APPARATUS FOR DETECTING MOBILE PHONES, CAPABLE OF DETECTING THE USE OF ELECTRONIC APPLIANCES BY BEING INSTALLED AT CLASSROOM

摘要

PURPOSE: An apparatus for detecting mobile phones is provided to implement a detection process in a non-contact mode by combining a frequency counter, an electric field intensity meter, and a wideband antenna.;CONSTITUTION: An apparatus for detecting mobile phones is composed of a frequency counter(1), an electric field intensity meter(2), and a wideband antenna(3). The frequency counter measures a set frequency. The electric field intensity meter tracts the origin of the frequency by measuring the intensity of electric wave. The wideband antenna receives minute frequency.;COPYRIGHT KIPO 2011
