Background

Digital signage, also called electronic signage, refers to display technologies such as LED, LCD, projection and e-paper monitors to vividly display digital images, video, web pages, weather data, restaurant menus, or text. Usually, digital signage screens are scattered in shopping malls, exhibition halls, airports, and outdoor areas. How to centrally manage and maintain those digital signages? How to publish and update content in real-time? Therefore, reliable and convenient connectivity is essential for content updating, management and maintenance across extensive digital signage

What role does WLINK 5G/4G Router in the whole system?

By integrating a WLINK 5G/4G industrial router, digital signage can be deployed in any location—without relying on traditional wired broadband connections. Once a SIM card is inserted, the router provides high-speed network access over 5G/4G. This enables administrators to remotely monitor the operational status of each digital sign and update content (such as images and video advertisements) in real time. Moreover, in emergency situations, the system can rapidly disseminate critical safety messages—like earthquake, typhoon, or rainstorm warnings—ensuring timely public alerts. The solution is further enhanced by the WLINK M2M management platform, which facilitates centralized management of both the routers and digital signage content updates.
