Yes, a powerful Cell phone signal jammer can not only block mobile phone signals, but also effectively block Wi-Fi signals, GPS signals, and Beidou satellite signals. Wi-Fi and WLAN signals operate in the 2.4GHz or 5.8GHz range. If you need to block Wi-Fi signals, it is recommended to use a high-power signal jammer, such as the “JAMMERSIGNAL Electronics” SYT-G2100 portable 8-channel mobile phone signal jammer.
When the mobile phone signal jammer is working, it destroys the packet format signal received by the mobile phone through the scanning process. This interference prevents the mobile phone from establishing a connection with the base station. Common symptoms of mobile phones in the presence of a signal jammer include searching for the network, poor signal reception, and no service.
The portable mobile phone signal jammer uses imported ICs and is independently developed, which is particularly suitable for small places around the world that require security and information confidentiality. It can be used in customs, reception halls, mobile vehicles, mobile political and business circles and other places. This type of jammer is developed for specific mobile communication technologies in different countries. It can block GSM/CDMA/DCS/PHS/PCS/3G mobile phone signals within a range of 0.5-15 meters (generally covering 5-80 square meters). It can also block WiFi signals, GPS signals, Beidou satellite signals, and will not affect the operation of other electronic equipment in the surrounding environment. After the mobile phone leaves the shielding range, it can resume normal use.
