3. What is Bluetooth It is a cable replacement technology.
Wireless communication between various devices within a small area.
Used to swap data and synchronize between various devices.

4. How it works
Bluetooth is based on low cost, short-ranged radio link, operates in Radio band of 2.4GHz , and provides a range of 10 meters.
Connections can be point-to-point or multipoint.
Devices connected to each other, they form a personal area network (PAN) called the Pico net.
Each Pico net can have a master, and up to 7 active and 255 parked slaves.
Different Pico nets are connected using a common device and such networks are called scatter net

8. Frequency Band Diff Frequency ranges for diff countries.
Europe & USA MHz.
Japan MHz.
Spain MHz.
France MHz.
SIG Working towards harmonization of frequency.

9. Applications of Bluetooth
tremendous potential in moving and synchronizing information in a localized setting.
The Bluetooth technology connects all your office peripherals wirelessly.
Bluetooth allows us to have THREE way phones
Automatic Message Delivery.
Have automatic synchronization of your desktop, mobile computer, notebook and mobile phone.
Upon arriving at your home, the door automatically unlocks for you, the entry way lights come on, and the heat is adjusted to your pre-set preferences

11. Current state of technology
Technology has moved fast in terms of standard adoptions with release of chipsets and demo products.
Like Ericsson’s Bluetooth headset with 20gms of weight can be used with Ericsson T28, T28 WORLD and R320 cellular phones.
Nokia Bluetooth headset with 10 Meters range.
Nokia and Fuji film had developed a prototype Mobile Imaging technology.
AutoPC is a Windows CE based device that combines a computer with a car radio.
Xircom’s Flash product can transfer voice data files at 721 kb/seconds.

13. Future Outlook Meets basic connectivity in close proximity
More than 1800 manufacturers have joined.
More than 670 million Bluetooth device.
Use of WAP,Smart phones & handheld devices.
Replacing multiple communication ports with single Bluetooth module.

14. Software Development Tools
XTNDAccess Bluetooth SDK
Impronto Simulator from Rococo Software
Cambridge Silicon Radio's Development kit 
RAPPORE Technology's SDK

15. Bluetooth versus Wireless LAN
Bluetooth ranges up to 30 feet
Speed 1-2 MBPS
Less expensive
Started in 2002
WIRELESS LAN
ranges Up to 200 feet
11-54 MBPS
Very expensive
Widespread market

16. Conclusion
Though Bluetooth is one of the greatest success in the wireless communication world, still it has not been able to finalize the problem completely.
