BETHPAGE, N.Y., July 22, 2009 -- Cablevision Systems Corp. (NYSE: CVC) today announced that it has successfully deployed Optimum WiFi wireless Internet access in New York's Rockland and Orange Counties, as a free enhancement for its Optimum Online high-speed Internet customers. The newly activated areas -- which are focused on the places where people shop, dine, commute and meet -- cover municipalities such as: Nanuet, New City, Nyack, Pearl River, Spring Valley, Suffern, Central Valley, Greenwood Lake, Harriman, Monroe, Tuxedo, Warwick, and Woodbury. The service is also available at New Jersey Transit train station platforms and parking lots, including: Harriman, Nanuet, Pearl River, Sloatsburg, Spring Valley, Suffern, and Tuxedo.

Optimum WiFi spans thousands of access points, and offers wireless Internet capability across the company's New York, New Jersey and Connecticut service areas. In addition to Rockland and Orange Counties, Optimum WiFi is broadly available across Westchester, Bergen, and Passaic counties, and on hundreds of commuter rail platforms and station parking lots across New Jersey Transit, Metro North, and the Long Island Railroad.

"Unlike many expensive cell phone data plans that can cost upwards of $100 per month, Optimum WiFi is free and more than twice as fast as many cellular networks," said Kevin Curran, Cablevision's senior vice president of wireless product development. "Now, Optimum Online customers in Rockland and Orange counties have unfettered access to the nation's largest and most advanced WiFi network in downtown areas, near parks, and at train stations."

Since its launch in September of 2008, Optimum Online customers have accessed the Internet more than three million times for free over Optimum WiFi, and are averaging more than a million minutes online every day over the network, which delivers speeds of up to 3.0 Mbps downstream. Additional information and detailed coverage maps are available at http://www.optimumwifi.com.

Current Optimum Online customers can access Optimum WiFi using laptop computers and portable WiFi-enabled devices like the iPhone, iPod touch and BlackBerry. Consumer electronic manufacturers have embraced WiFi technology, with more than 5,000 different types of devices currently available in the marketplace that are certified to operate over WiFi. At a recent developers conference, Apple® reported that it has sold more than 40 million WiFi-enabled iPhones^tm and iPods® thus far. Some BlackBerry® smartphones such as the Curve, Bold, and Pearl can operate over WiFi with cellular service providers such as AT&T, T-Mobile, and Sprint. Verizon Wireless currently blocks WiFi on most of its customers' smartphones, making it impossible for these customers to take advantage of the speed and convenience of broadly available WiFi.

Optimum Online customers using devices that are enabled with WiFi -- the same wireless Internet standard more than half of Cablevision's Optimum Online customers use at home through wireless broadband routers -- can access Optimum WiFi through a simple sign-on screen, where the customer logs in by entering their Optimum User ID and password.
