Smart jammer, why can it interfere with your mobile phone signal?

Many users who use the Smart jammer do not know how it works and often use it beyond the frequency range, resulting in poor results.

The principle of mobile communication is that in a certain frequency range, the wireless devices (mobile phones, etc.) and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation. When a mobile phone communicates, it contacts the base station through the up-link frequency, and then transfers the signal to the Mobile Business Exchange Center to make the call. In standby state, the mobile phone contacts the base station through the broadcast control channel. Once there is a call demand, the smart shield first allocates to the mobile phone business channel by asking, according to the specific condition of the channel near the terminal, so that the mobile phone can jump to the business channel to achieve call and data transmission. At the same time, wireless communication must ensure sufficient signal-to-noise ratio to receive effectively and complete the communication.

Thus, within a certain transmission power, the interference range of the Smart jammer depends on the field strength in the interference area. No matter how large the Smart jammer is, as long as the transmission power is a fixed value, the interference signal strength of the smart shield will gradually decay with the increase of distance, thus losing the interference ability of the Smart jammer.
