ROUTER DESCRIPTION

Introduction
LTE LR77 v2 router is used to wirelessly connect various equipment and devices via Ethernet inter-
face 10/100 to the Internet or intranet. Thanks to high data transfer speed, up to 100 Mbit/s (down-
load) and upload speed up to 50 Mbit/s, it is an ideal wireless solution for traffic and security camera
systems, individual computers, LAN networks, automatic teller machines (ATM) and other self-ser-
vice terminals and machines. Routers LR77 v2 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 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 two SIM cards is available. The wide range of interface options of the router further ex-
pands an optional Port1 and Port2 – selected by the customer – for example Ethernet port 10/100,
serial interface ports RS232/RS485/RS422/MBUS or (I/O – CNT). For Port1 are available: Ethernet
port 10/100, serial interface ports RS232, RS485, RS422, or inputs/outputs (I/O ). Port2 may be
equipped with serial interfaces RS232, RS485, RS422, or inputs/outputs (I/O .

Configuration is done via web interface protected by password. The LR77 LTE router supports crea-
tion of VPN tunnels using technologies IPsec, OpenVPN, L2TP to ensure safe communication. The
Web interface provides detailed 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 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 (startup script
window) you may insert Linux scripts for various actions. For some applications 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 es-
sential. Cellular wireless routers may automatically upgrade configuration and firmware from
server. This allows mass reconfiguration of many routers in one time.
The router also supports additional software for permanent traffic monitoring of routers or commu-
nication VPN server Wie-Service24.
