The fifth generation of mobile communication technology, or \"5G\". Its \"5G\" is an abbreviation of the English \"5th generation\
The proposal and development of 5G systems is a strong demand for global mobile communications in 2020 and beyond. On June 24, 2015, the International Telecommunication Union (ITU) announced that the official name of 5G technology is \"IMT-2020\". \"IMT-2020\" is the fifth generation mobile phone mobile communication standard, transmission speed is 40 times faster than 4G network, and has low latency and other features. And announced that the relevant standards will be completed in 2020.
The concept of \"5G\" :
\"5G\" represents an evolution and revolution in mobile technology, reaching several high-level goals announced to date by various members of the wireless ecosystem. It is widely believed that 5G is the next generation of wireless technology that will allow cellular networks to expand into new use cases and vertical markets. 5G technology will also allow cellular networks to enter the machine world, which will benefit the likes of driverless cars and be used to connect millions of industrial sensors, as well as various wearable consumer electronics devices.
\"5G\" is different from 4G, 3G, and 2G systems. 5G is a general term for solutions that integrate the technological evolution of existing wireless access technologies (including 2G, 3G, 4G and WiFi) with new complementary wireless access technologies. Or 5G will be a truly converged network. This unified standard will provide high-speed, secure, and free connections between people, people and things, and between things.
The 5G network architecture will be further flattened, it will be a powerful base station superimposed on a large server cluster. And more novel architecture such as \"C-RAN\".
●5G base stations will be more miniaturized and can be installed in various scenarios; With more powerful functions, traditional aggregation nodes will be removed;
●5G network speed greatly improved. 100 times faster than 4G\/LTE's peak transmission rate of 100M per second;
The 5G network should meet the requirements of super-large bandwidth, ultra-high capacity, ultra-dense sites, ultra-reliability, and anytime and anywhere access. Therefore, the industry believes that 5G should be a wide-band, ubiquitous (that is, a widely existing network), intelligent, integrated, green and energy-saving large communication network
