Progetto attivo dal 2018

Modeling and characterization of a GTEM cell

As part of a collaboration with Rai WAY, the electromagnetic behavior of an open GTEM cell at different operating frequencies (from 250 MHz to 1 GHz) has been analyzed, implementing an accurate finite-element model of the device. The analysis, conducted both from a simulation and an experimental point of view, has allowed to characterize this electromagnetic structure as to the field uniformity, a quality necessary to carry out field probes calibration or electromagnetic compliance tests.

Experimental activity

5G Broadcast demonstration during the European Championships 2018

Rai-CRITS experiments of feMBMS (3GPP Rel.14) in Aosta Valley

Rai-CRITS, in collaboration with the Technische Universität of Braunschweig (DE), is testing the most advanced precursor of 5G-broadcast technology, the feMBMS (Release 14 of the 3GPP standard). The technology was demonstrated in Valle d’Aosta during the European Championships, held in Glasgow and Berlin from 2 to 10 August 2018.

Active project

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.
