Schildknecht AG, manufacturer of data radio systems, has been in business for over 30 years. Its core competences are safe and stable radio transmissions, such as those required in crane technology, water management, stage technology, as well as lift and cableway systems, for which automation is required. Worthy of special mention is the patented data preprocessing in the Industrial Wireless product series for the transmission of fieldbuses. Data preprocessing leads to stable preprocessing and thus prevents bus errors and standstills in the system. Since 2002, Schildknecht has been developing remote maintenance, telemetry and M2M solutions, working with customers to develop individual business models in the context of IoT and Industry 4.0. The basis for this is offered by mobile radio systems with globally deployable eSIM cards at a standard rate.
