When choosing and using a mobile phone jammer, people often encounter a slight gap between the interference distance and the expected one. They always want to have a larger interference distance, or use a device that can interfere with the entire building or factory area, and so on.

From the user's perspective, this idea is understandable. Users also understand that the greater the power of the mobile phone jammer, the greater the interference range will follow, which is indeed true in theory. Here, I would like to say that in different places of use, it is not necessary to blindly increase the transmission power of the mobile phone jammer to achieve a completely dead angle free interference effect. It is necessary to consider many factors based on the actual situation before deciding whether to increase the transmission power of the jammer. It is best to listen carefully to professional advice.

If the user has the following conditions on site, they can choose a high-power mobile phone jammer.
1. The use site is a large indoor and transparent environment, such as a factory building. The factory building has a relatively high floor height compared to other buildings, so high-power jammers can be selected to solve the problem of mobile phone signal coverage throughout the factory building, regardless of whether omnidirectional or directional antennas are used.
2. The use site is an outdoor environment, and the outdoor mobile phone signal is generally stronger than the indoor one. Therefore, it is reasonable to use high-power jammers to solve the problem of mobile phone signal coverage in the outdoor environment.
3. Users do not consider budget issues. As we all know, the cost of mobile phone jammers also increases as the transmission power increases. When the power of the jammer is doubled, the cost often increases by 5-10 times, or higher. Therefore, if users do not consider the budget, they can also choose high-power jammers.
