4G communication network changes life
Next generation communication network technology
How will it change the future of mankind?
Intelligent cooperative wireless communication platform team, Department of electronic engineering, Tsinghua University
Creating the future communication network world!
Why do we need next generation communication networks?
Original 2G, 3G, 4G
From voice to video to multimedia and Internet
People's feelings can be basically satisfied
But that's not enough
Object oriented communication
Not only between people, between people and machines,
It will also be transferred from people to machines
Machines can also communicate with each other through communication
Cooperate to complete the task
In the next generation communication network, the first thing to realize is "accessibility"
We often use communication through electromagnetic waves
In other environments, it may not be feasible
For example, underwater, it depends more on sound
Or propagate signals with the help of light
Therefore, the next generation communication system should be able to select automatically
Optimal transmission mode to achieve seamless switching of communication media
In addition, we should build a new network organization structure
When we start from a communication monomer
By connecting them into a network
It's like a room where only two people talk
Into a lot of people talking
How to ensure that they can hear each other clearly
Without interference with each other?
This requires the establishment of heterogeneous networks between monomers
Intelligent cooperative wireless communication platform team
Hope to design more flexible "heterogeneous network"
It can adapt to different environments and different shapes
Fill the whole environment like water
Put into the application scenario
Take the communication of Internet of vehicles as an example
Automatic driving is now mainly the intelligence of a bicycle
The team hopes to realize heterogeneous and flexible networking of the Internet of vehicles
It can connect the vehicle with the base station, the vehicle with the roadside unit and the vehicle
Seamless transmission switching, reliable and timely communication
Through this way of "vehicle road coordination"
It can make each car see more and farther
Improve the safety and accuracy of automatic driving
Improve traffic efficiency
We can't see or touch "communication" technology
Still changing the future of mankind
Transmission through communication network
People have expanded tactile perception to the greatest extent
Maybe another 10 to 20 years
We can experience "immersive communication"
By then, the "separation" in science fiction
It is possible to achieve this!
If 4G network changes people's life
So the next generation of wireless networks
It will infinitely expand the limits of human eyes, brain and limbs
Change society, change the world
Are you ready?
Let's prepare for the new era of all things Zhilian!
