If the shielding distance of the intelligent shield is relatively short on site, the shielding distance of the signal shield is not ideal because the base stations around the shielding site are relatively close. Generally speaking, the shielding principle of a general intelligent shield is the power suppression of white noise, which means that the effect will be good if the power emitted by a device is large in this place. 

For example, if the signal strength transmitted by the mobile Signal Jammer in this frequency band covers the signal strength transmitted by the base station, it will show that the mobile signal in this frequency band will be shielded, otherwise, it will not be shielded. At this time, the high-power machine can be replaced. It is recommended that the model produced by Nanjing Bokang Electromechanical Technology Co., Ltd. is sma-818k90. This high-power signal shielding machine has a single channel output of 10-15w, and can also customize a certain operator frequency band with poor shielding effect.

Because the shielding distance of intelligent shield is closely related to the field environment and signal strength, the shielding distance is different in different places. Different operators' mobile phones have different shielding distances in the same field environment. This is because each frequency band of the equipment is output according to the maximum output power, which is generally 2-3W. However, in the same environment, the signal strength of the three operators can be divided into strong and weak, and the shielding distance affecting the signal shielding machine is related to the signal strength of the three operators' mobile phones.

The customer does not need any debugging after receiving the intelligent shield, but only needs to test the shielding effect after power on. Before the equipment leaves the factory, each frequency band has undergone strict debugging and aging. The goods can only be delivered after passing the test. After receiving the equipment, the customer does not need to carry out debugging. He can test the shielding distance through the mobile phone by simply connecting the 220V mains power.
