I dont get it, How does latency affect bandwidth here?

Because we're not stationary, and nor is the moon. Latency means greater dispersion, and lower successful return rates.

  • Latency itself doesn't mean squat. Throw a pair of trancievers into deep space and no relative motion and all bitrate limiting factors (dispersion, multipath, doppler shift- I'm sure there's more) disappear besides SNR/inverse square and retransmission.

    Going beyond intuition- secondary reasoning says since GSO bandwidth & bitrate is acceptable for TV and sat phones by the hundred.

    Tercheriary is we have/had a few hundred bps from Voyager II and that's a might bit further out than the moon, and it was called out that using an 80meter dish it could be pushed to a little over 1kbps- which means at some point inverse square becomes the only non-neglegiable factor.

    So please, explain with something besides repeatedly saying "latency." Even if I'm wrong, they're strong enough counters to deserve more than a single word.

    • ... I'd love to see, this particular project, "throw a pair" of tranceivers into deep space.
