An Analysis on Effective Outdoor Mobile Phone Jamming Using Radio Frequency Channels

Abstract

This paper investigates the design and implementation of mobile phone jammers for GSM (900MHz AND 1800MHz) and 3G (2100MHz) for outdoor use in a high signal reception zone. A mobile phone jammer is a device that blocks reception of signals from a Base Transceiver Station (BTS) of a service provider to a Mobile Set (MS). Blocking is conventionally done by creating some form of interference at the same frequency ranges that MS use. As a result, an MS will either lose the signal or indicate non-availability of network coverage.
