As
it was mentioned above cell
phone signal blocker perfectly
works with mobile phones. It blocks the GSM standard completely, which is using
two frequencies: 850/1900 MHz for
well as 900/1800 MHz for Europe and
mobile devices can operate not only those two frequencies. CDMA and 3G are also
a really popular data transmission standard for smartphones and other portable
gadgets. Jamming CDMA, 3G and GSM will not only give tranquility by blocking
the reception of jib-jabbers around you. It will also make you invisible for
modern tracking techniques such as cell tower triangulation.
