On May 17th, the annual World Telecommunications and Information Society Day, the Ministry of Industry and Information Technology and the State-owned Assets Supervision and Administration Commission jointly issued the “Implementation Opinions on Deepening the 2018 Special Action for Speeding up the Network to Speed ​​Up and Reduce Expenses and Accelerate the New Development of Economic Developmentâ€, which will be accelerated in 2018. The development of 5G technology industry will promote the integration of 5G and vertical industries, and prepare for 5G scale networking and applications.
In 2016, the 5G technology research and experiment will be launched; in 2018, the 5G pilot will be launched in many places; in 2020, 5G will be fully commercialized. China 5G is developing in an orderly manner according to the planning timetable and is at the forefront of the world. 5G, characterized by high speed, high reliability, low latency, and a large number of terminal networks, is entering our lives. With the advent of the 5G era, what bonuses will ordinary users receive and what preparations do they need?
5G+ internet
Ultra-fast network speed requires equipment upgrade
10GB per second, equivalent to downloading a high-definition movie in 1 second, the speed is 100 times that of 4G network... In the era of mobile Internet, "high rate" has become an important feature of 5G technology. The upgrade from 4G to 5G is not only a technology upgrade, but also a major upgrade of the user's online experience.
The experience of using 5G network to make calls is not much different from 4G, 3G and even 2G, but the online experience will be qualitatively improved. Users can easily watch high-definition movies on their mobile phones, and play VR (virtual reality) games more smoothly and realistically. Don't worry about missing important information because there is no network signal.
Laying a 5G network requires a lot of infrastructure investment. Chen Jiang, an associate professor at the School of Information Science and Technology of Peking University, said that in order to obtain a faster transmission rate, it is necessary to build a larger number of 5G base stations with higher density, base station equipment, antenna site selection, optimization and debugging, etc., which need to be higher than 4G. More capital investment. "However, 5G construction will not be completed overnight, but will be laid out in stages from hot spots such as stations and office buildings; there is no place to set up 5G, and 4G is needed to meet the needs of mobile users."
For users, it is not that simple to experience 5G networks. At present, mainstream mobile phones do not support 5G. Users want to "early adopt" and first have to change a new mobile phone. Recently, the relevant person in charge of the Ministry of Industry and Information Technology said that China is expected to produce the first batch of 5G mobile phones in the second half of 2019. If you want to upgrade, you have to wait patiently.
Many users have reported that when using 4G, because the network is too smooth, often "a few Gs are used accidentally, the phone bill is not enough." When upgrading and using 5G networks, although the unit cost of traffic charges decreases, due to faster network speeds and more access to IoT devices, the user's mobile phone traffic will increase greatly, which may increase part of the traffic charges.
5G+ travel
Unmanned driving should be safe first
Yang Xiao, a primary school teacher in Quanzhou, Fujian, often travels to and from urban and rural areas on weekends. He is both excited and embarrassed about driverless technology. On the one hand, drivers become passengers and liberate their hands; on the other hand, it is always unreliable to hand over life safety to artificial intelligence that cannot be seen or touched.
In March of this year, China Telecom, ZTE, and Baidu completed the first unmanned vehicle test based on the 5G network live environment in Xiong'an New District; Hebei Mobile, Huawei and Baoding Great Wall Motor Company completed the first 5G-V2X Automatic remote driving start and driving test. In the test, the unmanned vehicles are turning, accelerating, and braking. In the future, the unmanned vehicles will also undergo a series of tests for traffic light information, weather information, and road surface conditions.
In April this year, Chongqing announced that it will establish a smart transportation and autopilot demonstration verification and demonstration platform based on hierarchical autopilot. On May 17, a person from the Ministry of Industry and Information Technology proposed to promote artificial intelligence applications in the field of 5G and Internet of Vehicles.
Zhu Xi, deputy director of the Center for Communication Law at the China University of Political Science and Law, believes that it cannot be used because of the risks of technology. 5G technology is very important for the country's information strategic layout and key information infrastructure construction. "This technology may require a long process to achieve commercialization, and it needs to be built and tested through hardware, software and operations." 5G+Home
Smart life anti-leak privacy
Imagine standing in front of the house, but being denied access to the smart door lock; cold and hungry at home, but found that the smart rice cooker did not receive instructions, or a pot of rice; due to control failure, The air conditioner is hot and cold, the electric light is turned on and off, and the oven cannot be automatically powered off...
If the smart life is like a chicken, it is believed that many users would rather return to the past.
Insiders pointed out that the number of 5G network addresses is large, allowing everyone to have many IoT devices, and the power consumption is relatively low, which can guarantee long battery life, and the network delay is small, the probability of error is small, so it is smart home, etc. The development of the Internet of Things provides technical support.
This year, China Mobile, China Unicom and China Telecom announced that they will carry out 5G pilot projects across the country. Shanghai is the only city selected for the pilot list of the three major operators. Peng, who is studying at Fudan University, is a smart home "fan". She is very much looking forward to the pilot work in Shanghai: "A lot of smart homes in the early days were connected by Bluetooth, which was not stable. Later, it developed into a Wifi wireless connection, and the experience was greatly improved. Stable. The network channel is too important for smart homes. I look forward to 5G technology to further enhance the smart home experience."
The cyber security issues such as the leakage of user information that is constantly emerging will also threaten the 5G era. Some netizens worry that in the 5G era, many smart homes are controlled by mobile phones. If a mobile phone is lost and the mobile phone information leaks, a series of chain reactions are triggered, and the consequences are unimaginable.
Zhu Xi believes that relevant departments should step up the introduction of laws to clearly define the user information that can be obtained and the user information that cannot be obtained. Should also pay attention to the security of intelligent hardware, to avoid making these life work helpers become a "mine" of network security.
"In terms of information security protection, the advantage of 5G is not obvious. It can even be said that due to the increase in the total number of devices, people's dependence on the Internet of Things has increased, and the importance of IoT terminals is getting higher and higher, and the security problems facing 5G. It will be more prominent. This puts a more severe test on researchers and R&D engineers," Chen Jiang said.
