INFRARED:::::::: Infrared have a frequency in the electromagnetic spectrum in the range just below that of red light. Objects radiate infrared in proportion to their temperature. Infrared radiation is traditionally divided into four categories based on the wavelength. Near Infrared:- 750-1500 nanometers. Middle Infrared:- 1500-6000 nanometers. Far Infrared:- 6000-40,000 nanometers. Far far Infrared:- 40.000-1milimeter. Infrared , a direct or incoming network connection to a remote access server using an infrared port. Infrared technology is the use of the lesser frequency of light for electronic purposes. It needs the hindsight of touch or nearness. Infrared technology is used mainly in television remotes and low budget mobiles. They work through a processor and sensor and need both to be in plain sight of each other. If that is not done, the technology won’t work. It works even on reflection and mirrors or water provide genuine reflectors for infrared technology. The general distance between the transmitter and receptor needs to be less than 10 meters. BLUETOOTH Bluetooth: Technology protocol developed to wireless connect electronic devices such as wireless phones personal digital assistants(PDAs) and computers. Devices equipped with bluetooth chips can exchange information within about a 30 foot range via radio waves in the 2.45 GHz spectrum. Bluetooth was developed by the Bluetooth special Internet Group, a consortium of telecommunication, computing, consumer, electronics, and related industry group. A specification for radio links between mobile PCs, mobile phones and other portable devices. These links are small-form factor, low cost and short range. Bluetooth is a device using radio frequency. It works on signals and will wok even if barricaded. If the transmitter and receptor are within 30 feet, there can be an inter-passage of important details like videos or songs. Now, even Bluetooth watches have come into fold. It is quite easy to infer that Bluetooth has a decisive edge over Infrared technology. MAIN DIFFERENCE::::: 1.Infrared supports only line off sight communication whereas in case of Bluetooth it is not required 2.Infrared has low data transmission rate compared to that of the Bluetooth 3.Infrared transmitter and receiver uses light source components whereas Bluetooth transmitter and receiver uses radio frequency components 4.Infrared is something like your remote you have to point the two devices sending as well as receiving. Whereas in Bluetooth that doesn't matter we can use the devices any where in the range. 5.infrared Signal will not pass through wall or object.while that of bluetooth,signals can.. 6.now days infrared has become old technology,while bluetooth is frequently used in new phones.

Basically, bluetooth and infrared are both wireless technology. Bluetooth does not need a direct line of connection like infrared. For exmple, to transfer information between two phones using infrared, the infrared red ports have to be lined up with nothing in between the ports blocking the connection. Bluetooth connection is usually about 33 feet with no "direct connection" needed

bluetooth used within 30metres of distance but infrared used when devices are kept together

Bluetooth is a form of microwave communication which could communicate within a circular Range, but Infrared connectivity is a form of optical transmission which can communicate within a linear line of sight Range

Easier terms, Infrared is like Connecting remote control to your television, while bluetooth is like making a wireless network with a router but smaller and only to your phone Well newer phones are taking out infrared considering bluetooth is much more usefull with a 10m radius distance. While infrared if your sending pictures to your buddy then you have to put the phones side by side with the sensors facing eachother. So think of bluetooth as a single popcorn in a big bowl, the popcorn is your phone and the empty area around the bowl is how far it can go. And infrared is like... kissing a person on the lips, to send a kiss from your lips must come contact with other lips

Blue tooth is only mobile purpose but infrared is always to that any network to use

Both bluetooth and infrared are wireless technology in cell phones, Infrared is like Connecting remote control to your television, while bluetooth is like making a wireless network with a router but smaller and only to your phone. Infrared technology is what most TV remotes use, Bluetooth, on the other hand, uses a radio frequency, which allows transmission through walls and other objects

bluetooth has more range than infrared for working

Bluetooth uses RF (radio frequency) to broadcast the information, like cordless phones. Infrared uses light like a TV remote control. RF will pass through opaque objects like walls. Infrared, being light, must be seen by the item receiving the signal. So, there must not be anything between the sender and the receiver that blocks the light, or the light must be bounced off of something to get around an object in-between sender and receiver

Bluetooth connection can be established wireless with both the devices are far from each other where as in IRDA connection both the devices IDRA sensors needs to be in front of each other. Infrared is almost like a wired connection as it doesnot provide mobility

bluetooth is advanced to infrared. If you want to transfer data by using infrared you have to keep both the mobiles very close to eanch other by using bluetooth no need to keep like this

Bluetooth connected in 100 mtr distance but infrared have not. bluetooth have fast processing and infrared have not.

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.

Also, this means that the range of bluetooth can be greater than that of infrared. Read more: http://wiki.answers.com/Q/What_is_the_difference_between_bluetooth_and_infrared#ixzz1KiQUtM70
