Global Spectrum Resource Competition: Latest Developments in Wi-Fi 6GHz Band Allocation

According to international media reports, the U.S. Federal Communications Commission (FCC) has regained its spectrum auction authority under the framework of the "Big and Beautiful Act" and plans to conduct a commercial auction for the 6.425GHz-7.125GHz frequency band. This move aims to optimize spectrum resource allocation, enhance U.S. global competitiveness in mobile communications, and generate significant economic benefits.

Unique Advantages of 6GHz Spectrum

As a scarce mid-band resource with large bandwidth capacity, the 6GHz spectrum possesses the following distinctive characteristics:

  • Combines wide-area coverage with high-capacity transmission potential
  • Lower device penetration and reduced interference compared to congested 2.4GHz/5GHz bands
  • Delivers more stable and higher-quality network connectivity

Implications for the Wi-Fi Industry

Under the current saturation of 2.4GHz/5GHz bands, the available 6GHz spectrum has been compressed to 5.925GHz-6.525GHz (a nearly 50% reduction), which will directly lead to:

  • Reduced theoretical transmission rates for Wi-Fi 6E/Wi-Fi 7
  • Degraded network performance in high-density user scenarios (e.g., smart homes, IoT)
  • Limited functionality for local wireless connectivity applications

Japan/Korea

5925–6425 (7125)

Primarily LPI

Korea offers broader bandwidth (*7125MHz)

Canada

5925–7125

US-like model (AFC required)

Requires dynamic frequency coordination

Note: Wi-Fi 6E specifically refers to the existing 6GHz frequency band (5925–7125MHz) and must be clearly distinguished from 6G communication technology.

Device Power Classification Standards

  • Low Power Indoor (LPI) Devices
    • Max. Power ≤ 30dBm
    • Indoor use only
    • AFC coordination exempt
    • Typical devices: Consumer-grade routers, mobile terminals
  • Standard Power (SP) Devices
    • Max. Power ≤ 36dBm
    • Indoor/outdoor deployment permitted
    • Mandatory AFC dynamic frequency avoidance
    • Typical devices: Enterprise APs, industrial IoT equipment

Current State of Technology Applications

The globally available 5925–6425MHz (500MHz) bandwidth can currently support:
• 160MHz channel requirements for Wi-Fi 6E
• 320MHz ultra-wide channel demands for Wi-Fi 7

Leveraging Qualcomm's technology platform, QOGRISYS has successfully developed:

  1. Wi-Fi 6E modules (O2066 Series)
  2. Next-generation Wi-Fi 7 modules (O7851PM)

Extensive terminal testing confirms these high-performance modules have been widely deployed in:VR/AR systems, Industrial control systems,3D scanning equipment, Wireless storage devices, Professional signal detection instruments.
With the commencement of Wi-Fi 7 module mass production, the product line will expand to: smart TVs,set-top boxes and other consumer electronics to deliver cost-optimized connectivity solutions with superior performance.
