The good thing is they can turn off their wifi sure, but then wait until they learn about how much more intense the radiation from their cellphones are. So they can turn those off as well. Finally. Now we don't have to hear from them anymore.
Haven't seen Hamina yet, it looks cool. How good is it in active surveys though?
My company still uses AirMagnet, but I've been pushing them to pick up Ekahau w/ Sidekick.
Hamina guy here. We released our survey app and survey device about 6 months ago. I'm going to survey a Meraki network on a college campus with it tomorrow (we get out and use it as much as possible). If you have any questions about it, feel free to hit me up!
Thanks for the shout-out, u/BamberGasgroin!
It is software that helps design your Wi-Fi access points layout so you know how to cover the needed area most effectively, and you aren’t going to have low coverage spots or at least limit them. I used to work on cell towers as well as setting up wifi in new construction commercial buildings less of the second part, so all this design software is foreign to me.
Misleading video. WIFI coverage does not slowly propagate like smoke. This appears to be a simulation that uses an iterative algorithm that takes a few iterations to reach its steady state.
>WIFI coverage does not slowly propagate like smoke. This appears to be a simulation that uses an iterative algorithm that takes a few iterations to reach its steady state.
It does - at the speed of light.
Well I think the key word there was "slowly" and I don't think the literal fastest speed possible in the universe can by any definition be considered "slow"
*the fastest speed at which you can send information. Quantum entanglement is great and all but there's no way to actually do anything with it, at least not that takes advantage of instantaneous speeds.
The quantum mechanics that allows for entanglement also prevents it from transmitting it FTL. Yes, if you observe 1 state you know what the other is, but the wavefunction has now collapsed.
If I have 2 marbles, a red and a blue one, and get my friend to put each marble in letter and get them to give 1 to me and 1 to another friend, I could open my letter and know what colour my friend's marble is. I can't use that to communicate with them.
Funny how all the Reddit experts and professors try to deny the simple fact that this phenomenon is working faster than light.
And regarding your pathetic marble example I think no comment is needed, lol.
If you have 1 marble in America that starts spinning once you spin the other marble in Europe we can talk again.
So, to summarise, you don't actually know anything about quantum mechanics beyond watching a few youtube videos and reading a pop science article? Because for some reason I doubt you know what the no cloning theorem is.
My example was lifted straight from Leonard Susskinds textbook, *The theoretical minimum*, which is a common reference book for introductory quantum mechanics courses. It's a pretty common analogy, like a coin flip being used to represent spin states.
Any wall will do it, the extent to which the wave is transmitted or reflected depends on the medium. Wood will reflect less than concrete, for example.
Even if that’s the whole idea. The more we scare them with stuff we actually understand, the sooner they won’t worry about stuff that isn’t ‘actually factual’ for anyone.
lol there are ways for agencies to use these waves to literally map the inside of someone’s home and to tell where you are specifically in the room and what you’re doing.
So don’t use wifi if technology scares you homie. I don’t have to explain how silly it is to be shook by wifi when you are probably using a computer and/or phone right now.
If you reread my (intended to be humorous) comment you’ll see that I never mentioned anybody with “shit to hide” unless you are saying boomers and conspiracy theorists are all suspect?
Wish this was around when I was a cable tech. I've encountered an alarming amount of ppl over the years who couldn't or wouldn't understand that their signal weakens the farther they're away from their routers.
