Wi-Fi has competition.

So-called "Super Wi-Fi," which offers a bigger range than existing hotspots, is being deployed in the U.S and is generating interest in a number of countries, including Britain and Brazil.

Super Wi-Fi is not really Wi-Fi because it uses a different frequency and requires specially designed equipment, but it offers some of Wi-Fi's advantages, and more.

The name was coined by the US Federal Communications Commission in 2010, when it approved the deployment of unused broadcast television spectrum, or so-called "white spaces," for wireless broadband.
