LoRaWAN
- Check LoRaWAN Regional Parameters Rev1.0.2
- India 865-867 MHz ISM Band
- The network channels can be freely attributed by the network operator. However the three following default channels must be implemented in every India 865-867MHz end-device. Those channels are the minimum set that all network gateways should always be listening on - 865.0625 Mhz, 865.4025 MHz, 865.985 Mhz. All of them have band width of 125KHz.
