Klaus Ernst writes and images from New York City with his experience with the free CBS OpenZone network: CBS's outdoor advertising division launched the service in November 2007; Ernst finds performance is all over the board. "The 47th Street Subway entrance has the "CBS mobile ((ZONE)) surf the web here. Free!" orange banner (see picture) but there was no hotspot. Maybe next time." He tested across Broadway and found a couple more working nodes, although one lacked a banner, advertising, or a splash page for accepting terms of service--but it worked.
"Well, it's not hopeless, but CBS is definitely not blanketing the area with Wi-Fi the way they made it sound in the press release," Ernst writes. Ernest tests with an Asus and HP iPaq.
