From 2G to 4G a group of Internet products have been fired Which products do you think will be fired?

From 2G to 4G, a group of Internet brands have been brought to the fore, and in the 5G era, products that have been speculative for many years are likely to get angry.

The constant evolution of mobile communication technology has constantly changed our lives. In the 2G era, limited by the speed of the network and the performance of mobile phones, people only pay attention to their mobile phones at that time, whether there is any signal, whether they can make calls, in the 3G era, the network speed has been greatly improved, especially the emergence of the first batch of smart phones. In the 4G era, the speed of the Internet and the mobile phone have taken a big step forward, mobile payment, and various Internet news media, Internet shopping stores, various live broadcasts. Video, and even form products such as Internet phones and Internet cars.

4G can change our lives and has been integrated into our lives, just like the basic elements of life such as coal, gas, water and electricity. However, the 4G network has limited capacity and speed, and has high latency and other shortcomings. It is difficult to meet the needs of mobile networks now and in the future. There is an urgent need for a network with higher bandwidth, faster network speed and lower latency than the current 4G network. appear.


The 3GPP organization and the ITU organization have played a big game. In their hearts, the future 5G is a network that can connect all things. They also divided the future 5G application scenarios into three directions, namely enhanced mobile broadband, large-scale machine communication and high-reliability low-latency communication.

Because some players in the communication industry chain open small stoves, they want to set up their own 5G standards, which in turn affects the 3G standards of the 3GPP organization and the final global use. The 3GPP organization was forced by the market pressure to fight the night battle. It just pulled out the first version of the 5G protocol Rel-15 and frozen the standard in June 2018, which means that it is no longer possible to add new features to the 5G standard. However, this is a haste. The published protocol only covers the standard of the enhanced mobile broadband application scenario, and the standards including the Internet of Things, Internet of Vehicles, industrial automation, and smart city applications have not been released (Rel-16 included), from this point It can also be seen that the 3GPP organization is also facing a strong "reverse" pressure.

5G is designed for so many scenes, which means that our life will undergo tremendous changes in the 5G era.

On the one hand, 5G will change our lives. For example, after 5G matures, we can use virtual reality technology to make movies; sitting at home to watch the World Cup is like being on the scene, because the image can be directly projected onto our retina, bringing an immersive experience.

On the other hand, 5G technology will also play an important role in education, medical care, transportation, etc., and will help us make full use of the overall resources and create greater value.

I would like to ask which products in the 5G generation are definitely hot. I think that the products that have been speculative for many years are really likely to be fired now. I have to say that they are autopilot and VR/AR.

The first is VR/AR and other products, which is a product that does not rain when it is light, and it has been fried for many years, but it still does not fire. VR has done a bad job in the domestic market. Although it has not been accepted by consumers, the VR industry chain, including hardware, software and components, has gradually matured and shaped. For AR, although it is not fully mature, AR products with different forms have begun to be widely adopted by developers.

5G's high reliability and low latency communication is very suitable for this product form. If the weight problem, power consumption and heat generation of VR/AR glasses can be solved in the future, with the application and popularization of 5G technology, it will be given to users. Bringing an immersive experience and driving the entire VR/AR industry forward.

The second is the self-driving car, which is also a typical case of thunder and no rain. At this stage, China's major OEMs have basically had the L2 level of automatic driving capability. In 2018, some of the mainframe factories have achieved mass production. It is expected that mass production will be carried out in larger scale from 2019 to 2020.

In addition, some domestic enterprises are already conducting L3/L4 self-driving trucks and delivery vehicles for testing and trial operation. Many companies plan to achieve mass production and commercialization of L3/L4 automatic driving in specific scenarios from 2019 to 2020. .

However, any existing network cannot popularize autonomous driving on a large scale, because the overall process of automatic driving includes three steps of sensing, decision making and control execution. It is obvious that the current bottleneck is in terms of network latency and reliability. In autonomous vehicles, time may mean life, LTE delay is 98ms, and 5G delay is 1ms, which is basically one percent of LTE. This short one second means safer. Save more lives in an emergency.

In short, the future 5G network is a network of all things in tandem, and also more intelligent, will bring us a different life experience.
