LoRa modems are all black boxes, available only from a single company. Meanwhile, IEEE 802.11ah, a.k.a. Wi-Fi HaLow, is an open standard that you can download without a fee: https://ieeexplore.ieee.org/document/9363693
That is all.
Edit: fixed terminology
Looks like we’re using different terminology. I mean the bits that take care of the RF part. The “chirp spread spectrum”. Perhaps “modem” would be a better word.
But regardless, whatever word you use to refer to it, it’s proprietary. And that’s bad.
Yeah, I agree. That is not great.
