Cablevision said today it now offers Wi-Fi access to commercial and high-traffic locations across its Long Island, Connecticut and Westchester/Dutchess service areas as an additional service for its high-speed Internet customers. Commuters may enjoy the fact that the Wi-Fi is also available on the commuter rail platforms and station parking lots across Long Island as well as many Metro North stations.

Cablevision touts the move as doubling its Wi-Fi network since its deployment a month ago, but it is easy to double things when they start small. Still, the Cablevision vision is impressive, with plans to offer Wi-Fi across the entire Tri-State area within two years. The Wi-Fi network delivers symmetrical speeds of up to 1.5 Mbps, which is currently faster than the data rates my 3G modem gets.
