More Info About Signal Jammer

Mobile Phone Signal Jammer - an instrument used to prevent cellular phones from receiving signals from or transmitting signals to base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected. Besides this, the jammer in this catalogue are compatible with Telephone Jammers, GPS Jammers, Bluetooth Jammers, Wifi Jammers, Spy camera Jammers, and Wireless Video Jammer, etc.

Jammers will not interference other electronic equipment to be in good working condition. 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.

Never worry about the bad effect to human body and cell phone by jammers. 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 no damage will appeared on human body according to the testing files. Meanwhile, this device is just damage the receiving condition to cell phone and makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.

Outdoors signals are bigger than the indoor signal. Thereby, the shielding effect is worse outdoor. In other words, whether using indoor or outdoor, the effective distance of interception is related to the surrounding environment as the distance between different base stations, positions of installation, etc. To GSM cell phone and CDMA cell phone, the capacity of anti-interference of CDMA is much better than GSM cell phone, while the interference effect for GSM cell phone is better than CDMA cell phone.

The working distance is the most concerned point for the buyers. Usually, the distance is 10 m to 1km. We have the basic type that support the typical coverage is 10 meters. For the professional Jammers, the working range on the highway is 1000m, while it is 500m in the center of city. The jammers are designed with metal shell for its conductivity can help the heat sinking. Thus, even long-time keeping in working condition will never damage the machine itself.
