What is the maximum range of Bluetooth 2.0 specification for Class 1 devices?

10 m
30 m
100 m
300 m

The correct answer is: 100 m

Bluetooth 2.0 specifies several classes of devices, each with different maximum transmission ranges. For Class 1 devices, the maximum range can reach up to 100 meters (approximately 328 feet). This range is designed for scenarios where a stronger signal is necessary, allowing devices to communicate over greater distances compared to lower classes. Class 1 devices are typically used in applications requiring longer connectivity ranges, such as industrial environments or specific consumer electronics where maintaining a connection at a distance is essential. In contrast, other classes like Class 2 (with a range of about 10 meters) and Class 3 (approximately 1 meter) cater to less demanding connectivity needs. By specifying this maximum range for Class 1, Bluetooth 2.0 ensures versatility in usage across different environments and applications.