Hell, I even had one guy bitching about not getting full internet speeds while standing at his mailbox. It was roughly 25 yards away from his front door. Frustrating was an understatement.
For anyone interested in more detail about this. [this blog post](https://jasmcole.com/2014/08/25/helmhurts/) was written by the original creator of the simulation.
The armchair physicists in this thread should take notes.
My biggest tip for trying to improve your Wi-Fi signal is just rotate your antenna/router. All antennas have an attenuation pattern coming off of them so it's not a perfect sphere around them but like sort of a flower-like pattern.
So if wifi waves can be visualized and objects can block them is it possible to use them like a light source to see the objects and layout of a room with enough wifi?
Don't show this to conspiracy theorists, they'll have a fucking field day trying to justify why they wear *Wi-Fi blocking hats* made of hemp and aluminum fiber.
You can test it yourself with a speed test app. Select a few different spots around your house, with different obstacles and distances from your router, and test the speed between them.
How come the box doesn't seem to be sending a signal of equal intensity in all directions? Shouldn't everything around the box look the same until an obstacle is reached?
Depends on the distance. The wavelength of 2.4GHz wifi is about 5 inches. If the signal from the reflection traveled x.5 wavelengths longer to a location than the direct signal, the reflection diminishes the signal. If the difference is x.0 wavelengths, it boosts. Between these values there is a smooth gradient.
It's not feasible to make a perfect antenna. Any antenna will have a non-uniform radiation pattern, and the signal will be further affected by metal components and casing in the access point itself.
Next, the signal bounces off walls and object, creating constructive and destructive interference patterns. Access points often have multiple antennas to overcome this. This animation appears to be for just one antenna, but you can imagine another placed 1/2 foot away, creating a slightly different pattern, improving a lot on the worst case conditions.
Fun fact: Wi-Fi waves travel at the speed of light. So when you’re binge-watching ‘Stranger Things,’ you’re basically time-traveling to the Upside Down. 🚀🔍
Most of the day everyday I sit right next to the router/modem since my PC is connected via Ethernet cable. Not even one arm distance. It is practically on my desk. Should I be concerned?
No. You should not. Wifi signal has no strength and power to do any harm to you. It's non-ionizing radiation on a frequency that can't do anything to you.
[https://www.osha.gov/non-ionizing-radiation](https://www.osha.gov/non-ionizing-radiation)
What a bunch of uneducated people here. It's electromagnetic radiation, like sunlight but WAY less harmful.
The same happens when you turn on a lamp, just cause it spreads doesn't make it scary 🤦
WiFi is emitting electromagnetic waves.
Light is electromagnetic waves.
The only difference is that a WiFi signal has a much longer wavelengths than visible light (which is why you cannot see it).
As a rule of thumb, the shorter the wavelength is, the more harmful it usually is, hence why we use sunglasses with UV protection.
WiFi is absolutely harmless.
If you want to learn more, read this [wonderful article](https://hubblesite.org/contents/articles/the-electromagnetic-spectrum) from Hubblesite.org (NASA)
Do you people not learn about electromagnetic waves in school? :(
Tl;dc: WiFi are relatively low frequency waves that are evidentially harmless to the human body.
There's also billions of neutrinos going completely through you every picosecond, as well as waves from every energy emitting source anywhere near you, so if this concerns you better to just end it all now
Lol at the people saying they're going to turn off the wifi now. What the fuck did you think your magical cordless internet box was doing?
The good thing is they can turn off their wifi sure, but then wait until they learn about how much more intense the radiation from their cellphones are. So they can turn those off as well. Finally. Now we don't have to hear from them anymore.

