technology communicate using radio waves, they do not need to be in direct line-of-sight. Bluetooth
devices must, however, be within 10 meters (33 feet) of each other, although the connection may be
subject to interference from obstructions such as walls or from other electronic devices.
Frequency Band: 2400 MHz - 2483 MHz
Maximum Radio Frequency Power: -6~+4dBm
