module functions

The Trainnet® OMG is an Onboard Mobile Gateway (OMG). It integrates multiple wireless communication capabilities such as 3G, LTE/4G, Wi-Fi and GNSS (GPS etc.) for IoT and train-to-wayside communications as well as for the reception of location and time information.

key features

The Trainnet® OMG is equipped with a 1 Gbit/s Ethernet interface for high speed communication with the train network and other compatible devices. A Micro-USB port is also available on the front panel for Firmware loading and maintenance operations.

The OMG module features three separate radios: LTE-A, WiFi and GNSS. All modules work independently.

The LTE-A Category 6 (3GPP Rel 12 LTE technology) component delivers max 300 Mbps downlink and max 50 Mbps uplink.

It also supports LTE/WCDMA Rx-diversity and 3G HSPA+ with max 42 Mbps downlink and 5.76 Mbps uplink.Our standard module works in EMEA, Australia and Brazil. The 3G/4G function requires a micro-SIM card to operate.

The GNSS supports simultaneously GPS and Glonass open service L1 (1575.42 MHz) reception with 33 tracking channels, 99 acquisition channels and 210 PRN channels. This module support short circuit protection and it is suitable for use with both active and passive antennas. It also supports anti-jamming, multi-tone active interface canceller function.

The Trainnet® OMG open platform runs on the Linux Operating System and supports Software development in C language. The OMG features a 800 MHz 64-bit ARM Cortex-A53 processor core.
