Almost daily, there are headlines about municipal Wi-Fi being rolled out or delayed or debated in cities across the nation. This week, The Economist takes a look at Earthlink in Anaheim to summarize the issues that are popping up everywhere that citywide Wi-Fi is in the works. They discuss the problems that have caused EarthLink to second-guess their involvement in the plans. Breaking down the market-driven model in Anaheim, they look at cost, frequency conflicts with other tech gadgets and other complications. But with 175 regions already building citywide networks and that many more considering plans to do so, is going back on the deal really an option? Maybe we should be looking at the Philly model instead.
