Power control principle
Effective output power (channel power) and bigger interfere radius.
Only interfere downlink frequency of mobile system，without disturb normally working of Base Stations.
Slow start up design of circuit can maintain the stable operation condition with high integration.
Most of key components from US, Germany, Hungary and Japan.
controls adjustment of output power, power switcher, as well as kinds of alarms( over heating and VSWR) .
Each module can be adjustable power separately.
Warning standing wave indicator and warning temperature indicator separately.
Wireless communication is effectively completed by ensuring carrier signal density to a certain noise density during communicationA 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 throughThe below is given as 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:
Use omni-directional antenna the transmit antenna should be put in the middle of shielding area as below shown.
Use directional antenna, the transmission antenna should be put at the edges of shielding area
