Feature:

Created by advanced technology, this cell phone signal jammer stops the cell phone signals around completely. With this cell phone signal jammer, you won’t be disturbed by pesky phone signals. Especially when you are in the fields where phone using would lead to some explosions such as oil station, gas filled station, oil depot and so on.

This cell phone signal jammer also can be perfect for all those areas that require quietness and seriousness including meeting rooms, museums, theaters, churches, classrooms etc. Besides, made of high quality materials, we guarantee you the best quality of this cell phone signal jammer.

This device is designed to be placed either on a table top or inconspicuously on ceilings. Order one today and get yourself surprised!

Advantage:

Wireless communication is effectively completed by ensuring adequacy carrier signal density to a certain noise density during communication. A same frequency distortion signal is used to increase the ratio of carrier signal and noise (Nf) for shutting off the communication between the base station and mobile phone.

The output power of jammer is given, the shield radius in the situation of free space is confirmed according to the receiving signal lever from base station and free space attenuation in pass through. The below is given a formula of confirming

Shielding radius and a table of comparison of distance and pass through based on carrier receiving power from base station, output power of jammer as well as gain of antenna:
