Real today 9

  • 275-450 GHz opened for fixed and mobile uses. WRC-19 added a rule (RR 5.564A) identifying 275-296, 306-313, 318-333 and 356-450 GHz for land mobile and fixed applications, with protections for radio astronomy and Earth-observation sensors. Envisaged uses are kiosk downloads, data-centre links, chip-to-chip links and short backhaul.
  • 5G millimetre waves opened 2019; Canada auctioning. WRC-19 identified 17.25 GHz of millimetre-wave spectrum for mobile (24.25-27.5, 37-43.5, 45.5-47, 47.2-48.2 and 66-71 GHz). In May 2026 Canada set rules to auction 26 GHz (25.1-27.5) and 38 GHz (37.6-40.0) blocks. These bands sit inside the first 6G study range.
  • A 300 GHz link standard already exists. IEEE 802.15.3d (2017) defines short point-to-point links in 252-325 GHz at up to 100 Gbit/s; a lab demonstration hit 100 Gbit/s in 2018. Intended uses are data centres, backhaul and close-range file transfer.
  • Above 90 GHz, walls, glass and bodies block signals. ITU measurements show waves above about 92 GHz barely get through obstacles: clear glass cut a 144 GHz signal by about 28 dB per centimetre versus about 4 dB at 28 GHz, and a person or vehicle in the path can cut it by about 25 dB. Water vapour in air also soaks up these frequencies.
  • Canada funds next-generation wireless R&D in Ottawa, Montreal. Canada co-funded the C$400 million ENCQOR 5G testbed (2018) across Ontario and Quebec, and in November 2024 put C$79.1 million into a C$634.8 million Ericsson project on 5G, cloud radio, AI and quantum in Ottawa and Saint-Laurent.
  • D-band already has rules for point-to-point links. Europe's spectrum body adopted channel plans in 2018 for fixed radio links in 130-174.8 GHz (part of the D-band) and a companion plan for 92-114.25 GHz. These are tower-to-tower links, not phones.
  • Higher frequency: more data, shorter reach. Radio waves at higher frequencies have shorter wavelengths and come in wider blocks of spectrum, so they can carry more data. But the same signal weakens faster: ITU's own formula shows moving from 2 GHz to 140 GHz adds about 37 dB of loss, thousands of times weaker, at the same distance.
  • People now sit inside machine feedback loops. In systems like an adaptive prosthetic hand, the person and the device learn from each other, so the result cannot be explained by either alone. Monitoring can even change the behaviour it later measures.
  • US opened 95 GHz-3 THz for experiments in 2019. In March 2019 the FCC created 'Spectrum Horizons' experimental licences for 95 GHz to 3 THz, lasting up to 10 years, and made 21.2 GHz available for unlicensed devices above 95 GHz.

