Hello All,
I'd like to test the power of the community around the world and see if we can gather some feedback about those countries which allow only a portion of the FCC 915 MHz band to be used.
Full disclosure: I'm a LoRa Alliance committee member and there is already work going on in this area, but the Alliance is fuelled by its members, for both cash and brain power and it would be great to see the TTN community drive some real-world information back inwards.
The problem: The existing channel plan published in the LoRaWAN spec is for the full 902 - 928 MHz band and defines all the uplink channels to be below 915 MHz, and all the downlink channels to be above 915 MHz. Thats fine in those countries which have the full spectrum, but a headache for those countries which use a sub-band. I've summarised below. To work in those countries a new set of channel plans is needed.
So, what do you guys around the world know that can help? The frequencies below are just taken from Google, but what about your practical experience?? What are the blockers in the adjacent bands??? Are there other in-band systems causing congestion????
Thanks in advance!!
