presentation about the core architecture of blueooth version 3 or high speed

1. Bluetooth V 3.0+HS

3. Main Features of Bluetooth v 3.0+HS

4. Bluetooth V 3.O+HS Features Bluetooth 3.0 is the new Bluetooth wireless standard currently in development by the Bluetooth SIG and Wi-Media Alliance. The new standard is reportedly up to 160 times as fast as Bluetooth 2.1, and builds upon the previous standards.

5. Bluetooth V 3.O+HS Features It is fast: Bluetooth 3.0 will reportedly transfer files at rates of 480 megabits (60 Megabytes) per second in close proximity, and 100 megabits (12.5 Megabytes) per second at 10 meters. High bandwidth mitigates interference : Bluetooth 3.0 will operate in the 6-9 GHz range rather than the current 2.4 GHz range, eliminating the concern of interference from wireless networks and other devices that use the 2.4 GHz range. Backwards compatibility Best of all, Bluetooth 3.0 will be backwards-compatible, so all of your old devices will be able to communicate with the new ones and vice versa. New devices will feature a 2.4 GHz Bluetooth radio on the same radio chip, or its own separate chip.

6. Inside the Bluetooth Specification

7. Core system architecture Host Host Host BR/EDR Controller BR/EDR Controller AMP Controller BR/EDR Controller AMP Controller AMP Controller The Bluetooth core system consists of a Host and one or more Controllers. A computing device, peripheral, cellular telephone, access point to PSTN network or LAN, etc.

8. Core system architecture A host is defined as all of the layers below the profiles and above the Host Controller Interface (HCI). A Controller is defined as all of the layers below HCI. Two types of Controllers are defined in this version of the Core Specification: • A Basic Rate / Enhanced Data Rate(BR/EDR) Controller including the Radio, Baseband, Link Manager and optionally HCI. • An Alternate MAC/PHY (AMP) Controller including the AMP PAL (Protocol Adaptation Layer), AMP MAC, Protocol Adaptation Layer (PAL), and optionally HCI.

24. COMMUNICATION TOPOLOGY PICONET TOPOLOGY:

27. Operation Procedures & modes Role switch procedure : The role switch procedure is a method for swapping the roles of two devices connected in a piconet. Enhanced Data Rate: is a method of extending the capacity and types of Bluetooth packets for the purposes of increasing the maximum throughput, providing better support for multiple connections, and lowering power consumption, while the remainder of the architecture is unchanged.

29. CHANGES FROM V2.1 TO V3.0 + HS Several new features are introduced in Bluetooth Core Specification v3.0 + HS. The major areas of improvement are: • AMP Manager Protocol (A2MP) • Enhancements to L2CAP including • Enhanced Retransmission Mode and Streaming Mode • Improvements to the L2CAP state machine for AMP channels • Fixed channel support • Enhancements to HCI for AMP • Enhancements to Security for AMP • 802.11 Protocol Adaptation Layer • Enhanced Power Control • Unicast Connectionless Data • HCI Read Encryption Key Size command • Generic Test Methodology for AMP • Enhanced USB and SDIO HCI Transports
