Q: What is 5G?
Answer：
5G is the fifth generation of mobile networks. It is a new global wireless standard after 1G, 2G, 3G, 4G networks. 5G enables a new type of network designed to connect nearly everyone and everything, including machines, objects and devices.
5G wireless technology is designed to provide higher multi-Gbps peak data speeds, ultra-low latency , higher reliability, massive network capacity, higher availability, and a more unified user experience to more users. Higher performance and greater efficiency empower new user experiences and connect new industries.
Q: Who invented 5G?
Answer：
No one company or individual owns 5G, but there are several companies in the mobile ecosystem that are contributing to making 5G a reality. Qualcomm has been instrumental in inventing many of the foundational technologies that drive the industry and form 5G, the next-generation wireless standard. We are at the heart of the 3rd Generation Partnership Project ( 3GPP ), the industry organization that defines the global specifications for 3G UMTS (including HSPA), 4G LTE and 5G technologies. 3GPP is driving many important inventions in all aspects of 5G design, from the air interface to the service layer. Other 3GPP 5G members include infrastructure suppliers and component/device manufacturers, as well as mobile network operators and vertical service providers.
Q: What are the underlying technologies that make up 5G?
Answer：
5G is based on OFDM (Orthogonal Frequency Division Multiplexing), a method of modulating digital signals across many different channels to reduce interference. 5G uses the 5G NR air interface and OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and millimeter waves.
5G OFDM operates on the same mobile network principles as 4G LTE. However, the new 5G NR air interface can further enhance OFDM to provide a higher degree of flexibility and scalability. This could provide more 5G access to more people and things for a variety of different use cases.
5G will bring wider bandwidth by expanding the use of spectrum resources, from sub-3 GHz used in 4G to 100 GHz and beyond. 5G can operate in lower frequency bands (such as sub-6 GHz) and millimeter waves (such as 24 GHz and higher), which will bring extremely high capacity, multi-Gbps throughput and low latency.
Compared with 4G LTE, 5G is not only designed to provide faster and better mobile broadband services, but can also be extended to new service areas, such as mission-critical communications and connecting large-scale Internet of Things. This is enabled by many new 5G NR air interface design techniques, such as the new independent TDD subframe design.
Q: What is the difference between previous generations of mobile networks and 5G?
Answer: Previous generations of mobile networks include 1G, 2G, 3G, and 4G.
First Generation - 1G
1980s: 1G carried analog voice.
Second Generation - 2G
Early 1990s: 2G introduced digital voice (eg CDMA - Code Division Multiple Access).
Third Generation - 3G
Early 2000s: 3G brought mobile data (eg CDMA2000).
Fourth Generation - 4G LTE
2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G and 4G all gave birth to 5G, which aims to provide unprecedented connectivity.
5G is a unified, more powerful air interface. It is designed to scale to enable next-generation user experiences, support new deployment models, and deliver new services.
With high speeds, exceptional reliability, and negligible latency, 5G will expand the mobile ecosystem into new territories. 5G will impact every industry, enabling safer transportation, telemedicine, precision agriculture, digital logistics, and more.
Q: How is 5G better than 4G?
Answer: There are several reasons why 5G is better than 4G:
• 5G is much faster than 4G
• 5G has more capacity than 4G
• 5G has much lower latency than 4G
• 5G is a unified platform and more capable than 4G
• 5G Use better spectrum than 4G
5G is a more powerful unified platform than 4G.
While 4G LTE focused on delivering mobile broadband services much faster than 3G, 5G aims to be a more powerful unified platform that not only enhances the mobile broadband experience, but also supports new services such as mission-critical communications and the massive Internet of Things. 5G can also natively support all spectrum types (licensed, shared, unlicensed) and frequency bands (low, medium, high), a wide range of deployment models (from traditional and multi-hop grids).
5G uses spectrum better than 4G.
5G is also designed to take full advantage of every spectrum in the various regulatory paradigms and bands of spectrum available—from the low bands below 1 GHz, to the mid-bands between 1 GHz and 6 GHz, to the high bands known as mmWave ).
5G is faster than 4G.
5G could be much faster than 4G, offering peak data rates of up to 20 megabits per second (Gbps) and average data rates of over 100 megabits per second (Mbps).
5G has greater capacity than 4G.
5G is designed to support a 100-fold increase in traffic capacity and network efficiency. 1
5G has lower latency than 4G.
5G offers significantly lower latency, providing more immediate, real-time access: end-to-end latency is reduced by a factor of 10 to 1 millisecond.
Q: How and when will 5G impact the global economy?
answer:
5G is driving global growth.
• $13.1 trillion in global economic output
• 22.8 million new jobs created
• $265B in annual global 5G capex and R&D over the next 15 years
Through the landmark 5G Economics Study, we find that the full economic impact of 5G is likely to Achieve 2035 globally by supporting a wide range of industries and potentially enabling goods and services worth up to $13.1 trillion.
This impact is much greater than previous generations of networks. The development needs of 5G new networks are also expanding from traditional mobile network manufacturers to industries such as the automotive industry.
The study also revealed that the 5G value chain alone (including OEMs, operators, content creators, application developers, and consumers) could support as many as 22.8 million jobs, or more than one job per capita in Beijing, China. And there are many emerging and new applications that will still be defined in the future. Only time will tell the full economic impact of the "5G effect".
