Next G Alliance looks to 6G

 A new Next G Alliance, organized by ATIS, has been formed to advance North American mobile technology leadership in 6G and beyond over the next decade. 

Founding members include AT&T, Bell Canada, Ciena, Ericsson, Facebook, InterDigital, JMA Wireless, Microsoft, Nokia, Qualcomm Technologies, Samsung, TELUS, Telnyx, T-Mobile, UScellular and Verizon.  

The Next G Alliance seeks "to encompass the full lifecycle of research and development, manufacturing, standardization and market readiness." 

The group says it will initially focus on three strategic actions:

  • Develop a 6G national roadmap that addresses the changing competitive landscape and positions North America as the global leader in R&D, standardization, manufacturing and adoption of Next G technologies.
  • Align the North American technology industry on a core set of priorities that will steer leadership for 6G and beyond to influence government policies and funding.
  • Identify and define the early steps and strategies that will facilitate and lead to rapid commercialization of Next G technologies across new markets and business sectors and promote widescale adoption, both domestically and globally.

“As countries around the globe progress ambitious 6G research and development initiatives, it is critical that North American industry steps forward to develop a collaborative roadmap to advance its position as a global leader over the next decade,” said ATIS President and CEO Susan Miller. “The work of the Next G Alliance delivers just that – from research to commercialization – and it is setting the foundation for a vibrant marketplace for North American innovation in future generations of mobile technology.”

Samsung’s 6G White Paper

Samsung published a whitepaper outlining its vision for 6G, including technical and societal megatrends, new services, requirements, candidate technologies and an expected timeline of standardization.

Samsung is predicting that the completion of the 6G standard and its earliest commercialization date could be as early as 2028, while mass commercialization may occur around 2030. Both humans and machines will be the main users of 6G, and 6G will be characterized by provision of advanced services such as truly immersive extended reality (XR), high-fidelity mobile hologram and digital replica.

“While 5G commercialization is still in its initial stage, it’s never too early to start preparing for 6G because it typically takes around 10 years from the start of research to commercialization of a new generation of communications technology,” explained Sunghyun Choi, Head of the Advanced Communications Research Center. “We’ve already launched the research and development of 6G technologies by building upon the experience and ability we have accumulated from working on multiple generations of communications technology, including 5G. Going forward, we are committed to leading the standardization of 6G in collaboration with various stakeholders across industry, academia and government fields.”

Candidate technologies under the 6G umbrellas could include the use of the terahertz (THz) frequency band, novel antenna technologies to enhance the coverage of high frequency band signals, advanced duplex technologies, the evolution of network topology, spectrum sharing to increase the efficiency of frequency utilization and the use of AI in wireless communications.

NTT DOCOMO aims for 6G in 2030

NTT DOCOMO published a white paper outlining its ambition to launch 6G commercial services by 2030.



The white paper summarizes the related technical concepts and the expected diverse use cases of evolving 5G and new 6G communication technologies, as well as the technology components and performance targets. DOCOMO has 6G research and development programs underway. In 2018, the company conducted successful radio wave propagation experiments at frequencies of up to 150 GHz, levels which are expected to enable the much faster and larger-capacity communications that 6G will require.

DOCOMO said it will continue to enhance the ultra-high-speed, large-capacity, ultra-reliable, low-latency and massive device-connectivity capabilities of 5G technology. It will continue its research into and development of 5G evolution and 6G technology, aiming to realize technological advances including:
  • the achievement of a combination of advances in connectivity, including ultra-high speed, large capacity and low latency
  • the pioneering of new frequency bands, including terahertz frequencies
  • the expansion of communication coverage in the sky, at sea and in space
  • the provision of ultra-low-energy and ultra-low-cost communications
  • the ensuring of highly reliable communications
  • the capability of massive device-connectivity and sensing

German researchers investigate THz frequencies for 6G

Researchers at Rohde & Schwarz, the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI and the Fraunhofer Institute for Applied Solid State Physics IAF are testing the terahertz (THz) frequency band for possible use in the 6th generation wireless mobile communication (6G).

The collaboration has resulted in a wireless transmit and receive system operating between 270 and 320 GHz, with further frequency extensions for potential 6G bands already in preparation. Wide contiguous frequency blocks can only be found at sub-THz and THz bands, i.e. in the frequency range above 100 GHz.

Dr. Michael Schlechtweg, Head of Business Unit High Frequency Electronics at Fraunhofer IAF, said, "As one of the first global providers of chipsets and electronic components capable of reaching already now the high frequencies required by 6G, we are collaborating with valued partner Rohde & Schwarz at the very cutting edge of technology. IAF appreciates the mutually highly beneficial cooperation and is happy to continue exploring new innovations with Rohde & Schwarz."

NTT and Tokyo Institute of Tech achieve 100 Gbps using terahertz band

NTT and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have achieved a record 100 Gbps wireless transmission data rate.

The researchers implemented a mixer circuit that applied a unique proprietary high isolation design technology with an Indium phosphide high electron mobility transistor (InP-HEMT). NTT said this process enlarged the transmission bandwidth, which is a problem in the conventional 300 GHz band wireless front end. It also improved the signal-to-noise ratio (SNR). In addition, using this we realized a 300 GHz band wireless front-end module, and we achieved wireless transmission of 100 Gbps (gigabits per second).

NTT said future work will extend to multiple carriers by making use of the wide frequency band of 300 GHz band, and using spatial multiplexing technology such as MIMO and OAM. The researchers hope to produce an ultra high-speed IC that enables wireless transmission of 400 Gbos.

NTT employs Orbital Angular Momentum multiplexing for 100G wireless

NTT successfully demonstrated the first use of Orbital Angular Momentum (OAM) multiplexing to achieve 100 Gbps wireless transmission.

The laboratory tests combined OAM multiplexing with Multiple-Input Multiple-Output (MIMO) technology and carried the signals a distance of 10m.

NTT said a key feature of OAM is that electromagnetic waves can be superposed and separated because phase rotation occurs on the vertical plane in the propagation direction.  An electromagnetic wave with phase rotation cannot be received without a receiver having the same number of phase rotations at the time of transmission. NTT developed a transceiver operating in the 28 GHz band capable of OAM transmission. NTT also developed signal processing technology capable of handling 11 data signals simultaneously each at a bit rate of 7.2 to 10.8 Gbps, thereby achieving large-capacity wireless transmission at a total bit rate of 100 Gbps.

NTT believes the technology holds promise for achieving large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G.
