The GWR-352WV is our “Specialist”. This router has been developed for applications requiring a power supply of 9 to 36 VDC. It has a USB 2.0 port, an Ehternet and an RS-232 interface. In addition, it is equipped with two SIM card slots with a failover option.

Product description

Wide Voltage GWR Router Series is designed to provide remote connectivity over cellular networks especially for customers who require a power supply from 9 to 36 VDC. Low transmission delay and very high data rates offered by existing cellular networks completely eliminate the need for expensive wired infrastructure. GWR series brings scalability of even most demanding corporate networks to the highest possible level. Installing a reliable, high performance backup solution for existing land lines or satellite networks is now a simple task thanks to modern cellular networks. Therefore, no matter if the goal is to provide primary internet access or backup solution for already existing network GWR router series represents a top rated solution.
