The project intends to investigate signal coexistence issues that will originate from the process of transition from analog to digital terrestrial television (switch-off) through which will be made available frequency resources that could be allocated to services different from broadcast ones. This is made also to meet the recommendations of the European Commission Decision 2010/267/EU on the harmonized technical conditions of use in the frequency band 790-862MHz for terrestrial systems capable of providing electronic communications services.

Specific attention addressed to modern communication technologies supporting mobile (LTE) and nomadic (Wi-Fi) services, whose future developments are expected towards new emerging standards such as the OFDMA (Orthogonal Frequency Division Multiple Access) and all-IP packet-oriented networks.

In this perspective, the project focusses on interference issues that can occur when the above mentioned signals are transmitted in different operating conditions (e.g. based on the mutual position of the base station, the radio user terminal and the front-end of the TV receiver).

To achieve these results hardware and software tools used in order to carry out simulations about the signal behavior of such mobile and nomadic technologies in the UHF frequency band. In this sense, it identifies the technical constraints of specific parameters (signal strength, guard band, protection distance, etc. ..) that must be respected to ensure the coexistence of these signals with DVB-T one, already operating in the same frequency band, in order to safeguard its correct reception on television sets as well as to investigate any useful counter-measure (filters, cross-polarization techniques, etc.) which can be adopted to mitigate theinterference effects.

The project carried out in collaboration with the ISCOM which provided appropriate human and material resources that integrated with those already made available by FUB.
