Analogous technologies have been in use around the world since a long time to communicate through radio or the internet such as :
Power Line Networking-PLC, Broad Band over Power line-BPL, Power Line Communication-PLC, Power Line Carrier Communication-PLCC, Digital Power Line Carrier-DPLC, Power Line Telecom-PLT to name a few but the problem is that powerful businessmen that carries macoutload of monies always managed to bribe the influential politicians.

And, the end result is soon or later, the end users or the consumers end up paying exorbitant price for those services even-though some of those services were free in the beginning.

The term 'wifi' has been a general term for the family of 802.11 protocols and products using these protocols.

All Wi-Fi activity takes place on the same 2.4GHz or 5GHz. The term Super WiFi is a mental construct, an attempt to conveying a new idea in a way most people will understand.

The so called super-wifi is not wifi;thus the name of Super wifi is a misnomer; the word Wi-Fi is a trademark, there is no such thing as Super Wi-Fi, and white spaces is not Wi-Fi. There will be a real super wifi coming-802.11 ac that will be called VHT or very high throughput.

That will be the next generation of Wi-Fi in the sense that it brings an even higher data rate more than a gigabit per second.

White space radios use the empty TV channels around you to transmit data. The FCC has opened up a sizable new block of unlicensed spectrum, this time between 50MHz and 700MHz.

White spaces can go longer distances and penetrates physical objects wifi cannot, but at lower data rates due to their relative low frequencies.

The white spaces in the UHF band are treated as unlicensed spectrum, so they are not exclusive to a single wireless carrier; anyone can use them, just like the 2.4-Ghz band used for Wi-Fi, Bluetooth, and cordless phones.

White space radio in the US will most likely use a new standard called 802.22 for "regional area networks." That's different from the 802.11 Wi-Fi "local area network," 802.15 Bluetooth "personal area network," and 802.16 WiMAX "metropolitan area network" scopes, according to the IEEE 802 Working Group Web site.

Initially, white spaces networking will compete with embedded 3G, DSL, and home WiMAX.

It will be a way for wireless Internet providers, especially in rural areas, to zap their network over to a main router in a home, which will then redistribute it to devices over Ethernet or standard Wi-Fi connections.

It can also provide wireless data to a point from which it can be distributed over a network.

For example, to deliver a liv for public Wi-Fi routers, or connect to other fixed devices like smart energy meters which would otherwise use 3G.

You cannot move a white-space device around.

You cannot put a white-space radio into a phone or laptop because each white-space device must check its location against a database to determine which TV channels and wireless microphones are being used in the device's area, so they can avoid those channels.

That may change a few years down the road, when "personal/portable" white space devices appear.

Based on the 802.22 standard, these will be chips able to fit into laptops and tablets, with software that can "sense" clear frequencies as they move around.

Personal/portable white space chips will come by the end of 2012, and chip-sets will often combine white space and Wi-Fi technology.

Personal/portable white space technologies seem better suited for campus-wide and large building-wide networks than for replacing the average home.
