The M2M Control Communication Hub is a “middleware” solution for the M2M Control Pro product line. The Communication Hub is a server application and allows uncomplicated communication between the controllers and (mostly server-based) software applications as well as between the controllers themselves via mobile radio (GPRS, UMTS, LTE, 5G). The communication is always encrypted and compressed. The functionality of the Communication Hub is based on the IP telemetry specification (DIN 43863-4). Support for the Communication Hub is an integral part of the firmware of all M2M Control Pro products.
