<p>The present invention relates to a method for calculating path loss PL at a point P in a coverage area CA of an antenna 4 at a cell site. The method comprises the steps: transmitting a signal from the antenna 4, the antenna having an effective antenna gain G<SUB>ant</SUB>, and measuring a received signal strength indicator RSSI of the transmitted signal by a receiving antenna at the point P. The method further comprises the steps: determining a dominant indirect radiation path between the antenna 4 and the receiving antenna to establish the effective antenna gain G<SUB>ant</SUB> from the antenna 4 in a direction of the dominant indirect radiation path, and calculating path loss PL at the point P using the established effective antenna gain G<SUB>ant</SUB> and measured received signal strength indicator RSSI. The invention also relates to a method for mapping a coverage area, a method for simulating changes in a communication network and a system for cell planning.</p> |
