802.11af
Overview
Product sourcing insights & recommendations
The IEEE 802.11af standard, commonly known as "Super Wi-Fi" or "White-Fi", operates in the TV White Space (TVWS) spectrum (54–790 MHz), leveraging unused television frequencies for long-range wireless communication ResearchgateRohde-Schwarz.
Market Trends & Status (2026)
* Niche Positioning: As of mid-2026, 802.11af remains a highly specialized niche standard rather than a mainstream consumer technology. It is primarily utilized in rural broadband, industrial IoT, and remote environmental monitoring (e.g., forest surveillance) due to its superior ability to penetrate obstacles like dense foliage and walls NatureWustl.
* Adoption Barriers: The standard's growth is severely restricted by regulatory complexity, as it requires access to a dynamic geolocation database to prevent interference with primary TV broadcasts, which varies by country ResearchgateWustl.
* Competitive Landscape: It faces significant competition from more commercially successful LPWAN technologies like LoRaWAN, Sigfox, and cellular IoT (NB-IoT), which offer lower deployment complexity GrokipediaWustl.
Technical Analysis & Comparison
| Feature | 802.11af (White-Fi) | 802.11ah (HaLow) |
|---|---|---|
| Spectrum | TV White Space (VHF/UHF) | 900 MHz (License-free) |
| Max Range | Up to several kilometers/miles | Up to 1 kilometer |
