Over de reis:

First of all, GSM is the basic network band for mobile phone voice communication and SMS services. As we all know, improper use of mobile phones is very serious, the use of mobile phones in public places will have a great noise impact on others. Can you imagine how annoying you feel when you are reading and relaxing quietly when someone suddenly calls? I agree. When we need to be quiet, we don't like to be disturbed. The gsm network frequency band is very important for the use of electronic equipment. Therefore, in many places where the use of mobile phones is prohibited, interference devices that block basic mobile phone communication are installed. This is what we usually call gsm jammer. https://www.perfectjammer.com/gps-blockers-jammers.html We need to understand our needs to buy a gsm scrambler. For example, in addition to the gsm network, we need to shield the signal type. Is it necessary to shield the 3G and 4G network frequency bands. In this way, we can buy a cell phone blocker that blocks all cell phone signals. In addition, we have purchased electronic interference equipment, we need to consider where to use. Portable jammers help us use indoors and outdoors, while desktop jammers use multiple antenna designs. As the name suggests, because of their wider interference radius and more types of signal shielding, they will be used not only for individuals, but also for prisons, court schools, and other larger venues. https://www.perfectjammer.com/wireless-wifi-bluetooth-jammers.html Today, 4G or 3G phones and networks are common, and there are many machines and devices that use GSM networks to connect to the Internet, and these devices have a long service life. GSM networks are inexpensive and cover a wide range, so many "device-to-device" network applications use GSM networks, including alarm systems, vending machines, and transportation vehicle management. Based on the experience of AT&T and other companies, upgrading a mobile network from 2G to 3G or 4G is an absolute economic option. If the M2M application for communication between devices is upgraded to a new network, it can also be significantly improved. For example, in the Internet application of a shipping company, if you switch to 3G or 4G, the related chips and applications will be able to support real-time video transmission and other functions. https://www.perfectjammer.com/ Russia’s latest technology will be used in a wide range of fields (mainly in the field of military defense), which will greatly improve its air defense capabilities. In addition, it will be used for other monitoring applications, such as drone rescue, which will become an important research site. So far, the development and widespread application of unmanned aerial vehicles have made it very important. Drone rescue and drone delivery have been used in many countries around the world, and this tracking technology can better provide better accuracy for these operations. The use of GSM network and tracking technology is also likely to become the tracking of many major criminal gangs, so to avoid such tracking is likely to require the use of basic GSM jammers, portable design will be more convenient, follow-up actions for you. https://www.perfectjammer.com/all-gsm-3g-jammers-blockers.html With the arrival of 5G, the 2G network (GSM) will gradually disappear. People in the communications industry expressed different views on this issue. The most important thing is to understand the impact of 2G network withdrawal on future user communications. The biggest role of 2G network is to undertake a large number of voice services and SMS services for mobile users. Therefore, in the early days, we were able to use feature phones to successfully make calls and send text messages, and feature phones were supported by 2G networks. According to reports, the 2G network was able to implement some Internet functions at that time. Apart from making calls and sending messages, there seemed to be no place to connect to the network. The arrival of the 3G network era makes it very easy for people to access the Internet. Users still need to rely on 2G networks to make calls and send text messages. 3G can only guarantee normal Internet access. 2G is still the backbone of voice services and SMS services. The emergence of 4G allows people to watch videos smoothly, but users still use the 2G network when making calls and sending messages, even if the new 3 g, 4 g, and 5 g networks are used for People use the Internet to provide a lot of convenience, and the 2G network will not stop using it because the basic call and SMS services rely on the GSM network. https://www.perfectjammer.com/drone-signal-jammers.html With the increase in car theft worldwide, major car manufacturers and drivers are looking for the most advanced car anti-theft system, and the GSM network application anti-theft system has also made great progress in recent years, gradually improved, and become an umbrella for car anti-theft devices . In view of the increasing trend of auto theft in today's world, auto manufacturers are constantly improving security technology, especially with the development of microelectronic technology, auto anti-theft technology automation, and intelligent direction. According to its structure and function, car alarms are divided into four types: mechanical, electronic, chip and network. Among them, the mechanical lock is the most traditional anti-theft device, usually not used alone. Electronic anti-theft system is currently the most widely used equipment. And chip digital security equipment and network security systems are the development direction of automotive security systems. This article is based on the basic principles of the car anti-theft system involved, using the GSM short message protocol data information processing system. https://www.perfectjammer.com/all-cell-phone-jammers-blockers.html
