Wi-Fi sensing is now a standard, not a research curiosity

For years, the idea that a room could sense you through its Wi-Fi sounded like a lab demo: clever, fragile, and a long way from anything you would put in a home. That framing is now out of date. In October 2024, the IEEE froze 802.11bf, a formal amendment to the Wi-Fi standard whose entire purpose is sensing.

What a standard actually changes

802.11bf does not invent Wi-Fi sensing. It does something quieter and more important: it agrees on how it should work. The amendment defines how devices use Channel State Information (the fine-grained way a signal is reshaped as it crosses a space) to detect presence and motion, and it does so while staying backward-compatible with the Wi-Fi already in the wall.

A standard is what turns a technique into an ecosystem. It tells chipmakers, router vendors, and platforms that this is a direction worth building toward, with a shared vocabulary instead of a hundred incompatible experiments. The thing Stillsense does is no longer a bet against the grain of the industry. It is the grain.

Where Stillsense sits

We have been building on commodity Wi-Fi sensing because it was the right architecture, not because it was fashionable. A global standards body arriving at the same place is a useful confirmation, not a change of plan.

The standard describes a broad spectrum of sensing, including physiological signals like breathing and heart rate. We are deliberate about what we claim today: Stillsense detects presence, motion, and bed-exit, with fall detection, breathing-rate, and heart rate not yet independently validated, never a safety-grade or clinical guarantee. The standard widens the road ahead; it does not change what we are willing to promise now.

That discipline is the point. Sensing becoming standard is exactly why being precise about it matters more, not less.
