　　The cellular smartphone can't be linked, indicating that the mobile phone is in a essential kingdom. Generally, cell telephones with robust anti-interference and high sensitivity can have any such thing.

　　It depends at the neighborhood signal power. Where the sign is strong, the protecting distance of the sign blocker could be shortened, and the vulnerable sign will shield the gap farther.

　　If the mobile telephone is connected to the phone generally, it way that the defensive region has now not carried out powerful protective, and there may be leakage. If there may be no sign near the cell cellphone, it way that there is a base station or signal amplification at the location, and then it way that if the modern-day sign is shielded If the tool can not meet the on-web page defensive requirements, extra excessive-power device may be mounted.

　　All of these motives might also motive the mobile smartphone to have a sign after the usage of the signal blocker. We must make modifications and control the gap between the mobile cellphone and the cell cellphone whilst necessary.

　　The set up top of the cell telephone signal blocker should be on the same stage because the gadget you want to block;

　　Strong magnetic field and strong electromagnetic wave environment will have an effect on using interference;

　　When the smartphone is in a name, the jammer does now not sincerely block the signal;

　　Long-term use of the disturbance time will reason excessive heat and affect the disturbance radius;

　　To check the feature of the gps shield, please download the GPS sign detection software to test the protecting characteristic, or open the auto navigation feature test;