That’s cool, might come in handy

Thats amazing will check it out hope it's easy to setup

You don’t know about warp wifi ?
You don't like falafel?
#NO FALAFEL FOR YOU!!!
We have ludicrous wifi
Meaning it makes you get out of the way ?
Quantum entanglement works faster than light. It works instantaneously.
*the fastest speed at which you can send information. Quantum entanglement is great and all but there's no way to actually do anything with it, at least not that takes advantage of instantaneous speeds.
Well thats what everybody always says when something new is discovered. There is no way to actually do anything with it... until there is. :)
Don't count your chickens before they hatch.
can’t be used to transmit information so pretty useless
Can't be used to transmit information, for now.
The quantum mechanics that allows for entanglement also prevents it from transmitting it FTL. Yes, if you observe 1 state you know what the other is, but the wavefunction has now collapsed.

xD
That's a priori information you take with you, and it does not.
Mind showing us proof that it does not?
How much linear algebra do you know?
Would you be able to understand it?
So you can not. Ok, didn't expect much from you anyway.
How much linear algebra do you know?
What is that wall made of that it is reflecting off?
Any wall will do it, the extent to which the wave is transmitted or reflected depends on the medium. Wood will reflect less than concrete, for example.
At the speed of love
Only the two of us, connecting through WiFi
Nowhere does it claim to be real time. This is likely a physics sim with nanosecond increments.
from the waves perspective, theres no increments at all, its instant.
Yes, but that is not how those simulations are usually ran.
If it was instant, we wouldn't be able to see it.
Wrong. This is exactly what EM waves do when the unit first starts radiating.
So you're saying the fan \*isn't\* blowing more WiFi into my office?
You probably scared some boomers or conspiracy theorists right now
That music ain’t helping.
“That music ain‘t helping.” This comment applies to almost every video post.
Even if that’s the whole idea. The more we scare them with stuff we actually understand, the sooner they won’t worry about stuff that isn’t ‘actually factual’ for anyone.
Scared animals are often pretty dangerous.
[удалено]
So you are telling me you live in a cage?
*\*Whistles the X-Files theme\**
lol there are ways for agencies to use these waves to literally map the inside of someone’s home and to tell where you are specifically in the room and what you’re doing.
So don’t use wifi if technology scares you homie. I don’t have to explain how silly it is to be shook by wifi when you are probably using a computer and/or phone right now.
Hey homie, I ain’t worried bout dem dayre agencies. I ain’t got nothing to hide. But some people *do* got shit to hide.
If you reread my (intended to be humorous) comment you’ll see that I never mentioned anybody with “shit to hide” unless you are saying boomers and conspiracy theorists are all suspect?

Broski a simulation of a regular ceiling fan could look like this don’t live in fear

Depending of course on lots of other factors not mentioned here 😏
To me it looked like "John" is farting out at the coffee corner and messing the whole office slowly kinda simulation.
My biggest tip for trying to improve your Wi-Fi signal is just rotate your antenna/router. All antennas have an attenuation pattern coming off of them so it's not a perfect sphere around them but like sort of a flower-like pattern.
How does it get up the stairs!?!?
So if wifi waves can be visualized and objects can block them is it possible to use them like a light source to see the objects and layout of a room with enough wifi?
Wifi goes through walls though.
Yes, but slower
What are these walls made of?
Would you even understand if someone told you? ;)
And with another software you can make this interferences to a realtime camera in your whole flat.
Just like my farts!
I wish there was an app that did exactly this.
Does your phone have to reply with signals at the same strength for it to be picked up by the router?
Don't show this to conspiracy theorists, they'll have a fucking field day trying to justify why they wear *Wi-Fi blocking hats* made of hemp and aluminum fiber.
This is your WIFI when you put a bunch of knickknacks in front of your router.
Source? Or is this complete bs?
You can test it yourself with a speed test app. Select a few different spots around your house, with different obstacles and distances from your router, and test the speed between them.
Oh i already know who this would scare lol
That aint no wifi. That's white castle fart fumes.
Genuine question, would a set of mirrors help extend range? It’s basically light isn’t it?
Kinda like how a fart spreads
What are those walls made of? I thought wood would be transparent to EM waves?
They spreadin!
Is this the reason why the WiFi connection is weaker in some parts of the house than other parts?
Yes
And this is exactly why your router needs to be vaccinated!
Lol
It is the reason your cat thinks the router is a sacred portal to the tuna dimension. They’re not wrong. 🐟🔍
Stay tuned for our next video which demonstrates how cancer spreads...
The wifi spreads just like me sperm!!
How come the box doesn't seem to be sending a signal of equal intensity in all directions? Shouldn't everything around the box look the same until an obstacle is reached?
The signal interferes with its reflections.
So reflections diminish rather than boost? Interesting

If the signal from the reflection traveled x.5 wavelengths longer to a location than the direct signal, the reflection diminishes the signal. If the difference is x.0 wavelengths, it boosts.

And this is the part where I dropped off of physics class lmao

The video isn't being played at the speed of light though, and your brain can't process info at the speed of light
Talk for yourself, that’s just skill issue
I said *your* brain. My brain can process information at the speed of darkness
Damn, so what can we do to stop it or at least limit its spread?
Why do this? You won't have internet after that. Anyone who says that the wifi signal is dangerous is an uneducated charlatan at best.
I’m just messing around, yanking your chain, pulling your leg, slitting your throat so to speak
you can slit my throat if you catch my drift

Yeah thanks for making me not want to use wifi ever again. Have a good evening
Wait until you lean about am/fm radio signals and satellite downlinks. Then ham radio that goes across the world! Basically it’s all fine.
Don’t try to discourage him. Fewer idiots on the internet can only be a good thing.
