  11. Ubiquitous Internet Access

  12. Overview • Allows replacement of proprietary cables • Adhoc grouping (piconets) • Combination of circuit and packet switching • Avoids interference using freq hopping spread spectrum and FEC • Asynchronous connectionless - data channel (721/57.6kb/s) • Synchronous connection oriented - voice (432 kb/s)

  13. 1mb/s raw throughput (actual 728 kb/s) 2.402 GHz to 2.480 GHz, frequency hopping 79 hops displaced by 1 MHz RF output signal power of 1 mw (0 dBm, class 3) up to 100 mw 10 meters in low-power standard (100 in high) Time Division Duplex Radio Interface

  14. Link setup, authentication, link configuration protocols Discover remote LMs Naming/authentication Connection setup Link modes (voice/data) Bluetooth Link Manager

  15. Bluetooth Topology

  16. Each packet (0.635 s) in a different hop freq (1600 hops/s). Link establishment Standby/sniff/park/hold mode Link types Synchronous connection oriented (SCO) asynch connection-less (ACL) Error correction 1/3 FEC, 2/3 FEC and ARQ Bluetooth Baseband
