What is the digital dividend and what is liberation?
The analog television has used to cast from the beginning of the second quarter of the twentieth century, part of the VHF frequency band (47-230 MHz) and part of the UHF band (470-862 MHz). The advent of digital technologies and new systems of data compression, reduced the number of frequencies necessary for the transmission of television, so that the spectrum needed to transmit analog television program, can be transmitted to 6 TV with digital technology equivalent quality. The migration from analogue to digital television was a more efficient use of radio spectrum is a valuable and scarce resource, and yielded a dividend in the form of new frequencies available, which is known as the Digital Dividend management.
To enable citizens to enjoy the digital dividend in the form of new mobile broadband services in fourth generation (4G), it is necessary to have a set of adjacent frequencies. In Europe it has been determined that this set of frequencies will be the 800 MHz band (790-862 MHz). In Spain, currently available frequencies for the dividend are scattered, and the frequency band of 800 MHz is occupied in part by some DTT channels (channels 61 to 69 UHF). The release of the Digital Dividend is the process of rearrangement frequency required for the 800 MHz band to become available in Europe. Once released frequencies, citizens can reap the benefits of the Digital Dividend.
