Scary. Insane. Ridiculous. Invasive. Wrong. The Washington Post reports that the FBI has had the ability to secretly activate a computer's camera "without triggering the light that lets users know it is recording" for years now. What in the hell is going on? What kind of world do we live in?

White-fi is a term being used to describe the use of a Wi-Fi technology within the TV unused spectrum, or TV white space. The IEEE 802.11af working group has been set up to define a standard to implement this.
With a number of administrations around the globe taking a more flexible approach to spectrum allocations, the idea of low power systems that are able to work within portions of spectrum that may need to be kept clear of high power transmitters to ensure coverage areas do not overlap is being seriously investigated.
When using systems like white-fi, IEEE 802.11af that use TV white space, the overall system must not cause interference to the primary users. With processing technology developing further, this is now becoming more of a possibility.
There are many benefits for a system such as IEEE 802.11af from using TV white space. While the exact nature of the IEEE 802.11af system has not been fully defined, it is still possible to see many of the benefits that can be gained:
Looking at these benefits, it is believed that the White-Fi system offers sufficient advantages to enable development to be undertaken.
In order for white-fi 802.11af to be able to operate, it is necessary to ensure that the system does not create any undue interference with existing television transmissions. To achieve this there are a number of technologies and rules that may be utilized.
With pressure on radio spectrum increasing all the time, it is necessary to utilize the available spectrum as efficiently as possible. One method of helping to achieve this is utilize radio technology that is able to sense the environment and configure itself accordingly - Cognitive Radio. The technology is heavily dependent upon Software Defined Radio technology as the radio needs to be configurable according to the prevailing radio environment.

The table below gives a summary of the salient features of 802.11af.
802.11AF CHARACTERISTIC | DESCRIPTION |
---|---|
Operating frequency range | 470 - 710MHz |
Channel bandwidth | 6MHz |
Transmission power | 20dBm |
Modulation format | BPSK |
Antenna gain | 0dBi |
The proposal for the implementation of White-Fi si sill in its draft or development stages. However it provides an effective way or accessing more radio spectrum in an area where available bandwidth is at a premium, and utilising the resource more effectively.
