WiFi and wireless tech can now track you and "see" you—whether you're inside your home, at a public venue, in a doctor's office, or walking down the street.

This is real. The wireless signals coming from the WiFi router you own right now already have the ability to track where you are and where you're going inside your own home.

Very soon, this "Passive Sensing Technology" will be able to detect individuals—even in a crowded public space—right down to their heartbeat. At home, it will be able to pinpoint exactly which family member is in which room.

• The new WiFi is also a radar. The new WiFi standard, called 802.11bf, essentially turns your WiFi router into a radar system.
• The EMFs from your WiFi bounce off you and the system identifies you: Anything moving through a space where this Passive Sensing Technology is operating disrupts the EMF field, allowing the system to build a detailed picture of who you are.
• Don't rush out to upgrade your WiFi or even your smartphone: Avoid upgrading your WiFi router or smartphone unless necessary. The newest devices are the most likely to have 802.11bf and passive sensing technology built directly into the hardware.
• Take control and shut it off. If your router has motion sensing features, turn them off in your provider's app. Better yet, switch off your WiFi when not in use, or hardwire your home with Ethernet cables to eliminate wireless tracking entirely.
• It's already here: MOST IMPORTANTLY, if you get your internet from Verizon, Xfinity WiFi, or Google Nest Home, this tracking is happening NOW.

How Does WiFi and Wireless Sensing Technology Work?

The bottom line: WiFi signals (EMF) are constantly transmitted from a router to connect to your devices. When a living body steps into the path of those signals, the wave pattern is disrupted.

Some of that EMF bounces off your body, while some is absorbed directly into your tissue.

As signals bounce around, some arrive micro-seconds earlier or later. As the overall signal pattern is disrupted, it gets tracked. Routers capable of motion sensing analyze these tiny data shifts—known as Channel State Information (CSI)—to detect movement without needing a single camera.

Here's an important point: CSI is a standard feature baked into the WiFi protocol itself—not something that requires extra hardware beyond what many existing WiFi 6 routers already possess. It's not an add on or an option.

If you want to dig really deep, check this out: On top of CSI sensing—which was officially formalized as the IEEE 802.11bf WLAN Sensing standard—technologies like MIMO, (Multi-Input, Multi-Output) Beamforming, and AI are being combined to dramatically enhance motion tracking.

For example, many WiFi 6 routers use MIMO for beamforming, which works by measuring how radio signals bounce around your space to focus and optimize connection quality. But that exact same data can be repurposed to pinpoint where you are and how you're moving. Adding AI to the mix allows systems to process this raw data and create a detailed picture of your home environment—completely camera-free.

Will there be a test on this? Absolutely not!  It's my job to get deep, deep, deep into the weeds and come out with actionable information for you--which is coming right up.

Some use the new 5G EMF called the Millimeter Wave

Some of the actual elctromagnetic frequencies used for sensing are the standard WiFi frequencies: 2.4 or 5 Ghz. The Google Nest Home and many other consummer products are starting to use the millimeter or mmWave to reflect off our bodies, often using specifically 60 GHz mmWave radar.   So you'll be welcoming that lovely millimeter wave right into your home.

Sensing Technology or Not: Your Body is Absorbing And Reflecting WiFi Signals Today--But Some Sensing Will Make it Worse

Whenever WiFi's on- it's sending out a signal continuously, hoping to connect to a device.  When it does and you're in the middle of it, you're being exposed to EMF.  This is exactly why there's no WiFi in my house and why I encourage you to at the very least, turn your's off when you're not using it.   EMF exposure is linked to oxidative stress, infertility, anxiety, loss of sleep, headaches and even cancer.  Find out how it's affecting you here in our continually updated EMF GUIDE

The new 802.11bf standard I talked about earlier also defines dedicated sensing sessions.   This is where a router can transmit specific sensing frames — sometimes called "null data packets" or "sounding frames."  These are extra EMF transmissions coming from the WiFi simply to probe.  This means additional EMF exposure over and above the regular signals your router uses to deliver internet to your phones, laptops, and smart devices. Consequently, the biological impacts of living amidst these man-made, data-carrying radio waves and magnetic fields will only increase.

1. Hold off on upgrading needlessly: The newer the phone or router, the more likely it has sensing features baked in. Even if you don't enable these features, the hardware is present and could potentially be utilized by your Internet Service Provider or third parties.
2. Speak up in public spaces: Share this information with your workplace, local school, or bank, and advocate for keeping WiFi Sensing features turned OFF in public spaces. No WiFi Sensing!
3. Manage your current equipment: Many existing routers already support motion tracking using MIMO, beamforming, and CSI—even without 6G, mmWave, or Terahertz tech. If your router is sensing-equipped, disable the sensing feature, switch to a hardwired connection, replace it, or strictly limit when it is powered on.
4. Protect your sleep space: If you live in an environment with active WiFi motion tracking, I highly recommend sleeping under an EMF Protection Canopy. Our luxurious, natural cotton canopy blocks standard RF signals. (Note: High-frequency mmWave signals operate differently, so if your router explicitly uses mmWave radar, you will still want to disable or distance that router).

Honestly, this new technology is like a Tech Toxin DOUBLE WHAMMY!

Not only are you having to deal with EMFs from WiFi--now you're having to cope with EMFs that can track you and invade your privacy!  Here's what you need to do to protect your privacy and your peace of mind:

 

1. Use a router you control: Choose an independent router—like our Tech Wellness Low EMF WiFi—running open-source firmware rather than using ISP-provided equipment.
2. Keep routers out of private spaces: Never place a router in bedrooms or private spaces (and definitely not bathrooms!).
3. Consider absorptive materials: Use protective solutions in sensitive areas, like our beautiful canopy.
4. Monitor firmware updates: Check update release notes for newly added "sensing," "presence," or "motion" features.
5. Reduce unnecessary coverage: Avoid placing mesh nodes in every single room. Ask yourself: Do we really need WiFi coverage in every corner of our home? (Like bathrooms and bedrooms???)

Our Specially modified Low EMF WiFi Router will reduce your EMF by 90% and it will NOT be able to track you.  Ever.

I connect using our Hard Wire Kit—good old-fashioned, faster, and far more reliable Ethernet cables! In fact, this entire article was researched and written without using any wireless signal whatsoever. 🔥

Stay Safe and Be Well!
