Maintain the wireless communication must have enough SNR, so that can ensure the effective receiving of signal and finish communication. this jammer for mobile communication signal can destroy signal receiving condition for cell phone and cut off the connectioin between celll phone and base station by producing intercepting signal that can receive the same frequency with cell phone.

The power of jammer is limited in a certain range. The interception semidiameter of non hurdle space is decided by via attenuation and signal level of receiving base station. Covering semidiameter can be known by calculating out, outputting channel power, signal level of base station and gain of covering antenna.
