Today’s mobile phone signals exist in many places. All electrical equipment is surrounded by them. When the mobile phone is not in use, the impact of other electrical equipment is minimal. If you do not have a mobile phone, there is no data communication between the mobile phone and the base station. It will not change the sudden signal. This is a relatively stable electromagnetic field. This static electricity hardly interferes with electronic equipment. In the use of mobile phones, there is data communication between the mobile phone and the base station, and a sudden change signal appears, thereby forming a dynamic electromagnetic field. Dynamic electromagnetic signals can affect the failure of electrical equipment. This is the importance of using mobile cell phone jammer in gas stations.
Adjustable cell phone jammers are very popular. It can block four signal bandwidths: GPS, CDMA, GSM and DCS. It is also built into a rechargeable lithium-ion battery. The effective blocking radius is 2-15m. Easy to operate. And the price is very cheap. It is also useful for conferences and important business events. It has excellent interference capabilities. There are optional interference settings. The phone cannot make or receive calls within the blocked range.
