I actually just bought my first meshtastic node and of course it uses LoRa and so I’m now diving into the encoding rates and shit like that. The very long slow seems to use 62 kHz of bandwidth and offers a transverse beat of 0.09kbps. However, you get a link budget of -157dB of decoding on that, which is insane.

Did you see that ludicrous display last night?

I’m in the process of building my first LoRa with an old ESP I had lying around. Excited to see where this tech goes

Are you actually fully building your own, or are you going to flash, meshtastic? Because apparently, it’s extremely finicky about communication. And if you get one setting different on the modem settings, it won’t talk to anything else except the ones you set up yourself.
900MHz WiFi, 20-40Mbps at “10 miles” (what’s that, 16km?). I mean I love the vastly simpler authentication part of the protocol but isn’t it just a mobile cell band at that point?
Yes and no, it’s true it can get similar distance and somewhat similar data speeds as a cell tower
But, at 900MHz you don’t need a license to run it so you can do cool things, like a community WiFi mesh kinda like meshtastic, but with real speeds where hosting mesh-only websites and services become realistic
You can run 5g on unlicensed spectrum too, and there are fully open source 5g stacks. The primary issue there is that most phones don’t have the hardware to connect to those networks. But the same is true right now of wifi on 900 MHz.

Right, but ah to ah mesh, then ac WAPs at opportune locations. This will allow communities to connect to one another, and have local access to current devices. This ah looks pretty amazing tbh

What was Wenger thinking sending Walcott on that early?

The problem with Arsenal is that they always try and walk it in…

No, no can do. I’m seeing a bird.

“That final output is 69.420Mhz” it was destiny.
