Introduction: 

Introduction Bluetooth is an always-on, short-range radio hookup that reside on a microchip. It is initially developed by Swedish mobile phone maker Ericsson in 1994 as a way to let laptop computers make calls over a mobile phone. Industry observers expect Bluetooth to be installed in billions of device by 2005. The Bluetooth standards are published by an industry consortium known as the Bluetooth SIG (special interest group). Eliminate cables linking Computers to printers, keyboareds, and The mouse. 8 April, 2011 3

Introduction: 

Introduction Hook up Mp3 players wirelessly to other machines to download music. Set up home networks that a couch potato can remotely monitor air conditioning, the oven, and children’s Internet surfing. Call home from a remote location to turn to turn appliances on and off, set the alarm, and monitor activity. 8 April, 2011 4

What is Bluetooth?: 

8 April, 2011 5 What is Bluetooth? “Bluetooth is a short –range wireless technology is an open specification for a low-cost, low-power, short-range radio technology for ad-hoc wireless communication of voice and data anywhere in the world.” One of the first modules (Ericsson) A recent module

Why Bluetooth:

Computer Requirments: 

Computer Requirments A Typical Bluetooth USB Dongle. A Bluetooth USB dongle with a 100m rang the MacBook pro , shown, also hasa built in Bluetooth adaptor. 8 April, 2011 7

Headset Profile: 

8 April, 2011 8 Headset Profile Profile provides: Both devices must provide capability to initiate connection & accept/terminate calls. Volume can be controlled from either device. Audio gateway can notify headset of an incoming call.

Ultimate Headset: 

8 April, 2011 9 Ultimate Headset

Cordless Computer: 

8 April, 2011 10 Cordless Computer

Typical Bluetooth Scenario: 

8 April, 2011 11 Typical Bluetooth Scenario Bluetooth will support wireless point-to-point and point-to-multipoint (broadcast) between devices in a piconet. Point to Point Link Master - slave relationship Bluetooth devices can function as masters or slaves Piconet It is the network formed by a Master and one or more slaves (max 7) Each piconet is defined by a different hopping channel to which users synchronize to Each piconet has max capacity (1 Mbps) m s s s s m

Advantages of Bluetooth: 

Advantages of Bluetooth Bluetooth device are wireless. Bluetooth is automatic. Low energy consumption. Share voice and Data. Bluetooth Technology is inexpansive. Standardized Protocol. Instant personal area network. Bluetooth does not need to be set up. It is always on, running in the background. Bluetooth device can penetrate through solids. 8 April, 2011 12

Disadvantages of Bluetooth: 

Disadvantages of Bluetooth When there is number of Mobile device in the same room, and possibly attempting the same operation, it encounters problem in discovering the intended recipient device. Bluetooth device must perform a discover operation that will likely find many other device in the same room . At this point the user must choose the proposed recipient, whine will require special information. Bluetooth has a data rate of 1mbsp, hence transfer of data though this a very slow process. Another Disadvantages is of Security. The Greater range and radio frequency of Bluetooth make it much more open to interception and attack. 8 April, 2011 13

Future of Bluetooth: 

8 April, 2011 14 Future of Bluetooth Success of Bluetooth depends on how well it is integrated into consumer products Consumers are more interested in applications than the technology Bluetooth must be successfully integrated into consumer products Must provide benefits for consumer Must not destroy current product benefits Key Success Factors Interoperability Mass Production at Low Cost Ease of Use End User Experience

Security: 

8 April, 2011 15 Security Security Measure Link Level Encryption & Authentication. Personal Identification Numbers (PIN) for device access. Long encryption keys are used (128 bit keys). These keys are not transmitted over wireless. Other parameters are transmitted over wireless which in combination with certain information known to the device, can generate the keys. Further encryption can be done at the application layer.
