Westermo GW2028W-QFR-DC24 Industrial Cellular 4G LTE Router

  • DIN rail mounting
  • 3G, LTE, dual fibre
  • Quad Ethernet ports
  • RS232 and RS485 serial ports
  • Digital inputs for event detection
  • Relay contact options


The Virtual Access GW2028 router is a versatile, LTE wireless router suitable for a variety of industrial deployments. The compact and rugged structure makes it a suitable product for deployments where remote access to OT networks in harsh environments is required such as CCTV, telemetry, SCADA, smart grid, digital signage, and intelligent traffic systems. The product line supports AT 4G/LTE connectivity as well as legacy HSPA+, HSPA, UMTS, EDGE, GPRS, and GSM.

Quad Ethernet Ports

The GW2028 router offers 4 x 10/100 Mbps Ethernet interfaces. Ports can be fully segmented using VLAN and 802.1q.

Optional Dual Fibre GbE 

Dual fiber SFP GbE can be used in applications where a high degree of isolation is required, for example, an electricity substation or applications where distances of over 100m are required to connect to a host device. 

Digital Inputs and Output

Two digital inputs are provided that can be used to detect remote contact states for monitoring door open/close or PIR detectors or similar. Custom scripts can be written to determine the action to be taken on the detection of an input state change. Syslog events, SNMP traps or emails can be generated. There is also a relay contact output. This can be controlled by a script on detecting any event within the device, or it can be controlled remotely. 

Serial Ports

The RS232 serial and RS485 options facilitate direct connectivity to serial devices and enable remote console access. 

Connection Monitoring & Dual SIM

The connection monitor ensures the GW2028 router deliveries maximum availability so long as the cellular network is available. For critical applications a dual SIM architecture ensures that a backup LTE network can take over should the primary network fail. The GW2028 router detects a network problem and fails over to a standby SIM/APN.

SMS Commands 

The GW2028 router also supports SMS, so if the packet-switched side of the network is down you can still send commands to the router to perform diagnostics or even a reload.

Advanced Security and Routing Features 

The GW2028 router offers the highest level of VPN (IPSec and SSL) encryption and advanced routing features. The inbuilt stateful firewall offers the user compliance to IEC 62443 and IEC 62351 industrial cybersecurity standards.

Centralized Management and Zero Touch Deployment 

The GW2028 router benefits from Activator, Virtual Access' centralized configuration management, and monitoring system. Activator simplifies and automates deployment, management, and support tasks in managed network environments. The zero-touch deployment functionality built into Activator means GW2028 routers can be deployed without the need for onsite configuration or even knowledge of IP or LTE networks.
