How Portable signal jammers Work
Many users of portable signal jammers do not understand its working principle, and often exceed the frequency range when using it, resulting in poor use effect.
The formation of mobile communication work is that within a specific frequency range, wireless devices (mobile phones, etc.) and base stations are connected through radio waves, and data and sound transmission is completed at a specific baud rate and specific modulation method. When the mobile phone communicates, it contacts the base station through the uplink frequency, and then transfers the signal to the mobile service exchange center to realize the call or data connection.
When the mobile phone is on standby, the mobile phone first sends a signal to the base station to register for the network, so that the mobile phone and the base station can get in touch. Once the mobile phone call demand is displayed, the mobile phone service channel is allocated to the mobile phone service according to the actual situation of the channel near the mobile phone through the request at the first time, so that the mobile phone jumps to the service channel to complete the call and data transmission. At the same time, wireless communication must be able to ensure that the signal-to-noise ratio is sufficient to complete reception and effective communication.
Therefore, when the portable signal jammer is at a certain transmission power, the field strength in the interference area affects the interference range. No matter how powerful the portable signal jammer is, as long as the transmission power is a fixed value, as the distance increases, the interference signal strength of the portable wifi signal jammer will gradually decay, thereby losing its interference ability. This is why the interference range of portable signal jammers is different in different signal field strength environments.
