What are the precautions for buying frequency jammers?

  • 2022-07-24

The selected jamming device depends on the correct frequency signal. In order to prevent the mobile phone from receiving, the mobile phone jammer is used to block the cellular frequency. Now GSM, 2G, 3G and 4G LTE are used in new smart phones. The jammer can block it well according to its frequency band. The effective interference radius range of the frequency jammer is the influence distance, and the actual influence distance will change according to the signal strength, use position and electric quantity. Whether there is a good cooling system inside the interference device. If it does not have a built-in fan, it may damage the jammer. In addition, the potential overheating of the jammer will not only be harmful to its internal components, but also lead to its performance degradation.

In order to interfere with the new 5g mobile phone signal on the market, there are more and more frequency jammers. Now they are mainly to cut off the 5g signal. 5g jamming signal is mainly added to the equipment of frequency jammer. It can not only block 5g (LTE) and 5g (WiMAX) signals, but also block CDMA, GSM, DCS, 3G and 4G signals. It is a product with good performance. Secondly, you can choose the frequency band to block. If you don't want to block one or two frequency bands, you can turn them off and keep other frequency bands open. This requires considering whether the jammer interference frequency band has an independent switch, which can improve the use of jammers.
