No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Do you mean through radio waves like APRS, 10m BBS, or HAMNET? Interent though peer to peer like Freenet (Hyphanet)? Or solely through Mesh like MeshBBS?
I think the issue with running through Mesh is bandwith and range. Look how "limited" APRS or 10m BBS is (I know FCC band requirements and what not)
Well, I don’t know what the details would look like. I was hoping the good people of lemmy could help me out with that
I guess how would be the source of transmission be? All of those I listed have sort of a mesh/peer to peer community. The difference is inoperability.
With 10m BBS i can get really far due to antenna and how large the radio wave is. On the flipside Meshtastic (which is 915 mhz US band and 400 in Euro I believe) has a tiny antenna, way less range,however you have less interference from other stations or space weather.
With conventional internet (cable, dial up, satilite) we have peer to peer, which is close to mesh networking (freenet, torrants, file sharing sites, Zeronet).
I'm only scratching the surface here.
Meshtastic seems to only support text messaging. Is that due to a limitation on the frequency it uses?
So in the US, mesh is on the ISM 902-928 mhz band and is unlicensed. It has both a power and bandwidth restriction (26mhz) compaired other mode to prevent harmful interference to other users.
We can look at CB Single Sideband (SSB) that you can split the audio into two different "sides" and have operators transmiting on upper and lower without interfering with another.
Tl;dr too nerdy: Techincally yes, you can use voice over mesh and a lot of amateur radio operators transmit voice over 900 into the giga bands sucessfully. All Meshtastic is, is a two way radio.
I believe the reason it's only text based is due to collision. Irrc last year's Ham Fest Mesh crashed due to too many users on the "network". It's been patched since then and everyone uses (mid short? I cant remember atm) a different mode now.
Ish. Frequency dictates bandwidth (this is a very basic statement), and meshtastic is low bandwidth. This means you can still send any amount of data you like, just like in the old days of the internet, but the more there is, the longer it takes. So meshtastic is fine for text, but would require an amazing amount of buffering to be able to send video.
