How to Control the LED Screen Wirelessly

How to control the LED screen wirelessly
In response to the development of the times, mobile phones and ipads now have more and more functions of computers, that is, online office can be realized on mobile phones and ipads. Since mobile phones and Ipads can realize most of the functions of computers, it is not a problem to use mobile phones and ipads to control the LED display.
In fact, one of the important reasons why mobile phones and ipads control LED displays is to connect these devices, and only need to use WIFI to connect.
How to control led display with mobile phone and ipad
1. WIFI wireless control
The system uses the mobile terminal (mobile phone, IPAD) as the control terminal, and realizes the remote wireless control screen for the first time. All its functions can be realized by the touch screen control, and the zero-second switching will not be stuck. Really abandon the traditional keyboard, mouse, software instead of hardware.
Working principle: By adding a wireless router or other wireless devices, bridging with the user's original wireless network, building a wireless local area network, and easily integrating the network control card into the wireless network for wireless network control.
Features: No wiring, easy installation and debugging, fast data transmission.
Required equipment: network bridge, wireless router (the application on the display screen is to choose a device that can change the antenna, so that the wireless signal can be effectively received).
If the area where your display is located already has wireless signal coverage, it is even simpler. You only need to bridge the wireless router connected to the LED display control card in the led display to your wireless network, and then you can use the internal network. Control the display from any computer.
2. RF wireless control
Working principle: One end of the RF module is connected to the control computer, and the other end is connected to the serial port of the control card. After the driver is installed on the computer, a virtual serial port is generated, and data is sent through this serial port.
3. GPRS wireless control
Working principle: After the GPRS module is powered on, it completes the process of dial-up Internet access and connects to the data center server. The client accesses the server through the client software, and the server forwards the information.
4. 4G full Netcom wireless control
Working principle: basically the same as 3G/GPRS.
Features: 4G full Netcom, fast transmission rate, fully realized real-time control, sending commands can instantly respond to relevant control.
