The HKIE
webinar named “5G Era - Hong Kong and Worldwide Confirmation” was co-organized
by Control, Automation & Instrumentation Division (CAD) and held on 3rd
Nov 2020. Comparing with 4G, 5G network
support 10-time more transmission capacity, enabling up to 1 million devices to
be connected to the internet at the same time. This webinar introduced the latest concept of
5G technology and the major keys toward 5G Era.
The guest speaker was Mr. Gordon Guo (Deputy Head of Internet &
Enterprise Solution Division in China Mobile Hong Kong)
In the
beginning, Mr. Gordon Guo introduced the revolutions from 1G to 5G. He said 3G was internet of information and 4G
went to industrial internet, and then 5G entered internet of value (5G+AI, Big
Data and Blockchain).
Then he said
China was behind in 3G and 4G, but now we were at the same starting point for
5G. It had predicted the 5G industry
would drive direct and indirect economic output of 6.3 trillion CNY and 10.6 trillion
CNY in 2030, respectively.
And then he introduced
China’s “New Infrastructure” that included 5G infrastructure, ultra-high-voltage
power facilities, inter-city transport, vehicle charging stations, big data
centers, AI and industrial internet.
After that Mr.
Guo reviewed the AI development four cornerstones. Apart from algorithms, three cornerstones
that computing power, scenarios and data were supported by 5G.
Moreover, he introduced
the 5G Spectrum Resources under CMHK that included 3.3GHz, 3.5GHz, 4.9GHz and
28GHz. Those information could be found
in OFCA. Since there were two restriction
zones for 3.5GHz in Hong Kong, Mr. Guo said 4.9GHz could cover it.
After that Mr.
Guo introduced a new business model named “Slicing Network As A Service” that
could be separated as location-based, time-based and service-based slicing. There were 5 slicing level from L0 to L4 with
different definition under 5G network.
The difference
between 5G and Wifi were discussed including Range, Speed, Latency, Technology,
Modulation, Frequency and Use cases, etc.
Finally, he
briefed the 5G enabled new technologies and reshaped the new application using
5G mobile communication technology in different industries.
Lastly, Mr.
Gordon Guo mentioned different opportunities in Hong Kong through “5G + x” such
as smart logistics, tourism, hotel, medical, industrial park and finance, etc.
