Introduction To The Bluetooth Technology
Bluetooth is a short range, wire free, secure and international standardized wireless technology that provides wireless communication system between the Bluetooth enabled devices in a short ranged network. Bluetooth technology is a short range wireless technology that was developed by the collaboration of mobile phones and IT companies such as Nokia, Intel, Toshiba, Erickson and IBM. Bluetooth develops short range wireless connections between the laptops, handheld pcs, wireless communication devices and mobile phones. Bluetooth is only available to the personal area networks in an office or a home network.
It reduces the usage of power as compared to the Wi-Fi. Bluetooth is an international standardized technology that is used for the wireless communication between the Bluetooth held devices such as mobile phones, digital camera, laptops, desktop computers, keyboard, mouse, mp3 players, video cameras and other devices.
Bluetooth is free technology and it is provided by the mobile phone operators who are having the capability of GSM and CDMA technology. Bluetooth uses radio waves frequency as a medium and is suitable for the 1, 10 and 100 meters distance. Every Bluetooth enabled devices such as mobile phones, laptops, digital cameras, video games consoles have built-in microchip. There are about more than 1800 members of the Bluetooth consortium from all over the world. Every GSM and CDMA mobile operates must provide the features of the Bluetooth technology to its users. Like the Bluetooth, Wi-Fi uses the same frequency but the power consumption of the wi-fi is high so it produces more powerful signals.
Bluetooth uses radio waves that operate at 2.4 GHz bands. The personal computers must have built-in dongle in them to use the Bluetooth technology. Bluetooth is also used to transfer the files from the mobile phones or PDA devices to the computers. Also, in a meeting if you want to share the digital business cards among the participants of the meeting you use Bluetooth to transfer the files. Microsoft Windows XP with the service pack 2 has the built-in support for the Bluetooth technology. Bluetooth defines the wireless standards to maintain the secure data communication.
The master Bluetooth device can communication with the seven other Bluetooth enabled devices. Different devices support different standards of the Bluetooth technology. The research on the advanced Bluetooth is in progress for the Bluetooth version 3.0 to provide the high speed connections.
Bluetooth technology also provides support for the VOIP technology. The Bluetooth headset provides the wireless extension to the Bluetooth devise. A typical Bluetooth device consist of RS transceiver, protocol stacks and base bands and It does not require to install the additional drivers to use the Bluetooth technology and it can connect all the office peripheral such as computer with printer, computer with scanner and computer with laptop. Among the other advantages of the Bluetooth technology is the automatic synchronization of the desktops, mobile phones and other Bluetooth held devices. Another popular use of the Bluetooth is in the cars and automotives. The most commonly Bluetooth held devices are mobile phones, personal computers, laptops, headsets, access points, car kits, speaker phone, streaming video, MP3 players, SIM cards, Push-2-talk, PDA and digital camera.
By this technology, mobile data can be used in the different applications. It provides the speed of 1-2 Mbps. Bluetooth’s small microchip can be built in the devices and it can also be used as the external adapters and used for the different network communication devices. Bluetooth enabled devices can change their frequency very rapidly so they can be saved from the external interference. Bluetooth enabled devices have built in security features and they use pin code and 128 encryption. If the two wireless devices follow the Bluetooth standards they can communicate with each other without any external devices or wires. The more enhancements are in progress in this technology to provide most robust, state-of-the-art, high speed and secure connections to the mobile users.
