It is expected that the upcoming DVB-NGH (Digital Video Broadcasting-Next Generation Handheld) shall be based on the existing DVB-T2 technology. Also DVB-NGH enabled Handheld receivers are going to work with the existing DVB infrastructure. In this paper we model the link budget deficits of the Handheld DVB receivers as additional power losses for a typical fixed roof-top DVB-T2 receiver. Because of those additional losses Handhelds get a reduced coverage. The attrition in coverage is especially dramatic for the indoor Handheld receivers. We analyze coverage for two different models of the Population density, .

Introduction The launch of DVB-T2 Digital Video Broadcasting - Terrestrial 2nd generation dates back close to 2002 after DVB-S2 DVB - Satellite 2nd generation . DVB-T2 was first deployed in 2009 in UK and by now has already penetrated in Italy Sweden Finland and even outside Europe like Zambia 13 . In countries where DVB-T services are already on air DVB-T2 is likely to co-exist with DVB-T. Compared to its predecessor DVB-T2 is capable of providing more new services. In November 2004 the ETSI European Telecommunications Standards Institute introduced DVB-H DVB-Handheld 5 . DVB-H could not become a success because of the lack of unification in the efforts of the broadcasters and Mobile Network operators. According to the design targets laid in 1 DVB-T2 would reuse the transmitters infrastructure of its predecessor system. Also it was supposed to provide services for both fixed and portable receivers such that it additionally provides a more robust version of the same service for
