Bluetoothklasse

Bluetooth classes refer to the power output and range specifications of Bluetooth devices. These classes are used to categorize devices based on their intended use and transmission capabilities. There are primarily three Bluetooth classes: Class 1, Class 2, and Class 3.

Class 1 devices are the most powerful, with a maximum transmission power of 100 milliwatts (mW) and a typical range of up to 100 meters (approximately 330 feet). These are often found in industrial or professional settings where longer-range communication is required.

Class 2 devices are the most common and represent a balance between power and battery life. They have a maximum transmission power of 2.5 mW and a typical range of about 10 meters (approximately 33 feet). Most consumer electronics, such as smartphones, headphones, and speakers, fall into this category.

Class 3 devices are the least powerful, with a maximum transmission power of 1 mW and a very short range, typically less than 1 meter (approximately 3 feet). These are less common and are usually found in specialized applications where extremely close-range communication is sufficient.

It's important to note that the specified ranges are theoretical maximums and actual performance can vary significantly depending on environmental factors like obstructions, interference, and antenna design. Device manufacturers specify the Bluetooth class of their products, allowing users to understand the potential communication range.
