Measured interference of LTE uplink signals on DVB-T channels

Abstract

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 ba-sis with TV broadcast services, the involved stakeholders have a great interest in avoiding any interference caused by sig-nals transmitted in adjacent bands. In this context the paper presents some experimental results of a study addressed to assess the eggects 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 scientific and tech-nical body of the Italian Ministry of Economic Development, using high professional laboratory equipments and consider-ing dierent experimental simulation test setups. Several sim-ulation scenarios have been analyzed and results in terms of protection ratio and protection distance have been carried out.
