As long as the mobile network is there our mobile phone wouldn’t stop communicating with the nearest cell (network station or tower) but when we receive a call, try to call for someone or connect to the internet our mobile receive a higher

frequency signal from the previous one that’s when we say our mobile phone is in active mode.

Mobile phone detectors are devices that that can detect active mobile phones around them by using antenna based detection system. As stated earlier when mobile phones are active there exist a radio frequency signal transmitted and received by the trans receiver and the mobile, thus mobile phone detectors detect are designed to detect this kind of signal by their antenna and use it as an input then give us an output weather by a speaker alarm, buzzer our any output device. They are mostly use for security purposes. During a test time or any place where using mobile phones are forbidden they can be used to detect any kind of cheating. In plane stations they also can be used test whether the device in the hand of the customer are mobile phone or not, for the sake of security.
