Mobile jammers can block malicious applications
3G is a symbol of 3G mobile communication technology, and 3G mobile communication technology is a cellular mobile communication technology that supports high-speed data transmission. 3G services can transmit voice and data at the same time at a rate of over hundreds of KBPS. Currently 3G has three standards: CDMA2000, WCDMA and TD-SCDMA. Itu has determined three wireless interface standards, namely CDMA2000 in the United States, WCDMA in Europe and TD-SCDMA in China. In 246 countries and regions, 538 WCDMA operators have opened WCDMA networks, and the 3g commercial market share exceeds 80%. The WCDMA backward-compatible GSM network has covered 184 countries around the world, and WCDMA users have exceeded 600 million.

If the portable mobile phone jammer has multiple antennas, the jamming signal will become stronger. There are several antennas. It plays an important role. Protect your personal life and career. High-power portable mobile phone signal dampers usually have a strong anti-interference ability. The wide interference radius and wide interference frequency type make it widely used. Different frequencies can be blocked simultaneously or separately. In addition to different high-power mobile phone jammers, there are also different applications, some of which are designed for bomb disposal and VIP protection and security protection in battle. Others are designed for police convoys, etc.
