ICR-3211
3. Router Description
ICR-3211 is an industrial cellular router intended for the market in Europe, Middle East and
Africa (EMEA) area as well as for the North American market (NAM). The ICR-3211 router
is designed for wireless communication in the mobile networks that make use of traditional
cellular technologies. The primary purpose of this router is its use in the Category M1 (Cat
M1) services on the cellular LTE network.
LTE Cat M1 is a new cellular technology specifically designed for the needs of applications
targeting the Internet of Things (IoT) or machine-to-machine (M2M) communications. LTE Cat
M1 is a low-power wide-area (LPWA) air interface that lets you connect IoT and M2M devices
with medium data rate requirements (375 kbps upload and download speeds in half duplex
mode).
The standard configuration includes two Ethernet 10/100 ports, serial line RS232, RS485,
one binary input and one output. The device also has two readers for 3 V and 1.8 V SIM
cards, which are located on the left panel of the router. The router can be provided only in a
metal casing.
The ICR-3211 router is equipped with a power backup feature. It is a short-term power
backup (maximum 15 seconds - depending on technology) which is used to complete the
running operation or to send the required data immediately after failure of power supply.
Configuration of the router may be done via a password-protected Web interface. Web in-
terface provides detailed statistics about the router’s activities, signal strength, detailed system
log etc. The router supports the creation of VPN tunnels using IPSec, OpenVPN and L2TP
to ensure safe communication. DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS,
backup primary connection and many other functions are supported.
The router provides diagnostic functions which include automatically monitoring the PPP
connection, automatic restart in case of connection losses, and a hardware watchdog that
monitors the router status. The user may insert Linux scripts which are started on various
actions. It is possible to create up to four different configurations for the same router. These
configurations can be switched whenever necessary via Web interface, SMS or binary input
status. The router can automatically upgrade its configuration and firmware from your central
server. This allows for mass reconfiguration of numerous routers at the same time.
The router also supports additional software like R-SeeNet for permanent traffic monitoring
of routers.
