The SmartFlex LTE router provides secure Internet connectivity for devices and LANs via cellular networks. It can be used to provide automatic wireless failover for wired networks, wireless connectivity for devices in remote locations where cable connections are impractical and wireless connectivity for mobile assets.


SmartFlex™ Description and Specifications

With upload speeds of up to 50 Mbit/s and download speeds of up to 100 Mbps, the SmartFlex™ provides ample bandwidth, even for applications that require video.

The SmartFlex is designed and manufactured for use in tough environmental conditions. Specifications include wide operating temperature ranges from -40 to +75 °C (-20 to +60 °C LTE450 module). It accepts input voltage ranges from 10 V DC to 60 V DC and is equipped with sleep mode for reducing electrical consumption.

The SmartFlex™ places intelligence out at the network edge with an extremely powerful Cortex A8 CPU at 1GHz, 256 MB flash memory, 512 MB RAM and 128kB M-RAM, providing full support for LTE speeds and applications. A secure Web interface allows users to configure and manage the SmartFlex from remote locations. The router can also upgrade its configuration and firmware from the operator’s central server, allowing for simultaneous mass reconfiguration of every router on the network. Users may insert Linux scripts and they can create multiple configurations for the same router. Users may switch from one configuration to another at any time.

The flexible SmartFlex™ can be configured to suit any application. The standard configuration includes 2 Ethernet ports with 2 independent LANs/IP addresses. The standard configuration also includes 1 USB host port, 1 microSD card holder, 2 SIM card holders for automatic failover to an alternate service provider, 2 binary inputs(I/O) , 1 binary output (I/O) and onboard GPS. An optional built-in WiFi module is also available, with industrial grade operating temperature ranges from -40 to +75 °C (-20 to +60 °C LTE450 module). Further optional boards available: 3x ETH (the router can be configured with up to 5 total Ethernet ports and 3 independent LANs/IP addresses) or ETH – RS232 – RS485 (isolation strength up to 2.5kV) or RS232 – RS485 (isolation strength up to 2.5kV) or RS232.

SmartFlex supports real time data encryption and the creation of VPN tunnels using IPsec, OpenVPN and L2TP. It supports DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS, and numerous other functions, as well as additional software like SmartCluster VPN Server and R-SeeNet.

About SmartWorxHub

SmartWorx Hub lets you manage all of your routers from a single location, wherever you may be. It places configuration, diagnostic and management functions and a complete view of your installed device population right on your desktop. SmartWorx Hub takes device management to new levels of flexibility and efficiency. Traveling to a site to diagnose a fault, change a configuration or download new applications and firmware is inefficient and a waste of money, especially when the job must be done in a remote location or during out of office hours. Even with remote access to individual devices, operations like firmware upgrades are time consuming and error prone if they must be repeated for each device. SmartWorx Hub eliminates these problems.

About SmartCluster

SmartCluster is a software designed to create a safe communications systems while using a public network – the Internet. SmartCluster is an OpenVPN server, which offers three functions for the creation of safe private networks in a public environment.
