For instance, some countries are also exploring advanced military applications of similar technologies, such as does India have hypersonic missile technology which relies on cutting-edge engineering and materials science, mirroring the intensity of 6G research.

Standardization and Global Collaboration

The path from research to deployment for any cellular generation is paved by international standardization. To answer, does 6G technology exist in a usable, global format, we must consider the role of standardization bodies.

The Role of 3GPP and ITU

The 3rd Generation Partnership Project (3GPP) is the primary standardization body for mobile telecommunications. It brings together telecommunications associations from around the world to develop specifications for mobile broadband technologies. For 6G, 3GPP will be instrumental in defining:

• Radio Access Technology (RAT): How devices connect to the network.
• Core Network Architecture: The backbone infrastructure of the network.
• Protocols and Interfaces: Ensuring interoperability between different manufacturers and operators.

The International Telecommunication Union (ITU), a specialized agency of the United Nations, plays a crucial role in regulating international radio spectrum and promoting global cooperation in telecommunications. The ITU will likely define the overall framework and high-level requirements for what it calls “IMT-2030” (International Mobile Telecommunications beyond 2020, which is the ITU’s designation for 6G).

Current Standardization Efforts

As of 2026, formal 6G standardization by 3GPP has not yet begun. This process typically starts once the fundamental research has matured, and the industry has a clearer consensus on the core technologies and use cases. The current activities focus on:

• Pre-standardization Research: Universities and companies are publishing research papers, running simulations, and building experimental prototypes.
• White Papers and Vision Documents: Leading organizations are releasing vision documents outlining their desired features and capabilities for 6G.
• Working Groups and Forums: Various global forums and alliances (e.g., Next G Alliance in North America, Hexa-X in Europe) are facilitating discussions and collaboration among industry stakeholders to build consensus on key requirements and technological directions.

These collaborative efforts are crucial to avoid fragmentation and ensure that when 6G eventually rolls out, it is a globally interoperable standard, much like 5G and previous generations.

The 6G Timeline: When Can We Expect It?

Given the answer to “does 6G technology exist” is currently “no,” the next logical question is, “when will it?” The development of new cellular generations follows a predictable pattern, from research to standardization to deployment.
