  • Patent number: 6085095
    Abstract: For determining the spatial distribution of the traffic volume within a radio cell of a cellular mobile radio communications network, a test signal transmitter is usually installed at a test location. Each mobile station which receives the test signal, measures and reports the receive level to a computer for evaluating the test location. The test location is deemed to be suitable for the installation of a new base station if the majority of the mobile stations receives a test signal of sufficient strength. In order to provide a simple method for determining the spatial distribution, it is proposed to first subdivide the radio cell (RC1) into several segments or sections (A1, A2, A3, . . . , D4) and to associated respective reference values (e.g. reference receive levels) with these segments or sections.
