6G is being presented not simply as the next step in faster mobile internet but as a qualitative shift that would blanket populations in higher-frequency electromagnetic radiation while embedding powerful new sensing and interface capabilities into the everyday environment. According to the analysis, the technology will move beyond the millimetre-wave bands already used in 5G and into the sub-terahertz and terahertz ranges, frequencies that remain largely untested for chronic, population-scale exposure. Laboratory work on human-derived cells and tissues has already shown that terahertz radiation can produce DNA damage, genomic instability, disrupted neural stem-cell behaviour, mitochondrial dysfunction, inflammation and cell death under certain intensities and durations. These results do not yet prove that real-world 6G networks will cause widespread disease, yet they constitute biological warning signals that, the argument runs, demand rigorous long-term human studies before mass deployment. History, however, suggests the telecommunications industry is unlikely to pause for such testing; 5G itself was rolled out on the assumption of safety rather than comprehensive proof of it.
Compounding the exposure question is the architecture of 6G itself. The same radio signals that carry data are being designed to function as high-resolution sensors through a technique known as integrated sensing and communication. In practice this means networks could detect human presence, movement, posture and even certain physiological patterns through walls, creating the possibility of continuous, consent-free environmental monitoring. The denser infrastructure required by these higher frequencies, more base stations and small cells packed into urban and suburban landscapes, would make opting out of the resulting radiation field practically impossible for most people. At the same time, the ultra-high bandwidth and low latency of 6G are expected to support the next generation of implantable devices, including AI-linked neural interfaces. While such technologies are already under development, a ubiquitous high-capacity network would lower the technical barriers to scaling them and integrating continuous biological data streams into larger AI systems.
Looking beyond 6G, the same logic intensifies. Later generations remain largely conceptual, yet research trajectories point toward still higher frequencies deeper into the terahertz band or even hybrid optical systems in pursuit of extreme data rates. Propagation becomes dramatically worse at these frequencies: signals are blocked by walls, rain, foliage and the human body itself, forcing networks to become even denser, potentially room-level or device-level. The biological interaction data grow thinner the further one moves up the spectrum, while the resolution of environmental sensing improves. Extreme marketing numbers such as "7 G" are meaningless as engineering targets, yet they illustrate the direction of travel: ever denser transmitters, higher frequencies with less-understood biological effects, and sensing systems capable of finer-grained observation of private spaces and human physiology. In short, the core concerns raised about 6G: untested radiation at population scale, ambient surveillance, and the infrastructural support for invasive high-bandwidth interfaces, would not disappear with later generations; they would be amplified by the physics of the spectrum itself and by the commercial pressure to deploy ever more pervasive networks before the long-term consequences are fully understood.
