AWS IoT Core for LoRaWAN - support for WW_2G4 band (2.4GHz)

AWS IoT Core for LoRaWAN currently supports four specific frequency bands: EU863-870, US902-928, AU915, and AS923-1. These are all sub-GHz bands commonly used in different regions around the world. The EU863-870 and US902-928 bands are typically used in Europe and North America respectively, while AS923-1 is used in countries like Australia, New Zealand, Japan, and Singapore, and AU915 is used in Australia, Argentina, and other South American countries.

Based on the available information, there is no mention of current support for the WW_2G4 (2.4GHz) band in AWS IoT Core for LoRaWAN, nor is there any indication of plans to add support for this band in the future. The documentation specifically lists only the four sub-GHz bands mentioned above.

For implementing FUOTA functionality, AWS IoT Core for LoRaWAN does support firmware updates over-the-air based on the LoRa Alliance specifications, including multicast capabilities for updating multiple devices simultaneously. However, this functionality appears to be limited to the currently supported frequency bands.

If you're planning to implement FUOTA over 2.4GHz LoRaWAN, you might need to explore alternative solutions or continue using The Things Industries as your Network Server for devices operating in that frequency band until AWS potentially adds support for it.
