Chapter 1 Product Introduction
1.1 Overview
Ursalink UR32 is an industrial cellular router with embedded intelligent software features that are
designed for multifarious M2M/IoT applications. Supporting global WCDMA and 4G LTE, UR32 provides
drop-in connectivity for operators and makes a giant leap in maximizing uptime.
Adopting high-performance and low-power consumption industrial grade CPU and wireless module, the
UR32 is capable of providing wire-speed network with low power consumption and ultra-small package to
ensure the extremely safe and reliable connection to the wireless network.
Meanwhile, the UR32 also supports Fast Ethernet ports, serial port (RS232) and I/O (input/output), which
enables you to scale up M2M application combining data and video in limited time and budget.
The UR32 is particularly ideal for smart grid, digital media installations, industrial automation, telemetry
equipment, medical device, digital factory, finance, payment device, environment protection, water
conservancy and so on.
For details of hardware and installation, please check UR32 Quick Start Guide.
