Bluetooth wireless Technology is a type of technology that eliminates the need for the number of inconvenient cables and devices used to connect computers, mobile phones, digital cameras, handheld devices, and new digital instruments. Bluetooth enables users to connect to a wide range of telecommunications and computing devices easily, without cables.
This allows quick ad hoc connections, automatic unconscious connection between two or more digital devices. Bluetooth provides an opportunity to use mobile data in a variety of applications.Bluetooth enables wireless communication between the two devices in localized areas of a room or Home Office very easily. Bluetooth uses links based on the radio and all connections between devices and invisible and instantaneous.
Using Bluetooth technology, you can send your laptop on the next request printer print rooms.Bluetooth is a standard for wireless communications between devices in a relatively small area and therefore works well in the personal area network (pan) using radio frequencies.
Two devices that follow the standard Bluetooth you can communicate with other Bluetooth devices, number such as digital camera, mobile phone and Pocket pc you can create a network, you can send emails to your mobile phone from your laptop without any physical connection between your laptop and your mobile phone.
Features using Bluetooth technology
about Bluetooth Technology uses radio waves to communicate in the 2.4 GHz
It supports multi point communications is not just a point to point.
about Bluetooth works in a small area of 10-15 metres.
about Bluetooth offers a speed of 1-2 mbps.
about Bluetooth chipsets are cheaper, though more expensive than IrDA.
How Bluetooth technology works
Bluetooth is a wireless high speed technology that uses radio waves. To connect mobile phones, laptops, hand-held devices, and portable device with almost no work is designed for end users. Unlike infrared Bluetooth does not require line of sight between Bluetooth connection unit is adapted. current technology for wireless LANs, and is more acceptable for its relative small size and low costs.
Current circuits are included on a circuit board 0.9 cm square and much smaller versions of a single chip is in development and will soon be in use.It is expected that the costs of Bluetooth Bluetooth chip quickly fall. should be equipped with many Bluetooth devices In a small and inexpensive transmitters have been placed in digital equipment.Radio waves work on 2.45 GHZ band, the Bluetooth device.Bluetooth supports data rates up to 721 kbps and 3 voice channels.Bluetooth chip can be either built facilities, or they can be used as an adapter you can use your computer via USB port.Each Bluetooth device address is 48 bit from the standard IEEE 802.3 and the Bluetooth connection can be either a point or multi point.Bluetooth range is 10 meters, but it can be extended up to 100 m increase in performance.
Bluetooth devices are protected against external interference, because they may change their frequency up to 1600 times in the second.Bluetooth technology allows Wireless bridge between existing data network.Bluetooth guarantees security at the level of bits and is managed by the end user authentication using 128 bit key.Important face of Bluetooth technology is that it immediately makes network, where two or more devices come closer range from each other.
Benefits of Bluetooth technology
Bluetooth is a convenient choice of communication, in an environment free of charge, short range Bluetooth wire is globally available standard for connecting devices such as mobile phones, digital cameras, laptops, MP3 players, stereo headphones, car, etc. to enable Bluetooth device do not need to install any drivers key benefits wireless technology Bluetooth is its integrated-in-security, low cost, easy to use, robustness and ad hoc networking abilities.
Bluetooth wireless technology is globally available. Many products from different companies are busy to implement technology in their products. "Bluetooth technology operates in 2.4 GHZ band, one of the unlicensed industrial, scientific, and Radio UserLand. Bluetooth technology is free of charge service, but your mobile phones set should support GSM and CDMA technology.
Mobile phones are now built in capabilities and functionality of Bluetooth. Bluetooth is available in a range of different devices like mobile phones, automobiles, medical, and industrial enterprises, etc. because of the key features of Bluetooth technology as well as low power consumption, low cost and wireless functionalities make more popular. Bluetooth requires no fixed infrastructure and is very easy to install and Setup.
No wires to connect a Bluetooth device can connect to other Bluetooth devices at any time if you are in your area. "Bluetooth wireless technology is widely supported and today is a secure wireless network standard Bluetooth integrated safety features such as 128-bit encryption and PIN code authentication if the Bluetooth device is identified by a pin code when you first connect.
