It uses radio frequency for a short range around 10 meters and can be extended to 100 meters by increasing the power. Any two devices that follow the standard can communicate and exchange data between each other without the need of any connection to be made between them. Can instantly form a network with each other as soon as they are switched on. What is Bluetooth? Slide 2: How Bluetooth Technology Works Slide 3: Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user. The technology uses modifications of existing wireless LAN techniques. This technology achieves its goal by embedding tiny, inexpensive, short-range transceivers into the electronic devices that are available today. The radio operates on the globally-available unlicensed radio band, 2.45 GHz and supports data speeds of up to 721 Kbps, as well as three voice channels. Continues………. Slide 4: Continues………. The bluetooth modules can be either built into electronic devices or used as an adaptor. They can be built in as a PC card or externally attached via the USB port. Each device has a unique 48-bit address from the IEEE 802 standard. Connections can be point-to-point or multipoint. Bluetooth devices are protected from radio interference by changing their frequencies arbitrarily upto a maximum of 1600 times a second, using a technique known as Frequency Hopping. Bluetooth guarantees security at the bit level. Authentication is controlled by the user by using a 128 bit key. Slide 5: Wireless networking between PCs in a confined space and where little bandwidth is required. Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer. Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX. Replacement of traditional wired serial communications in test equipment, GPS receivers, medical equipment, bar code scanners, and traffic control devices. List of Application Slide 6: Continues………. For low bandwidth applications where higher [USB] bandwidth is not required and cable-free connection desired. Sending small advertisements from Bluetooth-enabled advertising hoardings to other, discoverable, Bluetooth devices. Wireless bridge between two Industrial Ethernet (e.g., PROFINET) networks. For controls where infrared was traditionally used. Slide 7: Bluetooth 1.0 and 1.0B :- Versions 1.0 and 1.0B also included mandatory Bluetooth hardware device address transmission in the Connecting process, which was a major setback for certain services planned for use in Bluetooth environments. Bluetooth 1.1 :- Ratified as IEEE Standard 802.15.1-2002. Many errors found in the 1.0B specifications were fixed. Added support for non-encrypted channels. Received Signal Strength Indicator (RSSI). Bluetooth 1.2 :- Faster Connection and Discovery. Higher transmission speeds in practice, up to 721 kbit/s, than in 1.1. Ratified as IEEE Standard 802.15.1-2005. Introduced Flow Control and Retransmission Modes for L2CAP. Versions of Bluetooth Slide 8: Bluetooth 2.0 :- Released on November 10, 2004. It is backward compatible with the previous version 1.2. Lower power consumption through a reduced duty cycle. Bluetooth 2.1 :- Was adopted by the Bluetooth SIG on July 26, 2007.It is fully backward compatible with 1.2. Bluetooth 3.0 :- The 3.0 specification was adopted by the Bluetooth SIG on April 21, 2009. Its main new feature is AMP (Alternate MAC/PHY), the addition of 802.11 as a high speed transport. AMP :- Enables the use of alternative MAC and PHYs for transporting Bluetooth profile data.It means, when lots of data needs to be sent, the high speed alternate MAC PHY (802.11, typically associated with Wi-Fi) will be used to transport the data. Continues……… Slide 9: A personal computer must have a Bluetooth adapter in order to communicate with other Bluetooth devices Some desktop computers and most recent laptops come with a built-in Bluetooth adapter, others will require an external one in the form of a dongle. Bluetooth allows multiple devices to communicate with a computer over a single adapter. Computer Requirements Slide 10: Apple has supported Bluetooth since Mac OS X v10.2 which was released in 2002. For Microsoft platforms, Windows XP Service Pack 2 and later releases have native support for Bluetooth. Linux has two popular Bluetooth stacks, BlueZ and Affix. The BlueZ[stack is included with most Linux kernels. The Affix stack was developed by Nokia. Operating System Requirements Slide 11: A mobile phone that is Bluetooth enabled is able to pair with many devices. To ensure the broadest support of feature functionality together with legacy device support, the Open Mobile Terminal Platform (OMTP) forum has recently published a recommendations paper, entitled "Bluetooth Local Connectivity". Mobile Phone Requirements Slide 12: LMP (Link Management Protocol) :- Used for control of the radio link between two devices. Implemented on the controller. L2CAP (Logical Link Control & Adaptation Protocol) :- Used to multiplex multiple logical connections between two devices using different higher level protocols. Provides segmentation and reassembly of on-air packets. SDP (Service Discovery Protocol) :- Used to allow devices to discover what services each other support, and what parameters to use to connect to them. Bluetooth Protocols Slide 13: HCI (Host/Controller Interface) :- This standard allows the host stack or controller IC to be swapped with minimal adaptation. The most commonly used HCI are USB (in PCs) and UART (in mobile phones and PDAs). RFCOMM (Cable replacement protocol) :- It is the cable replacement protocol used to create a virtual serial data stream. RFCOMM provides for binary data transport and emulates EIA-232 (formerly RS-232) control signals over the Bluetooth baseband layer. a simple reliable data stream to the user, similar to TCP. Continues…………. Slide 14: Point-to-Point Protocol (PPP) :- Internet standard protocol for transporting IP datagrams over a point-to-point link TCP/IP/UDP :- Foundation Protocols for TCP/IP protocol suite Object Exchange Protocol (OBEX) :- Session-layer protocol for the exchange of objects, providing a model for object and operation representation Wireless Application Protocol (WAP) :- WAP is an open standard to provide mobile users access to telephony and information services. Adopted Protocols Slide 15: Any Bluetooth device will transmit the following information on demand: Device name. Device class. List of services. Technical information, for example, device features, manufacturer, Bluetooth specification used, clock offset. Setting up Connections Slide 16: Pairs of devices may establish a relationship by creating a shared secret known as a link key, this process is known as pairing. If a link key is stored by both devices they are said to be bonded. Bluetooth services generally require either encryption or authentication, as such require pairing before they allow a remote device to use the given service. Pairing Slide 17: Legacy pairing: This is the only method available before Bluetooth 2.1. Each device must enter a PIN code, pairing is only successful if both devices enter the same PIN code. Secure Simple Pairing: This is required by Bluetooth 2.1. A Bluetooth 2.1 device may only use legacy pairing to interoperate with a 2.0 or earlier device. Secure Simple Pairing uses a form of public key cryptography. Pairing Mechanisms Slide 18: In most cases, it does not require a user to generate a passkey. For use-cases not requiring MITM, user interaction has been eliminated. For numeric comparison, MITM protection can be achieved with a simple equality comparison by the user. Using OOB with NFC will enable pairing when devices simply get close, rather than requiring a lengthy discovery process. SSP is considered simple for the following reasons Slide 19: Broadcast Channel :- Enables Bluetooth information points. This will drive the adoption of Bluetooth into mobile phones, and enable advertising models based around users pulling information from the information points, and not based around the object push model that is used in a limited way today. Topology Management :- Enables the automatic configuration of the piconet topologies especially in scatternet situations that are becoming more common today. This should all be invisible to users of the technology, while also making the technology "just work.“ QoS Improvements :-Enable audio and video data to be transmitted at a higher quality, especially when best effort traffic is being transmitted in the same piconet. Future Slide 20: Plug n Play Robustness Low complexity Low power: battery powered Low cost: about $5 Fast acknowledgement Fast frequency hopping scheme Shorter packets Conclusion You do not have the permission to view this presentation.
