Is 6G available in any country?

6G, or sixth generation wireless technology, is still in the very early research and development stages. While some countries and companies have begun exploring potential 6G capabilities and applications, 6G networks are not yet commercially available in any country as of late 2022.

What is 6G?

6G refers to the successor to 5G cellular network technology. While there is no formal definition or standards for 6G yet, it is expected to provide significantly faster speeds, lower latency, increased capacity, and more advanced capabilities compared to 5G and previous generations of wireless technology.

Some potential capabilities of 6G could include:

Data rates up to 1 terabyte per second
Latency reduced to 10 microseconds or less

100 times more capacity than 5G networks
Ubiquitous coverage with higher reliability
Extremely dense networks supporting over 1 million devices per square kilometer

Native support for advanced technologies like AI and edge computing

6G is still likely at least a decade away from becoming commercially available. Most experts estimate 6G may start rolling out around 2030. The key drivers leading up to its eventual launch will be the demands of new use cases and applications that cannot be sufficiently supported by 5G capabilities.

What is the current status of 6G research?

Research into 6G technology first began to gain traction around 2018, shortly after the initial launch of the first 5G specification standards. Since then, interest and momentum around 6G has been steadily building in both academia and industry.

Some key developments in 6G research so far include:

Universities and research institutes investigating potential 6G technologies, capabilities, frequencies, architectures, and use cases.
Governments launching 6G research programs and funding projects – Japan, China, Finland, and the United States are examples.

Technology companies filing early-stage 6G related patents – over 2,000 6G patent families existed globally by the end of 2021.
Telecom vendors and operators announcing 6G research collaborations and roadmaps.
The launch of the world’s first 6G research center by the University of Oulu in Finland in 2018.

Proofs-of-concept and lab demonstrations of new wireless technologies and capabilities that could potentially be part of 6G, such as terahertz spectrum networking, nano antennas, and advanced AI and ML integration.

While these efforts are helping lay the early groundwork for 6G, there is still an enormous amount of research and standardization required before 6G networks could become commercially viable. The pace of development will likely accelerate through the 2020s leading up to 6G’s eventual launch around 2030.

Which countries are leading 6G research?

Some of the countries at the forefront of early-stage 6G research include:

China – China has made leadership in wireless technology a key priority through its “6G Leadership 2030” plan. It is funding extensive 6G research projects and pioneering new technologies like terahertz networks. Major players include Huawei and ZTE.
South Korea – South Korean companies like Samsung and LG, along with universities and the government, are investing heavily in 6G research. A national 6G R&D project was announced in 2019.
Japan – Japan is targeting the launch of 6G services by 2030. Companies like NTT Docomo, NEC, and Fujitsu are collaborating on R&D efforts with universities like the University of Tokyo.

United States – The US lacks a centralized national 6G initiative but has strong research programs within universities, government agencies like DARPA, and companies including AT&T, Verizon, Apple, and Intel.
Finland – Finland aims to leverage its research strength in wireless technologies like 5G to pioneer 6G as well. The University of Oulu hosts a major 6G research program.
European Union – While individual European countries are involved, the EU is also sponsoring 6G research collaborations between academia and industry across its member states.

Other major players in 6G research include universities like the University of Surrey in the UK and NYU Wireless in the US, equipment vendors like Ericsson and Nokia, and research centers like the 6G Flagship program in Finland.

When will 6G be launched?

Most estimates expect 6G networks to begin commercially launching around 2030. The typical lifespan of a mobile generation is about 10 years before being replaced by the next generation:

1G launched in 1980

2G launched in 1990
3G launched in 2000
4G launched in 2010

5G launched in 2020
6G expected to launch around 2030

However, the research, standardization, and development timeline for 6G is still unclear compared to past generations. Some considerations include:

Research on potential 6G technologies is still in the early exploratory phase with no clear leading standards.
Regulatory bodies have not begun the process of allocating spectrum or establishing standards.
Significant technical challenges remain around areas like terahertz networking, ultra-massive MIMO, and 3D networking.

It typically takes around 10 years from the start of standards development to commercial deployment of networks.

If standards bodies begin formally drafting 6G standards by around 2025, commercial launches may begin coming around 2030-2035, with gradual expansion through the 2030s before 6G becomes dominant. However, the timeline could accelerate or slow down depending on the pace of technological progress.

What technical challenges must be overcome for 6G?

While the capabilities of 6G are expected to vastly exceed 5G, there are still significant technical obstacles that must be overcome before 6G can be commercially realized.

Some of the major technical challenges for 6G include:

Terahertz spectrum – Identifying solutions to use extremely high frequency terahertz bands beyond 100GHz for ultra-fast communication while solving issues like severe path loss.
Hardware – Developing chipsets, antennas, devices, and components that support terahertz-scale frequencies and advanced capabilities like AI integration.

Network architecture – Evolving network topology and core infrastructure to power the highly complex requirements of 6G use cases and applications.
Power consumption – Improving energy efficiency by orders of magnitude, especially for low-power devices like sensors that will exist in huge numbers.
Security – Ensuring end-to-end security as networks become increasingly open, virtualized, and software-based.

Standardization – Developing comprehensive global standards accounting for the incredibly diverse technical options.

Solving these challenges will require significant coordinated research across academia, industry, and regulators over the next decade to turn the vision of 6G into reality.

Conclusion

In summary, 6G technology is still in the very early research stage with no networks commercially deployed anywhere yet. While countries like China, South Korea, Japan, and the US are making strides in early 6G research, significant work remains to overcome technical hurdles and standardize the technology before it could become commercially viable around 2030. The exact capabilities and launch timeline for 6G are still uncertain. But its eventual arrival could bring up to 100x improvements over 5G that transform digital connectivity and enable new industries and use cases we cannot even envision today. With diligent and accelerated efforts by academia, industry, regulators, and governments over the next decade, the groundwork can be laid for realizing the full potential of 6G.
