Measuring in a cellular telecommunication system the position of active mobile stations and the service, in terms of bit rate, they use. The first figure shows a number of users, four black dots having a voice connection with low bit rate and two users O having packet switched connection with a much higher bit rate. In the second figure the bit rate used is taken into consideration and, as shown by the greater area of the packet switched users, a more true picture of the traffic density is created. If the cell tends to get overloaded, requiring a cell split, the site X of a new base station will be shifted to the right comparing the second figure with the first.

Method and an apparatus for cell planning

A test transmitter for verifying the positioning of antennas in a mobile telecommunications system and a method for manufacturing such a test transmitter that is particularly suited for indoor use are presented. A mobile terminal is modified so that it can transmit in the downlink frequency band, and preferably so that it can transmit one or more of the signal types used for downlink signalling in the mobile telecommunications system.
