4. Functionality
The IAR-320+ functions as a multi-role industrial networking device that bridges wired, wireless, and cellular networks. It can operate as a standalone access point, a wireless bridge connecting two network segments, a repeater extending wireless coverage, or an AP client connecting to another access point.

In Access Point mode, it provides wireless connectivity to client devices such as laptops, tablets, or industrial controllers. In Bridge or Repeater mode, it extends existing wireless networks, improving coverage in large facilities or outdoor areas. The AP Client mode allows the device to connect to another AP, effectively integrating wired devices into a wireless network.

The integrated 3.5G cellular VPN router functionality enables secure remote access via mobile broadband networks. This is particularly useful for remote monitoring, SCADA systems, or mobile applications where wired infrastructure is unavailable. The VPN capability ensures encrypted communication channels, supporting secure data exchange between remote sites and central control systems.

The dual Ethernet ports allow flexible network segmentation or device interconnection, while the PoE input simplifies deployment by eliminating the need for separate power cabling. The relay alarm output can be configured to trigger alerts in case of network failure, power loss, or other critical events, enhancing system reliability and monitoring.
