Industrial 5G Mobile Wireless Router


SCALANCE MUM856-1 is our first mobile wireless industrial 5G router. It provides simple and secure access to remote machinery via public 5G networks and allows you to tap into professional 5G applications for all industries.

Industrial 5G is here

Smart manufacturing, automated logistics, transparent supply chains or maintenance over the cloud: Industrial 5G will be the connectivity engine that drives secure, efficient IoT use cases. While not all 5G features are already available today in the 5G standard Release 15, the roadmap is set. SCALANCE MUM856-1 provides enhanced mobile broadband (eMBB) and supports easy and secure remote access use cases, delivering streamlined 5G connectivity today!


Powerful Performance for the next generation of wireless connectivity

The SCALANCE series is well-renowned for highest performance in tough industrial environments and with its rugged IP65 housing, SCALANCE MUM856-1 makes no difference. Adding 5G to industrial operations now becomes a worthwhile option. The built-in IPv6 support and the fallback to lower cellular standards (4G, 3G) whenever 5G connectivity is not available, makes SCALANCE MUM856-1 a truly secure investment that allows you get started with 5G right now!

From vision to reality: SCALANCE MUM856-1

In industry, in addition to the need for local wireless connectivity, there is an increasing need for remote access to remote machinery and equipment. In these cases, communication needs to bridge large distances. Public mobile networks can be used to access equipment located at a greater distance, for example in other countries. SCALANCE MUM856-1 in combination with the SINEMA Remote Connect management platform for VPN connections, allows easy and secure access to all remote assets, applications, or machines – even if they are integrated into other networks.

Zero Wires. One Unit. Massive Connections.

All connections onboard

Connections at scale: With high data rates (1 Gbps download and 500 Mbps upload) through 5G (Release 15), SCALANCE MUM856-1 is designed for the transmission of large data via public and private 5G networks.

  • 4x N-Connect antenna connectors
  • 1x Gbit Ethernet port with PoE (802.3 af)
  • Micro SIM slot
  • Digital input / digital output allows easy connections with I/O modules
  • Can connect to public and private 5G networks

Built for secure remote access

A perfect match: The combination of the VPN management platform SINEMA Remote Connect and SCALANCE MUM856-1 represents an ideal, complete, ready-to-go one-stop solution for remote access for remote maintenance via public networks:

  • Convenient central management of VPN connections via SINEMA Remote Connect
  • Easy integration of SCALANCE MUM856-1 in SINEMA Remote Connect via autoconfiguration
  • Integrated encryption and access mechanisms in SCALANCE MUM856-1 for uncompromised security
  • Supported security mechanisms: IPsec, OpenVPN, Firewall

Tough is better for brownfield

Made for industry: The robust SCALANCE MUM856-1 hardware with protection class IP65 with M12-Connect and N-Connect allows a cabinet-free installation and withstands demanding environmental conditions.

  • Withstands strong shocks and vibrations
  • Reliable performance in extended temperature ranges (-30 °C to +60 °C)
  • Redundant power supply 24 V DC
  • Diverse mounting options: wall, directly on stationary or mobile equipment, DIN rail mount
  • Form factor identical to SCALANCE Wi-Fi 6 client modules enable the switching of communication technologies without changing the design layout of the machines.

Built to out-perform

Start your transition to 5G with superior performance: SCALANCE MUM856-1 went through to serious test cycles with extreme overloads in order to identify design or material weaknesses. The resulting enhancements reliably ensure increased robustness for industrial environments. And since the Industrial 5G standard is rolled out in several release waves (with some industry-relevant 5G features still in the pipeline), SCALANCE MUM856-1 helps you gain traction in 5G without burning the bridge to proven cellular standards. Put simply: SCALANCE MUM856-1 is tailored to perform – in all respects.

  • Seamless fallback on 4G/3G where/when 5G is not – yet – available
  • Systematic testing of design and materials via the "Highly Accelerated Life Test" (HALT), which simulates an accelerated product life cycle through planned overloading

One router. One team. A lot of enthusiasm.
