Cell Phone Wifi Jammer Circuit

There is no way to prevent it. The shielding instrument is the so-called Cell Phone Wifi Jammer Circuit , which can shield all communication signals and cannot be prevented. cell phone jammer Effectively shield cdma (China Telecom), gsm (China Mobile, China Unicom), scdma (Netcom Da Lingtong), dcs (1800mhz), pcs (1900mhz), phs (telecom PHS), 3g mobile phone signal, wifi and 4g mobile phone signal Wait for all communication signals.

Cell Phone Wifi Jammer Circuit

The principle of mobile phone (radio communication) is as follows: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. In view of the above communication principle, the Cell Phone Wifi Jammer Circuit scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
