On New Year’s Day of 2020, I read a previous Qualcomm article About 5G titled “Everything You Need to Know About 5G,” which mainly covered what 5G is, what it has, and what the future holds. I took the courage to translate, not literally, but as I understood it, only what was useful. The article is in the form of a q&A, which contains about 10 questions related to 5G.
What are the 5 g
5G is the fifth generation of mobile networks, and it will do more than its predecessors. 5G is not just about connecting people, it’s about connecting machines, objects and devices. 5G offers Gbps peak rates, ultra-low latency, and large network capacity to enhance user experiences and connect new industries.
What were the first generations of mobile networks
The previous generations of mobile networks were 1G, 2G, 3G and 4G. 1G is an analog signal, but it is easy to be disturbed and can only be used for voice. The representative works are mobile phones. 2G is a digital signal that can be encrypted and has stronger anti-jamming ability than analog signals, so 2G communication can send text messages. 3G brings mobile data and users access to the mobile Internet. 4G provides higher data transmission rates, ushering in the era of mobile Internet.
What are the benefits of 5G
With its performance and efficiency, 5G will extend the mobile web and redefine certain industries, such as education and entertainment, through connectivity. We see 5G technology as transformative as cars and electricity. The study found that the full economic impact of 5G will be realized globally by 2035 and could generate up to $12 trillion worth of goods and services.
What services will 5G offer
There are three broad categories of 5G services
-
Enhanced mobile bandwidth: 5G’s faster, more stable data rates and lower latency will lead to new immersive experiences, such as VR and AR.
-
Mission-critical communications: 5G’s high reliability, high availability, and low latency enable new services that can transform industries, such as remote control of critical infrastructure, vehicles, and medical procedures.
-
Massive Internet of Things: 5G enables the interconnection of large-scale embedded sensors by providing low-cost solutions with the ability to reduce data rates, power and mobility.
5 g how fast
5G is expected to offer peak rates of up to 20 Gbps, as required by IMT-2020, the legal name for 5G. Qualcomm Technologies’ first 5G NR modem, Qualcomm® Snapdragon™ X50, is designed for downlink peak data rates of up to 5 Gbps. But 5G isn’t just about how “fast” it is. In addition to higher peak data rates, 5G will also provide more network capacity by expanding into new spectrum, such as millimeter-wave. 5G will also offer lower latency, faster immediate response, and a more stable user experience, so data rates stay high even when the user is on the move.
When will 5G be launched
5G should be launched in 2019. A decision was made by 3GPP (the Third Generation Partnership Project, the standards body that helps define 5G) to accelerate the initial phase of 5G NR from 2019.
When I write this article, it is the New Year’s Day of 2020. On November 1, 19, three major carriers officially launched 5G packages, marking China’s official entry into the era of 5G commercial use. I believe we will be able to use 5G mobile phones soon.
The price of 5G
5G doesn’t have a price tag yet.
I checked the 5G plans of China Unicom and China Telecom, the lowest price is 129 yuan/month with 30GB data, and the highest price is 599 yuan/month with 300GB data. Mobile is about the same, but each package is a buck cheaper.
Who is pushing 5G
5G is being driven by 3GPP (Third Generation Partnership Program), which is developing the 4G LTE standard. The need to develop 5G networks is expanding beyond traditional mobile network operators to industries such as automobiles, which is why 3GPP’s new members are proliferating. At the same time, making 5G a reality requires close cooperation among 3GPP members.
The organization members of 3GPP include China’s Communications Standardization Association (CCSA), huawei and Alibaba are members of CCSA.
The difference between 5G and 4G
-
5G is a more powerful unified platform than 4G: While 4G LTE focuses on delivering mobile broadband services that are much faster than 3G, 5G is designed to be a unified, more capable platform that will not only enhance the mobile broadband experience, but also support new services like mission-critical communications and the massive Internet of Things.
-
5G uses a better spectrum than 4G: from the low band below 1GHz, to the middle band between 1GHz and 6GHz, to the high band called millimeter wave.
-
5G is faster than 4G: up to 20G/ s peak rate and 100+M/ s average rate.
-
5G has more capacity than 4G: 5G will support a 100-fold increase in traffic capacity and network efficiency.
-
5G has lower latency than 4G: reduce end-to-end latency by 10 times to 1ms.
The difference between 5G and WiFi
5G is the next generation mobile technology defined by 3GPP, while Wi-Fi is defined/standardized by IEEE and promoted/certified by the Wi-Fi Alliance.
In a word, 5G is a brand new era, and our country is making great efforts to promote it. From PC Internet to mobile Internet, the number of devices accessing the Internet has increased from 1 billion to 3 billion, increasing by 3 times. The Internet of Things conservatively puts the number of connected devices at 50 billion, an order of magnitude more than today.
The incremental growth brought by the Internet of things is bound to stimulate huge market vitality, and new giants will be born. It is a little exciting to think of Huawei’s Hongmeng System and Alibaba’s Xuantie 910. After all, in the ERA of PC Internet, Microsoft (Windows) and Intel cannot be bypassed, and in the era of mobile Internet, Google (Android) and ARM cannot be bypassed.
I hope this article can help you understand 5G and provide inspiration.
