What is 5G?

What is 5G technology?


5G is the fifth generation mobile network. It will have a much greater role than previous generations

5G will raise the mobile network not only to interconnect people, but also to interconnect and control machines, objects and devices. It will provide new levels of performance and efficiency that will enhance new user experiences and connect new industries. 5G will offer maximum rates of multiple Gbps, ultra low latency, massive capacity and a more uniform user experience.


What are the benefits of 5G?

5G is a new type of network: a platform for innovations that will not only improve today's mobile broadband services, but also expand mobile networks to support a wide variety of devices and services and connect new industries with performance, Improved efficiency and cost. 5G will redefine a wide range of industries with connected services from retail to education, transportation to entertainment and everything else. We see 5G as a technology as transformative as the car and electricity.

Through a historical study of 5G Economy, we discover that the total economic effect of 5G will be realized worldwide by 2035, supporting a wide range of industries and potentially producing up to $ 12 billion in goods and services.

The study also revealed that the 5G value chain (OEM, operators, content creators, application developers and consumers) could only generate up to $ 3.5 billion in total aggregate revenue by 2035 and support up to 22 million jobs, or more than one I work for every person in Beijing, China. Of course, there are many emerging and new applications that have not yet been fully defined or even known today. That is why only time will tell what the full "5G effect" will be.


What services and use cases do you see for 5G?

  • Improved mobile broadband: 5G will not only improve our smartphones, but also introduce new immersive experiences, such as VR and AR, with faster and more uniform data rates, lower latency and cost per bit.
  • Mission-critical communications: 5G will enable new services that can transform industries with ultra-reliable / available low-latency links, such as remote control of critical infrastructure, vehicles and medical procedures.
  • Massive Internet of Things: 5G will seamlessly connect a large number of sensors built into virtually everything through the ability to reduce data speeds, power and mobility to provide extremely slender / low-cost solutions.
  • A defining capacity of 5G is also the direct compatibility design: the ability to flexibly support future services that are unknown today.


How fast is 5G?

5G is more than just how "fast" it is. In addition to higher maximum data rates, 5G will provide much more network capacity by expanding to a new spectrum, such as the millimeter wave (mmWave). 5G will also offer much lower latency for faster immediate response and a more uniform user experience overall, so that data speeds remain consistently high even when users move. In addition, the new 5G NR mobile network (New Radio) will be supported by the Gigabit LTE coverage base, which will provide ubiquitous Gigabit-class connectivity


What are the keys that differentiate 5G technologies?

5G is bringing a wide range of technological inventions in both the 5G NR (New Radio) air interface design and the 5G NextGen core network.

The new 5G NR aerial interface presents many fundamental wireless inventions and, in our opinion, the five main ones are:

OFDM scalable Numerology with 2n scale of subcarrier spacing

Flexible, dynamic and autonomous TDD subframe design

Advanced and flexible coding of LDPC channels

Advanced technologies of massive MIMO antennas

Advanced techniques for spectrum sharing


How does 5G work?

Like 4G LTE, 5G is also based on OFDM and will work according to the same principles of mobile networks. However, the new 5G NR (New Radio) air interface will further improve OFDM to offer a much higher degree of flexibility and scalability. To get more details about the 5G waveform and multiple access techniques, 5G will not only provide better and faster mobile broadband services compared to 4G LTE, but it will also expand to new service areas. This is enabled by many new 5G NR aerial interface design techniques, such as a new autonomous TDD subframe design; to get more detailed information about 5G and understand the specific design components of 5G NR.
