That's what the Federal Communications Commission would like to see, as explained in this front-page Washington Post article by Cecilia Kang. As you might imagine, some industries like this idea a tad better than others. Here's a short excerpt:
The federal government wants to create super WiFi networks across the nation, so powerful and broad in reach that consumers could use them to make calls or surf the Internet without paying a cellphone bill every month. The proposal from the Federal Communications Commission has rattled the $178 billion wireless industry, which has launched a fierce lobbying effort to persuade policymakers to reconsider the idea, analysts say. That has been countered by an equally intense campaign from Google, Microsoft and other tech giants who say a free-for-all WiFi service would spark an explosion of innovations and devices that would benefit most Americans, especially the poor.
The article goes on to say that some people think that the government-supplied network envisioned by the FCC won't be maintained adequately and/or won't be powerful enough to handle the expected traffic.
