It appears that technologists have found an enormous potential in the “White Space” technology and are demonstrating relentless efforts to make the connectivity ecosystem somewhat better.
White space, in telecommunications, is referred to the frequencies allotted to a broadcasting service but is unused. The unused frequencies are considered to have potential for provide wireless broadband Internet access. A device that can be used with such tech is called “white-space device” (WSD).
The U.K. telecoms regulator, Ofcom, has flagged off the commercial availability of the white space spectrum that they extracted out off the TV frequencies. The move has been implemented post a thorough trial carried out under the directions of Google, Microsoft and other public and private organisations across the UK.
In its report, Ofcom stated-
The framework set out here is intended to allow use of TV white spaces to get underway and provide an opportunity for markets in both applications and equipment to develop whilst also achieving our aim of ensuring a low probability of harmful interference to existing users.
Ofcom hopes to deploy the white space technology in UK by the end of this year. Currently, the white spaces will be extracted from 470 to 790 MHz frequency band only. Numerous WSDs in UK will be able to use the unused parts of the radio spectrum in this frequency band.
Well, it’s not a child’s play to extract the unused spectrum without causing interference to the primary channel. To avoid harmful interference being caused to existing spectrum users, databases will apply rules, set by Ofcom, to put limits on the power levels at which these devices can operate.
Ofcom boasts about UK being the very first country in the entire Europe to being out such a technology that promises a good future and will form a major part of the “Internet of Things” (IoT).
There aree countless countries where spectrum conditions are not worth praising and can be refined up to a lot better. If this technology works out, other countries will soon be witnessing it changing the connectivity landscape of their country.
A little while ago, Microsoft expressed its intentions to use “White Space” technology in India, a country where spectrum usability is not so astounding. The company said that by making use of this unused part of the spectrum, they would roll out a free internet connection to remote areas and further expand the project.
