3GPP's 5G-Advanced Technology Evolution from a Network Perspective Whitepaper

China Mobile, along with a bunch of other organizations including China Unicom, China Telecom, CAICT, Huawei, Nokia, Ericsson, etc., produced a white paper on what technology evolutions will we see as part of 5G-Advanced. This comes not so long after the 3GPP 5G-Advanced Workshop which a blogged about here.

The abstract of the whitepaper says:

The commercialization of 5G networks is accelerating globally. From the perspective of industry development drivers, 5G communications are considered the key to personal consumption experience upgrades and digital industrial transformation. Major economies around the world require 5G to be an essential part of long-term industrial development. 5G will enter thousands of industries in terms of business, and technically, 5G needs to integrate DOICT (DT - Data Technology, OT - Operational Technology, IT - Information Technology and CT - Communication Technology) and other technologies further. Therefore, this white paper proposes that continuous research on the follow-up evolution of 5G networks—5G-Advanced is required, and full consideration of architecture evolution and function enhancement is needed.

This white paper first analyzes the network evolution architecture of 5G-Advanced and expounds on the technical development direction of 5G-Advanced from the three characteristics of Artificial Intelligence, Convergence, and Enablement. Artificial Intelligence represents network AI, including full use of machine learning, digital twins, recognition and intention network, which can enhance the capabilities of network's intelligent operation and maintenance. Convergence includes 5G and industry network convergence, home network convergence and space-air-ground network convergence, in order to realize the integration development. Enablement provides for the enhancement of 5G interactive communication and deterministic communication capabilities. It enhances existing technologies such as network slicing and positioning to better help the digital transformation of the industry.

The paper can be downloaded from China Mobile's website here or from Huawei's website here. A video of the paper launch is embedded below:

Nokia's Antti Toskala wrote a blog piece providing the first real glimpse of 5G-Advanced, here.

Real-life 5G Use Cases for Verticals from China

GSMA have recently published a series of reports related to China. This includes the 'The Mobile Economy China' report as well as reports on ‘Impacts of mmWave 5G in China’, ‘5G use cases for verticals China 2020’ and ‘Powered by SA case studies’. They are all available here.

China currently has 1.65bn subscribers (Excluding licensed cellular IoT) which is expected to grow to 1.73bn in 2025. The report quotes 1.20bn unique mobile subscribers that is expected to grow to 1.26bn by 2025. With a population of 1.44 billion, this would be assuming everyone over 10 years has a smartphone. 2G and 3G is being phased out so only 4G and 5G will be around in 2025. This would be different for IoT.

The 5G Use Cases for Verticals China 2020 report is comprised of 15 outstanding examples of 5G-empowered applications for verticals, ranging from industrial manufacturing, transportation, electric power, healthcare, education, to content creation, and zooms into the practical scenarios, technical features, and development opportunities for the next generation technology. Every use case represents the relentless efforts of 5G pioneers who are open, cooperative, and innovative.

I have written about 5G Use Cases in a blog post earlier, which also contains a video playlist of use cases from around the world. Not many from China in there at the moment but should be added as and when they are available and I discover them.

China Telecom: An examination of the current industrial trends and an outlook of 6G

Last month I posted about the slides and videos from 6G Wireless Summit. Some of the videos were added later on. The presentation by Dr. Qi Bi, President of China Telecom Technology Innovation Center and the CTO of China Telecom Research Institute, was not shared but the video of the talk is available and it is quite insightful.

Of the many gems from the talk, I wanted to highlight couple of things. One was the ARPU, that Dr. Bi pointed out has remained the same, regardless of the technology. The other being 5G performance targets, some can be achieved, some are achievable at a price and some are just not achievable. This should be taken into account while designing 6G.


Let me know what you think

NB-IoT based smart bicycle lock

Huawei (see here and here) has partnered with China Telecom and Bike sharing company called Ofo.

ofo developed an IoT smart lock based on NB-IoT technology that lowers power consumption, enables wide coverage, and slashes system resource delays at low cost. NB-IoT lets ofo ensure it has bikes located at key locations when commuter demand is highest. Meanwhile, bikes can be unlocked in less than a second. Both improvements have greatly boosted user satisfaction.

ofo and its partners added key technologies to ofo’s own platform. These included the commercial network provided by China Telecom, and Huawei’s intelligent chip-based NB-IoT solution. When launching its NB-IoT solution earlier this year, ofo founder and CEO Dai Wei said that the cooperation between ofo, Huawei, and China Telecom is a “mutually beneficial joint force of three global leading enterprises.”

At the core is Huawei’s IoT solution, which includes smart chips, networking, and an IoT platform. The solution provides strong coverage in poor-signal areas and a network capacity that’s more than one hundred times stronger than standard terminals. The payment process has dropped from 25 seconds to less than 5, while battery life has been lengthened from 1 or 2 months to more than 2 years, saving costs and reducing the need for frequent maintenance.

ofo’s cooperation with Huawei on NB-IoT smart locks bodes well for improving the industry as whole. Huawei’s technology optimizes lifecycle management for locks, while the sensors on the locks collect information such as equipment status, user data, and operating data. They connect the front- and back-end industrial chains to achieve intelligent business management, enable the bikes to be located in hot spots, facilitate rapid maintenance, and boost marketing and value-added services.

This video gives an idea of how this works:



As per Mobile World Live:

Ofo co-founder Xue Ding said during a presentation the high power efficiency and huge capacity of NB-IoT make the technology ideal to deliver its smart locks, which are really the brains of its operations.

The company offers what is termed station free pushbike hire, meaning bikes can be collected and deposited from any legal parking spot. Users can locate bikes using their smartphone, and unlock it by scanning a barcode.

However, the process can be interrupted by mobile network congestion or if signals are weak – for example in remote areas: “Using NB-IoT, users will not be stuck because of inadequate capacity,” Xue said.
...
Xiang Huangmei, a VP at China Telecom’s Beijing branch, said the low power consumption of the NB-IoT chip in the lock means the battery will last eight years to ten years, so it will never need to be replaced during the standard lifecycle of an Ofo bike.

The NB-IoT network, deployed on the 800MHz band, offers good indoor and outdoor coverage, the VP said citing car parks as an example. One base station can support 100,000 devices over an area of 2.5 square-km.

A tale of two Smart Cities

Over the last few months I heard quite a few talks about Smart Cities. Here are two that I thought its worth posting and a very good TEDx talk at the bottom



I think we all agree that more and more people will move from rural to urban areas and the cities will not only grow in population but also in size. The infrastructure will have to grow to be able to cope with the influx of people and increased demand on services.



I guess in most developed nations we have the 1.0 Era Digital City which is long way away from the 3.0 Era Smart City.



To be a full fledged 3.0 Smart City, every aspect of our life may need to evolve into "Smart". Anyway, here is the complete presentation:

How China Telecom is Shaping the Smart City Concept in China from Zahid Ghadialy

While IoT would be important, access, big data, applications, etc. all will have a role to play.

Milton Keynes Future Cities Conference - March 2015 from Zahid Ghadialy

If you want to find out more about the Milton Keynes smart city, also see this video on Youtube. There are driverless pods and other autonomous cars which may be considered as initial step towards smart cities, see this interesting video here.

Finally here is the TEDx talk about designing these smart cities for future:
