The invention is directed to a signal-emission control device (100) for controlling emission of RF communication signals (Si) in a wireless communication network (140) that includes a transmitter device (152) and a receiver device (154). The emission is controllable with respect to a variable signal parameter (P). An emission-value ascertainment unit (102) is configured to ascertain variation-data indicative of an emission-value variation of signal-parameter values of the signal parameter. A scheduling unit (110) is configured to ascertain operation-trigger data indicative of operation conditions for triggering control of emission of the wireless RF communication signals in accordance with the ascertained emission-value. A transmitter-control unit (104) is configured to control operation of transmitter device for transmitting the communication signals (Si) according to the emission-value variation of the respective signal-parameter value upon fulfilment of the operation conditions. This enables an increase of the verisimilitude of the provided communication signals against illegitimate RF-based eavesdropping.
