When introducing each jammer, we emphasize that the jammer's interference range is for reference only, please refer to the actual situation. The interference range depends on the local signal strength. Here, we will try to explain why the scope of work of manufacturers is often different from the actual situation. First, when the jammer is manufactured, it will be tested. There are many necessary tests, such as battery life, transmission frequency, etc., including testing the interference radius. Manufacturers always believe that the test results are more effective than the actual range, because these devices are often tested in open spaces. You know that buildings and different concrete structures can hinder signal transmission. Most of us live in big cities and we are surrounded by high-rise buildings. The signal strength of the local mobile phone is also an influencing factor. Therefore, if the interfering device cannot block the phone within 30 meters of you, you need not be surprised.
We use different smart devices every day, such as GPS navigator, laptop, smart phone, etc. These devices provide us with a lot of convenience, but there is no doubt that your personal information will also be leaked from these devices. You can say that your wireless device is a double agent for the stolen. We use Wi-Fi connection, but we don't know it is easily hacked. We use Bluetooth and we have never heard of Bluetooth hacking technology. When we use GPS to determine where we are and how to reach the desired location, we find that there may be GPS tracking.
The security problem of wifi network has always existed all over the world. The encryption method of wifi is also gradually improved, and hackers will crack new technologies. Wifi encryption and three security modes. You can use mobile phones, tablets and other devices to make the device more convenient. The user can use his mobile phone or tablet to simply set up an Internet-connected device without a screen, such as a smart speaker. Personalized data encryption. WPA3 is a function to encrypt the connection between each device and the router or access point. WPA3 can assign different encryption keys to different devices, so it can be effectively reduced by bag grabbing, offline analysis and password extraction Attacker's risk.
In terms of software, if someone takes your phone away, special hardware modification is required, so even if there is no software to disguise the shutdown, the battery is dead, and the battery power is low, your phone will be tracked. Usually, such software calls GPS and network when running, and the power consumption after shutting down will be higher. Therefore, if you find your phone within a certain period of time after shutting down, you may find obvious power loss when you turn on the phone, or use the phone daily but the traffic A lot of consumption is obviously conquered, trying to find the best. It has become a habit that people go out to carry mobile phones. How to prevent the mobile phone from being tracked and located? Who is being monitored, especially on their mobile phones. If we become the target of criminals, it will pose a threat to our lives. Here are some tips on how to track your phone.
In recent years, with the development of unmanned aerial vehicles (UAVs), the application fields of unmanned aerial vehicles (UAVs) have become more and more extensive. UAVs can be used to send rapid airdrops and erect cables in the air. Rivers, police drones can handle road traffic accidents, large-scale geophysical survey projects in the air, and will also be able to perform maritime rescue, combat, and emergency operations. The development of drones comes from military demand. Drones were developed in the early 20th century. In 1917, the first drone was developed. In the 1950s, some countries began to develop drones for war. At the end of the 20th century, the combined detection of composite drones has been widely used worldwide. UAVs are also more and more widely used on the battlefield. In the military field, UAVs have many uses, such as drones, reconnaissance aircraft, decoys, electronic countermeasures, including aircraft, attacks, In addition, it can also be used for target recognition, communication relay, anti-submarine, aerial firepower correction and distance measurement to the atmosphere.
The US military has been equipped with an anti-drone system called AUDS, which allows us to easily kill enemy drones within 10 kilometers. As far as the development of air defense weapons is concerned, China's level of development is no less than that of the United States, and China has developed various anti-drone equipment with various killing and killing mechanisms. For example, China's Skynet 1 anti-drone system can be used to capture and capture enemy drones. An anti-drone system called AUDS has been used by several US troops. The AUDS anti-drone system was jointly developed by the British Bright Surveillance System Company, chesky power and the enterprise control system. It is a very cost-effective UAV defense system.
