I was thinking at the same corner.
Do we need polarization diversity?
The short answer is no. No one is using it!
What longer answer is – LoRa chirp modulation mitigates this issue.
IMHO – does not solve it only mitigate it.
I was thinking to connect two Lora antennas at 90 degree with two receivers and just move around with one Lora transmitting node – I’m pretty sure that somebody else did such test, Isn’t it?
Do we have such data?
Thanks in advance
