We often say that 4G has changed life, 5G has changed the world, but 6g technology is more powerful.
Moreover, the arrival of the tactile Internet here will mean that the transmission of information in the future will go beyond video, sound, words and pictures, including the transmission of touch, taste and even emotion, which can greatly improve the efficiency of network communication and learning, and can directly stimulate people's cerebral cortex through brain-computer interface, thus forming physical memory and bringing us a new way of learning. There are many application scenarios of 6g, including cooperative body area network between machines, super traffic virtual assistant, emotional and tactile communication, multi-sensory mixed reality, intelligent interaction, space, communication, tactile Internet, holography and so on.
When we were in the 1G era, we could only simulate sound waves. At that time, we could only make phone calls and could do nothing else. Moreover, when analog sound waves transmit signals, the distance is too far and it is easy to be distorted. In the 2g era, we can send short messages. After 3G, we can surf the Internet again. After the development of 4G network technology, we can watch videos again, and the network speed is getting faster and faster. Body area network means that humans can use more body organs that can be replaced or implanted. We can even install nano-robots in the body to dynamically monitor the operation of various organs in our body in real time. Real-time simulation and tracking of the running state of human body in the network can intervene and predict the location of lesions in advance, which also improves our quality of life.
And on the basis of the 6g network, the control of the drone and the driverless experience of the car will become better, and users will hardly feel any time delay, just like you are personally controlling. The network speed of 6g will be 100 times faster than that of 5G, which can almost reach the speed of 1tb per second. That is to say, if you want to download a movie, it can be completed in one or two seconds, while the network speed of 5G can reach several hundred MB per second. If you want to download a movie, it may take a minute or two. This gap is very obvious.
The sixth session can also help us locate accurately. A key index of 6g technology is that the indoor positioning accuracy can reach 10 cm, while the outdoor positioning distance is only one meter, which is 0/0 times that of 5c. The communication delay of 6g is only 0. 1 ms, which is also 5G 1/65433.
