• Services & Systems Aspects (SA),
• Core Network & Terminals (CT)

里程碑Milestones

1g Analogue technology模拟技术
2g 第一个数字系统，部署于20世纪90年代，引入语音、短信和数据服务
3g based on evolved Global System for Mobile communication (GSM)(2.5g) core networks and the radio access technologies that they support.

4g LTE and LTE-Advanced have crossed the “generational boundary” offering the next generation(s) of capabilities. With their capacity for high speed data, significant spectral efficiencies and adoption of advanced radio techniques, their emergence has been the basis for all new mobile systems from Release 8 onwards.

5g brings another major technology step, with the creation of a 'New Radio' (NR).
