Room Cell Phone Jammer
The mobile phone signal jammer moves to the low-end wireless channel to the high-end scanner at a certain rate during the operation. The signal strength is in the order of several watts, and the shielding range is adjustable. Room Cell Phone Jammer is generally several tens of meters. The influence of the error code in the signal received by the mobile phone makes it impossible for the mobile phone to check the regular data information sent from the communication base station, and the mobile phone cannot establish a connection with the communication base station. Mainly manifested in the search network, poor mobile phone signal, no service system and other conditions. cell phone jammer Mobile phones with different working styles have different encoding methods or different deployment methods, and their data volume is different. According to the Shannon formula, the frequency stability regulations are also different, and the sensitivity regulations are also different.
Contemporary communication technology uses excellent anti-jamming technologies, such as frequency hopping, immediate code sequence spread spectrum communication (DSSS) and other technologies. However, the key to suppressing the influence of frequency hopping and spread spectrum communication is high frequency filtering, but it is because of the high frequency. Amplifiers and mixers are all discrete system components, which can cause intermodulation effects and noise malignant changes when they are strongly affected, that is, blockage of the RF front-end. In addition, there are many technical aspects of communication influences, such as broadband network noise influence, noise influence in some frequency bands, multi-tone influence, frequency deviation influence, tracking influence, and smart influence. Room Cell Phone Jammer It is only necessary to ensure that the shielding of the communication data signal is completed in a certain small area, so generally it is very easy to affect only the frequency range can be covered.
