The idea of muni networks has been around for a while, with bipartisan support. When the Telecommunications Act was under discussion in 1994, Senator Trent Lott, Republican of Mississippi, was one of its most enthusiastic supporters. Thanks to him and others, the act, passed in 1996, prohibits states from putting up unreasonable obstacles to any entity that wants to provide telecommunications services.

So why didn’t a thousand muni networks bloom? After all, the 1996 act was aimed at increasing competition. But private providers rightly recognized muni networks as a threat, and in the subsequent decades have pushed through laws in 20 states that, despite the 1996 act, make it difficult or impossible for municipalities to clear the way for the sorts of networks that the 1996 act envisioned.

That means that the main problem behind getting muni networks up and running isn’t about the technology — which not only exists, but is already being used in large and small cities around the world — but about the politics.

As a first step, Americans need to focus their efforts on getting these laws taken off the books. (To its credit, the F.C.C. recently signaled its willingness to help, saying it would consider blocking those laws at the federal level.)

Mere legislative change won’t be enough, however. We need to elect leaders on the basis of their commitment to changing America’s stagnant communications infrastructure.
