As the name suggests, Sub-GHz utilizes radio frequency lower than 1 GHz. Sub-Gigahertz RF allows communication for longer ranges and lower power than Bluetooth and Wi-Fi, which is very suitable for IoT applications. However, unlike Wi-Fi and Bluetooth where both operate at 2.4GHz, Sub-GHz frequency varies in different part of the world. The benefit of Sub-GHz is the fact that the frequencies under 1GHz are less absorbed by the physical matter comparing to the higher frequencies used by Wi-Fi and Bluetooth. Further from there, the network can be expanded by using mesh Networking..
