IGW/936-L: Application Gateway/LTE Router

Wireless Application Gateway IGW/936-L with LTE Router

With the IGW/936-L, data from various sources can be received, read, processed and then forwarded wirelessly via LTE (Long Term Evolution) to various types of end devices.

Thanks to the high data rates of up to 100 MBit/s, applications with large amounts of data can be transmitted without problems.

The IGW/936-L can also send data prepared for visualization purposes directly to a display via the DVI/HDMI interface.

Here the integrated SSV/WebUI framework helps to adapt the data or the user interface to the respective end device (PC, smartphone, tablet etc.).

Since the framework exclusively uses standard web technologies such as HTTP(S), HTML, CSS, JavaScript and REST-based web services, there is no need to learn a proprietary programming language. Every professional web developer has the necessary know-how to customize the user interface with SSV/WebUI in the shortest possible time.

Software & Security

The IGW/936-L is equipped with the necessary software to develop and/or operate own web-based visualizations: Web server (lighttpd 1.4.26 with SSL support) and web browser (WebKitGTK+ with HTML5-, CSS3-, JavaScript support), (S)FTP-/TFTP server as well as an environment for Python, PHP and Java (JamVM 1.5.4, Classpath 0.98).

The SSV Field Data Engine (FDE), which is also included, takes care of collecting and distributing the data to be processed, whether via TCP, Modbus, OPC UA or other protocols.

The IGW/936-L with firewall, SSH, OpenVPN and OpenSSL (with SSL/TLS) guarantees a high level of data security.

For easy integration of the IGW/936-L, AutoIP and UPnP are also on board.

All software functions of the IGW/936-L can be easily configured with the SSV WebConfig tool.
