Often there is customer service consultation and feedback, and mobile phone signal jammers are not effective. Why is the jamming installation not working or sometimes very ineffective? This is due to the surrounding environment in which the telephone signal jammer is used. Under what circumstances does the jammer's effect worsen?
Technically speaking, there are many reasons, but there are three reasons that are close to our average consumer.
1. There is a base station around or near the base station
2. There is a mobile phone signal amplifier or signal booster near your GPS jammer.
3. The walls around the jammer used, especially the reinforced concrete walls, are relatively thick. Low power machines are particularly inferior in their ability to penetrate walls.
