The design and construction of a dual-band mobile-phone jammer was thoughtfully carried out to sense phone network signals and to automatically activate it so as to de-activate the incoming or outgoing phone network signals. This jammer was designed to works at GSM 900mHz and GSM 1800mHz simultaneously and thus jams the four well-known network carriers in Nigeria (MTN, GLO, Etisalat and Zain.) as applied to lecture halls. It is evident from the results that the designed GSM jammer disabled mobile cell phone carriers.
