4. The protective effect depends on the city's environment, using non-suburban effects, and the distance from the city and the high density of mobile towers in the suburbs, which causes the movement to transmit signals in the mobile jammer.
5. When used, the protection instruments around the antenna cannot have metal objects and protective walls between the protective instrument and the mobile phone
6. High magnetic field, the effect of motion on shielding effect in environment
7. Portable desktop and installation height of 1.5m to 1.8m, preferably in.
Between 8. The duration of protective equipment may affect the shielding effect due to fever
9. The strongest signal coverage is not easy for bluetooth interference signal (mobile phone call, the protection device is generally not easy to block during the opening period)
10.There are some delays in the signal cell phone grid on .
11. and it's possible that the cell phone is still being used to signal to the cell phone, but it's actually not used on the phone, please, a standard practical effect.
