Our interfering radiation is lower than the national standard
To jam the phone, all you need is a device that broadcasts on the correct frequency. Although different cellular systems treat signals differently, all mobile phone networks use radio signals that can be interrupted. GSM used in digital and PCS cellular systems operates in the 900 MHz and 1800 MHz frequency bands in Europe and Asia and in the 1900 MHz (sometimes referred to as 1.9 GHz) frequency band in the United States. The jammer can broadcast on any frequency and is effective for AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. Old-fashioned analog phones are just as susceptible to interference as today's digital devices.
Effectively protect all types of cell phone signals, prevent communication between walkie talkie and receiver, and plug into various types of invisible wireless earphone intercom systems (including anti-shielding, earphone monitoring) can not work normally, only the mobile phone signals can be shielded, does not affect the normal operation of other electronic equipment. Is cell phone jammer radioactive and harmful to human body? Regarding radiation, as long as the size of the electronic device, there is radiation. Any electrical device generates radiation. As we usually use it in cell phones, we inevitably rely on radiation in our ears every day. Each country has established a radiation standard for cell phones. The radiation generated by our mobile phone wave jammer is lower than the national standard. We don't want to rely on our ears every day, so there is almost no harm to the human body.
In addition to the innovation of new mobile phone baseband chip technology and strong support of the operator's network system, today's smart phones can also achieve smooth internet access. , watch videos, remote voice and other functions. During a 2G network call, the 3G network can access the internet, and the 4G network can watch videos. With the continuous improvement of network formats, the functions of mobile telephony have also undergone revolutionary changes. Now, with the spread of 4G networks across the country, carriers and telecom operators have started actively allocating 5G in order to further expand the network format.
