Moonbounce isn't practical for any real application nowadays. It's a fun experiment and a PR stunt.
Why isn't it practical? Background noise makes it unreliable?

A consumer protocol, but also way over consumer power level (350W). No wonder it's the furthest LoRa message sent. Let's bump it up to 1kW and break the record again...

Amateur radio operators still do it, and with purpose-made codecs and really slow speeds it's not that out of reach (i.e. at least for those you don't need a radio telescope dish), but that's just because it's an interesting challenge.

Just a guess: given that LoRa operates on line of sight, when trying to update a gateways with sensor status (e.g. GPS position of tracked item) the operator won't be able to get realtime reports if the gateway isn't positioned at a high enough altitude relative to the sensor. You can mitigate this by having many gateway/collectors at high points on buildings/hills, but bouncing signals off the moon seems like an int…
This is a cool stunt, but it's not at all practical for IoT communications. For one thing, it requires a big dish and a huge amount of transmission power to get a barely-distinguishable reflected signal. The other big issue is that it doesn't scale, because there's no directionality: the reflected signal will be scattered off the moon and received everywhere on the hemisphere of earth where the moon is above the hori…

#18When it says amplified to 350W, how's that work out of interest, is that done actively with a 'power amplifier' or..?
