Aeroflex (Willtek) 4202R was developed specifically for railroad and public safety applications, which are based on the VGCS and GSM-R standards. This device can be used when checking the installed radio equipment in the driver's cab, as well as during the repair and final testing of GSM-R terminals.
The 4202R is powered by a rechargeable battery, making it truly mobile. These characteristics allow railway services to test not only GSM-R terminals, but also to test important peripheral devices such as indicators or sirens of incoming emergency calls.
