  • 1. INDEX  BLUETOOTH INTRODUCTION  TYPES  TECHNOLOGY  BLUETOOTH Vs WiFi  ADVANTAGES OF BLUETOOTH  DISADVANTAGES OF BLUETOOTH
  • 2. What is BLUETOOTH: Bluetooth is a wireless technology used to transfer data between different electronic devices. This technology eradicates the use of cords, cables, adapters and permits the electronic devices to communicate wirelessly among each other. (or) Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user.
  • 3. Who Started Bluetooth?  Bluetooth was invented in 1994 by Ericsson.  The company later started working with a larger group of companies called the Bluetooth Special Interests Group, or "SIG," to develop the technology into what it is today. Bluetooth Special Interest Group (SIG) 5 founding members Ericsson, Nokia, IBM, Intel & Toshiba  Bluetooth is not owned by any one company and is developed and maintained by SIG.  The name Bluetooth came from a code name originally used by SIG for the project and is a reference to a 10th century Danish king named Harold Bluetooth, who was responsible for uniting Norway, Sweden, and Denmark.  Promoter’s Group 3COM, Lucent, Microsoft, Motorola  • Now over 1900 members
  • 4. It comprises of a base band processor, a radio and an antenna . The base-band processor converts the data into signals, the antenna of another blue tooth device, within at least 30 feet distance, receives a transmitted signal in the air. What is Bluetooth Technology:
  • 5. Types Of Bluetooth Devices: Head Set In-Car Bluetooth System Bluetooth Equipped Printer Bluetooth Equipped Web Cam Bluetooth GPS System Bluetooth Key Board Bluetooth Mouse
  • 6. BLUETOOTH Vs WiFi
  • 7. Class 1 Class 2 Speed 732 kbps 732 kbps Distance 100 mtrs 10 mtrs Frequency range 2.4 Ghz 2.4 Ghz 802.11b 802.11g Speed 11 Mbps 54 Mbps Distance 100 mtrs 100 mtrs Frequency range 2.4 Ghz 2.4 Ghz
  • 8. LOW POWER CONSUMPTION LOW COST DESIGNATED FOR SHORT RANGE NETWORK REPLACES PARELLEL/SERIAL CABLES IP BASED DATA TRANSMISSION SUPPORT MULTIPLE DEVICE ON ONE NETWORK MEDIUM TO LONG RANGE HIGH DATA RATES PROS CONS LOWER DATA RATES LIMITED TO 7 DEVICES ON A NETWORK HIGHER POWER CONSUMPTION MORE EXPENSIVE
  • 9. ADVATAGES OF BLUETOOTH:  These have Replaced cables for transferring Information from one Electronic Device to another one.  These have decreased Strain like carrying phones while talking, making hands free to do another work.  This is cheaply Available.  It’s Mobility is also very Important as it doesn’t need any power outlet or Internet connection or any other items.
  • 10. DISADVANTAGES OF BLUETOOTH:  Data sent between two Bluetooth devices is very slow compared with Wi-Fi transfer Rate.  Range Of a Bluetooth Device is 15-30 feet depending upon the Device.  Security is Biggest Disadvantage as transfer takes place through radio waves and a hacker can easily hack it.  Battery usage is also a problem, it will make device out of power before it would have if Bluetooth was not powered on.
