  • Social Acceptance and Impact: The introduction of novel communication forms raises ethical concerns. Engaging with the public and stakeholders is essential to align technology with human values and address questions of data ownership and fairness.

The Dark Side of 6G

While 5G mobile communication systems are currently being deployed, discussions on 6G technology have already commenced worldwide, accompanied by initial funding programs. Despite the historical trend of introducing new generations every decade, this analysis contends that introducing 6G labels at this juncture poses significant risks. Several reasons discourage early discussions on 6G:

  1. The absence of tangible technological advancements in a potential 6G system;
  2. The adaptability of the 5G communication system through softwarization concepts, allowing for regular updates; and
  3. Widespread 6G discourse could adversely affect the deployment and evolution of 5G, introducing entirely new business cases and customer ecosystems compared to its predecessors.

Looking ahead, as we don’t view 5G as the final milestone, we’ll offer insights into the future of mobile communication systems, detached from the current mainstream discourse. There are also cybersecurity threats & privacy concerns, emphasizing the need for robust security measures to safeguard individuals from potential risks.

The Cautionary Tale of 6G: Lessons Unlearned

The world nears adopting 6G, urging reflection on overlooked lessons from 5G and 4G rollouts. These earlier technologies, despite their connectivity advancements, were deployed with little regard for environmental, ecological, and health impacts. There’s a growing apprehension that, like its predecessors, 6G is being ushered in with insufficient scrutiny towards its long-term consequences.

The deployment of 6G, much like 5G, involves the use of higher frequency bands. This escalation in frequency and the consequent electromagnetic radiation poses a significant risk, not just theoretically, but based on precedents set by earlier technologies. Studies have pointed out the potential health risks associated with prolonged exposure to EMFs, including issues like oxidative stress, increased risk of cancer, and fertility damage. Yet, the tech industry continues to accelerate its pace, prioritizing advancement over health.

Furthermore, the environmental and ecological impacts are alarming. 6G, like 5G, needs a dense transmitter network. This leads to higher energy use, posing challenges to global sustainability efforts. The potential harm to wildlife, particularly birds and insects sensitive to electromagnetic fields, is an issue that remains largely unaddressed. This technological leap forward is seemingly blind to the ecological footprints it leaves behind.

The rapid deployment of these technologies also raises questions about the ethical considerations in play. The digital divide, a glaring issue with 5G and 4G, is likely to be perpetuated with 6G. While some enjoy the benefits of cutting-edge technology, others are left in digital obscurity, widening social and economic disparities. The hasty rollout of these technologies often skips extensive public consultation. This leads to decisions without wide public awareness or agreement.

Regulating 6G: Policies and Governance

International Regulatory Landscape for 6G

Navigating the complex web of international regulations for 6G, this section provides insights into the regulatory landscape governing 6G development. The vision for a ubiquitous mobile network, providing connectivity everywhere, necessitates extensive wide area coverage. To achieve this, exploring higher spectrum ranges, especially terahertz bands, is deemed impractical for the next-generation mobile band. These bands suit the 6G vision, merging short-range radar with communication for an improved edge-to-user environment.

A supportive 6G spectrum mobile policy should prioritize the effective utilization of bands below 6GHz. This approach aims to catalyze:

  • Research into advanced spectrum sharing in bands conducive to broad coverage, potentially down to the Internet Protocol (IP) level.
  • Long-term replanning of the international spectrum allocations table, expanding adjacent mobile bands below 6GHz where feasible.
  • Parallel spectrum refarming, seamlessly introduces new technologies while phasing out older ones in existing bands, rendering next-generation spectrum auctions obsolete.
  • Preparing a sub-6GHz band for a unified network, merging satellite and terrestrial links to a consumer device.
  • Readying a common terahertz (THz) band for converging sensing (radar) and very short-range communications.
  • Development of a roadmap for transitioning to a 6G world with AI-driven spectrum sharing, possibly including regulation.
  • Advancement of AI-powered ‘sleep mode’ to unprecedented levels, simultaneously enhancing spectrum sharing, supporting net-zero carbon objectives, and addressing exposure concerns.

Ethical Considerations in 6G Development and Deployment

Navigating 6G’s ethical landscape means addressing issues beyond just technical advancements. As the evolution towards 6G unfolds, it is crucial to incorporate ethical dimensions into the decision-making processes. The following aspects merit careful examination:

Privacy Concerns

Safeguarding user privacy is paramount. 6G’s vast connectivity and sensing yield large data volumes, raising concerns about potential misuse or unauthorized access to sensitive info. Implementing robust privacy mechanisms, including encryption and secure authentication, is imperative to uphold individuals’ privacy rights.

Data Ownership and Control

The proliferation of data in 6G networks raises questions about ownership and control. Establishing clear data ownership frameworks, ensuring user consent, and preventing control concentration are key for transparency and fairness.

Environmental Sustainability

The ethical implications of 6G extend to environmental sustainability. As technology advances, it is crucial to minimize the environmental impact, considering factors like energy consumption and electronic waste. Sustainable practices, such as energy-efficient network designs and responsible disposal of electronic components, should be prioritized.

Security and Resilience

Ethical considerations encompass ensuring the security and resilience of 6G networks. Robust cybersecurity and proactive steps are crucial to prevent harm and protect users.

The Race to 6G Continues

In pondering 6G’s future, we’re at a critical juncture, akin to 5G and 4G. Promising tech mustn’t neglect health and environmental concerns. Lessons from previous generations of wireless technology are not merely cautionary tales but essential guides for a more responsible approach.

In developing and deploying 6G, we must balance progress with ethical considerations, privacy safeguarding, and protection of all biological objects. Awareness of potential environmental impacts, security risks, and societal disparities is crucial. This urges aligning tech advancements with global well-being, ensuring 6G benefits society and protects our planet’s health.
