With the transition from analogue to digital terrestrial television broadcasting more than one program may be located within one television channel. The consequence of this transition is the digital dividend as one of the most commonly used terms in the field of spectrum management in recent years. The digital dividend refers to the release of part of the spectrum allocated to terrestrial television in the UHF (Ultra High Frequency) band for other services. Due to the fact that broadband services over fiber optic communications systems are not available in all regions, broadband access via wireless systems is gaining importance for the delivery of Internet content. Identification of additional spectrum for mobile services continues to be of major interest to operators of communications systems and regulators in a number of countries. Estimates are that in the next ten years there will be a great demand for additional spectrum for wireless and mobile services, and the need is estimated at about 500 MHz. Given that the frequency spectrum is limited resource of any country, finding additional spectrum will inevitably involve the re-conversion of more of spectrum that is currently allocated to other services and systems. The option could be second digital dividend or further conversion of the UHF band, which now uses terrestrial television, for new mobile services. The political debate on the use of UHF spectrum are already under way in most countries and it is expected that at the World Radiocommunication Conference 2015 final decisions on second digital dividend will be done. In doing so, there are different opinions and views of the current user of that frequency band- television broadcasters and future user- mobile operators. Through the study and comparison of the use of radio frequency spectrum that was already released through the first digital dividend, as well as an analysis of necessary changes in the terrestrial broadcasting system, which would create the conditions for the further release of parts of the spectrum, an overview of the possible means of spectrum reuse is given.
