LoRa can work with many frequency bands in the ISM band of frequencies, but the popular bands are
This is because the only known semiconductor product capable of completing a LoRaWAN, the Semtech SX1301 supports only these bands. This might remain so for some time to come because of Semtech keeping things tight with the supply of SX1301 and even documentation about the SX1301.
Now the confusion arises in India because the 865 MHz to 867 MHz license free band in India ends at 867 MHz, as per the Ministry of Communications and Information Technology directions as mentioned here. Bit of a conundrum because in the ITU Region 1 (Mostly Europe) 863-870 MHz is license free (How I wish the British had decided our frequency bands before leaving).
