describe the scenaries of applications
when 5G wireless networks become true
- Enhanced mobile broadband scenarios.
4K high definition video, virtual reality, Augmented reality, telemedicine, Remote education, field support, etc.
Enhanced mobile broadband scenario (eMBB) scenario is on the basis of the existing mobile broadband business scenarios, to further improve the user experience, such as performance, is mainly the pursuit of extreme experience of communication between people.
- Big connection scenario
Internet of things, smart city, smart home. Industrial informatization, intelligent logistics and so on.
5G will bring about the ability of all things to interconnect, so that all things that participate in the whole society are capable of perception. The high density of Internet of things can help modern industries upgrade to more advanced smart industries, such as intelligent agriculture, smart industry, smart logistics, etc. For example, intelligent agriculture means that automatic irrigation and fertilization can be achieved by setting up professional sensors to monitor soil moisture and chemical composition. Intelligent logistics can realize the pursuit of valuables by using barter communication.
- Ultra high reliability and ultra low delay communication.
Internet of vehicles, uav network.
The purpose of the Internet of vehicles is to have the communication capacity of V2X, namely, to communicate with people, cars and vehicles, vehicles and road test facilities, cars and networks. After implementation V2X, when people are driving on the road, vehicle by signal can be told in advance the owner road conditions and environmental information, such as soon after a crossroads, don't need to rely on the driver's observation, vehicles can be automatically whether there will be other vehicles through the induction to the intersection; For example, when a signal in the distance changes, it can communicate with the vehicle through the traffic signal, without the need of visual.
The establishment of uav networks also requires the support of ultra-high reliability and low delay communication. Traditional uav remote control system USES is "point to point" on the remote control signal transmission mode, the remote control of unmanned aerial vehicle (uav) is used for image transmission signal frequencies, can support high bandwidth of video transmission, but relatively short transmission distance, up to 5 km, and easily influenced by the surrounding environment, remote control signal penetration will decline, so normally only fly in the line of sight range. And 5G uavs can break the bottleneck of "point-to-point" remote control signal transmission. In theory, the uav can be remotely controlled as long as there is a telecommunication signal coverage.
