Deutsche Bahn, the largest railway operator in Germany, has selected the Willtek 4202R Mobile Service Tester as its radio frequency (RF) tester of choice to enhance the reliability of its railway communications network.

As one of the first railway networks to move to Global System for Mobile Communications for the Railways (GSM-R), Deutsche Bahn will use Willtek's technology to service and test GSM-R cab radios on all the operator's locomotives across Germany. The frame agreement to deploy the 4202R tester follows an initial purchase of 50 GSM service testers last year.
Benefits of the Willtek 4202R tester have been enhanced as it now offers a dc power supply option and will soon be available with a battery pack. This removes the need for unwieldy power supply equipment to test vital communications systems, making it a truly mobile tester.
Furthermore, the 4202R is the only network tester for GSM-R that can test both the radio frequency of cab radios as well as other in-cab equipment such as indicators and horns using the voice group call service (VGCS) that are triggered in the event of an emergency.
The 4202R is based on the Willtek 4202S Mobile Service Tester, a standard communication testset used by 60 per cent of service centres for the test, repair and alignment of mobile phones conforming to GSM worldwide. The 4202R version has the same features as the 4202S, qualifying it also for standard repair tasks. The voice group functions, in conjunction with the support of the special GSM-R frequency channels, provide additional benefits for railway applications and secure the railway safety measures introduced with GSM-R.
GSM-R is an enhancement of GSM (Global System for Mobile Communications) for railway purposes. GSM-R networks are currently being installed and tested. GSM-R is defined and supported by UIC project EIRENE together with ETSI Project Railway Telecommunications. UIC is the international union of railways; ETSI produces telecommunication standards for European and global use, such as GSM.
Willtek Communications GmbH provides test and measurement solutions to the wireless industry, including network operators, service providers, and manufacturers of mobile terminal equipment.
