• Bluetooth 1.1 specifies a wireless technology in the unlicensed 2.45GHz Industrial, Scientific and Medical (ISM) band.
• Supports a range of 10 (100) meters
• Requires the use of spread spectrum transmission technology resistant to interference.
• Bluetooth deploys fast rate frequency hopping (FHSS) to provide robust data transmission
• Supports simultaneous transmission of both voice and data with approximately 1 Mbit/s (720 kbps) data rate
