That's what the anti-tachyon modulation circuit is for, to change the time phase and remove most of that lag. Once they're in sync, it's literally real time!
It’s easy, you just need a big antenna, low noise receiver (just cool it) for low bandwidth (keeps noise power low) and no interferers in the same frequency band.

Omnidirectional antennas attempt to radiate equally horizontally. An isotropic antenna radiates equally in all directions but is only theoretical. All antennas have some gain.
That being said, there are some antennas that attempt to minimize that gain and be as non-directional as possible while other antennas attempt to maximize that gain and become as directional as possible.

Perfect. Now put those on cell phones and make it fit in your pocket.
That’s fair, though I think we also should thank the use of Travelling Wave Tubes (TWTs or ‘twits’). These little tubes of witchcraft amplify the transmission signal to make sure we can still hear, say, the Voyager 1 that’s currently over 15-billion miles away.
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.

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?
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
Welcome to 2025!
Also, directional vs omnidirectional antennas.
This is the most important part.
And not encoding any data. Well a laser pulse is kind of datum.
One bit! That’s all you get!
I am worried about 2000ms ping

There was a NSA program that listened to soviet messages by collecting the transmissions that bounced off the moon.
I gotta say, the moon’s really starting to sound like a fucking snitch.
My Bluetooth buds often get interference - technically 100 mW, distance from my head to a pocket.
Technically a maximum of 100 mW, but realistically much lower than that.

Shrimple as that
It’s almost too easy
*directional antenna
Show me a non-directional antenna.
enterprisecontrol.co.uk/…/non-directional-antenna…
Just because you call it non-directional doesn’t mean it is. They all have gain compared to a theoretical isotropic antenna.
And how is that relevant? Everybody knows they mean low gain antennas
Omni-directional antennas?
Omnidirectional antennas attempt to radiate equally horizontally. An isotropic antenna radiates equally in all directions but is only theoretical. All antennas have some gain.
That being said, there are some antennas that attempt to minimize that gain and be as non-directional as possible while other antennas attempt to maximize that gain and become as directional as possible.

Technology always gets better with no regard to physical limits.
(People who argue this unironically are a pet peeve of mine. Yes, there are limitations on what’s possible.)

To be fair, that’s an insignificant distance for light to travel.
Still takes at least 2 seconds for the round trip.
Well, according to my ex, even 30 or 90 seconds is an interval unworthy of consideration.

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

We want drones on the moon!
Well duh is space, you gotta put flames on the side for it to go fast
I bet the receiver that had noise figure low enough to detect that signal consumed more than 3nW while doing it.
