Bluetooth Technology

Bluetooth technology is a type of the wireless technology that eliminates the need for the number of inconvenient cables and devices that are used to connect the computers, mobile phones, digital cameras, handheld devices and new digital appliances. Bluetooth enables the users to connect to a wide variety of telecommunication and computing devices easily, without cables. It makes rapid ad hoc connections, automatic unconscious connections between two or more digital devices. Bluetooth provides the opportunity of using the mobile data in different applications. Bluetooth makes wireless communication between the two devices in a localized area of a room of office or home very easily. Bluetooth technology uses radio-based links and all the connections between the devices and invisible and instantaneous.

By Bluetooth technology your laptop can send print request to a printer in your next room. Bluetooth is actually a standard for wireless communication between the devices in a relatively small area and it is therefore works fine in the personal area network (pan) using radio frequency. Any two devices that follow the Bluetooth standard can communicate with each other. A number of the Bluetooth devices like digital camera, mobile phone and handheld pc can form a network. You can send emails to your mobile phones from your laptop without any physical connect between your laptop and your mobile phones.

Features of Bluetooth technology

  • Bluetooth technology uses radio waves for communication in 2.4 GHz
  • It supports multi point communication not just point to point.
  • Bluetooth works in a small area of 10-15 meters.
  • Bluetooth offers speed of 1-2 mbps.
  • Bluetooth chipsets are less expensive though more expensive than IrDA.

How Bluetooth technology works

Bluetooth is a high speed wireless link technology that uses the radio waves. It is designed to connect the mobile phones, laptops, hand held devices and portable equipments with almost no work by the end users. Unlike infrared Bluetooth does not require line of sight between the connecting units. Bluetooth technology is a modified form of the current wireless LAN technology and it’s more acceptable for its relative small size and low cost. Bluetooth devices are protected from the external interference because they change their frequency up to 1600 times in a second. Bluetooth radio technology provides the bridge between the existing data network. Bluetooth guarantees security at the bit level and the authentication is controlled by the end user by using 128 bit key. An important face of the Bluetooth technology is that it instantly forms a network when two or more devices come closer in the range of each other.

Bluetooth technology benefits

Bluetooth technology is a convenient choice of communication in a wire free, short range environment. Bluetooth is a globally available standard for connecting the devices like mobile phones, digital cameras, laptops, mp3 players, cars, stereo headsets etc. Bluetooth enable devices do not need to install any drivers. The key benefits of the Bluetooth wireless technology are its built-in-security, low cost, easy of use, robustness, and ad hoc networking capabilities. The Bluetooth wireless technology is available globally. Many manufactures from the different companies are busy to implement the technology in their products. Bluetooth technology operates in the 2.4 GHZ, one of the unlicensed, industrial and scientific radio bands. Bluetooth technology is a free of charge service but your mobile phones set should support the GSM and CDMA technology.
