As of 2022, there were likewise at least 80 "fusion centers" in the US, facilities where local, state, and federal police, along with for-profit companies, come together to share all kinds of data, analysis, and resources with one another.
Shades of Minority Report.
I’m sure someone is working on an App to block the spying ,LOL

“… a constellation of existing devices already hard at work tracking our every move.”
That’s a memorable quote. It’s reinforces that what (surveillance, lack of privacy), the timing (existing, and well entrenched), and the extent (pervasive).
What the quote doesn’t reference is the why, but George Orwell already helped with that.
What was once the stuff of conspiracy theories becomes mainstream news. Now lets talk about 5G tracking and targeting brain waves... welcome to a society of zombies and Manchurian candidates.
No doubt Palantir Technologies is already using this technology, linked to an international database. They already monitor everything else!
(argued that the US was quickly becoming a full-blown “surveillance society,”)
And London is BIG on that, across the pond
I heard about this a couple years ago.
There is an overlap in frequency between the microwave and infrared portions of the electromagnetic spectrum. Microwaves are generally defined as having frequencies between 300 MHz and 300 GHz, while infrared radiation spans from 300 GHz to 400 THz.
This means the upper end of the microwave range overlaps with the lower end of the infrared range.
• THz waves can penetrate materials like clothing, paper, and plastics, making them suitable for detecting hidden objects like weapons, explosives, or drugs on individuals or within packages without the need for physical contact.
• Material identification: THz spectroscopy can identify materials based on their unique “spectral fingerprints”, allowing for the identification of explosives, drugs, or other chemical compounds, according to the International Defense Security & Technology.
• Through-wall imaging: THz waves can penetrate walls, potentially enabling imaging of objects or even people located behind them, as suggested in military applications like detecting hidden tanks or militants in urban combat scenarios.
• High-resolution imaging and data transmission: THz radiation offers the potential for high-resolution imaging and high-speed data transmission, which could be exploited for surveillance or information gathering.
I wonder if it would work if your phone is in a Faraday Bag?
You mean there's actually SOMETHING from the ACLU that I agree with?

While aluminum foil is a great conductor and reflector of radio waves, it’s only effective at boosting Wi-Fi strength if the reflector is shaped correctly.
.......
This information is fed into a program called WiPrint, which creates an optimized reflector shape for your router and home in about 23 minutes. The shape can then be fed into a 3D printer.

The Wi-Fi working group developing the use of Wi-Fi to track human bodies on premises is the IEEE 802.11bf Task Group (TGbf), established under the IEEE 802.11 standards body. This group is focused on standardizing Wi-Fi Sensing, which leverages Wi-Fi signals to detect and track human presence, movement, and activities through techniques like analyzing Channel State Information (CSI). The IEEE 802.11bf specification, approved in September 2020, aims to formalize Wi-Fi sensing capabilities, enabling applications such as motion detection, gesture recognition, and biometric identification using existing Wi-Fi infrastructure. The Wi-Fi Alliance, a non-profit organization, also supports this effort by promoting interoperability and certification for Wi-Fi sensing technologies.Progress...
Wi-Fi Sensing enables diverse use cases, including smart home automation, security, health monitoring, and gesture-based control, reducing the need for dedicated sensors like radars.The standards group released Draft 0.1 in April 2022, Draft 1.0 in July 2022, Draft 2.0 in January 2023, and Draft 3.0 by December 2023. The final standard, IEEE Std 802.11bf™-2025, was published in 2025, with availability expected soon.
The amendment supports bistatic and multistatic sensing, using Channel State Information for applications like presence detection, gesture recognition, health monitoring (e.g., fall detection, heart rate monitoring), and in-car sensing. It standardizes sensing measurement exchanges during configurable sensing windows, ensuring minimal impact on data communication.
Techniques include time-of-flight (ToF), Doppler shift, and angle-of-arrival (AoA) estimation, with 60 GHz bands enabling high-resolution sensing due to shorter wavelengths. AI and machine learning (ML) algorithms, such as deep neural networks and convolutional neural networks, are increasingly used to filter noise, classify motion patterns, and improve sensing accuracy in complex environments. Research focuses on cross-band fusion (combining sub-7 GHz and 60 GHz data) for enhanced robustness.
R&D has prioritized backward compatibility with existing Wi-Fi standards (Wi-Fi 4/5/6/7), allowing sensing on off-the-shelf devices without hardware changes. Protocols minimize sensing overhead to avoid degrading data communication performance.
Experimental systems demonstrate Wi-Fi sensing for fall detection, sleep monitoring, intruder detection, and touchless interfaces. For example, prototypes achieve sub-meter accuracy for indoor localization and can detect vital signs through walls using advanced signal processing.
While the 802.11bf standard is complete, R&D continues to optimize algorithms, reduce latency, and expand use cases, with commercial deployments expected to grow as certified devices adopt the standard. Integration with edge computing and IoT ecosystems is a focus, enabling real-time processing for smart homes, healthcare, and security. Research also explores privacy-preserving sensing to address concerns about unauthorized monitoring.
Widespread commercial adoption on off-the-shelf devices is still in progress, with ongoing efforts to refine algorithms and ensure seamless integration.
A question that often arises is: “Is prolonged exposure to Wi-Fi harmful?” Scientific studies *so far do not provide substantial evidence* linking Wi-Fi radiation to cancer or serious health issues in humans. Wi-Fi signals, being low-intensity, are **generally regarded as safe** when used within standard guidelines.
The cable guy working on my set up said the Wi-Fi isn’t a good thing to have on 24 hours a day it was yanked out.
