FCC Expands Access to the 6 GHz Band
The Federal Communications Commission (FCC) has taken an important step to boost innovation and connectivity. On December 11, 2024, the FCC announced new rules to open the entire 6 GHz band to very low power (VLP) device operations. This builds on earlier efforts to expand unlicensed use in the 6 GHz range, paving the way for exciting new technologies and applications.
With these new rules, unlicensed devices can now operate across the full 1,200 megahertz of the 6 GHz spectrum. This expansion creates opportunities for emerging technologies like augmented reality (AR), virtual reality (VR), wearable devices, and the Internet of Things (IoT).
What Are Very Low Power Devices?
VLP devices are designed to operate at low power levels over short distances while providing fast, reliable connections. They are ideal for high-data applications, including:
- Healthcare monitoring, offering real-time insights and diagnostics.
- High-accuracy navigation, vital for logistics and mapping.
- On-body wearables, enabling enhanced personal technology experiences.
The FCC’s new rules also extend the use of VLP devices to the U-NII-6 (6.425–6.525 GHz) and U-NII-8 (6.875–7.125 GHz) portions of the band. These complement existing allowances in U-NII-5 and U-NII-7.
Applications Powered by Expanded 6 GHz Access
The expanded access to the 6 GHz spectrum is expected to transform multiple industries. Some key applications include:
- Healthcare: Advanced wearables and diagnostic tools for better patient outcomes.
- Entertainment: Immersive experiences through AR and VR.
- Automotive: Smarter vehicles with enhanced in-car connectivity.
- Navigation: Improved accuracy for tracking and geospatial applications.
How the FCC Protects Against Interference
To protect existing licensed services, the FCC has introduced technical safeguards for VLP devices:
- Contention-based protocols: Devices must avoid interference by checking for open channels before transmitting.
- Power control limits: Devices must manage their output levels.
- Usage restrictions: Fixed outdoor infrastructure is not allowed, focusing VLP devices on mobile and local applications.
These rules ensure a balance between innovation and the protection of other services in the spectrum.
The Future of Connectivity
The FCC’s decision to expand access to the 6 GHz band will drive technological progress and economic growth. By laying the foundation for Wi-Fi 7 and fostering IoT development, the U.S. continues to lead in wireless innovation.
