The revolutionary Super WiFi – TV White Space explained

A few weeks ago, we published an article on how Microsoft TV will use White Space in Africa and India to enable Internet connections to the most remote areas. In areas where it is not even possible to install a mobile tower, TV white space technology will help people connect to the Internet using fixed devices at home or school. The article explains what TV White Space is and mentions some interesting points you should know about the upcoming TV White Space revolution. This phenomenon is also called Digital Disruption, which can affect large Internet access providers, intensify competition and reduce the average cost of Internet access.

What is TV White Space & Super WiFi

You know that TV channels use different frequency ranges to send content to your TVs. They maintain a gap between adjacent bandwidths so that the content of one channel does not interfere with the content of another channel. This space is called the buffer space. There is still a lot of space between two adjacent television channels. And if you take into account all the TV channels you have, there is a huge amount of unused space – although spread over different bandwidths in parallel.

The exact frequencies used to broadcast TV channels vary from country to country, so I cannot give an estimate of the availability of TV White Space. You can try it on site with existing tools.

Super Wi-Fi or TV White Space

February 2021 Update:

We now recommend using this tool for your error. Additionally, this tool fixes common computer errors, protects you against file loss, malware, hardware failures and optimizes your PC for maximum performance. You can fix your PC problems quickly and prevent others from happening with this software:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.


White Space TV technology is also known as Super WiFi because its range is much wider than normal WiFi. According to Carlson Technologies, while WiFi covers a few feet, Super WiFi can have a range of 10 km. This is almost ten times longer than ordinary WiFi.

The main problem with normal WiFi is that they become weak in space and cannot clear obstacles, so they cannot be used in hilly terrain or in forest. Super WiFi has no such problems. He can bend and bounce over obstacles to continue.

How TV White Space works

Carlson Technologies has created a two-minute video showing how the Rural Connect program works. Microsoft and other companies may use a different technique. If you are interested, click on the video below to see Carlson’s answer to the question about how TV White Space works.

Identify the white TV space available in your area and buy it

The Google Spectrum Database will help you determine the free space available in your area. Another Spectrum Bridge tool is Show my white spaces. You can also use them to check the white space of the television available for purchase or use.

In addition to these two automated tools, you can also contact Carlson Technologies, which is contributing to the White Space TV revolution. If you are interested in providing Internet or cable services through TV White Space, you can purchase some of the unused spectrum through these people.

Microsoft now leads the use of white space for television

Microsoft has tested the technology several times with several partners in the United States and now intends to make the Internet available at low cost to developing countries. Although his main focus is on Africa, he is also building infrastructure in India after the Prime Minister pushed the’Digital India’ agenda forward. On the same line, Facebook and Google also offer free Internet, but they are not linked to Super WiFi.

Microsoft intends to reserve various unused spectrum and install base stations linking even the most remote regions of Africa. The continent has the lowest percentage of Internet users. h Television and mobile phones are everywhere. People use GPRS to connect to the Internet, but this option is expensive. And in many areas, mobile phone signals cannot be reached due to terrain. In order to connect these areas and offer Africans an affordable Internet, Microsoft is working with various companies. They install ground stations wherever possible to keep the Internet up and running.

Infrastructure needed to use white TV space for the Internet

I would like to emphasize once again that a terrestrial station can cover an area of 10 km (imagine a circle with a radius of 10 km), so that Microsoft must use certain technologies to keep the Super Wi-Fi operational – every 10 km. Could be something like towers.

At the time of writing this document, no super WiFi handheld devices are available, so the ISP and users must use an external device to use White Space Internet TV.

Up to now, no computer has had built-in hardware that allows direct use of TV White Space Internet. This is a fixed device that connects to the router and from there to the computer(s) to provide Internet access.

Microsoft has not specified what the costs are and how it intends to use this technology to reach the most remote regions of Africa or India, but it indicates that Super Wi-Fi will gain a lot of ground by the end of 2016 and that the costs for businesses, users, user devices and repeaters/towers etc. will be clearer.

Since the white space of television concerns the Internet, it also applies to the Internet of Things. Devices can communicate with each other via super WiFi frequencies.
