Add tables for data for each country/region Frequencies, SpreadingFactors, and CodingRates

[chansizzle]

Could you add tables to supply the data for Frequencies, SpreadingFactors, and CodingRates for each region and/or country to each applicable wiki and webpage? Otherwise, how will the correct values for Frequencies, SpreadingFactors, and CodingRates be correctly selected?

I found this, which I believe helps get much of the required information: https://www.rfwireless-world.com/Terminology/LoRaWAN-Spreading-factor-Range-and-Data-Rate.html

Trying to setup T-deck plus for USA I do not know what to select.

This from that URL does not help me:

US (for a few American countries) which is 915MHz? (SpreadingFactor=? , CodingRate=?) still to be validated.

When connecting to the WiFiAP called 'LoRaTracker-AP' to configure the device, the LoRa section is prepopulated with 433MHz settings. The questions that will need to be answered for every device configured.

As far as I know there is not a defined value for US, this is why its so in the wiki.

prepopulated value for first configuration is like so, just a value to be validated or changed. If you are from US , could you help me validate it with your local Ham Groups to have this right?

I am in the USA. I can make some inquiries. I do know that the USA frequency / band plan is 902 - 928 MHz

It doesn't make much sense to do a table per country/region since (to the best of my knowledge) the LoRa APRS settings are identical for the entire world, with exception fo 3 countries: Poland, UK and US. Unfortunately, as discussed above, we have the least information about US. Getting more info about LoRa APRS in USA would be indeed helpful.

The linked LoraWAN parameters don't really help here, it is up to whoever designed/implemented/started using LoRa modulation for APRS in the USA to decide what frequencies and parameters to use, LoRa APRS is not LoraWAN. The HAM radio community in USA would be the best starting point of inquiry.

Some quick googling comes with a surprising result, looks like there are people in US that run LoRa APRS on 433.775 using the European settings (BW 125khz CR 4:5 SF 12) while others are using 915MHz ISM requencies. While there isn't an ISM band on 70cm in Region 2, if you are a licensed HAM you can use the 70cm HAM spectrum for LoRa activities (I am not a lawyer).

Some random checks on LoRa APRS gates in USA on aprs.fi seems to confirm the above, according to the comments in their description.
