Yes, but then it's slower for your computer to talk back to your Wi-Fi, so it ends up cancelling out
Push-Pull Config
Full duplex airflow signal enhancement
We can streamline this by making the room into 2 small tunnels from the router to the PC. This way there will be less obstacles in the room. But we need to add leafblowers on each side with a boost button.
What if we make the tubes really really small and wrap them in many protective layers to prevent other wind sources from messing with the signal.
RoRo stations. Roll on, roll off/out. The internet isn't a highway, it's a series of bullet trains in tube tunnels.
I wonder if anyone thinks OpenTTD would be more fun with a cyberspace theme? I know there's a neon grid grf (mod)...
Anyway, if this was a suitable solution for WiFi, we wouldn't need wired connections. That said, you can cut open a drink can to turn a WiFi router's signal into a focused beam using the aluminum, iirc.
Interestingly, this could be true and you could never find out experimentally iirc.
I watched a veritasium video about the 1 way speed of light vs 2 way that talked about it.
I watched the same video!
I was right about to disagree and type “wait this only applies to light” but then I remembered: radio is light.
Crazy to think about that!
It is nuts. It goes to show how far science goes proving things through deductions rather than direct observation. So much science is done that way.
I think that there would be some infinite energy glitches if it was actually true that light was faster 1 direction than another, so I think the assumption is a good one. But still fun facts
LOL! Yes, one has to consider this. ZOMG your's is the best comment!
^yes^ but ~pages~ will ^render^ kinda ~wavy~ i ^use^ a ~box~ fan ^myself^ for ~maximum~ speed
Yes, but the tailwind becomes a headwind on the way back to the router so you won't see any actual speed changes. Putting a fan on both ends will cancel each other out too.
You need to change all the gaseous air out for either liquid or a solid as waves propagate faster through them. You should start with filling your house with liquid oxygen as a nice half step so you still have something to breathe easily, as solids are a bit more tricky.
The general idea is correct, but since we're dealing with electronagnetic waves, they travel slower in any medium. So pumping out all the air of the room would technically make your wifi faster.
Liquid oxygen has (I think) a refractive index of about 1.2, so it would make the signals 20% slower (still very fast)
NERD
Dude waited 11 months of lurking and not posting or commenting anything, and breaks their silence with that attractive string of knowledge. I've got mad respect for them.
I'm a nerd too but come on, he's replying to an obvious joke with high school physics. There are more layers, do you want a more pedantic teardown?
Meh, we all have our personalities. A lot of people hate my personality, but I just figure it's best to assume everyone on the internet is a stranger that could be a potential friend. If they answer things blunt or love to extrapolate with excruciating detail... Who am I to judge. I just make jokes and hope they don't accidentally make someone feel bad. Like I really wanted to reply to yours saying that you were just trying to show off and get me to call your words attractive as well ; ) haha.
Yes, but only in one direction and if you use UDP instead of TCP. Also your MTU needs to be small enough for the packages to fit between the blades of the fan, otherwise that causes package fragmentation.
/s
No, the fan will blow the packets all over the place, which is fine for UDP, but any TCP/IP connection will suffer. Place the fan in front of the router so that the blades will catch any dropped packets and throw them back into the datastream.
uh, hi. If you place the blades in front of the router, it will start chopping the packets before they even reach. You need to use an bladeless fan
Just gotta adjust the MTU and fan RPM
that sweet spot
Alright so I've now got a router using cell signal hardwired into a Roomba randomly roaming the halls so everyone gets shitty connections all the time.
There are some stupid questions.
Tbf, it’s not like physics stuff is always obvious, especially when dealing with relativity or quantum mechanics. It just feels obvious if you’ve already learned about the research that’s already been done.
It isn’t even remotely intuitive that light should have a max speed that can’t be added to by moving its source relative to other things. Plus, light does interact with matter, but it can only be slowed down by it.
So less a stupid question and more just one that isn’t educated about something.
Yeah yeah, I know. I was mostly just kidding. Everything is magic if you’re ignorant and we shouldn’t shit on people for not knowing something and props to them for asking and seeking knowledge and all that.
