  1. Short range wireless – where we are, what's on the horizon, and what's in store for the future a Bluetooth™ Update …the current landscape and what the future holds for Bluetooth Ian Gifford IEEE Chair, 802.15.1 giffordi@ieee.org September 11, 2001 Boston, Wireless Speaker Series Kick off

  2. Summary • Bluetooth is a global, RF-based (ISM band: 2.4 GHz), short-range, connectivity solution for portable, personal devices • it is not just a radio, it is an end-to-end solution • The Bluetooth spec comprises • a HW & SW protocol specification • usage case scenario profiles and interoperability requirements • IEEE 802.15.1 is working on standardizing the PHY and MAC layers in Bluetooth • More Info: • http://www.bluetooth.org • http://ieee802.org/15/pub/TG1.html Ian Gifford <giffordi@ieee.org>

  3. Bluetooth SIG Goal & Solution • Goal: Develop interoperable products • SIG Solutions • Create a license free specification for its members for developing and manufacturing products and software using the Bluetooth specification. • License free Intellectually Property (IP) policy for SIG members under conditions defined by membership agreement. • No required fees or dues for membership • Membership agreement contain Confidentiality rule Ian Gifford <giffordi@ieee.org>

  8. Bluetooth RF Specifications Specified for low cost, single chip implementation • Noise floor margin for substrate noise and low current LNA • Linearity set by near-far problem • In-band image allows low-cost low IF • VCO phase noise enables integrated VCO • TX-RX turn around time enables single synthesizer • 2.4 ISM band chosen for global use and process capabilities Sensitivity traded for low cost integration capability Ian Gifford <giffordi@ieee.org>

  9. S M P sb S S P P sb M S The Bluetooth network topology • Radio designation • Connected radios can be master or slave • Radios are symmetric (same radio can be master or slave) • Piconet • Master can connect to 7 simultaneous or 200+ inactive (parked) slaves per piconet • Each piconet has maximum capacity (1 MSps) • Unique hopping pattern/ID • Scatternet • Piconets can coexist in time and space Ian Gifford <giffordi@ieee.org>

  10. Functional Overview • Standby • Waiting to join a piconet • Inquire • Ask about radios to connect to • Page • Connect to a specific radio • Connected • Actively on a piconet (master or slave) • Park/Hold • Low Power connected states Ian Gifford <giffordi@ieee.org>

  11. D A E B C or The Piconet • All devices in a piconet hop together • To form a piconet: master gives slaves its clock and device ID • Hopping pattern determined by device ID(48-bit) • Phase in hopping pattern determined by Clock • Non-piconet devices are in standby • Piconet Addressing • Active Member Address (AMA, 3-bits) • Parked Member Address (PMA, 8-bits) Ian Gifford <giffordi@ieee.org>

  13. Bluetooth SIG Document Process • Designed to promote interoperability • Three type of documents • Protocols • Profiles • Test Documents • Document are confidential until adopted • Intellectually Property license trigged by the adoption date • SIG unlikely to release documents until adopted Source: Kris Fleming 20Mar01 [Bluetooth-BOF-at-50th-IETF-PAN-Talk.ppt] Ian Gifford <giffordi@ieee.org>
