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?

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.

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.

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

What was Wenger thinking sending Walcott on that early?

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