But it’s really sad that very basic science like radio waves which are introduced in 5th or 6th grade could be so completely misunderstood.
I remember my 6th grade science class having a lively 15 minute discussion about whether or not rockets can work in space since there’s no air…. We’re looking at videos of rockets working in space and then debating whether or not they do. 🙄
On the contrary, given the premise its a smart observation from an unknownledged person.
“Wifi is waves in the air” is very very wrong but as it appears it’s what this person was thought to believe. Given that they trust this information the conclusion makes perfect sense.
The only “dumb” here is whoever explain wifi like this to them.
So what the post really amounts to is. “I applied actual reasoning to the information i was provided as fact and my conclusion seemed strange, so i will ask on no stupid questions to figure out whats really going on”
More intelligent than the majority of internet users.
"I don't know, can anyone help me learn?" gets so much respect from me. Incredibly powerful mindset.
This is not stupid at all. If Wi-Fi used matter instead of magnetic fields to propagate (like sound waves), a fan would affect it. Understanding magnetic fields is anything but intuitive.
Yeah, but it evens out since now your messages going back to the router have to swim upstream.
Could this be remedied by sending packets on a second antenna, with a fan blowing in the opposite direction?
Only if the two air streams don’t intersect, otherwise you’ll create a dead zone. Modern signal jammers are actually highly sophisticated fans.
Not inherently stupid question; they just don't know that radio waves don't travel through air but through space.
Sort of a serious answer because I'm bored: You're thinking of speeding up the air when what you should be thinking about is speeding up the waves. But then your waves are reaching you plenty fast already with latency being in the single digit ms range. Not much of a point in trying to accelerate that, really. You won't notice anyway.
If you feel like your internet connection via Wi-Fi is slow then the bottleneck is probably not with the Wi-Fi part of your network but the Internet Access Point behind it. Or even further down the line.
Now this is based on the assumption that you are in a fairly typical network environment, i.e. using semi-current hardware with moderate, if any, electromagnetic interference in the area. If you're living right next to a high voltage transformer station and using a router from 2008 then, yes, you're going to have Wi-Fi performance issues.
But in most cases, people complaining about "slow Wi-Fi" are actually suffering from Internet connectivity issues.
Think of it this way: If you enjoy your McDonald's from the local franchise but you can only get 100 burgers per hour from them (of course you need MOAR!) then upgrading your 320hp Camaro to a 400hp Mustang is not going to enable you to pick up appreciably more burgers from the drive through in the same amount of time.
Not entirely true.
In an apartment in the middle of a city, noisy neighbours can be a problem.
In those cases, it's best to jump to 5 GHz, and leave the 2.4 band alone.
The Wifi isn't waves made of air, the wifi is waves of the electromagnetic spectrum, similar to visible light, and they travel faster than you can perceive.
So no.
But you can do something similar with a microwave oven. It's just that any signal making it through the radiation of the oven would be disfigured and useless.
It's not 1 way traffic. Signals go both ways. To increase your wifi speeds, have 1 fan blow from your router to your device and 1 fan from your device blow towards your router. Signals go faster in warm air so make sure to pump up the thermostat. It also goes faster with less CO2 in the air so make sure to open all windows (unless you own a Mac). Lower moisture in the air also improves speeds, so crank your AC on max. Also placing both your router and device in rice helps.
No but if you fill the room with water then it should be way faster
Depends on the direction the fan is facing. If it's blowing towards you, that increases air pressure in front of it, which means more things for photons to interact with and a lower speed of light, thus slower wifi. Away from you would decrease the pressure and result in faster wifi due to the increased speed of light. Theoretically at least. I don't think this effect is measurable.
Edit: thinking about it, the electromagnetic noise from a fan motor would likely be worse than the benefit. You might even be able to detect that
If you can create a vacuum with said fan, it can be faster.
Yes but you have to put a slit in front of it so the wifi waves turn into wifi particles.
If you had a fan blowing out the window, it could slightly reduce the density of the air in your house, leading to a tiny increase in the speed of light through it, so that would make the waves technically faster, but by a vanishingly small margin
It wouldn't increase the bitrate of your router at all, so it wouldn't make a difference, but the waves would be faster
I like this question tbh
