What is GSM technology? Explore the technical mysteries of global mobile communication standards.

GSM, Global System for Mobile Communications, is a global mobile communications standard. It uses TDMA (Time Division Multiple Access) technology, which allows several users to share the same frequency band of radio spectrum and divide it into many independent time slots in time for different users. The advantage of this technology is that it improves spectrum utilization, allowing more users to communicate using the same frequency band at the same time.

What is GSM technology

The core of GSM technology is digital voice coding, which converts analog voice signals into digital signals for transmission. This kind of digital signal has the advantages of strong anti-interference ability and stable transmission quality, making the call quality clearer and almost unaffected by external interference.

In addition to basic voice communication, GSM technology also supports SMS services. Its SMS transmission speed is 160 characters per second. This service plays an important role in today’s digital communication era.

In addition, GSM technology also has an encryption function. By encrypting communication content, it ensures the privacy and security of users’ calls and text messages, effectively prevents the risk of information being eavesdropped and tampered with, and provides users with more reliable communication guarantees.

What is GSM technology

In the GSM network, the base station subsystem (BSS) and the network subsystem (NSS) together constitute the entire network structure. BSS is responsible for the allocation and management of wireless resources, while NSS is responsible for core functions such as user authentication, positioning and connection management. The two work together to achieve the effective operation of mobile networks.

In general, GSM technology, as a pioneer in global mobile communications, provides convenient and efficient means of communication for people’s daily lives and business activities, and has about 90% of the world’s users. Innovations in its core technologies such as TDMA, digital voice coding, SMS services and encryption functions continue to promote the development and progress of the mobile communications industry. It is believed that in the near future, communication services based on GSM technology will become more popular and perfect, bringing more convenience and speed to people’s lives.
