Meshtastic - An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices

https://youtu.be/EAQI2ZSmxPU

Long range (LoRa) mesh networks are interesting alternatives to communication, especially when state actors are blocking internet access for various reasons.

What up with everyone using the acronym LoRa. It is becoming confusing.

AnUnusualRelic@lemmy.world · 16 pts · 2y (1 reply)

We ran out of acronyms a long time ago.

In other words, a ROOAALTA.

When talking about LoRa, I always think about the wireless protocol/chip... Its been around for a long time (specially when capitalized like that) .... What other Lora are you talking about?

In generative AIs LoRAs are "Low-Rank Adaptions". Basically an overlay for existing networks to teach them new things.

It stands for Long Range, so would otherwise have been LR.

perhaps LoRa is the name of the singularity and it is all coming together

tell us then, beside your waifu name "lora", what/which else is named after your waifu, that confuses you?

Not sure why you decided to ask that person the question like that, but when it comes to AI, LoRA stands for Low-Rank Adaptation. They are used to fine-tune models. Next time be a bit more polite.

The documentation is a little lacking. What exactly is the range of each decide? I see the record of 100+ miles but can I easily connect people within a few miles?

What exactly does this do? Is it just a messaging app?

Dude this is a great response. I’ve spent the last hour trying to piece together how it works and you nailed everything perfectly.

I’m a ham so familiar with radios and have been trying to setup some Wi-Fi links between friends but this seems a little more practical.

Is a few mile range possible with houses etc in the way? We’re all about a mile away from each other, although I may throw an antenna on top of my house (maybe 10m up)

Funny. I have some Disc Lite 5s that I’ve yet to get going due to difficulty of setup. We did have plans of a little Wi-Fi mesh setup to setup a WAN.

This would just be for fun between a few friends and the price point is pretty attractive. Plus the ham in me is a little excited about messing with antennas.

I've done my little stupid tests. I have 2 Heltec LoRa 32 V3s both with the stock antenna. Inside the city I can get 500m on LongFast and 700m on VeryLongSlow. The other node was placed inside a building on the 1st floor.

But that's obviously a terrible test.

Not sure if they’ve improved it but meshtastic also used to require a module per device/phone so sadly you can’t dot them around and allow multiple people to share them like with group events.
