The global mobile landscape is on the cusp of a major transformation, with sixth-generation (6G) mobile technology expected to account for over five billion connections worldwide by 2040.
This projection comes from the Global System for Mobile Communications Association (GSMA) in its latest Vision 2040 report, which outlines spectrum needs and anticipated adoption trends for next-generation networks.
Although the shift to 6G promises unprecedented capabilities, experts caution that the rollout will be gradual. Current 4G and 5G networks are forecasted to remain foundational to global connectivity for years, supporting approximately two billion 4G and three billion 5G connections through 2040
6G Connections and Global Adoption Patterns
The GSMA report indicates that the deployment of 6G connections will be uneven across regions. Advanced markets such as China, Japan, South Korea, the United States, Europe, and India are expected to achieve near-full penetration by 2040. Conversely, low- and middle-income regions may experience slower adoption due to limited spectrum availability, infrastructure constraints, and investment challenges.
“The adoption of 6G connections will vary significantly, with advanced markets leading the way while other regions gradually catch up,” the report noted.
“Existing 4G and 5G networks will continue to play a critical role in bridging connectivity gaps during this transition period.”
This phased rollout underscores the importance of maintaining robust infrastructure for current networks while preparing for the future of 6G connections.
Policymakers and network operators are being urged to develop long-term spectrum strategies to avoid congestion and ensure seamless service quality.
Driving Factors Behind 6G Connections Growth
The report highlights that future demand for 6G connections will not be driven solely by higher download speeds.
Emerging applications, including AI-driven services, immersive communications, and digital twins, will necessitate ultra-low latency of under 10 milliseconds and expanded spectrum channels to reduce transmission delays.
Moreover, evolving user behaviour is expected to shape network usage patterns. Currently, about 10 percent of mobile users account for 60 to 70 percent of total network traffic.
By 2040, such high-intensity consumption is projected to become standard as digitally native generations age, further emphasizing the need for efficient 6G connections infrastructure.
Geography will also play a decisive role in spectrum demand. Analysis by the GSMA shows that 83 percent of mobile traffic occurs in urban areas, which make up only five percent of landmass.
Dense urban locations can experience traffic intensity up to nine times higher than other cities and nearly 700 times higher than rural regions, highlighting the risk of congestion if spectrum allocation does not keep pace with 6G connections growth.
Policy and Regulatory Considerations
The GSMA report stresses the need for forward-looking spectrum policies. Governments are encouraged to prepare for critical decisions at the World Radiocommunication Conference (WRC-27) in 2027, which will set the framework for harmonizing new spectrum bands to support next-generation mobile evolution.
“Delays in spectrum allocation could hinder the rollout of 6G connections, particularly in densely populated regions,” the GSMA warned.
“A balanced approach, investing in current 4G and 5G networks while preparing for 6G, is essential to meet growing connectivity needs.”
Regulators are also being urged to coordinate with network operators and technology providers to ensure that infrastructure development aligns with projected growth in 6G connections.
This proactive approach is vital for supporting innovation, maintaining network reliability, and expanding digital inclusion worldwide.
Implications for Businesses and Consumers
The expansion of 6G connections will create transformative opportunities across sectors, from smart cities and autonomous transportation to healthcare, finance, and education.
Enterprises will be able to deploy real-time AI analytics, immersive virtual experiences, and highly secure IoT networks, driving efficiency and innovation at an unprecedented scale.
For consumers, 6G connections promise faster, more reliable mobile internet, low-latency services, and enhanced digital experiences. However, the report notes that affordability, device compatibility, and equitable access will be critical challenges for achieving broad adoption, particularly in developing markets.
While the vision of five billion 6G connections by 2040 is ambitious, the GSMA emphasizes that the transition will be evolutionary rather than immediate.
Policymakers, regulators, and industry stakeholders must work collaboratively to manage spectrum allocation, ensure infrastructure readiness, and maintain robust 4G and 5G networks as a foundation for future growth.
As 6G connections begin to reshape the global digital ecosystem, forward-looking strategies will be essential to unlock the technology’s full potential, promote connectivity equity, and support a sustainable, innovation-driven future.
