- The switchover from analogue to digital terrestrial TV, to be completed in Europe by the end of 2012, will free up a very large amount of radio spectrum. This ‘digital dividend’ will provide a unique opportunity to meet the huge demand for new wireless communications services, allow broadcasters to significantly expand their services and at the same time provide spectrum for social and economic uses. Applications in this latter category will include broadband applications which can help overcome the ‘digital divide’: ensuring equitable access to new information and communication technologies to all the people of Europe. Digital "bonus"The digital dividend is derived by the ability of digital compression systems to allow the transmission of up to 8 standard digital TV channels in the spectrum previously used by one analogue TV channel, using the most widely available technologies. The gain will be even more substantive if more advanced standards are being introduced (such as DVB-T2 for infrastructure and MPEG-4 for compression). The spectrum used to broadcast analogue TV, located between 200 MHz and 1 GHz, has very attractive propagation characteristics, and offers an optimal balance between transmission capacity and distance coverage. It is estimated that the value of electronic communications services that depend on radio spectrum in the EU currently exceeds €250 billion. Availability of radio spectrum is a clear enabler for economic and social growth. This illustrates why it is vital that the next opportunity to provide the much needed wireless bandwidth, the ‘digital dividend’, is managed as efficiently and effectively as possible to ensure the maximum benefit for all.

Dat blijkt uit metingen van TNO en uit een analyse van meerdere onderzoeken die door TNO is verricht. Het televisietoestel, andere consumentenelektronica en kabels bij mensen thuis blijken niet voldoende immuun voor straling van mobiele apparaten als smartphones en tablet PC’s. De maatschappelijke belangen van ICT komen daarmee in het gedrang.