Designed, not deployed 24

  • 3GPP finished its 6G use-case study in 2026. In March 2026 3GPP approved TR 22.870, a 590-plus page study of what 6G should be used for. It groups example use cases under AI-native 6G, sensing, coverage everywhere, immersive communication, massive IoT and industry.
  • 6G is a UN framework with six jobs. 6G's official name is IMT-2030. The UN telecom agency (ITU) approved its framework in November 2023, listing six jobs: immersive calls, ultra-reliable fast links, huge numbers of devices, coverage everywhere, AI built into the network, and the network sensing its surroundings.
  • 6G is defined by capabilities, not one frequency. Nothing in the 6G framework says 6G means one particular kind of wave. Canada's spectrum regulator expects 6G to use low, mid and high bands together, plus AI, satellites and sensing.
  • 6G networks may sense like radar. Integrated sensing and communication (ISAC) means the same radio signals that carry data also bounce off objects, so the network can detect presence, distance, angle and speed of things like drones. It is one of ITU's six 6G jobs and is being studied for the first 6G release.
  • 6G numbers are research targets, not promises. Headline figures such as 200 Gbit/s peaks or 0.1 ms latency are examples ITU gives to guide research. ITU says they apply only to some scenarios and may not all be reached at once.
  • 6G will first reuse today's 4G/5G bands. Vendors plan to switch 6G on inside existing 5G bands using multi-RAT spectrum sharing, where 5G and 6G share the same channels, and to add new mid-band spectrum alongside. Sub-1 GHz bands like 600 and 700 MHz stay essential for coverage.
  • A ten-layer test for any convergence claim. The research splits every claim into ten layers, from biology and sensors through networks, models and actuation up to governance and storytelling, and asks which layers were actually shown. An eight-rung evidence ladder runs from physical effect to proven large-scale deployment.
  • AI is designed into 6G from the start. ITU lists 'AI and communication' as a 6G job, and 3GPP's 6G study includes a common framework for using machine learning inside the network, with checks and fallback to conventional methods.
  • Above 100 GHz is feasible, but for later. A 2024 ITU report concludes mobile systems above 100 GHz are technically feasible in the future, with research clustered around 100, 140-160, 220-240 and 300 GHz. Use cases are indoor/outdoor hotspots, sensing, device-to-device links and wireless backhaul, alongside lower bands.
  • Bio-digital convergence joins five kinds of systems. The research defines bio-digital convergence as the joining of biological, engineering, information, cognitive and network systems. Canada's foresight unit uses a related three-part definition, and IEC and ISO now run a joint systems committee on the topic.
  • Canada is monitoring 7-8 GHz, eyeing D-band backhaul. ISED's 2026 spectrum outlook lists 7.125-8.4 GHz and 14.8-15.35 GHz as 'monitoring' items pending WRC-27, and puts 92-114.25 GHz and 130-174.8 GHz as possible backhaul bands to consult on later. It notes a December 2022 decision on bands above 95 GHz.
  • Cisco's 'Internet of Everything' counts people as nodes. Cisco's 2013 definition of the Internet of Everything joins people, process, data and things, and gives ingestible health sensors and wearables as ways people connect.
  • Convergence is a chain, not one gadget. Biodigital convergence happens when a body process is measured, turned into data, sent over a network, read by a model, and used to act back on the person. No single sensor, cloud or implant counts on its own; the connections are the point.
  • First 6G radio study stops at 52.6 GHz. 3GPP's 6G radio study (started June 2025, due June 2027) covers frequencies up to 52.6 GHz: today's bands below 7 GHz, the 7 GHz range and 24-52.6 GHz millimetre waves. Its scope text says frequencies above 52.6 GHz are not included.
  • IEEE frames the future as human-machine symbiosis. An IEEE initiative argues that tools are turning into autonomous systems that sense, learn and act, and that people, machines and environments will increasingly adapt to each other. Its roadmap runs from 2020 to 2040, with a horizon at 2050.
  • ITU experts agreed 20 minimum 6G requirements. In February 2026 an ITU expert group agreed a draft list of 20 minimum technical performance requirements for 6G, seven of them new. Formal approval is scheduled for 1 December 2026.
  • ITU set the official 6G framework in 2023. The UN telecom agency (ITU) approved the framework for 'IMT-2030', the formal name for 6G, in November 2023. It lists six uses: immersive communication, hyper-reliable low-latency links, massive device connections, coverage everywhere, AI in the network, and the network sensing its surroundings.
  • Keep forecast dates attached to future claims. Forecasts should carry their date and assumptions: the 2014 trillion-sensor forecast is not a current count, 2017 symbiotic-system scenarios are not deployments, and a 2018 nanonetwork design is not hidden infrastructure.
  • Many tiny antennas aim beams to recover range. To make up for weaker high-frequency signals, base stations use large grids of small antennas that steer energy into narrow beams toward each user (beamforming, massive MIMO). At 100 GHz the antenna spacing is only about 1.5 mm, so many elements fit in a small panel.
  • NSF-backed NBIC report set out human-performance convergence. A US National Science Foundation and Commerce Department report from the early 2000s surveyed how nano-, bio-, information and cognitive technologies could converge to improve human performance and health.
  • North American industry ranks which 6G uses matter. In April 2026 the Next G Alliance rated immersive, AI-enabled media and sensing-data services as high priority, digital twins as medium and multi-robot coordination as medium-low. Health was not given a priority.
  • Programmable surfaces could steer 6G radio waves. Programmable metasurfaces are panels of tiny tunable elements that can reflect, pass or shape radio waves. Researchers propose them for 6G to steer signals, sense surroundings and locate devices, and lab versions have already sent data.
  • Satellites become part of the mobile network. Since 3GPP Release 17 (frozen 2022), 5G standards already let ordinary handsets connect to satellites. The 6G study treats satellite access as an integral part of the system and looks at working even without GPS-type positioning.
  • Six choices that steer bio-digital futures. Key choices: whether core functions require the cloud, whether neural and body data enter ad markets, whether workers and soldiers can refuse, whether calibration is portable, whether models can be corrected, and whether long-term care is funded first.

