Sagemcom GPRM1/HPRM1 Mobile Radio Modules

Designed for GSM-R cab radios to deliver mission-critical railway communications.

8W GPRS/EDGE Mobile Radio Modules (MRM) feature built-in radio blocking to filter out unwanted emissions from commercial cellular networks and a wide selection of interfaces. Fully-certified through Inter-Operability Tests (IOT) on GSM-R networks worldwide, their rugged design performs reliably in challenging mobile conditions and severe temperatures. The GPRM1/HPRM1 MRMs mount in standard 19”/482.6mm racks to reduce space and the need for additional cooling systems.
