Bluetooth, now approaching its 12th generation at Bluetooth 5.2, has been carefully developed and segmented to cater to a growing number of use cases and applications. Bluetooth Class is the categorization which separates Bluetooth products by their transmit power, which has an effect on power consumption and overall range. They range from Class 1 (with an average range of ~320 feet) to Class 3 (~1.5 feet), and they have very different purposes and uses for different customers.
