Key Features

As a standard, this extra fast 4G LR77 v2 wireless router is equipped with one Ethernet 10/100, one USB Host port, one binary Input/output (I/O) port and one SIM card To save and backup communication data a version with 2 x SIM cards is available. The wide range of interface options of the 4G router further expands optional Port1 and Port2 selected by the customer – for Port1 is available Ethernet port 10/100, serial interface ports RS232/RS485/RS422/MBUS or (I/O - CNT). Port2 may be equipped with serial interfaces RS232/RS485/RS422/MBUS or (I/O - CNT). Another option is inserting of XC-SW board providing 3 x switched Ethernet 10/100 ports. This 4G wireless router is supplied either in a plastic or metal casing, based on the requirements of the customer.

Configuration is done via web interface protected by password. The 4G LTE router supports creation of VPN tunnels using technologies IPsec, OpenVPN and L2TP to ensure safe communication. Web interface provides detail statistics about the 4G router activities, signal strength, detailed log, etc. Cellular router supports functions: DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, HTTPS, SSH, OSPF, RIP, BGP control by SMS and many other functions.

Other diagnostic functions ensuring continuous communication include automatic inspection of PPP connection offering an automatic restart feature in case of connection losses or hardware watchdog which monitors the status of the router. With the help of a special window (start up script window) you may insert Linux scripts for various actions. For some applications the key feature is possibility to create several different configurations for one 4G LTE wireless router, the so-called profiles (maximum of 4), and the option to switch between them (for example via SMS, binary input status, etc.). Cellular LTE wireless router LR77 v2 supports automatic upgrade of configuration and firmware from server. This allows mass reconfiguration of many routers in one time. For 4G LR77 v2 wireless router is possible to develop user modules that modify LTE router behavior as requested by customer.
