For enterprises, investing in Internet of Things (IoT) deployments is more than leveraging today’s technology—it’s about preparing for the future of connectivity. With 5G now widely deployed, the next evolution in wireless technology is generating buzz: 6G. Many business leaders and technologists are asking, “When is 6G coming, and how will it impact 5G and 4G LTE?”
Each mobile network generation generally follows a 10-year cycle, bringing new capabilities and features. However, the arrival of the next generation doesn’t render its predecessor obsolete immediately. Understanding the timeline for 6G and its potential impact is essential for planning enterprise connectivity strategies.

6G: Timeline and Roadmap
6G is expected to launch commercially by 2030. Research and initial requirements gathering are already underway, following the pattern of previous network generations. Standardization and specification development are scheduled between 2025 and 2029, with lab testing and pilot programs beginning in 2028, paving the way for full commercial release.
Subsequent releases, including 3GPP Release 19, will lay the foundation for 6G, with further refinements expected through Releases 20–22. Historical release patterns suggest a development cycle of 2–2.5 years per release, supporting the anticipated 2030 launch for commercial 6G networks.
How 6G Differs from 5G
While 5G has already transformed IoT and mobile connectivity, 6G promises even greater advancements. The primary technological difference lies in frequency: 6G will leverage higher bands, potentially above 100 GHz and possibly approaching 1 THz, providing faster speeds, lower latency, and higher capacity. These improvements will unlock entirely new use cases beyond what 5G currently supports.
Key Advantages of 6G Over 5G
Experts anticipate several major benefits of 6G for enterprise and industrial applications:
- Higher capacity: Utilizing sub-THz spectrum from 30 to 300 GHz.
- Enhanced coverage and reliability: Targeting 99.99999% uptime.
- Ultra-fast speeds: Potentially up to 1 terabit per second.
- Reduced latency: Supporting microsecond-level responsiveness.
- Improved spectral efficiency: Up to three times greater than 5G, reaching 100 bps/Hz.
- Expanded mobility support: Effective at speeds up to 1,000 km/h (600 mph).
Challenges Facing 6G
Despite its promise, 6G faces significant hurdles:
- High-frequency communication: Bands above 100 GHz require new radiofrequency designs and advanced semiconductor materials.
- Processing speed: Achieving terabit-per-second rates may demand optical or quantum computing solutions.
- Energy consumption: While 5G is already 90% more energy-efficient than 4G, denser 6G networks could drive power demands even higher.
Potential Use Cases for 6G
6G is expected to enable transformative applications:
- Full-sensory digital and augmented reality experiences.
- AI integration at the network edge for real-time analytics.
- Industrial IoT for smart factories and automated production.
- Tactile Internet for transmitting touch and haptic sensations.
- Autonomous vehicle operations with ultra-low latency.
- Advanced virtual healthcare solutions.
Will 6G Replace 5G or 4G LTE?
The transition from one mobile generation to the next often includes overlapping usage periods. For example, 2G and 3G networks remained operational during 4G LTE rollout and some were supported even as 5G emerged.
5G Longevity: The 5G lifecycle will likely extend well beyond 6G’s debut, potentially until 2040. However, technological advances or delays could shift this timeline.
Current Status of 6G
While 6G remains in the research phase, there are promising milestones. For example, a lab in China achieved speeds of 206.25 Gbps under controlled conditions, demonstrating the potential of terahertz connectivity, though commercial deployment is still years away.
6G Devices and Availability
Consumer and enterprise devices typically launch in tandem with network rollouts. Expect first-generation 6G devices around 2029–2031, with broader adoption following nationwide availability. Early devices are often expensive and feature-limited; enterprises typically wait for second-generation products for more cost-effective solutions.
The initial 6G rollout will likely mirror 5G’s early adoption patterns, starting in technologically advanced countries such as the US, China, and South Korea. Global availability may take years, similar to 5G’s gradual worldwide expansion.
Preparing for 6G: The Enterprise Perspective
Enterprises looking to maintain competitive advantage in IoT, industrial automation, and advanced mobile applications should plan strategically for 6G. Key considerations include:
- Assessing current 5G deployment and ROI.
- Monitoring 6G research and pilot programs to anticipate capabilities.
- Planning device procurement and phased network adoption.
- Evaluating vendor solutions with long product lifecycles and integrated management tools.
