roam freely across each of their Wi-Fi networks with devices like laptop computers and Apple Inc's (AAPL.O) iPad.
The cable companies have been building out free Wi-Fi services for their customers across their respective regions at locations like major train stations and public parks.
Customers can access all three Wi-Fi services and sign on to their own provider's network.
By offering free Wi-Fi as part of their fixed-line Internet service, the cable companies hope they can beat back competition from paid-for wireless Internet services from phone companies like AT&T Inc (T.N) and Verizon Communications (VZ.N).
All three cable companies jointly cover most of the New York City metropolitan area, including parts of New Jersey. (Reporting by Yinka Adegoke; Editing by Lisa Von Ahn)
