VLP (Very Low Power)
VLP (Very Low Power) refers to a class of Wi-Fi devices operating in the 6 GHz band with extremely low transmission power. These devices are designed for short-range, portable applications and are exempt from Automated Frequency Coordination (AFC) due to their minimal interference potential.
Scope and Application
Use cases: Augmented/Virtual Reality (AR/VR), wearable electronics, portable streaming, and battery-powered IoT
Typical operation: Indoors and outdoors, handheld or body-worn
AFC requirement: Not required
Regulatory status: Currently authorized in the United States; adoption in other regions under review
Frequency Allocation
United States: Full 6 GHz band (5925–7125 MHz), spanning U-NII-5 to U-NII-8
Other regions: Availability may be restricted or pending approval
Key Technical Requirements
Maximum EIRP: Up to 14 dBm total and 5 dBm/MHz power spectral density (PSD)
Antenna design: Integrated, fixed antennas only; external antennas not permitted
Mobility: Devices are intended for mobile or on-body operation and typically battery-powered
Certification and Compliance
Certification: Mandatory under FCC rules (and required in any future markets)
Device classification: Must be explicitly declared and tested as VLP
Labeling: No universal requirement; may depend on regional or use-case-specific rules
Lifecycle Relevance
Regulatory benefit: Enables portable 6 GHz operation without AFC constraints
Design constraints: Strict power and antenna limits must be integrated early in development
Market access: Currently limited to the U.S.; regulatory progress in other countries is ongoing
