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.
1. When the cell-phone jammer is working, why does a cell-phone signal indicator keep showing the signal?
It’s just a bad impression. In fact, the phone cannot communicate this time. After pressing the dial key, the signal indicator on the signal remains unchanged.
2. Will the cytostatic agent interfere with the work of other electronic devices?
Since the telephone signal sent by the electronic GPS jammer fully meets the international requirements of the mobile phone working frequency band, the communication of the mobile phone cannot be stopped. In addition, the signal is still relatively static and will not interfere with any other electronic product.
3. Are home jammers dangerous for people and mobile phones?
You can be sure. The signal strength of the electromagnetic signal of the cell phone signal jammer is very weak, and the test data will be displayed. The signal strength will not cause any harm to human body. At the same time, the mobile phone signal blocker can only block the input signal of the mobile phone, so that the mobile phone can not communicate with the base station and will not damage the mobile phone.
4. Is the distance between internal and external WLAN jammers of cell phones different?
Of course, the effective distance of the telephone signal jammer generally refers to the internal distance. Whether indoors or outdoors, the interference range of the effective shielding distance depends on the environment, such as the distance to the base station and the installation location.
