Advantage:

Can control one or several LED Signs or LED displays from any computer with the software installed and connected to internet. It is not limited to distance. Can use Secure TCP/IP.

Disadvantage:

Internet connection needs to be provided in the sign location. Monthly connection fee is required If there is no internet connection available in the sign location. Internet connection in the sign location may need modem (ADSL or 4G) installation or cabling.

Mobile Data - GPRS Communication

This communication method is best for controlling outdoor or mobile electronic screens from far distance. For this type of communication, we use specific control cards with data SIM Card option. Similar internet communication method, controlling software communicates with the LED screen or LED display through internet connection. In the back-side, Content Management Software send the new descreen or settings to a could sever by using any type of internet connection. In the screen side, the screen downloads the new descreen from cloud sever using SIM Card mobile data (GPRS/3G/4G) and update the settings and information.LED Screen 3G Connection
