5G means the fifth generation mobile communication technology. As we know, we are in the 4G time, 4G network allows us have a high speed of 100Mbps which is 12.5MBps, to download something. So we can download applications in a short time now. But what things will be in the 5G time?

5G network allows us have a speed of 10Gbps to download applications. That means we can download a blue-ray movie in a few seconds. But if 5G network comes, we may not enjoy the high speed of 5G. Because the write speed of common solid disk is about hundreds of MB/s while our download speed is about 1.25GB/s. So when we have finished downloading, our computers have not finished writing data to the hard disk yet. So if 5G network comes, our hard disk technology must be updated!

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.
