Blue tooth technology
Man has always endeavored to improve his life style right from the invention of the wheel to the present day advancements in the field of technology. Communication between individuals through their devices has for long been the epitome of mans devolpment.Thus the technology of Blue tooth was created to improve and standardize data transfer as well as synchronize different and diverse mobile devices. The applicability presently is for short distance only.
How did this blue tooth technology develop In 1998 a group of major electronic companies that included Intel and Microsoft along with IBM, Toshiba, Ericsson, Nokia, and Puma Technology got together to develop this technology. The result was named blue tooth. This code name was derived from the name of the great Danish King Harald I Bluetooth who unified the present day countries of Denmark and Norway during the period 940-985 AD Blue tooth technology is home to connection of all electronic devices and appliances that exist presently. All you have to do is to click on the icon representing Bluetooth which is universally adopted all over the world and you can be linked to another device automatically.
Bluetooth is easy to use and in the confines of a room or a limited space makes wireless communication and networking between devices as easy as pressing a switch.
The companies involved in the development of blue tooth have created a single synchronization protocol. This protocol addresses the end-user problems that can arise due to proliferation of a multitude of devices that include mobile devices -- including smart phones, smart pagers, Pads, handheld PCs, copiers, printers and notebooks..
Bluetooth wireless technology has created a de facto standard that adheres and applies to all small and low-cost, short range radio links between mobile PCs, mobile phones and other portable devices. Further development of blue tooth technology comes under the purview of SIG known as the Bluetooth Special Interest Group. This is a grouping that has as its members the leaders in the telecommunications, computing, and networking industries. This group is further devolping Bluetooth technology for the use of mobile phones, computers, and personal digital assistants (Pads). Using this technology, users can totally coordinate all mobile and fixed computer devices.
Bluetooth is can be defined as a standard wireless communications protocol between devices in a personal area network (PAN).This is carried out by using radio frequencies over a short distance up to about 32 ft or 10 meters. The radio frequencies used are in the 2.4 GHz band.Thus the requirement of line of sight is non existent. Another important aspect of this technology is that it supports multipoint activity and not just from one point to another.
Present day Blue tooth supports speeds of 1-2 Mbps but higher speeds can be expected in the years to come.
Another major advantage is the cost involved in blue tooth as chip sets which is $ 10 t0 $15 if procured in large quantities.
Another major impetus to further blue tooth technology is the fact that nearly 1800 members from the related industry are part of this initiative.
An important aspect and question mark about this technology is its relevance to security of communication. It can be emphatically stated that Bluetooth is extremely secure as it t employs several layers of data encryption and user authentication measures. To help in this secure communication combination of the Personal Identification Number (PIN) and a Bluetooth address are used to identify other Bluetooth device. Bluetooth security can be further enhanced by the use of data encryption. Bluetooth radios use a fast frequency-hopping that works over many frequencies within the 2-4GHz band through the FHSS technique that only allows synchronized receivers to access the transmitted data Interference from other RF sources is minimal as blue tooth frequencies are switched at a very rapid pace at the rate of nearly 1600 times per second. Bluetooth is thus a potent and viable communication system.
Blue tooth technology has myriad uses and its use is easily extended to the home from the office
You can create a wireless surround sound system, as well as transfer pictures straight from your Bluetooth mobile to other devices without cumbersome cables and other paraphernalia.
T oday Bluetooth wireless technology, is the chic aspect of office work. The wires have become non existent and Pads are synchronized with computers to share calendars and contact lists directly with computers.
Data is transferred through Bluetooth technology at the rate of 721 Kbps.This contrasts with the average speed of parallel and serial ports, respectively from 3 to 8 times.. This bandwidth is quite capable of transmitting voice, data, video and still images from one device to another.
An important point to remember is that Bluetooth technology provides the personal connectivity while the user is on the move and traveling. He can thus access important information and communicate at any time. New devices and technologies are coming to market and further revolutionary developments can be expected. Its a dynamic world.However the use of blue tooth technology in an aircraft is still under consideration. Lastly Bluetooth wireless technology is the best wireless technology for gaming. Gaming devices with built in Bluetooth technology are a real boon to users. These devices allow the player to pay the game with any other player at any location. Because no wires are required, gamers can find other players easily and play friendly games. If the need arises you can also play the game with a partner anonymously.
Over the long term manufacturers will also benefit from this technology as they can replace multiple connection ports with a single Bluetooth module. The Bluetooth SIG is in the forefront of further development. The Bluetooth Special Interest Group (SIG) is a privately held, non-profit trade association. The Bluetooth SIG includes Promoter member companies like Ericsson, Intel, Renovo, Microsoft, Motorola, Nokia, and Toshiba, and thousands of Associate and Adopter member companies who have become members much later. The future can really be exciting.
