This week Semtech is announcing 2.4 Ghz LoRa. They will be coming with more public new soon. But it looks very interesting.
What are your thoughts about this? And how would this fit best in The Things Network?
And the datasheet is here:
I guess the most interesting part is
BLE PHY layer compatibility
Other than that, I'd be interested in more information about data rates/limitations, and some performance comparison with pure BLE when it comes to range & bandwidth
Does this collide with typical WiFi stuff going on on 2.4GHz? One of the good things of LoRaWAN was/is that it not uses the totally overcrowded 2.4GHz frequency, we have already enough things trying to grab airtime on 2.4GHz.
that's the technical part, but we also used that argument to emphasize why LoRaWAN was that cool and useful. We may need to think about a good way to explain this keeping in mind what we said so far.
edit: i didn't had time to google in detail, but does this allow OTA firmware updates?
Since you asked my thoughts on this are that TTN should continue their plans of supporting routing Bluetooth LE - remember Bluetooth 5 is already reaching 2Km+ as is also very low power, even lower than LoRa. That's a technology that's already out there on more than a billion devices and NOT locked to a single chip provider.
Quite surprised it is not actual vaporware but product with complete specifications and detailed documentation.I'm curious about range with LoRa modulation although not expecting longer range than in sub GHz band. Due to higher frequency there could be potentialy shorter time on air resulting in even lower power consumption - something that BLE made so LE.Question is if sx1280 will be accompanied with concetrator chipset of some kind (possibly multi-band)...

That's FSK, for LoRa 2.4Ghz it's
