What is Bluetooth? Bluetooth is an industrial specification for wireless personal area networks. It’s the name for a short-range radio frequency technology that operates at 2.4 GHz. The effective range of Bluetooth devices is 10 meters. It provides us to connect and exchange information between devices such as mobile phones, laptops, personal computers, printers, GPS receivers, digital cameras, and video game consoles.
<ul><li>Bluetooth was created years ago as an international effort, licensed from an official body, to produce a smart, short-range device to device radio communications network that could be connected and broken at will. The idea was to simplify pairing mobile devices together, to make it easy to find a Bluetooth device and to bring low-power-consumption radio communications to a whole new range of gadgets, including hands-free headsets. </li></ul><ul><li>It was smart, it was relatively cheap, and it did exactly what it said on the box. Of course there were glitches, and some early devices had difficulty talking to each other or even maintaining a good connection, but these were slowly ironed out. </li></ul>History
History <ul><li>When Bluetooth was officially introduced in 1998 by Ericson communications pvt ltd ., its basic purpose was to be a wire replacement technology in order to rapidly transfer voice and data. </li></ul><ul><li>Many doubters who believed Bluetooth would be a distant memory in just a couple of years. </li></ul><ul><li>However, multiple years have passed and Bluetooth continues to make strides and advancements everyday. </li></ul><ul><li>A lot has changed since the first Bluetooth Core Specification Version was introduced in 1998. </li></ul><ul><li>Over the past couple years Bluetooth technology has really begun to take giant leaps forward. </li></ul>
History <ul><li>In 2003, the Bluetooth SIG began a major overhaul of the Bluetooth specification with the announcement of version 2.1. Then, </li></ul><ul><li>in 2004, Bluetooth version 2.0 + EDR (Enhanced Data Rate) was introduced. Devices using version 2.0 + EDR began to hit the market in late 2005. </li></ul><ul><li>For a listing of the different Bluetooth versions and the various features/benefits they provide, please click Bluetooth Core Specification Versions </li></ul>
History Bluetooth can be used to wirelessly synchronize and transfer data among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone.
History The word "Bluetooth" is taken from the 10th century Danish King Harald Bluetooth , he had been influential in uniting Scandinavian Europe. The developers of this wireless technology first used the name "Bluetooth" as a code name, but as time past, the name stuck. The founders of the Bluetooth SIG felt the name was fitting because: 1) Bluetooth technology was first developed in Scandinavia, and 2) Bluetooth technology is able to unite differing industries such as the cell phone, computing, and automotive markets. Also it simplifies and combines multiple forms of wireless communication into a single, secure, low-power, low-cost, globally available radio frequency.
Reason for its logo. A Scandinavian firm originally designed the logo at the time the SIG was formally introduced to the public. Keeping to the same origin as the Bluetooth name, the logo unites the Runic alphabetic characters "H", which looks similar to an asterisk, and a "B", which are the initials for Harald Bluetooth. If you look close enough you can see both embodied in the logo. History
<ul><ul><li>Waiting for Bluetooth with its promise to provide wireless connectivity between virtually every electronic device on the planet, Bluetooth technology has massive business potential.. Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN. This paper will give some advantages and disadvantages of Bluetooth . </li></ul></ul>Now
Now <ul><li>A limited, but growing number of devices use Bluetooth at present. Devices that are starting to have Bluetooth connectivity built in include : </li></ul><ul><li>Digital cameras and camcorders </li></ul><ul><li>Printers </li></ul><ul><li>Scanners </li></ul><ul><li>Cell Phones </li></ul><ul><li>PDAs </li></ul><ul><li>Laptops </li></ul><ul><li>Keyboards and Mice </li></ul><ul><li>Headsets </li></ul><ul><li>In-car handsfree kits </li></ul><ul><li>GPS navigation receivers </li></ul><ul><li>Home appliances (microwaves, washers, driers, refrigerators) </li></ul><ul><li>In addition, add on Bluetooth adapters are available for computers (e.g. with a USB interface) and for PDAs (e.g. SD cards). </li></ul>
Bluetooth Wireless Networking Explained If your PC doesn't have Bluetooth built in, a USB adapter is inexpensive and simple to add. But don't buy a D-Link adapter. Their service is dreadful! Part 1 of a series on Bluetooth - see also How to Choose a Bluetooth Headset The number of ways to wirelessly connect an increasing number of formerly wired devices is becoming confusing. Wi-Fi, 802.11a, 802.11b, 802.11g, GPRS, IrDA and Bluetooth are just some of the terms now being used to describe different types of wireless connectivity. This article explains the differences between the main types of wireless connectivity, and explains how Bluetooth can be useful for you. Now
Future Ever want to know if u can use your cell phone as a mouse? Well this is the right slide u have come to. Bluetooth is now introducing a mouse where u can use your own phone as long as u Get the right Data installed on your cell phone.
Future We all know how cool and sophisticated USB sticks really are. Well Bluetooth have seen their future and have come up with this cool design, which is; The USB network stick. Everything that a USB could do before and now it can be opened by other uses through out the whole world (according to which code to put in).
Future Wireless headsets have just been upgraded even more: If u buy the new headset it will be able to connect to a device automatically (such as mobile phone, laptop or PC). By doing this u will have need to have programmed it before hand, putting in the right codes. The range is outrageous and can come up to a mile which means you could get your headset and listen to some of your friends television's (doesn't include picture I'm afraid).
