Question

What is the difference between Bluetooth and Infrared?

Answer 1

Actually, Bluetooth is just a term in technology wherein two computers (i.e. cellphones to laptops, laptops to laptops, etc) are connected with the use of radiation. these "blue" rays are also said to have the longest wavelength. meanwhile, infrared is really a technical term for a kind of radiation, which was adopted by technology. if you look at the rainbow, with red as the longest, it actually is the opposite here- infraRED has the shortest wavelength among rays.

Answer 2

Infrared works pretty good - like on TV remotes. Bluetooth proves humans are still thinking foreward and other humans figured out a way to sell it to you.  

Answer 3

Well, bluetooth is much better, cause it can exchange files up to 20 m of distance. Infrared needs to be right to the object when exchanging files. So if you're buying cell or something like that, buy ones with bluetooth!

Answer 4

bluetooth communicates with microwaves specifically spectrum in the 2.4 GHz to 2.4835 GHz range, while infrared uses infrared radiation.

basically microwaves have long wavelength then infrared

bluetooth can go thru walls, however infrared, you have to be in the line of sight to use it to communicate

see the electomagnetic specturm for more information.

Answer 5

infared  you can see but has a connection blue tooth usess a magnet

Answer 6

Bluetooth is a technology providing wireless personal area networks (WPANs) for small devices as cellphones or PDAs. It operates on the unlicensed 2.4-GHz industrial-scientific-medical (ISM) band, and has essentially been established by Ericsson. The Bluetooth Special Interest Group (SIG) was then founded with its original promoters being Nokia, IBM, Intel, and Toshiba. Today, approximately 2000 members are counted, amongst them Agere, 3Com, Lucent, and Microsoft. The name "Bluetooth" was chosen of the Denish King Harald Bluetooth.

The complementary of Bluetooth is the Infrared device of the Infrared Data Association (IrDA). During the last few months, it has been argued that Bluetooth has been created as a substitute for Infrared. Though, this is not quite true: Bluetooth has been invented as an enhancement of Infrared, especially in terms of low cost, small volume, low power, and the accomplishment of Infrared's limitations, such as the its unidirectional connections, the connectivity range of only meter or its limitation to point-to-point connections. Although Bluetooth has actually coped with these constraints, e.g. by omnidirectional connections, the connectivity range of up to 10 meters, or its capability for point-to-multipoint connections, the two technologies are quite complementary. While Bluetooth is very applicative for networking, Infrared is more appropriate for the direct connections, e.g. for exchanging business cards.

Answer 7

Infrared is "line of sight", Bluetooth is not.

Answer 8

In blue tooth, the mobile should  only should be in the distance of 5m. But in infrared the mob should be sticked together to send file.
