GSM is the most widely used digital radiotelephone technology in the world

With the continuous popularity of mobile phones, basically everyone will have a better smartphone in their hands, but many people still don’t know what GSM does. First of all, GSM is the basic network frequency 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 read and relax quietly when someone suddenly calls? I agree. When we need to be quiet, we don’t like to be disturbed.

GSM also supports indoor coverage. The power of the outdoor antenna can be distributed to the indoor antenna distribution system through the power divider. This is a typical configuration scheme used to meet the high-density call requirements common in shopping centers and airports in homes. Indoor coverage can also be achieved through wireless signals in buildings, but this can improve signal quality to reduce interference and echo.

When telstra announced the closing time, its executives stated that GSM accounted for less than one percent of total traffic. For operators, shutting down the GSM gps jammer network has both technical and economic advantages. The frequency resources released after the network is shut down can be used to build a new generation network, which means that the same radio frequency resources can transmit more data traffic. In addition, after the GSM network is closed, the operator’s operation and maintenance costs will also be greatly reduced.

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 have a wide coverage, 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.

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.
