Abstract: In this paper, we design and develop a low cost mobile phone detector which can detect active mobile phones near its vicinity. At the instant it detects radio frequency (RF) transmission signals from a mobile phone, the detector sounds a buzzer as well as blink a light emitting diode (LED) indicating that it has detected an activated cell phone in its vicinity. Using this detector, it is possible to detect mobile phones used for unethical conducts, e.g., cheating during exams in an examination hall. Since the detector works even when the phone is in silent mode, it can be used to find a lost cell phone. Furthermore, this detector has the ability to distinguish the number of mobile phones active in its vicinity. To compare our detector with commercially available detectors today our detector delivers almost the same amount of performance accuracy at a much lower cost.

Keywords: mobile phone detection; statistical signal processing; detection theory; RF detection.
