Prison Jammer Decrisption:
For the very important places as the prisons, the military and the some special government agencies protect the information from giving out is really important. In this condition blocking the signals of the mobile phones is really necessary and if you need one to used in such condition to cut the mobile signals this 250W High Power Cell Phone Signal Jammer here is really a good assistant.
The first advantage of this prison cell phone signal jammer is that it can block the 5 frequency bands CDMA GSM DCS GPS WIFI at the same time once turn on it. And the second advantage is that since owning 250W high output the jamming radius is of course powerful, the jamming radius of this 250W high power jammer is up to 600 meters according to the signal strength in the detailed place. In this case for the places where need to cut off the cell signals and owns a big area this mobile phone jammer is suitable and plays an important role in such condition. Thus as owning good design and cooling system, this 60W high power jammer supports continuously working.
Especially for prisons and other large sensitive locations such as military or governmental compounds. It can also use in Oil and Gas Storage Facilities and fields, Security Services, Military Units, Secret Services, Museums, Factory, Border Patrol and Drug Enforcement, Customs, etc. - Remote PC control with software to Turn each jammer, each band or the whole jammer system ON/OFF. Each unit offers a key lock support & mounting hardware
Moreover this high power jammer is environmentaly friendly and it will cause no harm to people’s health when you use it. Just by using it the 3G signals can be blocked without any difficulty.

Question and answers
1. The shell of jammer will become hot after working for some times. Does the long working time will damage the machine itself?
It is very normal. When designing, we are thinking of taking use of the conductivity of metal shell to help the heat sinking during our designation. By this way, the machine can be kept in good working condition for long time.
2. Is the jammer has the same effect to GSM cell phone and CDMA cell phone?
The capacity of anti-interference of CDMA is much better than GSM cell phone. So the interference effect for GSM cell phone is better than CDMA cell phone.
3. Is there any difference of distance between using jammer indoor and outdoor?
Yes. Generally speaking, outdoor signal is bigger than the indoor signal. Thereby, the shielding effect is worse outdoor. Strictly speaking, whether using indoor or outdoor, the effective distance of interference is related to the surrounding around, for example the distance between different base stations, positions of installation etc.
4. Does jammer interfere the other electronic equipment to work in normal condition?
No. Because the electromagnetic signal sent by jammer are totally used in the band that regulated by government and just have interception effect to cell phone communication.
5. Is jammer harmful to the human body and cell phone?
Please do not need to worry about it. The intensity of electromagnetic signal sent by jammer is in compliance with the national standard of environmental electromagnetic wave health. The signal sent by jammer is relatively small and unharmful to human body according to the testing result. Meanwhile, this device just damage the receiving condition to the cell phone and makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.
Prisons, Military, School, detention house or Government buildings, and other sensitive locations where the mobile phone signals are not allowed.
