Cablevision announced that it has doubled the size of its Long Island wide-area Wi-Fi network to cover locations in Westchester and Connecticut, especially high-traffic areas such as metro and commuter rail stations. Cablevision’s Wi-Fi service is, unfortunately, available only to their existing Optimum Online customers so if you find yourself in their service area and you are from somewhere else, too bad. In that regard, it’s not very useful for outsiders. It’s clear that Cablevision wants to use the service to attract customers away from its competitors in the Long Island region.
