BH-201H series of cell phone signal jammers for all prohibit the use of mobile phones and need safe, quiet place-specific:
Fourth, the working principle
Block diagram of the work are as follows:
1, the slow-start after power --- shielding device, the power supply in 4 seconds from zero to stabilize.
2, the shielding --- start after 60 seconds the phone is within the scope screen.
As the interference signal jammers transmit power is limited (usually less than 2W), and the base station power is much greater than this value, so, from the base station closer, shielding the smaller the range.The minimum order of mobile phone jammer is 5 pieces. If you need a larger range of shielding should be equipped with two or more jammers.