Forecast 18

  • 6G technology proposals due 2027 to 2029. ITU has invited candidate 6G radio technologies to be submitted between February 2027 and February 2029. ITU aims to finish initial 6G standardization by 2030, with deployments from 2030 onwards.
  • A futurist expects 6G to be incremental, not revolutionary. In a 2024 survey of coming technologies, futurist Isaac Arthur says the interesting part is not 5G or 6G as labels but steady gains: more and faster data, lighter devices, longer range and lower battery drain, with links woven into watches and AR glasses. He picks AI as the decade's game-changer and wearables plus smart homes as runner-up.
  • Canada is preparing 6G spectrum for WRC-27. Canada's spectrum regulator says ITU's IMT-2030 work will be the basis for 6G and it is leading Canada's preparation for the 2027 World Radiocommunication Conference, which studies 4.4-4.8, 7.125-8.4 and 14.8-15.35 GHz for mobile use. A January 2026 consultation adds that 6G is anticipated in Canada 'in a few years'.
  • First 6G specifications planned to freeze in 2028-2029. 3GPP, the body that writes the actual mobile standards, approved in June 2026 a plan for its first 6G release (Release 21). The core design freezes in December 2028 and the final protocol code in March 2029.
  • First 6G specs end-2028, networks around 2030. The standards group 3GPP is only studying 6G in Release 20. Release 21 holds the first real 6G specifications: design frozen December 2028, protocol code March 2029. ITU takes candidate 6G technologies from February 2027 to February 2029, and Ericsson expects the first commercial networks in 2030.
  • New 6G mid-bands decided at WRC-27. WRC-23 (December 2023) identified more mobile spectrum, including 6.425-7.125 GHz in some regions. Under WRC-27 agenda item 1.7, countries now study 4.4-4.8, 7.125-8.4 and 14.8-15.35 GHz, without harming existing satellite and government users, for a decision in 2027.
  • No single tech future is inevitable. Chapter 20 rejects technological determinism. The path depends on six forces: technical readiness, institutional need, who pays, public trust, standards and rights, and whether failures are admitted.
  • Nobody knows who will pay for ultra-low latency. The 2019 IEEE paper notes that autonomous cars, factory cobots and haptic robot surgery benefit most from very fast networks, with XR and gaming lower on the list. How much of those markets would actually pay for low latency, and for 5G specifically, was called highly debatable.
  • Scenario: convergence led by healthcare. Wearables, implants, validated digital twins and clinical BCIs move care outside hospitals and personalise treatment. Risks include false alarms, insurer surveillance and vendor lock-in.
  • Scenario: militaries adopt convergence first. Strategic competition pushes continuous readiness monitoring, adaptive autonomy and augmentation into armed forces before civilian rights exist. Risks include coerced consent and post-service abandonment.
  • Scenarios: consumer augmentation and walled gardens. Cheap glasses, haptics, memory aids and consumer BCIs could spread through convenience, or rival vendors could lock users into one device, cloud, model and data history.
  • Scenarios: major-harm backlash or slow uneven progress. A serious breach or implant failure could trigger bans that delay good uses too. Alternatively, power limits, cost and incompatible standards could keep progress narrow and patchy.
  • Scenarios: rights-first and human-centred symbiosis. Strong privacy rules, interoperable standards and enforcement could produce trusted systems; capable machines could stay legible, bounded and user-controlled.
  • Scenarios: surveillance-first and unequal enhancement. Sensor-rich environments could expand observation faster than benefit, classifying people for risk or productivity, while costly enhancement could create a class divide.
  • The body is being redefined as an information system. The research's 'Bio-Digital Threshold' ties five streams together: bioelectric signalling, body networks, brain interfaces, digital twins and synthetic biology, all treating the human body as a data network that can be sensed, modelled and eventually modulated.
  • Tools are turning into adaptive partner systems. IEEE's Symbiotic Autonomous Systems white papers (2017-2019) argue that tools are shifting from waiting for commands to sensing context and adapting, and use the label 'human 2.0'. A 2024 Industry 5.0 article adds the label Homo Intelligentes for augmented, bionic and cyborg-like humans.
  • Vendors call 6-8.4 GHz 6G's main band. Ericsson calls 6-8.4 GHz the primary 6G range because it balances capacity and coverage and can reuse today's tower grid. It says sub-THz (about 90-300 GHz) was suggested early on but faces hard propagation problems.
  • Vendors expect trials 2028, service around 2030. Ericsson expects pre-commercial 6G trials from 2028 and first commercial services around 2030. It describes speeds of several hundred Gbit/s and sub-millisecond latency only in specific scenarios.
