A time-domain recognition of different wireless technologies may be obtained using energy detection. In this paper, an energy detector was implemented using the Universal Software Radio Peripheral SDR platform. The energy detector output allows the formation of a packet presence/absence diagram. Experimental results indicate that the observation of Bluetooth packet exchange patterns reveals technology-specific MAC layer procedures, leading to the conclusion that technology recognition can be obtained on the basis of time domain technology-specific features.
