  1. A Survey of Bluetooth Applications By: Ken Iverson, Nasr Sattar, Derek Simpson, & Tim Wilson

  2. Overview • Low-cost, short-range wireless standard. • Released in 1999. • Bluetooth SIG. • Operates at 2.4GHz in the ISM Band. • Maximum Speed: 1Mbps

  3. Potential Applications • Personal Area Networks (PANs) • Cellular Infrastructure Improvement • Wireless Audio • Internet Access for Mobile Devices • Simple Cable Replacement

  4. Technical Specifications • Positive Frequency Deviation = 1 • Negative Frequency Deviation = 0 • Master-Slave Architecture (Frequency Hopping) • Antenna Types • Baseband • Link Control Layer • Link Manager

  5. Wireless Access Protocol(WAP)

  6. WAP • Wireless Application Protocol (WAP) is an open, global specification that empowers mobile users with wireless devices to easily access and interact with information and services instantly.

  7. WAP cont. • WAP is applicable to handheld digital wireless devices such as mobile phones, pagers, two-way radios, smart phones, and communicators. • WAP has client/server architecture, allowing mobile devices to use micro browsers. Micro browsers are specialty browsers, able to fit on smaller screens and use lesser memory.

  8. WAP cont. • HTML is replaced by WML. • The mobile access usage will increase drastically as there are many more mobile users than desktop PC users. • Current website providers have WAP pages, able to be viewed on mobile devices using micro browsers.

  9. WAP cont. • WAP uses several Internet protocols for mobile devices to access the Internet. It provides the following: • Wireless Application Environment • Wireless Session Protocol • Wireless Transport Protocol • Wireless Transport Layer Security

  10. WAP cont. • WAP uses various Internet protocols including PPP. The WAP layers are joined to Bluetooth by three Internet protocols. • Bluetooth has a RFCOMM serial port emulation layer through which Bluetooth datagrams are sent from the three WAP Internet protocol layers.

  11. Personal Area Networks • Fast-Growing Technology • Piconets • Point to Point vs. Point to Multipoint Connections • Scatternets • Scatternet Architectures • Bluetooth Network Encapsulation Protocol (BNEP)

  12. Network Access Points • NAP Device • Access to Wired Networks • Connection Process • Packet Filter Database

  13. Group Ad-Hoc Networks • Local Access Only • GN Compatibility • Connection Process • Termination of GN Connections

  14. Bluetooth Audio • Quality • GSM data format – same as cellular phone • Tradeoffs • Quality vs. Robustness • Quality • SCO link • ACL channel

  15. Bluetooth Audio cont… • Coding techniques • Log PCM • CVSD • Applications • Automobiles • Headsets • Stereo systems

  16. Bluetooth and Cellular Infrastructure • Bluetooth in the GSM markets • Mobile Cellular Internet • Bluetooth and Cell Phone interference

  17. Telephony Control • TCS-BIN layer • Controls voice and data • Binary encoding for packet-based telephony control • Exchange call signaling information

  18. Bluetooth Usage Models • Ultimate Headset • Wireless Headset • Communication with other devices • Voice recognition • Three-In-One Phone • One phone for office, home, and mobile • Reduce cellular air time

  19. Exam Question This protocol is an open, global specification that empowers mobile users with wireless devices to easily access and interact with information and services instantly. a. POP b. WAP c. LDAP d. BNEP Answer: B
