Highlander404 sends word of one city that is bucking the trend of failing city Wi-Fi projects: Houston is investing most of the $5 million Earthlink paid to get out of its muni Wi-Fi contract to build out 10 free wireless network "bubbles" in low-income parts of the city. Access points will be in city-owned facilities to keep costs down. Houston's mayor said that over the long term the bubbles could be connected and the areas between them added to the network. The activation of the first of these zones was announced Monday. Upload and download speeds are said to be 3 Mbps.
