3. Router Description

LTE router LR77 v is used to wirelessly connect various equipments and devices via Eth-
ernet interface 10/100 to the Internet or Intranet. Thanks to high data transfer speed of up to
100 Mbps (download) and upload speed up to 50 Mbps it is an ideal wireless solution for traffic
and security camera systems, individual computers, LAN networks, automatic teller machines
(ATM) and other self-service terminals, etc. Routers LR77 v2B L45 are intended for use in
the 450 MHz band whose main advantage is the long range. The lower frequency, the less
transmitters are needed for covering.
As a standard, this LTE cellular 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 commu-
nication data a version with two SIM cards is available. The wide range of interface options
of the router further expands Port1 and Port2 expansion ports, which are selected by the cus-
tomer. For Port1 are available: Ethernet port 10/100, serial interface ports RS232, RS485,
RS422, MBUS or inputs/outputs (I/O – CNT). Port2 may be equipped with serial interfaces
RS232, RS485, RS422, MBUS, wireless interfaces WIFI or WMBUS, SDH expansion port or
inputs/outputs (I/O – CNT). Both of ports can be fitted with internal switch (exp. port SWITCH).
This 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 router supports cre-
ation of VPN tunnels using technologies IPsec, OpenVPN and L2TP to ensure safe commu-
nication. Web interface provides detail statistics about the router activities, signal strength,
detailed log, etc. Cellular router supports functions: DHCP, NAT, NAT-T, DynDNS, NTP, VRRP,
control by SMS and many other function.
Other diagnostic functions ensuring continuous communication include automatic inspec-
tion 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 ap-
plications the key option to create several different configurations for one 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.) is essential. Cellular routers LR77 v2 may automatically
upgrade configuration and firmware from server. This allows mass reconfiguration of many
routers in one time.
The router also supports additional software like R-SeeNet for permanent traffic monitoring
of routers or communication VPN server Digicluster.
