Wireless Internet for All, Without the Towers

THESE still are early days for the Internet, globally speaking. One billion people online; five billion to go.

The next billion to be connected are living in homes that are physically close to an Internet gateway. They await a solution to the famous “last mile” problem: extending affordable broadband service to each person’s doorstep.

Here in the United States, 27 percent of the population lacks access to the Internet, according to a study completed last year by the Pew Internet and American Life Project. Among those who do have access, about 30 percent still rely on slow dial-up connections. The last mile for households with no or slow connections may be provided by radio signals sent out by transmitters perched atop street lights, as hundreds of cities have rolled out municipal Wi-Fi networks, or are in the process of doing so.

…

An intriguingly inexpensive alternative has appeared: a Wi-Fi network that is not top-down but rather ground-level, peer-to-peer. It relies not on $3,500 radio transmitters perched on street lamps by professional installers but instead on $50 boxes that serve, depending upon population density, more than one household and can be installed by anyone with the ease of plugging in a toaster.
