Toughlink 2501

With Toughlink, Viprinet offers a new router platform that can cope with even the most extreme demands. Up to five broadband connections can be bonded to form a highly available connection. The extraordinarily robust housing enables mobile and stationary missions from the Sahara to the North Pole.

Toughlink offers a constantly updated range of standard configurations. However, it is also possible to have the routers configured individually for each customer. An optional additional housing cover makes the device waterproof. The Toughlink platform is more than just a router: In addition to the actual router firmware, certain editions will be able to run their own applications as virtual machines in parallel.

Toughlink model 2501 is equipped with four LTE modems that are optimally aligned to the frequency bands of Europe and America. The GPS function enables the current location of the router in the administration tool to be read out at any time, which is essential for efficient fleet or fleet management.  

The device is easy to handle. SIM cards can be changed very easily during operation, and the SIM card holders are designed as dual SIMs: Two SIM cards can be provided for each interface, between which the modem switches automatically. This simplifies cross-border use of the device, as it can be equipped with SIM cards from different mobile network operators even before the start of the journey to ensure fail-safe connectivity even across national borders. The device is therefore particularly suitable for use on the road and for all scenarios in which Internet must be quickly available, e. g. events or building site connectivity.

A Gigabit Ethernet interface provides the aggregated bandwidth to the LAN. At the same time, the two integrated WLAN access points with 2.4 or 5 GHz provide the available bandwidth without cables. Using the LAN interface, Toughlink can be supplied with power via PoE+. Therefore, if the device is mounted outside a building or vehicle, it only requires one single (Ethernet) cable to supply the interior.

All antenna connections are equipped with FAKRA connectors. These plugs allow simple “plug & play”, but are also self-closing and strain-relieved at the same time. With that, antennas can be installed or removed within seconds. In addition, the connectors enable optimal permanent installation.


  • Real bonding of all connection bandwidths
  • Quality of Service / traffic shaping
  • Monitoring (graphical and remote-syslog)
  • Traffic accounting via external server
