Barcelona News on February 24 (Wen/Sun Fenglei): Many people may not use 4G mobile phones, but 5G has become a hot word at this year's MWC Mobile World Congress, and also links 5G with IoT applications. Together, 5G, which is still not even standard, seems to borrow the Internet of Things, and even the Internet + Dongfeng to catalyze 5G. Why does the Internet of Things become the driving force of 5G? The Internet of Things, which used to hang on the lips, seems to be enough for 2G and 3G. But now I have to look forward to 5G?
The characteristics of 5G are decided, and more can be done for the Internet of Things.
Since the 5G standard has not yet been introduced, we will see how Qualcomm, which has a large number of patents in the field of wireless communication technology, views 5G.
Qualcomm executive vice president and QCT president Cristiano Amon explains the difference between 5G and 4G: The power of 5G lies in its ability to provide mission-critical services for wireless networks. Wireless connectivity is everywhere, but many mission-critical services still rely on wired connections. One application scenario for 5G is to achieve the high reliability required in wireless networks and create new services in industry and security.
Because the 5G rate is faster, the delay is shorter, and the access network is more, the density is higher, and the reliability is higher, so that the mission-critical service can be guaranteed.
Mission-critical services bring 5G and the Internet of Things together
At the MWC World Mobile Conference where communication giants gather, from the communication technology solution providers such as Ericsson, Huawei, Qualcomm and Nokia, to the global big-name operators such as China Mobile, Deutsche Telekom, France Telecom, etc., without exception The solutions and cases of 5G and IoT applications are on display at their own booths.
The case they show seems to be more like a scene in a science fiction film, but it is also the most concrete presentation given by the Internet of Things and 5G.
Unmanned driving
On the Nokia booth, a model like this was placed:
If you reach out to block any of the cars, the car will automatically brake, the other cars are still orderly, the deceleration of the deceleration, the braking of the brakes, the unaffected car continues to move forward.
Such an orderly traffic requires a low network, a low latency, a millisecond response speed, and a fast vehicle response. At the same time, the 5G network has a large capacity, and even if the traffic volume is large, it can still carry a large car. Traffic can only eliminate traffic accidents.
2. Intelligent transportation
If you talk about intelligent transportation in general, it is better to give a realistic example.
Ericsson and Sweden's truck and bus manufacturer SCANIA have developed a solution for vehicle formation. For the transportation industry, fuel consumption is the most important part of their cost. Reducing wind resistance is an effective way to reduce fuel consumption. SCANIA proposes that the closer the driving distance between the two cars is in the truck, the more the wind resistance can be reduced and the fuel consumption can be reduced.
Therefore, Ericsson and SCANIA have developed a solution to help trucks interact with each other, perceive the perceived distance and control the distance between transport vehicles. Under the existing 4G network, the distance between the two vehicles can be controlled between 25 meters. If there is a 5G network environment, the distance of the vehicle can be controlled within 3 meters, and the wind resistance can be reduced to a greater extent.
3. Industrial application imagination
Industry 4.0 is booming in the country. If you have 5G, you can make Industry 4.0 richer and fuller. Many displays can prove this.
In his speech, Ericsson President and CEO Wei Hansi showed ABB's cooperation with Ericsson. On the Ericsson booth, an ABB robot was placed. The CNET reporter experienced it on the spot and held a similar "pen". The robot operates, and the other end of the machine will respond according to the operation of this hand.
If the drill at the other end touches the steel plate and starts the electric drill, the manpower on this side can feel the steel plate being drilled. The strength and feel are like the resistance and reaction of the steel plate felt by the electric drill.
According to Sara Mazur, Dean of Ericsson Research Institute, such robotic operations require very high reliability and are impossible to achieve in an existing network environment.
In fact, in the Industrial Internet, more emphasis is placed on the collaborative work in the factory and the cooperation of the various processes. Therefore, in the 5G environment, it is possible to make the factory, even from the inventory, production to sales, more precise.
4. Remote surgery
If ABB's robots can't more convincingly explain how much reliability the Internet of Things needs, then does remote surgery sound serious.
At the China Mobile booth, Nokia and China Mobile jointly demonstrated the cooperation of two robots, and the two robots cooperated with each other.
If the two robots are in the telemedicine scene, they can be two real-time surgical robots. The doctor operates the robot at one end, and the robot arm at the other end is synchronized with the doctor's operation, and the doctor is now Not in the room with the patient.
5. Virtual reality
Virtual reality can be said to be a hot demonstration on MWC this year. Even when Facebook founder and CEO Zuckerberg appeared in the MWC keynote speech, the application of virtual reality technology can help Facebook users make their sharing more vividly. .
Of course, the virtual reality on MWC is different from the common VR glasses, not to play games more fun, but like the Ericsson booth, the communications engineer in downtown Stockholm with VR glasses, remote control remote In the suburban drone, go check the base station for any faults.
It may also be a 360-degree camera with no dead ends like the Nokia booth for data acquisition and transmission.
