Relationship between frequency jammer and WiFi
If you want to make a frequency jammer, you can determine how many frequency bands to make based on the WiFi frequency distribution at the site. If the site requires the interference range of the frequency jammer to be relatively small, with a radius of about 10-20 meters, then you can use a low-power frequency jammer module, which can basically meet the requirements of on-site shielding. Of course, it also depends on the distance between the WiFi signal source and the frequency jammer. The closer the mobile phone or WiFi receiving device is to the shield, the better the interference effect will be. The closer the distance between the mobile phone or WiFi receiving device and the WiFi signal source, the worse the shielding effect will be than the same distance at the far end.
If the site requires the interference range of the frequency jammer to be relatively large, with a radius of about 20-100 meters, then you can use a medium-power frequency jammer module, which can basically meet the on-site shielding requirements. As for the interference distance, it is the same as the above-mentioned low-power principle.
If the interference radius of the on-site frequency jammer exceeds 100 meters, you can use a high-power frequency jammer module. The shielding distance is the same as the above-mentioned low-power shielding principle.
Use medium power or high power. One is conventional AC power supply, that is, the power supply of the frequency jammer should be connected to 220 AC power, and then the equipment is powered by the switching power supply. This method is more suitable for fixed places or places that need to be fixedly installed. Another method is to use battery power supply, which can be designed as an external battery or a built-in battery. The external battery is mainly used in medium-power mobile phone shielding, and the built-in battery is mainly used in high-power frequency jammers.
