Cell phone signal blocker basics

To jam a phone, all you need is a device that broadcasts on the correct frequency. Although different cellular systems handle signals differently, all cell phone networks use radio signals that can be interrupted. GSM for digital and PCS cellular fragmentation operates in the 900 MHz and 1800 MHz bands in Europe and Asia, and in the 1900 MHz (sometimes called 1.9 GHz) band in the United States. Jammers can be broadcast on any frequency and are valid for AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. Older analog phones are just as susceptible to jamming as today's digital devices.

1. Why does the phone signal indicator constantly show a signal when the phone jammer is working?

This is just a bad impression. In fact, this time the phone is unable to communicate. After pressing the dial button, the signal indicator on the signal remains unchanged.

2、Does the cell inhibitor disturb the work of other electronic devices?

As the electronic GPS jammer retrieves the phone signal perfectly in line with the international requirements of the cell phone task band, thus the phone's communication can not be suspended. In addition, the signal is still relatively static and will not disturb any other electronic products.

3. Is there any risk to people and cell phones from home jammers?

You can be sure. Wifi blocker app electromagnetic signal signal strength is very weak, will display test data. The signal strength will not form any damage to the human body. At the same time, the cell phone signal blocker can only block the output signal of the cell phone, so that the cell phone can not communicate with the base station, and will not damage the cell phone.

4. Can the interval between the external and internal WLAN jammers of the phone be different?

Of course, the effective interval of the phone signal blocker generally refers to the external interval. Whether indoors or outdoors, the range of interference of the effective shielding interval depends on the environment, such as the interval to the base station and the position of the device.
