Mitigation techniques of the interference generated in TV distribution installations by 4G/5G signals in the 700 and 800 MHz bands

The activation in the UHF band of 4G/5G Base Stations can have in some areas an impact on TV reception, especially in case of community antenna installations. The adoption of proper interference mitigation techniques, such as the insertion of specifically designed filters at the head-end of the distribution network, allows to mimimise the effects in most situations.

Completed project

Assessment of the interference generated by the LTE signal on the head-end amplifiers of the TV reception systems

The presence of 800 MHz LTE signals within the UHF band traditionally used to distribute television signals may in some cases cause interference problems.

Completed project

Analysis of the interference generated by TV White Spaces on TV reception systems

The so-called “White Spaces” of the television band (TV White Spaces) represent free spectrum portions (locally and / or temporarily unused by users assigned to those frequencies) that can be used by secondary applications requiring reduced power, provided they do not generate interference with primary users.

Completed project

Vortex waves: possible applications for radio communications?

In recent years, the research community have shown interest in the study of some “non-conventional” properties of electromagnetic radiation in order to evaluate its possible application in the field of applied sciences.

Long term perspectives of DTT Convergence towards 5G: Applications of 3GPP Rel-14 to Italian scenarios

3GPP has defined in Release 14 the new eMBMS system, whose characteristics are well aligned to the technical requirements coming from the broadcast sector for TV services.
