Pocket Jammer

The device is designed to prevent cellular communication in designated areas.

Based on advanced cellular jamming technology, the jammer transmits RF signal,

which blocks the communication between the mobile phone and the cellular

base stations, thus paralyzing the operation of cell phones. This

neutralizes the threat of being tapped with the help of cell

phones, prevents illicit telephone conversations and

provides a silent work environment in a given area.

Blocking can be implemented both simultaneously and

selectively in the GSM 900MHz, 1800 MHz, 1900 MHz, UMTS 2100

MHz ranges providing flexible control and wider usage.

A unique design enables to use the product almost under any application

conditions: during confidential conversation in premises, cars, planes, etc.

Independent power control in each of 4 bands (3 dB in a step); easy to use.
