 - [✓] **~915 MHz**, untested, operation inside the amateur radio band plan in IARU2 region (US)
 - [✓] **~2400 MHz**, untested, inside the amateur band plan, also possible to run using ISM band plan, E28-2G4M27S modules, https://www.manualslib.com/manual/1591128/Ebyte-E28-2g4m27s.html

 LoRa modules support various SF (spreading factors) and various bandwidths, table below summarizes possible options, with the maximum reasonable speed and signal level:
 - 433 MHz: ranging from 292 bps (SF9, -138 dbm) up to 1560 bps (SF6, -128 dBm) for legal 433 MHz 20kHz channel
 - 868/915MHz: ranging from 293 bps (SF12, -137 dbm) up to 9375 bps (SF6, -118 dBm) for legal 868 Mhz 125kHz channel
