Abstract
A modular system and process for obtaining measured data and forwarding them in a radio-based manner is based on a plurality of modules. The modules contain at least one device (31) for obtaining measured data, a device (32) for transmitting the measured data by radio, a device (33) for receiving data sent by other units, as well as device (34) for generating a transmissible code containing additional data, wherein the device (32) for transmitting the measured data and the device (33) for receiving data sent by other units together function as a repeater (35).
