6G Air Interface

Redesigning the wireless foundation starts with the air interface. At Qualcomm, we are purposefully shaping a new 6G air interface that unlocks more value from existing and new spectrum, extends coverage with minimal hardware changes, and raises efficiency across energy, spectrum use and implementation. AI native by design and unified for diverse use cases, it brings smarter, more adaptable connectivity to devices and experiences for the decade ahead.

Air‑Interface innovation for scaling always‑on AI

Giga‑MIMO and subband full duplex unlock upper‑midband spectrum, enabling always‑on AI, immersive experiences, integrated sensing, and pragmatic deployment toward intelligent, scalable 6G networks globally.

Unlocking more value from spectrum

We envision a 6G air interface that significantly improves spectrum efficiency and coverage without relying on network densification. Unified to support enhanced mobile broadband, fixed wireless access, massive IoT and emerging, AI-driven user experiences with a single radio access technology, the 6G air interface sets the stage for scalable, resilient connectivity that leverages both existing and new spectrum bands for a truly next-generation experience.

Refreshing the lower-band spectrum design

6G presents a once-in-a-generation opportunity to redesign the low and mid-band spectrum (e.g., frequencies below 3 GHz), fueled by the global momentum to reallocate spectrum from older network generations. A new lower-band spectrum design for 6G can benefit all ecosystem stakeholders and end users, enhancing wireless coverage, capacity and efficiency.

Enabling scalable mobile connectivity for our AI-driven future

6G will allow operators to capitalize on 3GPP’s 5G Advanced innovations, with a focus on energy efficiency, automation, infrastructure sharing, and dynamic spectrum management to improve performance and reduce costs. AI-native systems will further elevate network performance, scalability, and responsiveness. Learn more.
