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.

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.

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.

@glenwaldrop8166 Ай бұрын

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...

@shanent5793 Ай бұрын

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.

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
