Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 metre, 10 metres, 100 metres) based on low-cost transceiver microchips in each device.

Bluetooth lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, as long as the received transmission is powerful enough.

Class Maximum Permitted Power

(mW/dBm) Range

(approximate)

Class 1 100 mW (20 dBm) ~100 meters

Class 2 2.5 mW (4 dBm) ~10 meters

Class 3 1 mW (0 dBm) ~1 meter
