Almost everyone has a cell phone these days, the phone is ringing everywhere, and more and more people are tired of being interrupted by other people’s calls and are looking for a solution. The solution is a cell phone jammer. Cell phone jammers are used to temporarily interfere with cell phone signals within a certain range. It blocks the signal transmission between the cell phone and the base station. This is because cell phone jammers and cell phones work on the same frequency. But in order to keep cell phone signals from jamming, jammers should be regularly aligned with your cell phone. Once outside its interference range, the phone works fine.
Generally refers to indoor distance. In open outdoor areas, the effective range of cell phone jammers can reach hundreds of meters. Whether it is indoor or outdoor, the effective distance of shielding is the distance to the base station. The mobile phone signal jammer needs to pay attention that it is related to the general environmental conditions such as the installation location. Therefore, the use of signal jammers takes this factor into account, so that it does not shield dead corners and affects the shielding effect. Effective range Are wide signal range jammers the same as signal jammers on GSM and CDMA cell phones? No problem. Because the anti-jamming performance of CDMA mobile phones is much better than that of GSM mobile phones, the mobile phone signal jammer of CDMA mobile phone shielding distance is smaller than that of GSM mobile phones, but the difference is less than 2-4 meters. However, if necessary, it is necessary to add on-site mobile phones The number of signal jammers to ensure the shielding effect of CDMA mobile phones has attracted the attention of users in some particularly important places.
