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. Also, this means that the range of bluetooth can be greater than that of infrared.

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. Infrared: A computer or a computer peripheral such as printer, that can communicate by using infrared light. Having 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. Wireless file transfer between a computer and another computer or infrared devices using infrared light. Infrared uses electromagnetic radiation principle where wavelength of the emitting light corresponds to the frequency range of 1~400Thz.This is used for the communication purposes on different schemes like Near infrared (0.75 - 1.4um), Short infrared (1.4um - 3um), Mid infrared (3-8um), Long infrared (8 - 15um), Far infrared (15um - 1000um) Bluetooth uses radio frequency of 2.4Ghz(ISM Band) allocated for industrial science and medical applications which uses short distance communication service Infrared supports only line off sight communication whereas in case of Bluetooth it is not required Infrared has low data transmission rate compared to that of the Bluetooth Infrared transmitter and receiver uses light source components whereas Bluetooth transmitter and receiver uses radio frequency components

Answer: Infrared technology is what most TV remotes use. The distance an infrared signal can travel varies based on the strength of the remote, but is usually less than 50 feet for household electronics. In order for an infrared signal to be detected, there must be a direct line of sight between the transmitter (remote) and the receiver (TV). If there is a wall or large object between them, the signal will not pass through it. Bluetooth, on the other hand, uses a radio frequency, which allows transmission through walls and other objects. The standard range of a Class 3 Bluetooth device is about 30 ft., which makes it ideal for syncing PDAs with computers, using wireless cell phone headsets, and enabling handsfree cell phone use inside Bluetooth-enabled automobiles. Because Bluetooth technology is based on a standard 2.4 GHz frequency, different Bluetooth devices can typically communicate with each other, regardless of the manufacturer. Most infrared devices only work with proprietary equipment. While Bluetooth is well on its way to replacing infrared in many different areas, the technology is not meant to be used for wireless networking. Instead, Wi-Fi technology, which has a larger range and higher bandwidth than Bluetooth, is the standard that most wireless networking equipment uses.

Infrared is shorter wavelength technology that requires a straight line of sight between source and target. Bluetooth is longer wavelength technology which also has the advantage of a radial range of sight between source and target.

Range of infrared almost nil means if you are transferring data from infrared then you have to keep both these phones intouch from which you are transferring data but if you are doing same via bluetooth then you need not to keep your phone intouch just connect phones or create paired device and transfer data even the range of bluetooth is quite good especially in the latest mobiles coming in the market. that is different between bluetooth or infrared

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.

Infrared uses pulses of infrared rays to transmit data,bluetooth uses radiowaves of 2.4GHz frequency.The range of bluetooth is 2times larger than infrared and transmission speed is almost 10 times faster.Infrared requires direct line of sight to transmit data between devices.

infrared have no good frequency area but bluetooth have good frequency area like 10 miters 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 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.
