This is a professional Jammer, jams signal from GPS tracking and cell phones calling and gives you a silent private peace and time.

The Jammer can limit a 200meters area’s cell phones signal .Just take easy, it jams the signal only; do not have any other bad influence to cell phones. After power on, working voltage becomes stable in 3 seconds. In the next 30 seconds, all cell phones in the effective scope will be jammed. We know, there are specific baud rate and modulation system exist between cell phones and base stations, transfer the data via radio wave. The Jammer produces signal in a settled frequency band to jam the signal between cell phones and base stations, so that to achieve its aim. Signal bandwidth it can jam are , CDMA(851MHz-894MHz), CDMA(851MHz-894MHz), CDMA(851MHz-894MHz), PCS(1930MHz-1990MHz), 3G(2110MHz-2185MHz).Also ,you can refer to the affected cell phone standards , GSM, 3G, DCS, CDMA.

Why we still can see signal showed on the cell phones after the Jammer working? That is a false appearance, actually .Press any bottom; you can see there is no signal appears on cell phones. Does the Jammer will jam signal of other electronics productions except for cell phone? Jammer’s signal is settled to against cell phones in previous, and we know, electronics products have different working frequency band, Jammer can’t jam those signal. The weak Jammer electromagnetic signal will not cause harm to human body and cell phones. Does the Jammer have the same effect with CDMA and GSM cellphones? Well, this is a funny question .Performance of anti-jamming of CDMA is better than GSM cell phones .So, effective jamming scope of CDMA cell phone is small than GSM, it is about 2-4 meters .Attention, for some important places, we shall add the quantity of Jammer to ensure the effective on CDMA cell phones .Is there any difference between indoor and outdoor? Yeah, effective jamming scope indoor is 30-40 meters. But the scope can enlarge up to several hundred meters. Besides, the effective scope is depends on the distance and location.

Just like the said of title, the Jammer can jam GPS tracking too. Take the Jammer into your car, it forms an electromagnetic field to protect your track from GPS satellite tracking .Make sure those GPS products can’t receive and send signal.

Maybe those places need the jammer indeed:

Examination hall   prevent cheating

Oil station        prevent fire cause from microwave signal

Church           Keep silence

Hospital          prevent harm from cell phones for bodies and armaria

Military          prevent divulging secret
