Bluetooth devices are classified into three classes based on their transmit power and range:
| Class | Range (approx.) | Power Output | Example Device |
| Class 1 | Up to 100 meters (328 feet) | Highest | Wireless projectors, industrial equipment |
| Class 2 | Up to 10 meters (33 feet) | Standard | Headphones, speakers, keyboards, mice |
| Class 3 | Up to 1 meter (3.3 feet) | Lowest | Hearing aids, remote controls |
Explanation:
- Class 1: Offers the longest range but also requires the most power. It's typically used in applications where a longer distance connection is necessary.
- Class 2: The most common class, providing a good balance between range and power consumption. It's suitable for most consumer applications.
- Class 3: Has the shortest range and uses the least power. It's used in devices where a very short-range connection is sufficient, such as hearing aids or remote controls.
