One advantage you have in transmitting electromagnetic waves in a vacuum is that the speed of light c is a constant for all frequencies. That is not true in a material because the phase velocity in a dielectric material will differ with frequency. To send information you need a band of frequencies around the carrier and so in a material (i.e. circuit board) the different phase velocities of the different frequency components will cause dispersion and signal integrity issues.
@@shanent5793 ... You understand what Speed of Light is and why we can't send data faster than that, right? And that it doesn't depend on the atmosphere or diameter of a planet...
Someday hopefully if we have a human colony on mars, we could set up and internet cache system, data centre on earth sends (whatever data) to mars to be stored and accessed locally, depending on the population and interests, AI predictive models could pre spool up data. We cant change the speed of light, but we could be sending data packets in the mulit terabit or even petabyte range in the next few decades. having a data transmission that big could almost negate the latency time.

This explains why we do not receive radio transmissions of other civilizations in space. They also made swift transition to lasers and directional aspect of lasers makes it almost impossible to receive by a chance.
Not really. Even at lightspeed the Radius we can listen to or send is sooooooo small. Imagine our galaxy is the earth and now you are on a beach and the area we cover is smaller then a grain of sand. There would be no way that someone is that close. So someone would needed to send a signal thousand years or even longer ago so we hear or see a signal today. And ttthats only our Galaxy. Now imagine billions of billions of other earths in space. Even if there would be someone he needed to be in our Galaxy and that really close (in space meaussures)
@@Blackbirdone11 I know all of that 4D puzzle of space and time. But moving to lasers it makes receiving signal exponentially less probable. So going back to Fermi’s question, everyone is where and when they are supposed to be, but we will just never receive anything.
How I imagine the Mars colony internet would work would be that the most popular content on Earth would be curated by an AI every day, then sent to Mars to be stored locally for the entertainment of the people living there. That way, you could still scroll on your phone during your break or downtime without having to wait for the system to ping Earth for it. If you do want anything else, you can still request it, but you'll have to put up with the delay. The system would also work the other way round.
the future of space internet is going to be a massive data server that sits in space that then communicates long distance over starlink-esque systems to other servers so you can do massive data dumps as it makes its way to the next server imo, since having a direct call every time for a specific piece of data is dumb you need to have mass storage instead basically cloning everything on earths internet and then dumping it again on server on mars and vis-versa allowing for what will look like near instant communication when in fact you will still be between 3-30 minutes of delay in actual data. additionally you will need to develop some sort of mini nuclear reactor to deal with the power issue. aside from this you will also need to develop some sort of live communications network between earth and mars that fixes the delay not sure what this will look like probably something with quantum computing and physics cause it probably isnt possible other wise.
IR can go through clouds, if I'm not mistaken. Also dust. That makes it a very compelling candidate for the task. It makes me hopeful that scientists will find more and more ways to make this faster. My big concerns are any potential for atmospheric or gravitational lensing, but I know these issues could easily be conquered.
It’s impressive to think we can communicate with Mars in my opinion. I get terrible cell reception and Radio stations all the time so space Agencies must be incredibly patient.
You can increase transfer speeds by also using a meshed network. If you had a base on Mars, you could split the packet into 3 (for instance), send it to a satellite each then to the base where it gets reconstructed.
If the center frequency is lower than half the bandwidth it will cause aliasing and degrade the signal. In practice it's easier to work with a signal where the bandwidth is only a small fraction of the frequency, so you can have a better signal to noise ratio and higher throughput for the same bandwidth at higher frequencies. Complex encodings needed at low frequencies also have higher latency which will increase the bandwidth-delay product, limiting throughput for protocols like TCP
@@shanent5793 Yes, that's for example the reason why shortwave radio was only used for voice communication, and not music: because listening to music in Shortwave sucks... that's like listening to an MP3 in 32 kbs. AM is the minimum of frequency you need for listenable sound quality. That's also the reason why when they started HD TV, they scrapped the lower FM TV frequencies in favor of higher bands: because lowband TV channels wouldn't be able to carry HD signals.
Using this network, the ping would be approximately 0.00333564604 milliseconds per kilometer. So ping to earth, when you would be on Mars (if the distance would be 225,000,000 kilometers), would amount to 750,000 milliseconds (750 seconds, so 12.5 minutes).
I'll be 63 in a couple months and spent today under my travel trailer fixing water damage, which I will continue to do until it is all fixed. Laying in gravel is more fun than our stunning 2.02 Mbps download speed today.
The frequency does not limit the amount of data that can be sent over RF. The modulation and channel width are the factors there. A 20Mhz wide channel with 1024 QAM is the same regardless of frequency. The frequency changes the propagation characteristics of the wave, low frequency passes through matter better than high frequency up to a point, eventually the higher frequency can pass between atoms, but that's a whole different thing...
A 20MHz wide channel will alias itself at frequencies below 10MHz making the signal unusable, so there is some dependence on frequency. Lower frequencies passing through matter also limits the signal to noise ratio, effectively reducing the throughput.
@@garystinten9339 yes, the beam divergence is limited by diffraction, so for a given aperture size a higher frequency will have lower divergence, which will also improve SNR

How to test the speed of quantum comms.. Send a quantum command to a craft near Mars and get the response back by Radio . If the response comes back in half the expected time, then the quantum speed would be faster than light.
Australian radio telescopes are not within bowl-shaped mountainous regions... rather tehy are just in the middle of a large area where there are restrictions on what radio communication is allowed. basically: the government just designates an area several hundred kilometres wide and says "nope" to people using certain tech.
You expect this kind of relative question in a such condensed subject as fucking LASER telecomunications for satelites light years away with asteroids and stuffs is rather dumb, you can make it out depending on distance which is probably what he said either between 1mbp/s to roughly gigabit speed if its closer like a satelite orbiting moon
Actually radio waves do not move atathe speed of light. They are slightly slower so over a short time the lasers would outstrip them for data transmission.
Approximately 0.00333564604 milliseconds per kilometer. So ping when you would be on Mars (if the distance would be 225,000,000 kilometers), would amount to 750,000 milliseconds (750 seconds, so 12.5 minutes).
Lasers having shorter wavelength boosting speeds is meaningless over extreme distance, as you will need to significantly slow your speed anyway. You can get oodles of gigabits with lasers through fiber, or shorter distances through air, but not through millions of miles of space. I would say the biggest benefit is a much more narrow beam, reducing signal loss.
Apollo 11 could transmit live TV audio and video without any issues. Even today, a reporter in China delays to respond to the anchor, but not the astronauts. Starting with the fact that Nixon could speak loud and clear (no delays by phone) with the astronauts, isn't it easier to use a modem?
