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

How it worksBluetooth 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

Frequency BandDiff Frequency ranges for diff countries.Europe & USA-2400-2483.5 MHz.Japan-2471-2497 MHz.Spain-2445-2475 MHz.France-2445-2483.5 MHz.SIG Working towards harmonization of frequency.

Applications of Bluetoothtremendous 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 phonesAutomatic 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

Current state of technologyTechnology has moved fast in terms of standard adoptions with release of chipsets and demo products.Like Ericssons 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. Xircoms Flash product can transfer voice data files at 721 kb/seconds.
