Here you can find your own jammer

Prior to assessing the effect of a mobile phone signal jammer on laptop Internet access, it is crucial to comprehend the interference frequency band utilized by the jammer and the frequency band employed by laptops to access the Internet.
First of all, if the interference frequency band of the mobile phone signal jammer overlaps with the frequency band used by the laptop to access the Internet, it will affect the laptop’s Internet access function. Let’s first take a look at the interference frequency band of cell phone jammers. Due to the wide signal coverage of domestic operators and the wide range of application standards, mobile phone signal jammers must achieve the effect of blocking the entire network. Generally, they will effectively block interference for 2G, 3G, 4G band signals, WiFi, GPS, and Bluetooth signals.
Having identified the frequency bands that the cell phone signal blocker described above can interfere with, let us now turn our attention to the frequency bands that laptops utilize for Internet connectivity.
Laptops generally have two ways to access the Internet, one is wired Internet access, that is, Ethernet network port Internet access, and the other is wireless Internet access. At present, mobile phone signal jamming device cannot block or interfere with wired Internet access, so here we mainly describe the frequency bands for laptop wireless Internet access. According to the current classification of laptops on the market, wireless Internet access supports single-band and dual-band. The so-called single-band refers to only supporting WiFi2.4 frequency band to connect to the Internet, while dual-band supports WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-band, and some that are more expensive or have more conscientious configurations will be equipped with dual-band Internet access.
The interplay between signal blockers and laptop computers' working frequency bands becomes apparent to keen observers, who can readily recognize the potential disruption of laptop Internet access by mobile phone signal jammers.
Detailed requirements are broken down into the following situations:
1.The mobile phone signal jammer does not have a WLAN module and will not affect the wireless Internet access of laptops;
