Cell phone signal will be lost within the range of the jammer
Mobile phones use unique frequencies for calls and listening. Most cell phone jammers will block either of these two frequencies, thereby indirectly providing a preventive effect on these two frequencies. Cell phone cell phone jammer work on the same principle as jammers that prevent radio communications. They work by interfering with the frequency from the mobile phone to the base station or from the base station to the mobile phone. Effectively block signal transmission from UMTS, 3G, CDMA, GSM and PHS networks. Jammer devices may not be able to operate on different frequencies because the phones operate on different frequency bands in different countries.
The jammer can effectively defend against drones several miles away. Generally, GPS jammers work with the distance ratio between the drone and the jammer relative to the pilot. The farther the drone is from the pilot, the closer the interference, the better. A typical effective interference direction is a cone of about 15 to 30 degrees, protruding forward from the spray gun (this is also affected by the RF frequency band and jammer power). The new cell phone signal jammer can protect you from interference and meet your needs. Please note that this product is designed to protect user privacy, please do not use it in criminal activities. Therefore, please ensure that your activities are permitted by law, otherwise we will not be responsible for all your illegal actions. Due to the fraud of communication equipment in previous college entrance examinations in recent years, in order to completely eliminate this phenomenon, signal jammers have been widely used.
Most mobile phones use 3G 4G signals, which specialize in handling 2G signal interference. We know that a smartphone jammer is a mobile phone signal transmitted from a device to a mobile phone in the same frequency range. Another reason for strong interference is that the mobile phone jammer is lost in the signal range. I don’t know the reason, but only the difference in reception. . You can access more portable, fixed, adjustable, GPS, WiFi, Bluetooth and other mobile phone types of jammers here. Please note that this product must not be used for criminal activities. Therefore, please ensure that your activities are permitted by law, otherwise we will not be responsible for your illegal actions.
