Reading the news these days, I saw such an article:
With the large-scale commercial popularization of 5G around the world, major countries around the world have launched research for 6G. No, the 2023 Global 6G Development Conference will be held in Chongqing.
Technology is really developing too fast, from 2G to 6G, do you remember the changes that each generation of communication technology has brought to your life?Today, we look back at the years of development of communication technology.
There are significant differences and developments in the technical specifications, performance, and application fields of various generations of mobile communication technologies (2G, 3G, 4G, 5G, and 6G). The key features of each generation of technology are detailed below:
Time: Early 1990s.
Key technologies: Digital signals (replacing 1G analogue signals), GSM (Global System for Mobile Communications) is the most well-known 2G standard.
Features:: Provides basic voice calling and SMS services.
Speed: The maximum speed is about 64kbps.
Time: Early 2000s.
Key technologies: Enhanced data transmission capability, UMTS (Universal Mobile Telecommunications System) is a common 3G standard.
Features:: Support for higher-quality voice calls, as well as data services such as web surfing and ** calls.
Speed: The maximum speed can reach a few mbits.
Time: Early 2010s.
Key technologies: LTE (Long Term Evolution) and WiMAX.
Features:: Provides high-definition** streaming, high-speed data transfer, and enhanced network capacity.
Speed: Theoretically, the maximum speed can reach 100Mbit s to 1Gbit S.
Time: Commercial use will begin in 2019.
Key technologies: Utilization of higher frequency bands, massive antenna technology (MIMO), network slicing, and edge computing.
Features:Extremely low latency, huge data capacity, and a wider range of use cases (e.g., IoT, autonomous driving, virtual reality, etc.).
Speed: The peak speed can theoretically reach 10Gbits.
Time: It is expected to be commercialized around 2030.
Key technologies: Still in the R&D stage, which may include higher-frequency band communications (e.g., terahertz bands), advanced AI integration, and quantum communications.
Features:: It is expected to offer higher speeds, lower latency, and new use cases such as augmented reality and holographic communication.
Speed: Peak speeds may be expected to be as high as hundreds of gbits s or more.
The development of each generation of mobile communication technology marks a significant increase in communication speed, reliability and application range. From basic voice and SMS services in 2G to high-speed data transmission enabled by 5G and a wide range of smart applications, every step of evolution has dramatically changed the way we communicate and the way we live. The arrival of 6G is expected to further expand these possibilities, leading us into a faster and smarter future.
