It should be noted that mobile jammers are related to general environmental conditions such as installation location. Therefore, the use of signal jammers considers this factor, so it will not protect blind spots and will not affect the shielding effect. Are jammers with wider signal range the same as jammers for GSM and CDMA mobile phones?
