Name taken from the 10th century King Herald Bluetooth
King Bluetooth attached all Scandinavian people when they were torn apart due to wars and feuding lans.
Bluetooth was first developed in Scandinvia
It is also able to unite differing industries
E.g. cell phone, computer, automotive markets
It was officially introduced in 1998
Basic purpose was to be a wire replacement technology
In 2003 the bluetooth 2.1 intorduced
In 2004 bluetooth 2.0+EDR introduced
Devices using BT+EDR entered in 2005
Bluetooth uses wireless protocol for the devices
It forces devices to agree on When bits are sent How many will be sent at a time How devices can sure message received
It is short range wireless ,secure and international std. technology
It provides communication between bluetooth enabled device.
It uses radio waves that operates @2.4GHz
The master bluetooth device can communicate with seven other bluetooth enabled device.
Bluetooth 3.0 provides high speed connections
It also supports VOIP technology
Typical bluetooth device consist of RS trenceiver, protocol stack and baseband
It was able to connect computer with printer and other nodes
Bluetooth provides speed of 1-2 Mbps
It can be used internally as well as externally
Bluetooth enabled devices can change their frequency rapidly so they can be saved from external interference
For security it uses pin code and 128 encryption
It uses AFH facility to control interference
AFH works within the spectrum to take advantage of the available frequency
Range of Bluetooth• Class 3 radios – have a range of up to 1 meter or 3
feet• Class 2 radios – most commonly found in mobile
devices – have a range of 10 meters or 33 feet• Class 1 radios – used primarily in industrial use
cases – have a range of 100 meters or 300 feet
• Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec
Logical Link Control andAdaptation protocol (L2CAP)
Link Manager (LM) protocol

Advantage• It is wireless technology
• It is safe and convenient
• Made networking portable
• It makes life easier
DISADVANTAGE1. Battery use2. Bluetooth Internet speed is slow
Infrared technologyIt was established in 1993Purpose was to provide wireless connectivityIt allows point to point user access modelFrequency id THzCommunication is possible due to tansceiver
IR can be used over longer interconnections and has an applicability to local area networks (LANs)
Maximum distance is 1mileMaximum bandwidth is 16 MbpsIt is secure networking applicationIn future it will be implemented in BANK,ATM,
Credit Cards etc.
It is more reliableSome manufacturer provides IrDA port that allows
wireless keyboard to communicate with PCInfrared signals defined by IrDA transmit through
line of sightStandard originally data transmission rate is
75Kbps for a distance up to 8 meterNow it is 4Mbps.
