that about 1/1000 of your phones RF power output, and the distance is 384400km

  The magic of a clear line of sight and vacuum for a good ~384’300km!

  So should we do low power communications by using the moon as reflector dish?

    Also, directional vs omnidirectional antennas.

      This is the most important part.

    There was a NSA program that listened to soviet messages by collecting the transmissions that bounced off the moon.

      I gotta say, the moons really starting to sound like a fucking snitch.

    Two thirds of a million kilometres under good conditions and at a precise angle to get a picture of goatse moontooth’d to my phone

    I am worried about 2sec ping

  That’s almost the distance between my bed and the kitchen before my first cup of coffee!

  I bet the receiver that had noise figure low enough to detect that signal consumed more than 3nW while doing it.

  My Bluetooth buds often get interference - technically 100 mW, distance from my head to a pocket.

    technically 100 mW

    Technically a maximum of 100 mW, but realistically much lower than that.

  I use about 800mW for my fpv drone and if you get a little bit away from yourself and go behind a tree or something you could lose video pretty easily

    Wonder what the latency would be like trying to fly my 3.5" on the moon from earth

    Although I suppose the lack of atmosphere would be the bigger issue…

      Well duh is space, you gotta put flames on the side for it to go fast

      Think of the speeds you could fly at with no drag! I’m so bummed that the Grace Hopper drone didn’t get to fly after Intuitive Machines fluffed their second landing. That would have been awesome outreach from NASA.

      We want drones on the moon!

  To be fair, that’s an insignificant distance for light to travel.

  • 7eter@feddit.org ⁨3⁩ ⁨days⁩ ago

    Still takes at least 2 seconds for the round trip.

    • yesman@lemmy.world ⁨3⁩ ⁨days⁩ ago

      Well, according to my ex, even 30 or 90 seconds is an interval unworthy of consideration.
