About 5G, we should know

2020 New Year's Day, I read before the release of an article on Qualcomm 5G, entitled "Everything You Need to Know About 5G", including what 5G yes, what are the advantages and prospects for the future and so on. I venture to translate a bit, of course, I did not word for word translation, but according to their own understanding just write useful content. The article is in the form of questions and answers, probably it contains ten questions related to 5G.

1.  What is 5G 

5G is the fifth generation of mobile networks, and its role is larger than previous generations. 5G not only provides a connection between people, also provides interconnection between the machines, devices and objects. 5G provide peak rates Gbps-class, ultra-low latency and high network capacity to enhance the user experience, connecting new industry.

2.  previous generations of mobile networks is what 

Previous generations of mobile networks are 1G, 2G, 3G and 4G. 1G is an analog signal, the disadvantage is susceptible to interference, can only be used for voice, representative works are Big Brother. 2G is a digital signal, the analog signal is compared to encrypt and anti-jamming capability, so 2G ​​communication may send text messages. Bring 3G mobile data, users can access the mobile Internet. 4G offers higher data transfer rate, opening the mobile Internet era.

3.  5G What are the benefits 

5G through its performance and efficiency of the expansion of mobile networks, to redefine certain industries, such as by connecting: education and entertainment. We believe 5G technology and automobile, electric power as transformative. The study found that by 2035, all economic effects 5G will be achieved on a global scale, and may generate as much as $ 12 trillion worth of goods and services.

4.  5G what services 

5G service roughly divided into three

  • Enhanced Mobile Broadband: 5G faster, more stable data rates, lower latency will bring new immersive experience, such as VR and AR.

  • Mission-critical communications: 5G of high reliability, high availability and low latency makes possible the emergence of new services, these services can change the industry, such as: remote control critical infrastructure, vehicles and medical procedures.

  • Mass things: 5G to provide a low cost solution by reducing the data rate, the power and capacity of mobility, so that a large-scale network may be embedded sensors.

5.  5G how fast 

According to IMT-2020 (5G legal name) requirements, 5G is expected to provide up to 20 Gbps peak rate. Qualcomm Technologies first 5G NR modem Qualcomm® Snapdragon ™ X50 designed downlink peak data rates up to 5 Gbps. 5G but it is not just how "fast", in addition to higher peak data rates, 5G will provide more network capacity by expanding into new spectrum (e.g., millimeter waves). 5G will also provide lower latency, faster real-time response, and a more consistent user experience, so even if the user is moving, the data rate will remain at a high level.

6.  5G when launched 

5G should be available in 2019. 3GPP (Third Generation Partnership Project, to help define the standards bodies 5G) made a decision to begin the initial stages of 5G NR accelerate in 2019.

I wrote this article when it is New Year's Day 2020, 19 November 1 three operators formally launched 5G package, marking the formal entry into China 5G commercial era, I believe that soon we will be able to spend 5G mobile phone.

7. 5G prices 

5G has no price tag.

I checked the domestic China Unicom and Telecom 5G package, the lowest price of 129 yuan / month, 30GB traffic, up 599 yuan / month, 300GB traffic. Mobile is also similar, but each file package are a dollar cheaper.

8.  Who is pushing 5G 

5G by 3GPP (Third Generation Partnership Project) driven, 3GPP 4G LTE is a standard development organizations. 5G network development needs are expanding from the traditional mobile network operators to automobile and other industries, which is why the surge of new members of the 3GPP. At the same time, let 5G become a reality, the need for close cooperation between 3GPP members.

3GPP members include China's CCSA (China Communications Standards Association), Huawei, Ali is a member of the CCSA.

9. The  difference between the 4G and 5G 

  • 5G 4G is more powerful than a unified platform: While 4G LTE focuses on providing much faster than 3G mobile broadband services, but the 5G is designed to be a unified, more capable platform will not only enhance the mobile broadband experience, but also It will support mission-critical communications and large-scale networking and other new services.

  • 5G use of the spectrum better than 4G: from the low frequency band below 1GHz to 1GHz - 6GHz in the band, to be known as millimeter-wave high frequency band.

  • Faster than 5G 4G: providing up to a peak rate 20G / sec and an average rate of 100 + M / sec.

  • 5G capacity than 4G large: 5G will support the traffic capacity and network efficiency increased 100-fold.

  • 5G is lower than the delay 4G: The 10-fold to reduce the end to end delay 1ms.

10. The  difference 5G and WiFi 

5G is a next-generation mobile technologies defined by 3GPP, and is defined by the Wi-Fi IEEE / standardized by Wi-Fi Alliance promotion / certification.

In short, 5G is a new era, we also make great efforts to promote the country. Wu teacher before seen a share, PC Internet to the mobile Internet, the number of Internet equipment from 1 billion to 3.0 billion, an increase of 3 times. The Internet of Things conservative estimate of 50 billion networked devices, than it is today almost an order of magnitude increase.

Incremental things will inevitably bring a huge market to stimulate vitality, will be born a new giant, Huawei think of obscurity systems and brother of Ali Xuantie 910 flat head, really is a little excited. After all, the Internet PC era, Microsoft (Windows) and Intel is not around the past, mobile Internet era, Google (Android) and ARM is not around the past.

Here I hope the article will help you understand 5G, provide inspiration.
