BLUETOOTH TECHNOLOGY
[attachment=43715]
INTRODUCTION:
Bluetooth is a method for data communication that uses short-range radio-links to replace cables between computers and their connected units. Many companies have been mulling over this idea, but it was Ericsson Mobile Communication that finally (in 1994) started the project that was named Bluetooth.
As computerized implementations have grown and become increasingly more common in our environment, there has also been a growing need for cables of varying kinds, to tie all these units together and ensure communication between them. These cables, when they grow into a multitude, are not only unsightly but also increasingly cumbersome to handle, both directly and (even more so) indirectly.
THE AIM OF BLUETOOTH:
The aim has been set quite height. It is to arrive at a specification for a technology that optimizes the usage model of all mobile computing and communications devices, and providing:
• Global usage
• Voice and data handling
• The ability to establish ad-hoc connections
• The ability to withstand interference from other sources in open band
• Very small size, in order to accommodate integration into variety of devices
• Negligible power consumption in comparison to other devices for similar use
• An open interface standard
• Competitively low cost of all units, as compared to their non-Bluetooth correspondents.
HOW BLUETOOTH WORKS:
When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols.
There are lots of different ways that electronic devices can connect to one another. For example:
• Component cables
• Electrical wires
• Ethernet cables
• ¬Wi-Fi
• Infrared signals
The art of connecting things is becoming more and more complex every day. In this article, we will look at a method of connecting devices, called Bluetooth. that can streamline the process. A Bluetooth connection is wireless and automatic, and it has a number of interesting features that can simplify our daily lives.
HOW TO USE BLUETOOTH GENERALLY:
1. Activate Bluetooth on your mobile phone (usually found under the Settings menu) and set it to be discoverable or visible.
2. On the PC, find your Bluetooth program manager (in Windows XP and Windows 7, look under My Computer > My Bluetooth Connections; in Vista, look for Bluetooth devices in the Control Panel; on a Mac, go to System Settings > Bluetooth).
3. In the Bluetooth program, select the option to add a new connection or device, which will make the computer search for available Bluetooth devices and find your phone.
4. When your mobile phone appears, select it to connect/pair it to your laptop.
5. If prompted for a PIN code, try 0000 or 1234 and enter it on both the mobile device when prompted and your laptop.
6. When the phone has been added, you will be asked what service to use. Choose PAN (Personal Area Network). You should then have a working Internet connection.
