The main tasks for the Bluetooth SIG. Bluetooth Technology Over the Years Bluetooth was officially introduced in 1998 The first Bluetooth core specification version 1.1 was introduced in 1998 In 2003 Bluetooth core specification version 1.2 was adopted by the Bluetooth SIG In 2004,Bluetooth version 2.0 + EDR(Enhanced data rate) was introduced In 2009,Bluetooth SIG adopted core specification version 3.0Product Association: Product Association Phone : Music, data. Laptop : Transfer data ,connect to various gadgets. Printer : Wireless print data, photos. Camera : Send images to printer, mobile, pc.Product Association (Cont’d): Product Association (Cont’d) TV : Unique slide show. Headset : Keep your hands free. Photo Viewer : Without memory cards. Gaming : Wireless controllers.Bluetooth: Advantages: Bluetooth: Advantages Bluetooth Devices are Wireless Bluetooth Technology is Inexpensive Multiple Product Association. Low Energy Consumption Bluetooth is Automatic.Bluetooth: Disadvantages: Bluetooth: Disadvantages One device at a Time Low Data Transfer Rate Security Threats Bluejacking Bluesnarfing BluebuggingProtocol: Protocol Detecting the presence of other devices Establishing communications guidelines between two devices (AKA: Handshaking) Determining the various connection characteristics How to format a message How to start and end a message What to do with corrupted or incorrectly formatted messages How to recognize unexpected connection loss, and what to do next Ending the connection or “conversation”Bluetooth: How does it work?: Bluetooth: How does it work? Frequency – 2.4Ghz Standard protocol PAN / Piconet – Master & Slave Profile Hopping - AFHComparison with Other Technologies: Comparison with Other Technologies Wi-Fi A Wi-Fi enabled device can connect to the Internet when within range of a wireless network connected to the Internet Bluetooth technology costs a third of Wi-Fi to implement Bluetooth technology uses a fifth of the power of Wi-Fi Under Wi-Fi, different certified versions have varying data transfer rates and work under different frequenciesComparison with Other Technologies (Cont’d): Comparison with Other Technologies (Cont’d) InfraRed (IrDA) IrDA is used to provide wireless connectivity for devices that would normally use cables to connect Point-to-point, narrow angle (30° cone), ad-hoc data transmission standard designed to operate over a distance of 0 to 1 meter and at speeds of 9600 bps to 16 Mbps Not able to penetrate solid objects and has limited data exchange applications compared to Bluetooth IrDA is mainly used in payment systems, in remote control scenarios or when synchronizing two PDAs with each otherBluetooth: The Future : Bluetooth: The Future It meets a basic need of connectivity in close proximity hence high demand expected to grow Since the formation of the original group, more than 1800 manufacturers worldwide have joined the initiative worldwide Adoption of smart phones and handheld devices, Bluetooth will have tremendous effects on everyday life Combining with other technologies e.g. 4G and 5GPowerPoint Presentation: Thank You!
