A communication device includes a main controller configured to control an RF communication of the communication device, and an antenna coupled to the main controller and driven by the main controller with modulated carrier signal. The communication device includes a detector coupled to the main controller and configured to detect a presence of an external communication device and to initiate a wake-up of the main controller in response to the detection. The communication device further includes one or more temperature sensors coupled to the detector and configured to detect temperature information of external or nearby circuits of the communication device. The detector is configured not to initiate the wake-up of the main controller if a difference between a first temperature measurement and a second temperature measurement is above a first temperature threshold or below a second temperature threshold.
