In the past few years, various types of mobile cell phone jammer have emerged in an endless stream, and everyone is dazzled and dazzled, but in fact not all products are suitable for everyone to use themselves, some products are public, so not It is suitable for everyone to use in other fields. There is a very special mobile phone jammer, which often appears around everyone. Its name is mobile phone signal jammer. So what kind of advantages does this type of product have?
When we use a wireless signal jammer, you will find that no matter where you are, as long as you can turn on such a mobile phone jammer, then everyone has no way to search for your wireless signal. In other words, Household products are more effective than ordinary public products. In such an environment, you can always block all signals easily, but if you use a public blocker, it is likely to appear frequently. The shielding effect is unstable, so everyone needs to know the specific use effect.
Simply speaking, the frequency announced by the mobile phone signal jammer disturbs the frequency of the mobile phone to receive the base station. The jammer and the base station are destined to be a competitive connection. If the transmission power of the signal jammer is less than the channel transmitted by the base station to the mobile phone in the environment at that time If the power of the signal jammer is higher than the power of the base station to the mobile phone, the shielding device will not be able to shield it effectively. Therefore, any shielding device will show different shielding intervals when used in different signal environments, and China Mobile, China Unicom and China Telecom will be different, because the base station density, base station orientation and base station power built by these three operators cannot be the same. of.
