Product Overview

The GQIR02N-4G is an industrial‑grade IoT wireless router that leverages full‑network compatibility and 4G/3G/2.5G cellular networks to deliver high‑speed wireless connectivity, making it the preferred choice for fast, large‑data‑volume transmission of video, images, and other high‑bandwidth content. It comes standard with I/O ports and an Ethernet port (which can be omitted), and supports 4G‑to‑Wi‑Fi conversion, enabling seamless aggregation and network access for a wide range of serial‑port, Ethernet‑enabled, and Wi‑Fi devices on site. Simply power it on to establish a network, quickly and conveniently connecting remote devices across various locations to a central management hub. It is widely deployed in applications such as remote data acquisition, remote equipment monitoring, remote control, and remote alarm systems. Its advantages are particularly pronounced in scenarios involving high‑volume remote data transmission, including forest fire prevention, video surveillance of pollution sources, water‑source monitoring, image capture at reservoirs, and traffic‑checkpoint imaging.

It is suitable for industrial automation applications such as road traffic control, rail transit, power‑grid automation, coal‑mine automation, wind energy and wind power, metallurgical steel plants, oil and gas operations, building automation systems, oilfield automation, hydropower plant automation, data‑center monitoring, water‑resources monitoring, environmental‑protection monitoring, urban underground utility tunnels, and other industrial‑control environments that demand high‑performance, highly reliable networking.

 

Product Features

◆ Standard configuration includes one LAN port and one WAN port; supports RS485 and RS232 data transmission via terminal interfaces, meeting the networking requirements of various on-site port‑type devices.
