ABSTRACT:
The invention relates to a method for planning radio coverage and for predicting the high-frequency received power level of a mobile radio transmitter in buildings for a number of floors above and below the floor in which the transmitter is positioned with a transmitting antenna. The method can be used for the most frequently existing building types, i.e. reinforced concrete framework buildings and masonry buildings. The invention is advantageous in that a complex series of measurements for planning the radio coverage in buildings can be forgone. In addition, no complex calculations using semi-emperical models, e.g. ray tracing methods, are necessary. The inventive method offers rapid adequately precise results concerning the radio coverage to be expected in a building and, at the same time, for a large number of floors.
