The maximum distance over which a Bluetooth device can connect to another Bluetooth device depends on several factors, including the class of the Bluetooth device and any physical obstructions that may be present.
Bluetooth devices are typically classified into three classes based on their power output:
- Class 1 devices have a maximum output power of 100 milliwatts (mW) and a range of up to 100 meters (328 feet).
- Class 2 devices have a maximum output power of 2.5 mW and a range of up to 10 meters (33 feet).
- Class 3 devices have a maximum output power of 1 mW and a range of up to 1 meter (3.3 feet).
It's important to note that these ranges are theoretical maximums, and the actual range you can achieve will depend on several factors, including the presence of physical obstructions (such as walls), the sensitivity of the Bluetooth receiver, and the quality of the Bluetooth implementation in the devices you're using.
In general, you can expect to achieve the maximum range of a Class 1 device (up to 100 meters) in an open, unobstructed environment, while the range of a Class 2 or Class 3 device may be significantly reduced by physical obstructions or other factors.
