What frequencies are these using? Also what is the speed? I assume its low frequency and pretty slow.

Being in Europe, I would assume 868 Mhz. And the data rate depends on SF (spreading factor) used. https://docs.exploratory.engineering/lora/dr_sf/

LoRa can be as low a 4 bytes per second IIRC. Yes, bytes per second. I’m not sure where it tops out. 10’s of byres per second maybe?

It took a surprising amount of clicks to find this but the baud rate can be up to 50kbps. See "data rates":

250 bits/s with a maximum payload of 59 bits is the lowest limit on LoRa.

Wow! Way faster than I remembered! It was a while back. I spent some time trying to design a payload for a slow application with connectivity challenges once upon a time.
