This document provides an overview of Bluetooth technology, including its history and logo, common applications and devices, classifications of device power and range, future developments, and conclusions. Key points covered are the merger of runes in the Bluetooth logo representing the initials of Harald Bluetooth, examples of Bluetooth headsets and cards in phones and laptops, classifications of Class I, II, and III devices by power output and range, the importance of integration into consumer products for success, and potential future improvements such as dynamic adjustment of master-slave relationships.

28. FUTURE OF BLUETOOTH
Success of bluetooth depends on how well it is integrated into
consumer products
- Consumers are more interested in applications than the
technology
- Bluetooth must be successfully integrated into consumer
products
- Must provide benefits for consumer
- Must not destroy current product benefits
Key Success Factors
- Interoperability
- Mass Production at Low Cost
- Ease of Use
- End User Experience

29. CONCLUSION
A new global standard for data and voice
Eliminate Cables
Low Power, Low Range, Low Cost Network Devices
Future Improvements
- Master-Slave relationship can be adjusted
dynamically for optimal resource allocation and
utilization.
