Title: Test transmitter, method and computer for testing a cellular mobile radio network

Abstract: It is known to introduce into a cellular mobile radio network (CN) a test transmitter (TS) which transmits a test signal for reception by mobile stations located in the coverage area of the mobile radio network. A simple, computer-aided method for testing the mobile radio network is disclosed in which the test transmitter (TS) transmits the test signal on a carrier already assigned to a base station (BTS) of the mobile radio network (CN) for transmitting broadcast signals. Thus, each mobile station can receive the test signal in a simple manner. The receive level is transmitted to the base station serving the area in which the mobile station is located, and then passed on to a computer for analysis. The computer uses a handoff procedure to analyze the receive level of the test signal and the receive levels of the broadcast signals, and then, based on the results, indicates whether the location of the test transmitter (TS) is suitable for installing a new base station to provide additional radio resources in the mobile radio network.
