M!DGE cellular routers, specially designed for SCADA & Telemetry mission critical applications, are well suited to many different wireless applications like POS, ATM, Lottery and Security/Surveillance applications.

M!DGE is Linux OS based and has been designed with attention to detail, performance, quality and reliability. All relevant state-of-the-art concepts have been carefully implemented.

M!DGE is well proven within the market since 2012 in thousands of industrial installations in tens of countries worldwide providing 24/7 reliable service.

M!DGE2, the 2nd generation of M!DGE with 2 SIM cards and 4 Ethernet ports, introduced in 2018, is the top equipment for SCADA communication if a cellular network is required.

M!DGE together with RACOM RipEX radio modems offers an unrivalled solution for combining Cellular and UHF/VHF licensed radio in a single hybrid network. Both provide the same customized serial SCADA protocols on COM interfaces.

Take the opportunity to remotely access and test a live M!DGE unit. Contact us for access details.


  • Switch / Router
    – M!DGE Ethernet ports can be configured either as Switch (one IP address) or Router (up to four physically separated ports with individual IP addresses). Any combination of switched/routered port is possible
  • Terminal server
    – 2 independent sessions
    – encapsulates serial protocol to TCP (UDP) and vice versa – suitable for IP and serial RTU’s combination within one network
  • Subnets
    – IP aliases – one additional IP address (alias) for each LAN and LAN/VPN combination possible
  • VLAN
    – 802.1Q – up to five VLANs can be assigned
    – M!DGE management can be done over VLAN
  • NAPT
    – masquerading, source and destination (IP/Mask/Port) translation supported
  • Virtual tunnels
    GRE – end-to-end tunneling protocol
    PPTP – basic encryption and authentication features, end-to-end
    IPsec – cryptographic end-to-end 
    OpenVPN – cryptographic single server to multiple clients
  • QoS
    – prioritize critical traffic (e.g. SCADA) over lower priority applications (e.g. management)
    – 802.1p and DiffServ (DSCP) supported
  • Static and dynamic routing
    – Static routing
    – Extended routing – policy based routing
    – Multipath routes – weighted IP session distribution for particular subnets across multiple interfaces
    – OSPF (Open Shortest Path First) protocol – allowing to be added to a network of OSPF routers
    – BGP (Border Gateway protocol) – peering with other BGP enabled routers
