Super Wi-Fi, or IEEE 802.22 and IEEE 802.11af as it is technically known, is a term coined by the United States Federal Communications Commission (FCC) to describe a wireless networking proposal which the FCC plans to use for the creation of longer-distance wireless internet. The use of the trademark "Wi-Fi" in the name has been criticized because it is not based on Wi-Fi technology or endorsed by the Wi-Fi Alliance.
Instead of using the 2.4 GHz radio frequency of Wi-Fi, the 'Super Wi-Fi' proposal uses the lower-frequency white spaces between television channel frequencies. These lower frequencies allow the signal to travel further and penetrate walls better than the higher frequencies previously used. The FCC's plan is to allow those white space frequencies to be used for free, as happens with Wi-Fi and Bluetooth.
US Federal Communications Commission's approved the rules for "white spaces" on September 23, 2010.
In April 2011, Rice University, in partnership with the nonprofit organization Technology For All, installed the first residential deployment of Super Wi-Fi in east Houston. The network uses white spaces for backhaul and provides access to clients using 2.4GHz Wi-Fi.
On January 26th, 2012, the United States first public Super Wi-Fi network was developed in Wilmington, North Carolina. Florida based company Spectrum Bridge, Inc. launched the network for public use with access at Hugh MacRae park.
