Bluetooth Technology

  1. 1. Data Communication& Networking BLUETOOTH TECHNOLOGY
  2. 2. Present by:- UMMAR AHMED MATEEN AHSAN UMER TAHIR BS IT 4th Sec ‘A’ University of Gujrat
  3. 3. Contents:-  What is Bluetooth?  History?  How Bluetooth technology works?  What is Piconet?  Advantages of bluetooth?  Disadvantages of bluetooth?  Future of bluetooth technology?
  4. 4. Bluetooth technology:  Bluetooth is a wireless technology used for exchanging data over short distances using radio waves.  Bluetooth technology eliminates the need for numerous cable attachments.  Bluetooth communicates between devices within a range of 10 meters.
  5. 5. Bluetooth(cont)  Bluetooth operates in the range of 2400–2483.5 MHz.  this technology enables users to easily connect a wide range of computing & telecommunication devices.
  6. 6. History:-  This tecnology was officially introduced in 1998 and its basic purpose was to be a wire replacement technology in order to rapidly transfer voice and data.  Bluetooth is managed by the Bluetooth Special Interest Group which has more than 20,000 member companies in the areas of telecommunication, computing, networking, and electronics.
  7. 7. How it works:  Bluetooth is a high speed,low power microwave wireless link technology designed to connect communicating devices,connections can be point to point or multipoint.  Unlike infra-red, bluetooth technology does not require any line of sight positioning of connected devices like infra-red.
  8. 8. How works(cont)  Two bluetooth products can exchange their addresses and capabilities just after coming within the range of 10 metres.  can be extended 100 metres by increasing power,it supports data speed of up to 721 kbps.
  9. 9. How works(cont)  The bluettoth modules can be either bulit into electronics devices or used as an adaptor
  10. 10. How works(cont)  Bluetooth devices are protected from radio interference by changing their frequencies up to a maximum of 1600 times a second  a technique used known as frequency hopping.
  11. 11. Piconet: Piconet is the most important factor in bluetooth connectivity. It is simply a collection of devices connected through bluetooth technology.
  12. 12. Piconet(cont)  While establishing a piconet one unit is act as master and other as slaves for the duration of piconet connection.  The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies.
  13. 13. Advantges of bluetooth:-  By installing bluetooth in your office you can do complex tasks of networking b/w the computing devices.Each bluetooth device can connect to 200 other devices.  It connect all your peripherals wirelessly.
  14. 14. Advantages(cont)  With bluetooth enabled,we can send videos,images,voice,document etc from any communicating device like(mobile phone,digital camera etc)  Bluetooth devices are wireless.  Bluetooth technology is inexpensive.  Low energy consumption  Bluetooth is automatic.
  15. 15. Disadvantages:-  Bluetooth devices cannot be connected with more than one devices at a time,as it finds problem in discovering the intended recipients device.  Bluetooth has low data rate i.e 1Mbps in comparison to infra red i.e 4 Mbps.
  16. 16. Future of bluetooth:-  Many of us think that Bluetooth is going to be here stay,but its wrong.  Bluetooth will be able to complete all the other wireless technologies such as WiFi,networking,infrared data association etc.
  17. 17. THE END
