1.6 What are the main differences between Bluetooth 1.2 and Bluetooth 2.0
EDR?
The main motivation for the release of the new version was to improve existing usage scenarios that
require increased data throughput. Scenarios requiring higher throughput may be image transfer,
printing and synchronizing. In these cases the new release makes the Bluetooth wireless technology
faster and better for the consumer to use.
The main features offered with these enhancements are:
• Backwards compatibility with earlier versions.
• 3 times the transmission speed makes existing usage scenarios better.
• Lower power consumption through reduced duty cycle.
• Simplification of multi-link scenarios due to more available bandwidth.
• Further improved BER (Bit Error Rate) performance.
