My thoughts are that the LoRa 923-925 (“AS2”) frequency band available in Thailand is my best bet to legally (approved frequencies bands) penetrate 30 floors of a condo, from basement to the top, but maybe there is a better way?
Bad news. Looks like the Thai government has decreed the "long range (LoRA) band" (in modern, developed countries) to be the RFID short range band in Thailand; it's all very confusing here; but it appears the authorities have made the unlicensed max power so low that this band used in other countries for long range (LoRa) IoT is being pushed down to low range RFID status in Thailand. They appear to be licensing the spectrum to their established commercial telecom companies for any power of use to build a LoRaWAN.
So, it seems my plan to build my open personal LoRa WAN in Thailand
may have hit a local regulatory brick wall
Update: I have sent emails to the government standards and licensing groups to see if I can transmit at 500mW or less (seems that 500mW may be the ceiling for unlicensed applications, which should be OK for my applications).
