Measured Interference of LTE Uplink Signals on DVB-T Channels

74--85

Because of the decision, taken during the ITU WRC-07, to allocate the upper part of the so-called digital dividend spectrum for mobile services on a co-primary basis with TV broadcast services, the involved stakeholders have a great interest in avoiding any interference caused by signals transmitted in adjacent bands. In this context the paper presents some experimental results of a study addressed to assess the effects produced by an interferential LTE signal transmitted from a user terminal when it is in proximity of a television antenna that receives DVB-T signals. The study has been conducted in the context of collaboration between Fondazione Ugo Bordoni and ISCTI, the scientic and technical body of the Italian Ministry of Economic Development, using high professional laboratory equipments and considering different experimental simulation test setups. Several simulation scenarios have been analyzed and results in terms of protection ratio and protection distance have been carried out.
