5G standards will be completed in 2020. Here are the things you should know about 5G

Recently, the International Telecommunication Union (ITU) held a working meeting in San Diego, California, and subsequently announced a timetable for the standardization of 5G technology.

According to the IMT-2020 plan proposed at the meeting, 5G standards will be finalized in 2020. The ITU also plans to complete the 5G goal statement this year and gradually define the technical performance requirements of 5G starting in early 2016.

From 3G to 4G, users have experienced a rapid increase in network speed. So what are the differences with 5G?

>> Faster speed: Download a high-definition movie in 10 seconds

For users, faster Internet speed is the biggest feature of 5G.

It is understood that the 5G network proposed by the International Telecommunication Union has been standardized globally and will be internationally recognized. With a 5G network of at least 20Gbps, users can download a UHD movie in 10 seconds. However, the above rate refers to the transmission capacity of the entire channel, not the download speed that a single user can obtain.

The International Telecommunication Union stated: "5G networks are also capable of providing an average transmission speed of 100 megabits per second to more than 1 million IoT devices within a square kilometer." In addition, the 2018 Winter Olympics to be held in Pyeongchang County, South Korea will be the first to use 5G communications.

In addition, according to 5G research data from the University of Surrey in the UK, the mobile transmission speed of 5G networks has now exceeded 1Tbps, which is 60,000 times the current 4G network transmission speed.

Project leader Professor Rahim Tafazolli said their research has achieved dozens of breakthrough technologies, one of which can enable current wireless transmission speeds to reach 1Tbps, which is almost the speed of optical fiber.

>> Lower rates, no need to worry about losing your house

High internet speed and high fees have always been a pain in the heart of Chinese users. At the beginning of 4G commercial use, some users complained that "if you don't turn off the data for a night, your house will belong to China Mobile." With 5G, won't it be enough even if you sell your house?

In fact, this worry is completely unnecessary. Since 4G, mobile networks have become pure data networks, and data charges will become lower and lower, which is an irreversible development trend. When 5G is commercially available, network charges will be further reduced, and users' requirements for network capacity will also become higher and higher.

Here is a popular science article. Many users may not know that the 4G LTE network we are using now is only used to transmit data traffic, and voice calls still need to fall back to 2G and 3G networks. And true 4G voice calls can only be realized after VoLTE technology is popularized.

>>The battle for standardization will become a thing of the past

At present, there is no unified global standard for 5G, but one point has been generally agreed upon by all parties: in the 5G era, the world will share one standard.

As we all know, in the 2G/3G era, operators around the world used different standards to build networks. 4G has two international standards. With 5G, the world's standards will be unified, and users will no longer have to worry about changing mobile phones when going abroad.

Moreover, in the 5G era, the difference between mobile phone users’ perception of mobile networks and WIFI networks may disappear. Users can seamlessly and smoothly transition from outdoor to indoor, from mobile network to WIFI, eliminating the tedious steps of switching networks and entering passwords. They can hardly feel the “existence” of WIFI, including voice calls can also be transmitted on the WIFI network. From the user’s perspective, WiFi seems to be “dying”, but in fact it is integrated with the mobile network, so that users cannot perceive the difference between the two.

>> Everything is connected. Food, clothing, housing and transportation are all connected.

According to predictions, once 5G is fully deployed, the number of connections it provides will reach hundreds of billions, and the Internet of Everything will become a reality.

It can be said that the transition from 4G to 5G will be a fundamental revolution. Communication technology can be truly widely used in the industrial field to realize the interconnection of all things. By then, 5G will be deeply integrated with transportation, medical equipment, industrial facilities and other fields. All aspects of our lives will be connected to the Internet and realized through the network.

2G networks were designed for voice, 3G for voice and data, and 4G for broadband Internet experience. In the 5G era, the integration of computer functions and communications is ubiquitous. 5G computing power and information will surround you, and wearable devices, smartphones, tablets and other devices equipped with sensors can use applications for positioning and situational awareness, bringing a richer experience.
