At the same time, in densely populated areas or the current network is not enough Dense areas are covered deeply and can go underground, such as subways, tunnels, parking lots, mines, and other special places with poor signals. Through high-orbit satellites and low-orbit satellites, the surface is guaranteed to exist in any corner of the earth. The integration of the network can take into account the surface and the point. On the ground, through many repeaters, small The base station provides deep coverage. A network can not only provide land coverage through ground base stations but also jointly network through low-orbit satellites and high-orbit satellites. 6G may have a trend of integration between heaven and earth. 6G will further integrate the networkĪt present, the mobile communication network and the satellite network are two independent networks, which operate independently and cannot play a role of integration and supplementation. Therefore, in this sense, 6G will not undergo technological revolution again and make revolutionary changes in the system, but based on 5G, according to the actual operating situation, new problems are found, or the deficiencies of 5G are improved. So, can 5G realize all visions and achieve perfect feelings and experiences? Not 5G also undergoes a long-term evolution process, and gradually improves from the network, management system, and other aspects.
The 5G revolution embodies huge changes in technology, management, billing, business models, business models, and business forms. This network integrates mobile Internet, smart sensing, big data, and smart learning to form new capabilities, which can be said to be a revolutionary change. The business formed based on 5G is no longer limited to the transmission of information, but a smart Internet. Compared with the 4G network, 5G adjusts and rebuilds the entire network structure, and the core network, management, and billing system will also undergo tremendous changes. However, with the advent of 4G, the efficiency of these services has been greatly improved, ushering in the outbreak period.ĥG has made more demands in technology, with faster speed, lower power consumption, and lower latency. Even a large number of 4G services are gradually built based on 3G. We can understand 4G as technological evolution, but the network speed has increased, and its infrastructure and basic capabilities have not changed revolutionarily compared to 3G. However, objectively speaking, the network speed of 3G is still relatively slow, and 4G has greatly improved the network speed, which has greatly improved the user experience. From 2G to 3G, it is a revolution for the communication network and a completely new transformation. The core network and billing system are data-centric systems. Data services have become an important business. After entering 3G, although the voice is still very important, the network is no longer voice-centric. The core network and billing system of telecommunications companies are based on voice. The amount of data used by users is also very small. Internet access is a very secondary capability. Although 2G also has digital communication capabilities, it mainly sends SMS and caller ID. 3G is moving from the era of digital communications to the era of data communications.
This is the same as the evolution from 3G to 4G.
