what is the difference between bluetooth & infrared?

Answer 1

i believe infrared needs to be aligned, but bluetooth just needs to be in proximity of source. if that makes any sence at all.

Answer 2

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 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 3

Bluetooth is a radio signal, and non-directional. Infrared is a light-wave communication and is limited to line of sight. Even a piece of paper between the transmitter and receiver will disrupt communications.
Bluetooth also has a few different specs which allow for range from a few feet to a few tens of feet. Bluetooth is also quite a bit faster than infrared.
Bluetooth is definitely more versatile.

Answer 4

Bluetooth is a technologies offering instantaneous very own section networks (WPANs) for small contraptions as cellular telephones or PDAs. It operates on the unlicensed 2.4-GHz commercial-medical-medical (ISM) band, and has surely been prevalent by capacity of Ericsson. The Bluetooth particular activity team (SIG) replaced into then based with its unique promoters being Nokia, IBM, Intel, and Toshiba. immediately, approximately 2000 individuals are counted, among them Agere, 3Com, Lucent, and Microsoft. The call "Bluetooth" replaced into chosen of the Denish King Harald Bluetooth. The complementary of Bluetooth is the Infrared device of the Infrared documents association (IrDA). throughout the time of the previous few months, it incredibly is been argued that Bluetooth has been created instead for Infrared. nevertheless, it incredibly is not extremely genuine: Bluetooth has been invented as an enhancement of Infrared, extraordinarily in terms of low value, small quantity, low capacity, and the accomplishment of Infrared's barriers, such using fact the its unidirectional connections, the connectivity selection of in basic terms meter or its disadvantage to point-to-factor connections. in spite of the reality that Bluetooth has rather coped with those constraints, e.g. by capacity of omnidirectional connections, the connectivity selection of as much as ten meters, or its capacity for factor-to-multipoint connections, the two technologies are extremely complementary. on a similar time as Bluetooth is quite applicative for networking, Infrared is extra acceptable for the direct connections, e.g. for changing company enjoying cards.

Answer 5

bluetooth is powerful and infrared is less powerful. well the thing that seprates BLUETOOTH and INFRARED is the speed and connectivity
