Chapter 1 Product Introduction
1.1 Overview
Ursalink UR52/UR55 is an industrial cellular router with embedded intelligent software features that are
designed for multifarious M2M/IoT applications. Supporting global WCDMA and 4G LTE, UR52/UR55
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
UR52/UR55 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 UR52/UR55 also supports Fast Ethernet ports, serial port (RS232/RS485) and I/O
(input/output), which enables you to scale up M2M application combining data and video in limited time
and budget.
The UR52/UR55 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.
