I feel like the more I read about #meshtastic and #LoRa, the more confused I get.

I'm pretty sure that:

• Meshtastic is an application built atop the #LoRaWAN protocol.
• LoRaWAN is a network protocol using LoRa.
• LoRa is a 900mhz spread-spectrum radio "mode" (as opposed to MFSK or AX25, etc).

I'm not 100% sure that's all correct, though. I've read bits about LoRa being used by Hams, too, which would suggest that it's not a spread-spectrum mode, or that it has alternate modes?
I'd like to experiment with data beyond just text messages, so maybe I just want a different LoRaWAN application, not Meshtastic specifically?
