Abstract
Some demonstrative embodiments include apparatuses, systems and/or methods of detecting an activity of a wireless communication device. For example, a Near Field Communication (NFC) device may include a transmitter to transmit information to a polling device by modulating a carrier signal emitted by the polling device; a sensor to sense a plurality of sensed modulation levels of the carrier signal; and a controller to detect an activity of an other NFC device based on the sensed modulation levels.
