The “GWR-I352” is our “Proven” mobile industrial router, which was developed by its digital inputs and outputs for the remote control of machines via the mobile network. It is dust and splash-proof and is ideal for use in harsh environments. In addition to that, it has two SIM card slots for its failover option.

Product description

GWR-I352 is robust, high performance industrial cellular 3G router designed to meet the requirements of large number of machine-to-machine applications in harsh environments. Thanks to high speed 3G module integrated in the industrial router GWR-I352, all limitations in terms of possible applications are eliminated. No matter if GWR-I352 is used for providing a primary connection (ATMs, POSs, Sensors, IP cameras…) or backup solutions (remote offices, shops, petrol stations…), this product will demonstrate highest level of stability and reliability.
