Abstract
A cellular automated test set for testing cellular telephones consists of a RF interface coupled to an RF input/output of the cellular telephone and a transmitter-receiver coupled at an RF input/output of the transmitter-receiver to the RF interface. The transmitter-receiver transmits a first message signal to and receives a second message signal from the cellular telephone via the RF interface. The second message signal is generated by the cellular telephone in response to the first message signal. A data interface is coupled to a data port of the transmitter-receiver; and a processor is coupled to the data interface. The processor transmits a first data signal to and receives a second data signal from the transmitter-receiver via the data interface. The first message signal is generated in response to the first data signal and the second data signal is generated in response to the second message signal. In practice, the processor may be a personal computer system and the transmitter-receiver may be a modified cellular telephone programmed with a base station program.
