How long can the various signal communication distances in the LED display control system generally reach?

Abstract: The main communication methods of LED display control system are serial port, network port, USB, DVI, WIFI, etc. How long can the general communication distance of these signals reach? 


LED display control system main communication methods are serial port, network port, USB, DVI, WIFI, etc. How long can these signals generally reach the communication distance?

1 serial port:

Under normal conditions can reach 50 meters. Use a shielded good line to lower the baud rate. It is possible to reach 100 meters. It must be possible with electronic technology experience.

2 network port:

A single network cable generally does not exceed 100 meters. It uses relays such as switches and routers, or through the Internet. The theoretical communication distance is global (but it requires 2 terminals to communicate directly to the point-to-point. It must be well understood by the network)

3 USB:

Generally no more than 5 meters. Using a good shielded cable, it is possible to reach 10 meters in a non-interfering environment. It is possible to use a line with magnification to reach 20 meters.

4 DVI:

Under normal circumstances, the general DVI cable can only effectively transmit signals about 5 meters. If it exceeds 5 meters, the signal will be attenuated. If the shielding is good and the quality is good, then DVI will not appear in 15 meters. If the signal is lost, if it increases the signal attenuation, it is a gradual process, which is based on what you can accept.

5 WIFI:

In the open area, there is no obstruction between the antennas, and as high as possible, can reach a communication distance of 700 meters. If there is a barrier between the antennas, the communication distance will be reduced. The experience value is that the communication distance can reach 300 meters in a building.

Tips: WIFI transmission distance is affected by the ability of signal transmitting and receiving devices!
