Class 2

Bluetooth Class 2 devices, typically found in mobile devices and laptops, operate at a power level of 2.5 mW (4 dBm). The transmission range for these devices is approximately 10 metres. Class 2 Bluetooth devices are designed for short-range communication, making them ideal for personal area networks. They are energy efficient, which is crucial for battery-powered devices. However, their limited range means they may not be suitable for larger spaces or for applications requiring long distance transmission.
