GWR-I Industrial Cellular Router Series


GWR-I high speed industrial cellular router series represents a group of industrial graded routers especially designed for expansion of existing industrial networks, remote telemetry and data acquisition in harsh environments. Low transmission delay and very high data rates (up to 100 Mbps) offered by existing cellular networks completely eliminate the need for very complex installation of wired infrastructure in industrial environments.

GWR-I router comes with versatile connectivity options such as 3G/4G, ADSL2+, up to 5 Ethernet ports, RS-232 and RS-485 ports, 3 digital inputs and 3 digital outputs. The device is equipped with LCD display which makes possible to monitor router’s status and detect a possible problem without need to access it via PC.

Complete series is based on reliable and high performance hardware platform using ARM Cortex-A8 microprocessor. All router models have dual SIM card support. The form factor of the router is adjusted to industrial environments and DIN rail mounting kit is part of standard equipment for GWR-I series. With a robust all-metal case and top quality components inside, durability of the product is guaranteed.


  • Dual SIM card support
  • The whole set of advanced WAN settings
  • VPN (GRE, IPsec and OpenVPN) tunnel support
  • With Serial-to-IP feature it is possible to connect, control and perform data acquisition from almost any device with serial RS-485 or RDS-232 port.
  • Galvanic isolation on all ports (except USB OTG serial port)
  • Web interface, CLI, detailed log, SMS control feature, SMS of GPIO input, partial and full configuration Export/Import
  • Chroot environment
