During the exam, it is not only necessary to have a silent state without mobile phone noise, but it is also essential that people taking the exam are not allowed to use mobile phones and other communication tools. In this case, it is indeed necessary to use a mobile cell phone jammer in the comments, which has actually been invented. The results of the test should be fair to all those who take the test. In fact, in the past period of time, as more and more people use mobile phones to forward responses, it is not easy to guarantee the conditions. Not just for others, now to prevent this situation, shielding cell phone signals seems to be the best choice, now Scrambler high-quality mobile phones that can detect cell phone signals.

A wifi jammer is a device used to block signal transmission from a device operated by signal reception. We seem to get rid of unexpected interference and live a safer life. Here is a brief introduction to our wireless signal interference products. Our mini phone jammer is wireless and portable. It looks like a mobile phone and is very convenient to carry. It can effectively block GSM and 3G signals as well as WiFi and GPS signals. It has been specifically adjusted to interfere with the following cell phone frequency ranges: GSM (850-970 Mhz), GPS (1500-1600 Mhz), WiFi (2400-2480 Mhz). This wireless signal jammer emits low-power radio signals to cut off communication between the base station and all nearby mobile phones. But it can't interfere with mobile phones within a working radius of 10 meters! Its disguised appearance is definitely a spy gadget. In addition, it sells for only $99, so anyone can afford it.

When GPS systems become more and more popular in our daily lives, we talked about gps jammer. The equipment of the GPS system brings us real life, and it helps us a lot. The GPS system is free, open and reliable, and has spawned hundreds of applications that affect all aspects of modern life. You may see GPS technology applications everywhere, from mobile phones and watches to bulldozers, containers and ATMs. In addition, GPS has improved the productivity of most economies, including agriculture, construction, mining, surveying, package delivery, and supply chain logistics management. But GPS equipment can also pose a danger to you, it can easily reveal your location, which can be fatal in some cases. The GPS jammer can solve this problem.

Our company provides various types of drone jammer, which are one of the most effective tools to disable UAVs by blocking control signals. Jammers are used to defeat explosive devices. The jamming drone is used to block the signal of drones and force them to land. They cancelled the transmission of photo or video material from the drone to the operator and caused the drone to lose control while carrying dangerous substances. In other words, the jamming system intentionally transmits radio frequency signals to block drones in a specific area. The jamming system is controlled by special software, which is used to selectively interrupt various command and control communication links used by UAVs, and select the most appropriate means to deal with emerging threats while reducing collateral effects.
