I Want To Buy A Cell Phone Jammer
Since the mobile phone receives signals through the propagation of electromagnetic waves, the base station establishes a connection with the mobile phone by transmitting electric waves, so as to achieve the purpose of voice calls. Therefore, the interference of electromagnetic waves will have an adverse effect on the mobile phone. It is normal for the mobile phone to display a 4G signal and make a call to a 3G or 2G signal! It is not caused by cell phone failure or base station failure. The following explains why this phenomenon occurs: 4G has only one data channel (commonly called the Internet channel); 2G and 3G have two channels, data channel and voice channel. So 2G and 3G can surf the Internet and make calls, while 4G can only surf the Internet because it only has a data channel. In the early days of 4G, in order to satisfy the requirement that the mobile phone can make calls when using the 4G network, a solution called CSFB (Circuit Domain Fallback) was developed. 4G network fell back to 2G or 3G network and then began to make calls. But this technology has a disadvantage, that is, you can't access the Internet when making a call, so it is inconvenient for some business users. So when we buy some I Want To Buy A Cell Phone Jammer, we must know the rules and principles of the use of some signals. cell phone jammer It also uses the same frequency band and power as our signal to achieve a suppression effect, preventing us from surfing the Internet.
Now that 4G technology has matured, in order to satisfy mobile phone users with a better experience, VoLTE (High Definition Voice Call) technology has been developed that can use the 4G network to make calls while also being able to access the Internet. The mobile phone uses the data channel of the 4G network to make calls and surf the Internet, and the call quality is clearer than that of 2G and 3G. Dropped due to handover failure. Network operators use base stations to transmit wireless signals to serve users. The range of base stations is limited. Therefore, there may be many base stations in an area. Even if I Want To Buy A Cell Phone Jammer is used, it is difficult to shield the entire signal. . The combination of all base stations is a network system. Each base station has its own range. If this range is exceeded, the mobile phone must replace the base station to keep the mobile phone in the network at all times.
