Bluetooth : What is Bluetooth, how it works

Advertisement

Bluetooth is developed in accordance with the industry standard IEEE 802.15.1 for the data transfer between devices over short distances via radio technology. It was developed in the 1990s by Special Interest Group (SIG).Professor Jaap Haartsen and Dr. Sven Mattisson devised it for Erricson,later more advanced by Nokia and Intel.

Bluetooth is the interface through which small mobile devices like mobile phones and PDAs as well as computer and peripherals can communicate with each other. The main purpose is to replace cables between devices.

 

Technical Background behind Bluetooth

 

Equipment complying with the standards of the Bluetooth Short Range Devices (SRD) may be operated worldwide as a license-free protocol. Wireless LANs, cordless phones and microwave ovens can cause interference. It supports the transmission of voice and data. However, most devices during the transmission of speech due to the synchronous connection only three participants can participate. A backup and encryption of data are also possible.

Differences between Wi-Fi and Bluetooth technology

 

Bluetooth and Wifi are complementary technologies. This technology is designed to replace the cables between mobile phones, laptops and other computing devices and communication within a radius of 10 meters. A typical router with Wi-Fi radio can have a range of 45 m 90 m indoors and outdoors. Both technologies are expected to coexist:?Bluetooth technology is used as a cable replacement for devices such as PDAs, mobile phones, cameras, speakers, headphones and so on. Wi-Fi is used to access high-speed wireless Ethernet.

 

Versions of Bluetooth

 

  • Bluetooth 1.0 and 1.0B : Maximum data transfer rate of 732.2 kbit/s
  • Bluetooth 1.1 : Maximum data transfer rate of 732.2 kbit/s
  • Bluetooth 1.2 : Less sensitive to static interference, maximum data transfer rate of 1 Mbit / s
  • Bluetooth 2.0 + EDR : Maximum of 2.1 Mbit/s, backward compatible.
  • Bluetooth 2.1 + EDR : New features added such as Secure Simple Pairing.
  • Bluetooth 3.0 + HS : Theoretical transfer rate of 24 Mbit/s can be achieved.
  • Bluetooth 3.0 + EDR : Main new feature is Alternate MAC/PHY
  • Bluetooth v4.0 : This includes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols.
