jammer

When using active interference, you do n’t have to worry about putting yourself or anyone else at risk. Police, fire and EMS radio users and pager users can still communicate, but your customers, customers or students will not be disturbed by non-emergency mobile phone conversations, thus providing a quiet environment. Once the jammer is turned off, the phone will automatically re-establish communication with the cellular base station-those base stations affected by the jammer will again be able to receive cellular-based services. It should be noted that using a jammer will not damage the phone in any way. It should also be noted that the same situation applies to any GPS jammer model we carry.

Some customers ask why we do n’t carry remote control jammers, code capturers, and LoJack blockers, or whether we can build or obtain them customarily. The answer is no. In the "Signal Jammer", we are equipped with professional signal blockers, detectors and other practical and productive equipment, rather than tools that encourage criminal mischief or annoyance.

The GPS signal is a radio signal using a specific frequency. GPS actually has two main frequencies, one is mainly used for public non-military purposes (1575.42 MHz), and the other is only used by the US military (1227.6 MHz). Since GPS is nothing more than weak radio waves, although technical equipment and expertise are required for this purpose, the use of GPS jammers can interfere or distort these waves.

Mobile phone jammers are becoming more and more popular in schools, for good reason. Many teachers are tired of trying to stop students from texting in class and wonder how to stop cell phone use in class. Students will ignore lectures when browsing social networks. Some people text or even conduct research online to deceive the exam. Although these jammers can terminate mobile phone communication and seem technically complex, you may be surprised by their simplicity, which can be achieved by pressing a button.
