Principle and application of wireless LED display screens

 The principle and application of wireless LED display screens

Users of led screen have to do a lot of work to update the LED displays contents due to numbers and pictures. In order to solve this problem, our factory has successfully researched and developed LED display screens control systems based on GPRS and GSM. It passes the built-in high-performance digital module to realize the remote and real-time control. In this way, users can solve problems by transmitting over a long distance and with one PC controls multiple LED display screens. The system consists of the led display with GSM digital module and the user data center. (Information management and control software and special delivery module)

Making efficiency reliable Transmission Control Protocol (TCP) based on features of GPRS communication so as to adjust packets transfer rates (Mbps) and use GPRS bandwidth effectively, average rates could reach to 15kbps.

Wireless LED display not only transmits text messages but also pictures and videos. Program software will process videos and pictures according to the screen’s size. We can use 3G router modem to support the fixed telecommunication networks and other services. A range of mobile terminal types will be encompassed, linking to terrestrial or satellite-based networks, and the terminals may be designed for mobile LED screens or fixed LED screens. The wireless 3G system LED control card will auto connect to the Led Editor service center running in remote PC-console through domain name parameter so as to building up a communication link.
