3. Router Description

SmartFlex SR309 is an industrial cellular router intended for the South Korean markets

(SKT carrier only). This router is an ideal device for wireless communication in mobile net-

works that make use of LTE, HSPA+, UMTS, EDGE or GPRS technology. Due to the high

speed of data transfer up to 150 Mbps (download) and up to 50 Mbps (upload) is this router an

ideal solution for specialized M2M devices and IoT as well as for wireless connection of trafﬁc

and security camera systems, individual computers, LAN networks, automatic teller machines

(ATM) and other self-service terminals.

The standard conﬁguration includes two Ethernet 10/100 ports, one USB 2.0 Host port,

two binary inputs and one output (I/O connector). The device also has two readers for 3 V and

1.8 V SIM cards, which are located on the rear panel of the router. The router also includes

a microSD card port that supports up to 64 GB card storage (32 GB in the case of SDHC

cards). The router can be equipped with a WiFi module, but this must be part of the initial

conﬁguration – it cannot be assembled to the router at some point in the future.

The router can be equipped with PoE PSE (Power over Ethernet – Power Source Equip-

ment), which lets the router to power other devices via Ethernet. The SmartFlex router can

also be conﬁgured with a wide variety of port options. These can be SWITCH – three switched

Ethernet ports; RS232-RS485/422 – combination of serial interfaces. The router can be pro-

vided only in a metal casing.

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.
