All operators around the world are eager to shut down their GSM network. European GSM operators are more cautious. French operator Orange said it will not shut down the GSM network on a large scale. Telenor, the Norwegian telecommunications operator, recently announced that it will shut down its 3G network by 2020, but it will shut down its GSM network by 2025, when its third-generation w-cdma network will cease to exist. European operators should not try to shut down the GSM network so hard, nor to consider the large number of communication needs between devices. If they are eager to shut down GSM, the current European operators can still profit from mobile international roaming communications. , Will face the economic and regulatory issues of the EU. In the Chinese market, a large number of elderly people still use GSM-based non-smart phones. And the basic voice and text messaging services are still using the GSM network. Communication equipment based on the GSM network is still very important today, such as wireless alarm systems, robots and other tools and equipment. If you need to block these tools or mobile voice communication and messaging services, you may need a gps jammer, portable or desktop. Portable jammers are easy to use anywhere, and desktops are more powerful.
GSM network functions affect people's lives. This is not only the basis of mobile phone voice communication and short message service network, but online news recently said that the latest technology of cruise navigation and drone tracking in Russia using GSM network also has very important applications. Russia's latest "defense" airspace monitoring system can use wifi jammer networks to identify and track drones, cruise missiles and low-altitude aircraft, but can track airspace below 500 meters (less than 500Mm / s), and the latest monitoring system can be used to upgrade Civil aircraft to assist the rescue operation after the crash. GSM is an abbreviation of Global Mobile Communication System, and is the most widely used digital radiotelephone technology in the world. The protocol describing 2G cellular networks is a standard. This protocol uses base stations to generate radio frequency signals for stable electromagnetic fields to relay information. When the magnetic field in the metal occurs, an interference signal will be generated. Rubez can be detected and recorded. Using Doppler effect and triangulation, the precise coordinates of the target can be determined by analyzing the signal changes recorded by the base station. Once Rober Day captures the target, the data is sent to the surveillance center via the GSM network, including the Defense Management Center of the Russian Ministry of Defense and the Command and Control Center of the Russian Space Iraqi Air Defense System.
The ignition lock and manual lock installed on the car cannot effectively prevent the car from being stolen, so many modern cars are equipped with electronic anti-theft alarms. When a theft occurs, the alarm horn will make a sound for a period of time, thus shutting down the car's engine. A communication platform with remote monitoring function is designed, which provides a comprehensive solution for vehicle anti-theft and monitoring, and provides a technical foundation for the wireless network development of vehicle anti-theft systems. It is widely used in many vehicles, but vehicle theft cases have not been completely eliminated. There are also many professional thefts that use high-tech methods, equipment interference and attacks on car security systems. GSM signal jammer can interfere with the GSM network in the anti-theft system.
With the development of the Internet, wireless network technology has developed rapidly, making it the main communication network in people's lives. The development of wireless networks and smart phones has increased the number of online criminal cases, and the punishment for cyber criminals is mainly limited to most countries in the world. In the past 20 years, the rise of new technologies has led to the rise of cybercrime. If a series of movies or movies such as Mr. Roberts or hackers are used to amplify the pirates, most of their online activities are still illegal. To curb the threat, Gavin, chairman of the Thomas and Guild of Police Commissioners in England and Wales, provided a simple solution: Do we attach 4G jammer to cybercriminals? Cyber criminals connected to WiFi jammers cannot access the Internet within a fixed time.
GPS positioning may put us in danger, which is not conducive to our travel, and it can be targeted no matter where we go. Therefore, the micro drone jammer device is a tool you urgently need to ensure your travel safety, and it is a very effective tool. The safety of travel here is not general safety, but a hidden safety hazard brought by GPS tracking. In addition to the innovation of new mobile phone baseband chip technology and the strong support of carrier network systems, today's smartphones can also achieve smooth Internet access, watch videos, remote voice and other functions. 2G network calls, 3G network access to the Internet, and 4G networks can see video. With the continuous improvement of network formats, mobile phone functions have also undergone tremendous changes. Now, with 4G networks all over the country, operators and telecom operators have begun to actively allocate 5G, hoping to further expand the network format
Here, I will introduce to you the miniature design of the car portable jammer device, which uses an antenna, GPS L1 interference signal, GPS L1 signal is a common basic GPS signal spectrum design, and the jammer can make you escape well The GPS signal tracks you, and its mini shape design makes it unnecessary to put in the battery, no need to charge, and directly plug it into the car cigarette lighter socket to start working. During use, your car will not be positioned by GPS, mini design It also makes it easier to hide. As we all know, many countries prohibit the use of signal jammers, especially for private use. They will disrupt normal communication systems, cause inconvenience to others, and even cause greater losses.
When we enter the word "GPS jammer" in Google Chrome, we will see a lot of information about the word, some of which are GPS signal jammer sales stores, and some of them are blogs about their related news. In these stores, the products they sell are different, and even in the same design, the prices are very different. Answer: Are expensive products better than cheap ones? In fact, many people have the mentality that high-quality products must be better than lower-priced products. In fact, this is not exactly the same, and because the manufacturing and transportation of the product may be quite different, the price will be higher, but the quality is the same.
