Where do you use GSM communication in automation?

Field Network

Hi. I have application a bit far from the plant, and I don't know the best way to communicate with it. Would GSM work for me?

Expert’s answer : Where do you use GSM communication in automation?

Good question. First off, let’s explain this method of communication before we go into whether it would work for you.

Global system for mobile (GSM) communication uses time division multiple access (TDMA) and is widely deployed around the world. Developed in 1982 as a mobile communications standard, it provides international wireless communication in the 900-megahertz frequency band.

GSM architecture consists of a mobile station and a base station subsystem to make up a radio subsystem. Then you have the network, switching subsystem, and operation subsystem.

The mobile station consists of a device with a unique identity stored in a subscriber identity module (SIM). And the base station subsystem connects these devices with the network using wireless communication as the interface.

You also have more items in this architecture, such as a base transceiver station, base station controller, and network switching subsystem. We’ll go deeper into that at another time.

When you have a device outside the plant, and you just need to collect the process data, GSM should work well for you. Of course, you need to make sure you have a good signal in that location.

You can find devices with GSM communication built in, where you only need to add SIM cards. Or you can use gateways to collect device signals and then send them out using GSM communication.
