METHOD AND APPARATUS FOR ESTIMATING FIELD STRENGTH |
摘要 |
<p>The invention relates to a method and an apparatus for calculating field strength in connection with buildings (102, 114) when an outdoor transmitter (106) is involved. To enable field strength determination preferably without heavy calculation procedures, the method comprises determining estimates of the electromagnetic field produced by the transmitter (106) on surfaces delimiting the building (104) or a part thereof, determining the field strength inside the building or a part thereof by means of the estimates of the electromagnetic field calculated for the surfaces delimiting the building or a part thereof. The method can be similarly applied when an indoor transmitter is involved.</p> |
