The same effect of GSM mobile phone and CDMA mobile phone jammer mobile phone signal jammer? The problem is good. Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the signal interference of the shielding distance of CDMA mobile phones is smaller than that of GSM mobile phones, but the difference is about 20 to 40 meters. It’s not. However, if necessary, it is necessary to increase the number of signal jammers in the mobile phone to ensure the shielding effect of the radio jammer CDMA phone, which has attracted the attention of users in some particularly important places.

Today’s mobile phone signals exist in many places. All electrical equipment is surrounded by them. When not using the mobile phone, the impact of other electrical equipment is minimal. If there is no 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. With the use of mobile phones, data communication is carried out 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 jammers in gas stations. Taking the college entrance examination is an important part of this city. In order to prevent the canned college entrance examination, we will introduce a mobile jammer in the college entrance examination room. Mobile phone signal jammers can interfere with 3G mobile phone signals. In the civil service examination, cheating was republished by the press.
