Cell phone jammer or disabler is a device that transmit pulsing signal at the frequency the cell phone is receiving. The signal pulses  disturb the down link signal from the base station randomly. The net result is forming a sequence of data that can not be decoded properly by the base band circuit of the cell phone.

In the case that a conversation has already started before the jammer is turned on, the jamming signal will destruct the data to a degree that the voice decoder will cease function. The cell phone user can not hear any voice or receive any meaningful message.

This is a medium power jammer designed to provide the user a dome of silence when needed. Inside this dome, the user can block out any cell phone intrusion. The power is properly adjusted so the jamming distance enough for personal protection.

In many countries, jammer is allowed only for public safety applications such as prison, court house, police car, remote bomb defusing, exam room...

Buyer should check the local ordinance before purchasing.
