  1. OVERVIEW NEXT GENERATION BLUETOOTH Basic Bluetooth was covered in class V2.1+EDR V3.0+HS V4.0 LE

  2. V2.1+EDR NEXT GENERATION BLUETOOTH • EDR (Enhanced Data Rate) • 2 New Modulation Coding Schemes • π/4 DQPSK – 2Mb/s • 8DPSK – 3Mb/s • Backward Compatibility with GFSK Source: Bluetooth® Enhanced, Data Rate (EDR): The Wireless Evolution, Agilent Technologies

  3. V3.0+HS NEXT GENERATION BLUETOOTH • New Terms • HS – High Speed (needs two devices with HS compatibility) • AMP – Alternate MAC/PHY Protocol • PAL – 802.11 Protocol Adaptation Layer • eL2CAP – Enhanced Logical Link Control and Adaptation Layer Protocol • UCD – Unicast Connectionless Data • EPC – Enhanced Power Control

  4. V3.0+HS NEXT GENERATION BLUETOOTH • Added Additional Controllers • BR/EDR (same as before) • AMP MAC/PHY • Allows 802.11 MAC/PHY access to achieves speeds >400Mbps • Management Entity - AMP Manager • Logical Link Changes (eL2CAP) required for +HS • Enhanced QoS • Enhanced Retransmission Mode • Flow Controls

  5. V3.0+HS • 802.11 PAL • Under Classic Bluetooth Protocols • Converts data from Bluetooth Domain to 802.11 Domain • Removes Bluetooth Header • Adds 802.11 Header • Completed in reverse as well • Works with or without L2CAP involvement NEXT GENERATION BLUETOOTH Source: Confidential BLUETOOTH HIGH SPEED TECHNOLOGY OVERVIEW, Broadcom Corporation, March 2, 2010 Source: http://www.palowireless.com/bluearticles/packets.asp Source: http://cecs.wright.edu/~pmateti/InternetSecurity/Lectures/WirelessHacks/Mateti-WirelessHacks_files/image002.jpg

  10. V3.0+HS NEXT GENERATION BLUETOOTH • UCD • Permits service data to be sent without establishing an explicit L2CAP channel. It is intended for use by applications that require low latency between user action and reconnection/transmission of data. This is only appropriate for small amounts of data • EPC • Updates the power control feature to remove the open loop power control, and also to clarify ambiguities in power control introduced by the new modulation schemes added for EDR. Enhanced power control removes the ambiguities by specifying the behavior that is expected. Additionally, a “go straight to maximum power” request has been introduced. This is expected to deal with the headset link loss issue typically observed when a user puts their phone into a pocket on the opposite side to the headset

  11. V4.0 LE NEXT GENERATION BLUETOOTH • Low Energy • Emerging Markets • Health Care • Fitness and Sports • Home Entertainment • Security
