Cobham Wireless has launched a new mobile tester designed to test railway GSM-R communications systems.
The new test solution from Cobham will assist railway network operators and suppliers of GSM-R radios and modems to validate the correct operation of GSM-R radios, both in the laboratory and in the field.
The Cobham Wireless 2201R is designed to connect directly to GSM-R device types including high-powered Class 2 radios. With the launch of Cobham Wireless 2201R, the company is replacing the previous-generation 4202R tester.
The 2201R provides accurate RF measurements and features including voice, data and SMS testing.
The new test solution features optional battery operation with up to 2.5 hours life. 2201R weighs 6.2 kg including the battery. The tester has handles at each corner, and the battery is located on the rear panel so that it can be unclipped for easy field replacement.
“The same Lector software that provides full access to all features when creating test scripts in the laboratory also enables the same scripts to be run, using the Autotest feature, in the locomotive cab,” said David Asquith, product manager at Cobham Wireless.
Cobham Wireless said 2201R features the simulation of group calls (VGCS) at various priority levels to verify the performance of cab, mobile radios, and peripherals such as optical and acoustical alarms to ensure proper performance of the radio system.
The 2201R allows voice group calls to and from the mobile to validate bi-directional communication. For the mobile originated call, the tester decodes the group ID and priority level while performing measurements.
The SMS function in the 2201R takes testing further by focusing on retrieving all the necessary parameters used by the phone for transferring messages that will help the technician to analyse faulty behaviour.
