摘要

In this paper, the required radiated power of a DVB-H gap filler for good indoor coverage at 514 MHz in different types of houses is determined. A new criterion for the electric-field value and carrier-to-interference-plus-noise ratio corresponding with good reception is proposed. Measurements in 14 different houses (detached houses, semidetached houses, terraced houses and apartments) and 121 rooms have been performed for three different radiated power levels. Indoor penetration of a DVB-H signal at 514 MHz is investigated for the different categories and a measurement methodology is proposed. Rooms have been categorized according to their location with respect to the gap filler (same room, adjacent rooms, non-adjacent rooms, other floors, and outdoor locations). It is shown that the distribution of the room penetration loss is lognormal. A comparison with existing models is made and a model for penetration through different floors is proposed.
