In life, many people have some problems:What is a wifi blocker used for and how does it work?
Jammer-MartAugust 2022
Wifi signal jammer create a frequency that blocks Wi-Fi connections and prevents devices from "connecting to 3G, 4G, GPRS, or cordless Wi-Fi networks." GPS jammers block satellite frequencies. GPS jammers are less relevant to home security systems, but are often used to divert surveillance or espionage.
Each wireless technology works on a specific radio frequency spectrum, and they operate within certain noise margins and magnitudes. For example, cellular communications typically work at signal strengths up to -120dBm, so if someone is able to generate a high amplitude noise signal on that particular frequency, Wifi (-90dBm limit) and bluetooth work in the 2.4Ghz range if at that frequency In the presence of continuous (considering time division multiplexing) noise, the device will not be able to communicate.
