Those geographical areas that are not covered because the useful DTT signal is obstructed by the environment or it has a limited coverage by the network design can be called micro-TVWS. We assume that a DVB-T2 transmitter provides coverage for fixed rooftop reception as a primary service, to a building in which a LTE-A femtocell is installed indoors for local coverage, as a secondary service. The results have been obtained by laboratory emulation and validated through field measurements using professional equipment. Our results provide the technical restrictions of the LTE-A femtocell, mainly on the maximum allowable effective isotropic radiated power that could transmit on the DTT band in terms of carrier separation, from co-channel to adjacent band. These results meet the need of spectrum for IMT-Advanced technologies, so spectrum sharing is proposed in this paper as a new solution to make an efficient use of this resource.This work was supported in part by the Ministerio de Educacion y Ciencia, Spain, under Grant "DEFINE5G" TEC2014-60258-C2-1-R and Grant "ARCO5G" TEC2014-56469-REDT, and in part by the European FEDER Funds.Martínez Pinzón, G.; Cardona Marcet, N.; García Pardo, C.; Fornés Leal, A.; Ribadeneira-Ramírez, JA.
