The rapid development of science and technology has brought a lot of convenience to people's lives, but it has also brought great challenges to the information security industry. Nowadays, many units are still using old cell phone signal blockers, and some customers have reported that the old models Jammers cannot block the latest 5G signals and need to be upgraded to the latest equipment. So how to choose new equipment? What are the characteristics of the new mobile phone signal jammer equipment?
Topsignaljammer mobile phone signal jammer reasonably blocks CDMA (China Telecom), GSM (China Mobile, China Unicom), SCDMA (Netcom and Telecom), DCS (1800MHz), PCS (1900MHz), PHS (Telecommunications Network PHS), 3G mobile phones Signals, 4G mobile phone signals, 24GWIFi, 5.8GWIFI, UHF, VHF wireless walkie-talkie signals and other mobile communication signals are connected to the base station according to electromagnetic waves, and information and sound effects are transmitted at a certain baud rate and modulation method.
This scanning speed can cause error code interference in the message format signal received by the mobile phone. The mobile phone cannot detect the normal data information transmitted from the base station, so that the mobile phone cannot establish a connection with the base station. The main symptoms of mobile phones include network search, no signal, and no service system.
Functional features of mobile phone signal jammer for sale:
