Will there be a 7G?
summary
A new mobile generation like 7G should not be an automatic progression of numbering but must be justified by fundamental needs that 6G and other existing wireless technologies cannot solve. The author proposes a readiness framework to evaluate if post-6G systems require a distinct architectural shift rather than just incremental updates. This approach ensures that 7G only emerges if it provides unique coordination value, sustainability, and geopolitical viability. Ultimately, the goal is to determine if the future of connectivity is a separate generation or a broader infrastructure fabric.
key points
- The decision to create 7G should depend on whether it solves coordination problems that cannot be met by 6G-Advanced, Wi-Fi, or edge-cloud platforms.
- A readiness framework is introduced to assess demand-led needs, system-level discontinuity, trust, and circularity to avoid unnecessary standardizations.
- Potential triggers for 7G could include breakthroughs in quantum-enabled interworking, agentic network operation, and RF-native computing.

discussion skeptical
consensus
Commenters generally agree that 5G's real-world benefits are often indistinguishable from 4G for the average user, with many viewing the marketing as an exaggeration of incremental improvements. While some acknowledge better performance in high-density areas like stadiums, others argue that these gains are largely due to mid-band spectrum rather than the highly touted mmWave. There is a shared skepticism regarding the cost-to-benefit ratio for both consumers and network operators.
top insight
A detailed technical breakdown reveals that most high speeds attributed to 5G mmWave are actually delivered by C-Band (mid-band) spectrum, which is far more practical for wide-area deployment. mmWave remains a niche solution limited to extremely high-density spots like stadiums due to its poor propagation and high infrastructure cost. This distinction explains why users experience '5G' speeds without the specific technical characteristics of mmWave.
