Reconfigure EU channels for higher bands #13

Reconfigure the EU channels so that we can take advantage of 869.4mhz @ 500mW for PoC traffic

amirhaleem commented 3 years ago

I like this. Of course we'll need to do extensive testing. I forget which repo it was, but can you paste the note about how these changes have to land atomically across several repos?

the other changes are for router and miner - @Vagabond has a good point about the channel/frequency PoC validation likely breaking with the way it is implemented (as it expects the onion to be sent on any of the 8 channels), and we don't have a great way to expose the region to that part of the code. will require a little more thought.

This suggestion would force all LoRaWAN devices on the network to use a single channel. That would have a huge impact on the overall capacity.

If LoRaWAN devices do not use this single channel, PoC in EU would become very artificial, since it uses much more power than actual devices will.

Please don't do this: As @mfalkvidd mentions, it will give a unrealistic PoC indication while actual coverage will be much less (being limited by 25mW instead of 500mW).

Considering only on the matter of HNT rewards PoC witnesses.

Difference USA and Europe hotspots is 27dbm and 500mwatt and 14dbm 25mwatt. It requires a 6dbm in tx power to double the distance of radio waves. USA hotspots owners have been earning massive amounts of HNT because huge benefit of 500mwatt tx power. So they can easely have way more witnessers etc. Europe on the other hand is limited to 25mwatt PoC witness, so their range is way lower. Especially if stock antenna's and indoor placing of hotspots. So its less easy for european hotspots owners to gain same amounts of HNT rewards by PoC witness etc. Should the helium network offer people world wide the same level of difficulty to gain HNT rewards? USA has an unfair benefit and because this whole project for most is not only providing network coverage but has also financial rewarding aspects, shouldn't all people have the same financial benefits?

Also I agree on that if the sensors that use that network only use 14dbm than PoC on higher dbm's may kinda give artifial PoC coverage.

as I mentioned on Discord, this is not practically possible due to differing regional regulations. for example I do not believe there is any way to transmit @ 500mW (27dBm) in any of the AS923 regions.

generally tend to agree with @mfalkvidd and @timcooijmans on this change.
