G227 - Wireless Network Board for 2 PCIe and 10 Micro-SIM Cards

The G227 is a rugged single slot CompactPCI Serial carrier board for up to three PCI Express Mini Cards. Two PCI Express Mini Card slots are by default equipped with two RP-SMA antenna connectors / cables each. Other types of antenna connectors are available on request. These slots can be used for UMTS, GSM, HSPA, LTE modems.

Fields of Application

The G227 provides connectivity solutions to cellular networks by adding LTE, UMTS, GSM or other types of wireless modems.

It is intended for use in various train connectivity applications including onboard WLAN, passenger infotainment and fleet management systems. In the train communication system architecture, the G227 is typically located at the front end where it communicates directly with a cellular network. To optimize the connection and network coverage, the G227 features ten microSIM card slots.


duagon provides a user friendly software tool designed for interacting with the G227. The user is able to remotely control which microSIM cards are connected to the modems. Remote power reset is also possible for each modem and the third optional PCI Express Mini Card module.

Suited for harsh and mobile environments

The G227 is designed for -40 to +85°C operating temperature and conformal coated in order to be used also in harsh and mobile environments. The final environmental qualification depends on the respective PCI Express Mini Cards used with the carrier.
