Mostly, cell phones use one frequency to send signals and another frequency to receive signals. The frequencies used by major Telecom standards like GSM, CDMA, 3G/4G, DCS, PHS, etc are fixed, over large geographies. So, it is possible to create interference in cell phone communications (over a certain area) by transmittingRF signals that are in the same range as the cell phone communication signals, that need to be blocked.
To do this, one might need a small equipment (with transmitters, antennas and other electronic circuits) called as, ‘Cell phone Jammer’. When someone switches this equipment On, RF signals are generated and sent out (within a certain coverage area), causing interference with the genuine cellular voice/ data signals, effectively blocking/ disrupting them.
