Super Wi-Fi
Super Wi-Fi 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 access.[1][2] 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.[1] A trade show has also been called the "Super WiFi Summit" (without hyphen).[3] Various standards such as IEEE 802.22 have been proposed for this concept.
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.[4] These lower frequencies allow the signal to travel further and penetrate walls better than the higher frequencies previously used.[4] The FCC's plan was to allow those white space frequencies to be used for free, as happens with shorter-range Wi-Fi and Bluetooth.[4]
On April 19, 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 2.4 GHz Wi-Fi.[5]
On May 8, 2011, a public Super Wi-Fi network was developed in Calgary, Alberta. Calgary based company WestNet Wireless. launched the network for free and paid subscribers.[6]
On January 26, 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.[7]
On July 9, 2013, West Virginia University launched the first campus Super WiFi network.[8]
