4G LTE Router & Gateway

Technical description

SmartFlex SR305 is an industrial cellular router intended for the North American market
(NAM). This router is an ideal device for wireless communication in mobile networks that make
use of LTE, HSPA+, UMTS, EDGE or GPRS technology. Due to the high speed of data transfer
(up to 100 Mbps download and up to 50 Mbps upload) this router is 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 (ATMs) 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 added to the router at later date.
The router can be equipped with PoE PD (Power over Ethernet – Powered Device), which
allows the router to be powered via Ethernet. It can also be equipped with PoE PSE (Power
over Ethernet – Power Source Equipment), which enables the router to power other devices via
Ethernet. The SmartFlex can also be configured with a wide variety of port options. Options
include SWITCH – three switched Ethernet ports; RS232-RS485/422 – combination of serial
interfaces; RS232-RS485-ETH – combination of serial interfaces and an Ethernet port with
higher insulation. The router can be supplied in either plastic or metal casing, depending on
customer requirements.
