LANCOM 1790-4G+
Versatile connected via LTE-Advanced or external modems
This router offers you secure VPN functionality with maximum freedom of choice regarding the Internet lines available at the site: Thus, you realize reliable Internet access with additional LTE backup via the connection of any external modems. If, for example, you do not have a wired Internet connection on site, the router offers professional primary access via the LTE-Advanced cellular standard with up to 300 Mbps thanks to 4G.
Maximum availability
Ideal for business critical applications: The additional LTE-Advanced Modem (Cat. 7) for fast mobile phone access with up to 300 Mbps downstream is ideal for intelligent backup scenarios or as an alternative to wired Internet connections. With an upstream rate of up to 150 MBbps, the module offers high speed data transfer within the company network or to external cloud services.
Connects external modems
Der LANCOM 1790-4G+ ermöglicht den Anschluss eines externen Modems über die Gigabit Ethernet-Schnittstelle und bietet damit größtmögliche Unabhängigkeit bezüglich der Standort verfügbaren Internetleitungen.
Secure site connectivity via VPN
The LANCOM 1790-4G+ offers high levels of security. The standard equipment of 5 IPSec VPN channels guarantees strong encryption, secure connections for mobile employees, and protection of corporate data. The LANCOM VPN option upgrades the router to support 25 VPN channels. This ensures that your network is perfectly scalable and can grow on demand—without needing additional hardware.
Radically simplified configuration with SD-WAN
In combination with the LANCOM Management Cloud, the LANCOM 1790-4G+ paves the way to automated management. The software-defined WAN (SD-WAN) enables the automatic setup of secure VPN connections between sites, including network virtualization across the wide-area network: A few mouse clicks is all it takes to enable the VPN function and select the required VLANs for each site. The laborious configuration of individual tunnel endpoints is no longer required at all.
Stateful inspection firewall
Equipped with a stateful inspection firewall, the LANCOM 1790-4G+ protects the entire network. With features such as intrusion prevention and Denial-of-Service protection, this business VPN router provides optimal protection and secures all of the data on the network.
Advanced Routing & Forwarding
The LANCOM 1790-4G+ provides up to 16 securely isolated IP contexts, each of which has its own separate routing. This is an elegant way of operating IP applications with one central router and keeping the different communication channels securely separated from one another.
IoT-ready
The aim of the IoT (“Internet of Things”) is to capture information about physical “things”, mostly by wireless, and to make it accessible over the network. The integrated USB port of the LANCOM 1790-4G+ provides you with the basis of integrating modern IoT radio systems into your existing network infrastructure.
