In areas where no wired transmission medium is available and where setting up a separate wireless network involves excessively high costs, data transmission via SMS using the GSM cellular network is a simple, reliable and cost-effective alternative.

A beverage vending machine shall serve as an exemplary area of application. The vending machine regularly checks the following:
the filling level of the coin box
the cooling system temperature.
any unauthorized opening of the front door

The vending machine reacts to certain events such as limit values being exceeded and informs the maintenance staff.
