6G is taking shape in standards bodies, but operators are still working to get value from 5G. Many are expanding 5G Standalone (SA), which connects 5G radio equipment to a 5G core rather than relying on a 4G core. At the same time, 5G-Advanced standards are adding features operators can introduce into their networks as equipment and devices support them.

The distinction matters for network investment. 5G-Advanced builds on specifications for networks already in use; 6G has a global framework and a standards roadmap, but no completed 6G standard or commercial network.

What does 5G-Advanced change?

The 3rd Generation Partnership Project (3GPP) develops the detailed specifications for mobile networks in successive releases. Release 18, completed in 2024, marked the start of 5G-Advanced. Release 19 builds on it, while Release 20 continues to address the needs of deployed 5G networks. These are updates to the 5G standard, not separate generations of mobile service.

The changes extend beyond faster downloads. Improvements to massive multiple-input/multiple-output (MIMO) antenna systems, which send and receive multiple data streams at once, help networks increase capacity and use radio frequencies more efficiently. 5G-Advanced also introduces more ways to use AI and machine learning to optimize radio performance, manage mobility, and reduce energy consumption. Other enhancements address device positioning and non-terrestrial networks, including satellite connectivity.

For enterprises, the specifications continue to develop Reduced Capability (RedCap), introduced in Release 17. RedCap allows less complex, potentially lower-cost 5G devices for applications that do not need smartphone-level performance, such as industrial sensors and wearables. Sidelink lets nearby devices exchange data directly, rather than routing it through a base station. 5G-Advanced enhances this capability for potential applications in vehicle connectivity and public safety.

Whether these capabilities translate into revenue depends on compatible devices and services, not just network specifications. As SDxCentral has observed, technical improvements alone do not give operators a business case.

What counts as 6G today?

The International Telecommunication Union (ITU) uses IMT-2030 as its designation for the next generation of mobile technology, commonly called 6G. Its framework for 2030 and beyond sets out broad ambitions, including wider coverage, greater efficiency, more resilient connectivity, and new capabilities involving AI and sensing. In February 2026, an ITU working party completed draft technical performance requirements for evaluating future radio technologies; those drafts still await approval by its parent study group.

The ITU sets the international framework and evaluates candidate radio technologies. 3GPP develops the detailed cellular specifications that equipment makers and operators can implement. Its Release 20 combines further 5G-Advanced work with 6G studies. The first normative 6G specifications are expected in Release 21. A study, prototype, or vendor demonstration should therefore not be mistaken for a completed standard.

Several proposed capabilities show where the research is heading. Integrated sensing and communication could let mobile infrastructure both carry traffic and detect objects or movement, for instance to track drones. Greater use of AI could help networks manage changing traffic and radio conditions. Future networks may also integrate terrestrial and satellite coverage more closely.

Additional spectrum is another open question. Higher frequencies offer room for more capacity but generally provide less coverage and are harder to use through buildings or over long distances. Upper mid-band frequencies are being explored as a possible balance between capacity and coverage; frequencies above 100 GHz are being investigated for more localized applications. Neither represents a single agreed global 6G spectrum plan.

The ITU plans to receive candidate radio-interface proposals between February 2027 and February 2029. Commercial 6G deployments are often discussed for around 2030, but their timing will depend on completed specifications, available spectrum, compatible devices, and a viable reason for operators to invest.

What should operators do now?

The practical priority is to make 5G SA and 5G-Advanced useful: improve coverage and capacity, automate operations where the gains can be measured, and develop services customers will pay for. Those investments may also provide a foundation for future networks, but operators will want a migration path that builds on existing infrastructure rather than requiring wholesale replacement.

In updated guidance issued in September 2026, the Next Generation Mobile Networks (NGMN) Alliance urged the industry to judge 6G migration options by hardware impact, implementation feasibility, and total cost of ownership. That is the clearest test of the transition: not how impressive a 6G demonstration looks, but whether the resulting network can be deployed without repeating 5G's complexity and cost.
