The development of mobile communication

1, the first generation of mobile communication technology used analog signal transmission, the main feature is the use of analog technology and frequency division multiple access technology, with many formats. TACS system is mainly used in China, and the transmission rate is 2.4kbps. Due to the limitation of transmission bandwidth, it is impossible to roam long distances in mobile communication.

2. The second generation mobile communication technology is mainly digital transmission, and its main feature is that it adopts time division multiple access technology and spread spectrum communication technology to realize the reuse of wireless frequencies and improve communication capacity and anti-interference ability. At the same time, 2G technology also supports voice and low-speed data communication.

3. The third generation mobile communication technology is mainly characterized by multimedia communication. It can realize high-speed data transmission and broadband multimedia services, such as video calling and mobile Internet, by adopting CDMA technology and broadband wireless communication technology.

4. The fourth generation mobile communication technology is a widely used mobile communication technology, which is based on orthogonal frequency division multiplexing technology and has the characteristics of high speed transmission, low delay and high reliability. 4G technology also supports multiple access modes, such as TD-LTE and FDD-LTE. , and has become a widely used communication technology standard in the world.
