CES Seminar – When Trump loves in 5G and 6G

CityU Eminence Society (CES) University Collaborative Project Work Group organized a seminar named “When Trump loves in 5G and 6G” and then visit the State Key Laboratory of Terahertz and Millimeter Waves. Before the seminar, CES work group members took a photo with Dr. Wong Hang for memory.

In the beginning, Mr. Week Wong (Chairman of CityU Eminence Society) gave welcome speech and he also introduced CityU Eminence Society (CES) to all participants.

Dr. Wong Hang (Associate Professor, Department of Electrical Engineering, CityU) was our guest speaker and he shared knowledge and development trend of 5G, as well as, 6G idea. His talk focused on Investment, Technology and Leading Country.

Firstly, Dr. Wong briefed the history of telecommunication from 1G to 5G. 1G used AM signal, 2G changed to digital and then 3G would use internet, until 4G could use mobile for World Wide Web.

Then he introduced 5G technology and advantages to us. It is the first attempt at microwave (4G: ~2GHz) and millimeter-wave (5G: <6GHz) spectrum. Millimeter-wave is faster than microwave one order of magnitude (x10). He also explained 5G in terms of Data Rate, Latency, Mobility, Connection Density, Spectrum Efficiency and Antenna Access.

And then Dr. Wong reviewed the milestone of mobile from 1G to 5G. He pointed out Siemens phone was disappeared because they selected technology to make phone as small size as possible but it was high energy consumption.

Nokia kept their size because of their research on the relationship between phone size and radiated power of antenna. After that all phone size would not small than their phone in 1999. After that he described the global 5G market and predicated it to grow exponentially by 2025. There would be five domain markets and they were “5G Chipset”, “5G Equipment and Tester”, “5G Base Station”, “5G Data” and “5G Applications and Service”.

Dr. Wong quoted news that “Donald Trump says he wants the US to lead in 5G and even 6G wireless technology. Then he reviewed top brands of companies for 5G preparation in four market segments and they were Infrastructure, Service, Mobile and Chipset. He said USA only service was lag behind but still leading in the infrastructure.

Finally, he discussed 5G on vehicle and showed the importance of 5G in the auto industry for self-driving. One of video was showed “Pioneering use of glass-mounted antenna for 5G connected vehicles” and it was amazing! For autonomous driver, there are separated into 5 levels below.

Level 1: Driver Assistance

Level 2: Partly Automated Driving (recent technology)

Level 3: Highly Automated Driving

Level 4: Fully Automated Driving (5G/6G network)

Level 5: Full Automation (No driver)

Lastly, Dr. Wong said 5G is coming in 2020 and next generation would be in 2030. 6G is three-dimensional communication using Satellite and named “Internet over Satellite (IoS)”.

Q&A:

For Smart City, Dr. Wong said it was just in the beginning and HK could chase the behind easily in terms of technology. Then we discussed some business opportunities on 5G. Dr. Wong said investment in infrastructure and chip would be high return. On the other hand, mobile is terminal device which is not the most return on investment in terms of 5G. IoS was the old concept which happened in Motorola long time ago. Dr. Wong said technology readiness did not mean market readiness.
