Samsung's 6G Spectrum Whitepaper Discusses Candidate Bands

Earlier we wrote about Samsung Electronics hosting their first-ever Samsung 6G Forum (S6GF) online. Back in May, Samsung also unveiled their 6G Spectrum White Paper and 6G Research Findings:

6G would require spectrum with ultra-wideband contiguous bandwidth ranging from hundreds of MHz to tens of GHz to enable new services such as high-fidelity mobile holograms and truly immersive extended reality (XR) that are characterized by ultra-high speed communications and large amount of data. There is also growing demand for greater coverage. In response to these requirements, Samsung proposes considering all available bands for 6G, from low-band under 1 GHz, to mid-band in the 1-24 GHz range and high-band in the 24-300 GHz range.

It also highlights the importance of securing new bands for commercial deployments of 6G, as 5G networks will still be operational when the 6G deployment starts. The mid-band within the 7-24 GHz range is a candidate that can support faster data speed and reasonable coverage. The sub-terahertz (sub-THz) band in the 92–300 GHz range is being considered for support of ultra-high speed data rate. The white paper also mentions the refarming of existing bands used for 3G, 4G and 5G networks to 6G operation as another way to obtain all the spectrum necessary for 6G. In addition, it notes that research on forward-looking regulations and technologies on spectrum utilization is essential to provide efficient and flexible support of 6G and other services with the limited spectrum.

The whitepaper is available here. Quoting from the preface:

Samsung Research has published the 6G vision white paper entitled “6G, The Next Hyper-Connected Experience for All.”, where we presented our vision that 6G will provide an ultimate experience for all through hyper-connectivity involving humans and everything. As a follow-up of the vision white paper, we in this white paper explore how to enable 6G to be realized around 2030 from a spectrum’s perspective.

Sub-THz is a new frontier of exploration as we try to understand what is possible in addition to the low, mid and high bands, as the industry develops 6G targeting initial deployments around the year 2030 onwards. In this 6G spectrum journey, Samsung looks forward to working with industry, regulators and academia from around the world to help realize the global 6G vision and bring benefits to the world’s citizens and environment.

6G is facing a formidable challenge to be significantly greater than evolved 5G, serving 7 billion citizens in all locations around the world as well as 500 billion devices and things. To do this will require new spectrum from sub-1 GHz to sub-THz, in addition to the continued reuse of existing spectrum in the low, mid and high bands. Global cooperation will also be required to develop and realize the spectrum vision.
