  2. CONTENTS

  3. INTRODUCTION • Bluetooth-Originally started by Ericsson company. • It is named for Herald Blaatand. • Bluetooth-Wireless and Automatic technology simplifying art of communication. • Frequency used is 2.45 GHz

  4. DESCRIPTION • Bluetooth-Wireless technology providing link between mobile and electronic devices. • It operates on 2.45 GHz radio signals • Technology of Bluetooth concentrates on short range of communication.

  5. APPLICATIONS • Laptops • PDA’s • Headphones • Wireless printer adapter • Onboard Bluetooth adapter.

  6. BLUETOOTH BASICS • Bluetooth is low powered and low cost. • All the devices follow a uniform structure • Strength lies in handling data and video transmission simultaneously. • Specification- Bluetooth specification gives developers data link and application layer definitions

  7. BLUETOOTH BASICS • Spectrum-Bluetooth operates between 2.4 and 2.485 GHz using a frequency hopping spread spectrum. • Devices Connect through network called Pico nets. • Interference- is reduced using Adaptive Frequency Hopping allowing a better efficiency and greater performance.

  8. BLUETOOTH SOFTWARE • Blue soleil can be installed on personal computer or on personal digital assistant also • On a PC, it provides a lot of Extra wireless features. • It also has a graphical user interface (GUI). • On a PDA, provides basic Bluetooth profiles such as headset and hands free profile, personal networking (PAN) profile

  9. BLUETOOTH SOFTWARE • Bluetooth software can be installed and used on Bluetooth capable devices. • There exists different software for different devices like PDA , personal computer. • Enables the device to use technology at its fullest. • Best example is Blue soleil.

  10. HOW BLUETOOTH WORKS? • They normally operate at 2.45GHZ in license free globally available ISM radio band. • Advantage-worldwide availability and compatibility. • Disadvantage- devices must share the band with other RF emitters including automobile security systems, noise sources such as Microwaves • Solution- Frequency Hopping Spread Spectrum.

  11. TECHNICAL OPERATIONS • High speed, low powered wireless technology. • Circuits are Contained on a 0.9 cm square. • This offers 1MB link with security. • Each device offers unique 48 bit address from IEEE 802.15 standard.

  12. BLUETOOTH KEYBOARD • Bluetooth keyboard is one of major applications of Bluetooth technology. • It was first developed by Microsoft in 2002. • Today most of companies offer this type of keyboard, some of which companies include Dell, Apple.. • A Bluetooth keyboard and mouse combination will allow the user to work at distances of up to 30 feet. • There are mainly two types in this-wireless keyboard and virtual keyboard.

  13. VIRTUAL KEYBOARD • Virtual keyboard is projected on a flat, non reflective surface and keystrokes are accompanied by key clicking sounds that are simulated. • The keyboard has 63 keys and it measures only 295*95 mm with a height of 3.5 inches. • Keyboard works by producing a red diode laser light when keyboard is projected on surface.

  14. ADVANTAGES • Wireless • Inexpensive • Automatic • Interoperability • Low interference and energy consumption. • Share voice and data • Instant PAN • Upgradeable • Long lasting technology.

  15. DISADVANTAGES • Data rate and security. • More susceptible to Interception and attack. • Less range.
