There was great rejoicing when cities started talking about providing free municipal Wifi. Now there seems to be great back-pedaling going on.Recently San Francisco and Chicago are re-evaluating their plans. It looks like Earthlink’s financial woes is a key factor in the possible pull backs, as is the revenue model to keep this networks humming. Apparently there are about 175 muni-WiFi projects on the books at the moment. Chicago is also now working with Sprint’s WiMax initiative, so maybe there is still some hope for the Windy City connectivity.
