A company in Taiwan recently presented a developing WiFi tech that can be used to monitor your location, heart rate, breathing patterns, sleep cycles, and much more.
The company’s techie bossman, Doctor Tzi-cker Chiueh, claimed that, “Channel state in modern Wi-Fi is susceptible to minor environmental changes.” These tiny changes can be used with an algorithm he helped create that can do breathing rate estimation at 95 percent accuracy over 5 meters, and heart rate measurements at 83 accuracy at a 1 meter distance.
As it turns out, using WiFi sort of like radar is nothing new; it’s been around for a number of years now.
But there are two little details that nobody is mentioning which could make this “WiFi Sensing” much, much more common in the years to come…

There are hundreds and hundreds of studies showing that our wireless wonderland of EMF is not good for our health.
But you might ask: Well, HOW?
When we say “EMF”, we’re talking about many different types of electromagnetic waves, different frequencies, different power levels, and so on.
How could it possibly work?!
It turns out that the answer may very well be in our DNA!

You might think Ethernet is on its way out the door. After all, everyone just uses WiFi, right?
WRONG! For the past couple of years, my most popular video on YouTube has been:
No more WiFi: How to wire your house for Internet
Published in September of 2019, the video has garnered over 1.6 million views, and it’s still going strong.
Obviously, many people want Ethernet – contrary to popular belief. That’s good, because it’s only going to get better…

By now, you probably know that there’s enough scientific doubt about wireless tech.
But how do you get people to listen?
It’s easier than you think:
You just apply simple common sense!

So, you’ve gone wired and are enjoying the speed, stability, and privacy of Ethernet.
One problem: There’s no button to turn off WiFi on your ISP’s router/modem!
What to do?
Why, hack it, of course!

Most people probably don’t even notice the actual speed of their internet connection. If it ‘goes fast’, they’re happy.
What many folks don’t realize is that they may be wasting a large chunk of their very high speed net connection.
If you use even newer flavors of WiFi, chances are you aren’t taking full advantage of the connection you’re paying for! Heck, even with Ethernet, your download speeds may be lower than you think.
So, how do you tell?

Microwave ovens that you use to cook food operate at a frequency of 2.45 GHz.
This is the same radio band where one finds WiFi, Bluetooth, and so on.
So, why is everything lumped into this one chunk of the frequency spectrum? Is there something particularly magical about 2.4 GHz?
It turns out that there is a common misconception about this frequency and water.
The truth, however, is far more mundane…

First of all, it’s finally happened: 2.5 Gbps Ethernet is HERE!
It’s already rolling out, and consumer-grade 2.5 gig switches will arrive shortly.
The other big news is the unveiling of WiFi 6E.
A new flavor of WiFi 6, the 6E variant adds the 6GHz radio band and speeds of up to 11Gbps… Or so they say.
So, the question is: stick with wired, or go WiFi 6E wireless? Which is faster?

In this episode, I answer some questions and comments left on my various 5G videos – especially 5G is just the tip of the iceberg.
Since I posted that video 2 years ago, it has received almost 6000 comments. Many are informative, supportive, and heartening.
And then there are the “other” comments…
Join me for a deep dive QnA – and a bit of fun!
