Universal wireless communication detector (UD-100) - preventing of high-tech cheating methods

In this paper the implementation of the device for wireless communication detection is presented. The system measures RF electromagnetic field strength for frequencies from 100 MHz up to 2.4 GHz and has wide range of adjustable sensitivity. Implemented device provides detection of cellular phone activities in all three main operating bands, and detection of other types of wireless communication such as radio communications, Bluetooth, Wi-Fi and so on. The device presents an improvement of a previous version of the detector MD-150. Measurement results are displayed on LED bar providing easy user readings and device operating. The system is battery powered, portable and can fit in any pocket.
