Abstract

In accordance with a first aspect of the present disclosure, a control system for a radio frequency (RF) communication device is provided, the system comprising: a communication controller configured to control an RF communication of the RF communication device; a detector configured to detect the presence of an external communication device and to initiate a wake-up of the communication controller in dependence on said presence; wherein the detector is configured to detect said presence by detecting a first load on an RF interface of the RF communication device, said first load resulting from a first transmitted RF pulse; and wherein the detector is configured to initiate said wake-up if a difference between the first load and a reference load is above a high threshold, and to perform a presence verification if the difference between the first load and the reference load is between a low threshold and the high threshold. In accordance with further aspects of the present disclosure, a corresponding method for controlling a radio frequency (RF) communication device is conceived, and a corresponding computer program is provided.
