Bluetooth Grounding • 2.4 GHz Application • Standard Platform by SIG • Class 1: 100M Class 2: 10M Class 3: 1M • Version: V1.2, 2.0, 2.0+EDR,3.0,4.0+HS • Low Power consumption • Profiles – HSP / HFP / A2DP / AVRCP / OPP / FTP & etc.
History of Bluetooth Bluetooth 1.0A (July 26, 1999) Bluetooth 1.0B (December 1, 1999) • Suffered from a number of interoperability and anonymityproblems. Bluetooth 1.1 (Feb 22, 2001) • Improved robustness. • Support for non-encrypted channels. • Received Signal Strength Indicator (RSSI).
Bluetooth 1.2 (Nov 5, 2003) • Adaptive Frequency-Hopping (AFH) to avoid interference • Add Fast Connections (typical = 100 ms) • Extended Synchronous Connections Oriented links • (eSCO) improved voice quality of audio connections. • 50 million Bluetooth chips shipped
Bluetooth 2.0 + EDR (Nov 4, 2004) • Enhanced Data Rates (EDR) bringing user data transfer • rates of up to 2.1 Mbit/s. • Reduced power consumption. • 2006 - 500 million Bluetooth chips shipped Bluetooth 2.1 + EDR (July 26, 2007) • Specification improvements and feature enhancements • Extended Inquiry Response • Secure Simple Pairing • 2008 – 1 billion Bluetooth chips shipped
Bluetooth 3.0 + HS (April 21, 2009) • Use of 802.11 b/g radio for High Speed data transferusing Bluetooth profiles • Data rate 24Mbps for data; • Approximately 8 times faster than EDR if no SCO connection • active • 12Mbps with SCO (for voice); • Approximately 4 times faster than EDR if SCO connectionactive • Enhanced Power Control Bluetooth 4.0 (Dec 17, 2009) • Bluetooth Low Energy controller • Bluetooth 4.0 (Jun 30, 2010) • Bluetooth Low Energy Host
