WiFi jammer is one of many signal jammers, designed to help people solve problems caused by mobile phones, radio signals and wireless connections. Each signal wifi jammer can operate in a specific frequency range, and WiFi jammers are no exception. The WiFi signal jammer has successfully blocked all wireless signals in the WiFi frequency range (2.4-2.5 GHz), thereby preventing unauthorized personnel from "leaching" confidential information.
