A signal jammer is a device that is widely used in school examination rooms, corporate conference rooms, and confidential places. It is a device that can block signals of specific frequencies and can effectively prevent network signal transmission and communication by mobile phones and communication equipment. However, some users may raise a question: Will using a signal jammer interfere with the normal use of WiFi?
First of all, it needs to be clear that a signal jammer can block the signal of any kind of communication device. The WiFi signal is a wireless signal in the 2.4GHz, 5.0GHz and 5.8GHz frequency bands. Therefore, in theory, signal jammers can block WiFi signals.
However, in the actual use of signal jammers, sometimes one chooses to shield signals within a specific frequency range instead of completely shielding all signals. Due to the different needs for using signal jammers in specific application scenarios, those who want to shield Frequency bands and signal types are also different.
Some high-end signal jammers are designed to block mobile phone signals alone, while protecting WiFi signals without blocking them. They usually use adjustable frequency technology, which can automatically adjust the blocked signal frequency band according to the needs of the user. They can block mobile phone signals alone, WiFi signals alone, or all of them. At this time, as long as the mobile phone signal blocking function is turned on alone, the normal transmission of WiFi signals can be ensured. Therefore, if you need to use a signal jammer to interfere with mobile phone signals, but do not want to affect the normal use of WiFi signals, you can get better results by choosing such a high-end signal jammer.
In general, differences in the design and production of signal jammers may affect the degree of interference they cause to WiFi signals. Therefore, when choosing to use a signal jammer, you need to make a choice based on the actual situation. If you need to protect the normal use of WiFi signals, you may wish to choose a professional-grade signal jammer.
