Why are cell phone signal jammers not good in some places?
Mobile phone signal jammers interfere with the frequency band of mobile phones by transmitting the same frequency signal. To put it bluntly, it is electronic countermeasures. It depends on who has the most power and whose signal is strong. If there is a mobile phone tower near the area, then the mobile phone signal in the area is very strong. , it is difficult for the blocker to block the mobile phone signal in this area. The solution:
1. Use a digital shielding device, which is a shield that is not afraid of signal transmission towers nearby.
2. Increase the number of shielding device.
3. Use a high-power signal jammer instead.
