This project is mainly used to outdoor LED display, for example, the advertisement display. It solves the problem that when display is fixed at a high altitude, or some other places where it’s very hard to connect display and control system with wires. In this case, wireless technology is a good chioce.

As the fig shown, a computer communicates with the display through the WLAN router, and the computer must have a wireless networking card.

WLAN router adds a built-in access point function to a multi-port Ethernet router. This conbines multiple ethernet networks with wireless connetctions as well. A typical WLAN router includes four Ethernet ports, an 802.11 access point. This gives wireless users te same ability as wired users to send and receive packets our multiple network.

The displays are connected with a router by net cable, each display has a certain access port.Use the computer to configure the IP address for the displays, when transmitting the datas, select the right display through the corresponding IP address, and send the datas to it.
