Racom MIDGE 3 - Industrial LPWA IoT Router

LTE Cat-M1, NB-IoT, LTE 450 MHz

4xGbE, 1xSFP, 1xRS232/485, 3xDI/O, IEC 61850-3

Version: MIDGE3-N-M (LTE 450MHz + Cat M1/NB-IoT)

MIDGE 3 from Racom is an industrial grade cellular router designed for demanding and mission-critical SCADA and telemetry applications - targeting sectors such as power and water utilities, oil & gas distribution and similar. It has been designed based on all relevant state-of-the art concepts to offer reliable 24/7/365 service, meeting both current and future market needs.

As such it offers a wide range of features for connectivity, protocol support, routing, troubleshooting, cyber security and management in combination with a highly robust hardware design certified for use in electrical substations (IEC 61850-3). 

For users of Racom RipEX 2 radios, the MIDGE 3 also offers a fully compatible feature set to allow for hybrid networks, as it is based on the same software platform. It has never been easier to build hybrid Cellular & VHF/UHF based private networks.

Model Specific

M!DGE3-N-M utilizes the Cinterion TX62-W-C chipset featuring european bands for LTE Cat M1 & LTE NB1 / NB2 in addition to 450 MHz bands 31 and 72.

In this configuration utilising the mPCIe expansion slot is not possible, meaning you cannot add extra serial ports using "Option C".
