Racal Instruments and Radio Frequency Investigation (RFI) can now provide the cellular radio industry with a unique conformance test system for the new GSM Adaptive Multi Rate (AMR) system.

AMR is being introduced to increase the call carrying capacity of GSM.

The new Racal test system gives mobile handset designers a powerful tool to verify that the protocols used to control the AMR system are correct.

RFI will validate the tests according to the appropriate parts of the GSM 11.10 specification.

The Racal system, known as the Air Interface Monitor and Emulator or (AIME), verifies and confirms the correct coding of frames and the correct implementation of control procedures.

RFI's validation will rigorously test and assess compliance of the test scripts with the specification.

Greg Maton, Chief Operations Officer of Racal Instruments, said: "As a result of this agreement between Racal and RFI, GSM engineers will have a high integrity test system available to verify designs.

We are pleased to have contributed to the introduction of the new AMR system that will benefit us all by increasing call capacity".

RFI's Operations Manager for Mobile Communications, Colin Forester, added "As with all GSM functionality that may affect interoperability within networks there is a need to verify that AMR has been correctly implemented.

We hope to provide the industry with a conformance test platform in time for increased market demand for AMR".
