Today with world becoming flatter and flatter the first aspect that people look for in any gadget is the bluetooth connectivity. Well it all started way back in the 10th century when Harold Bluetooth wanted a code name for the Trade Association and after the much discussion finally the name “Bluetooth” was assigned looking at the future of wireless technology. While the Bluetooth specification was developed in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson Mobile Platforms in Lund, Sweden. Since then the technology has evolved tremendously.
Bluetooth is a wireless protocol utilizing short-range communications technology making room for data transmission such as videos, photos or any data from fixed mobile devices creating personal area networks (PAN’s). In simple words bluetooth technology helps in connecting multiple devices and providing best possible synchronisation. You can transfer and exchange any piece of information or data between devices such as mobile phones, laptops, printers, GPS receivers and many others just to mention with bluetooth technology.
Initially bluetooth 1.0 and 1.0B versions came into picture which had many problems that gave space for bluetooth 1.1 IEE Standard 802.15 helping mobile phones to connect efficiently. Then came bluetooth 1.2 v which had several enhancements to the 1.1v. Finally the most advanced ones which are used today are bluetooth 2.0v and bluetooth 2.1v. The connectivity range can be 10 metres or 100 metres depending on the class of the bluetooth device in concern.
The unbelievable reach of bluetooth technology is really commendable. It started with mobile phones making them capable of transferring videos, music and other digital content to other devices. And now we observe that bluetooth watches which can perform all bluetooth function such as receiving and rejecting calls with buttons on the watch. What’s more the trend has reached to the making of a bluetooth-enabled umbrella that lets you freely take and make phone calls when it’s raining ensuring you that your handset doesn’t get wet. It also includes entertainment applications such as radio, small keyboard.

The Unbelievable Yet True Reach of Bluetooth Technology
February 5th, 2010A Look at Bluetooth Technology
January 21st, 2010
Bluetooth technology is a wireless, radio based communication technology. Bluetooth enabled electronic devices are capable of successfully communicating, at a time, with as many as seven other Bluetooth enabled devices within a short range of distance — usually ranging from about 1 to 10 meters, depending upon the radio class. This technology is always improving, but some limitations still remain. For example, the maximum range of a single Bluetooth device to another one is 30 feet.
Bluetooth is designed specifically for linking between devices (such as printers, mobile phones, home appliances, wireless headsets, mouses, keyboards, and so on), computers, or PDAs to one another, without using a wired connection. The technology is also becoming more and more commonly utilized in mobile phones, allowing them to communicate between computers or PDAs, and is especially widespread in hands-free accessories like Bluetooth headsets.
This short range wireless technology was developed by the collaboration of mobile phones and IT companies such as Intel, Nokia, Toshiba, Erickson and IBM. It is also designed to have a very low power consumption. This is further reinforced by allowing radios to be powered down when they are inactive.
You can think of Bluetooth as an ad hoc technology that requires no fixed infrastructure and is easy to install and set up. You don’t need any wires to get connected. It is most commonly known by consumers for providing the ability to talk on a wireless headset. And one of the nice features of Bluetooth is that it is not manufacturer specific.
