  1. Bluetooth Technology Created by Matt Romita and Mohammed Hasham for BCS 312 and used in BCS 555

  2. What Is Bluetooth? • Designed to be used to connect both mobile devices and peripherals that currently require a wire • Simplifying communications between: • - devices and the internet • - data synchronization • “USB without wires” • Short range wireless radio technology • - operate range of 10 meters

  3. Advantages (+) • Wireless (No Cables) • No Setup Needed • Low Power Consumption (1 Milliwat) • Industry Wide Support

  4. Disadvantages (-) • Short range (10 meters) • Small throughput rates • - Data Rate 1.0 Mbps • Mostly for personal use (PANs) • Fairly Expensive

  5. How Does It Work? • Bluetooth is a standard for tiny, radio frequency chips that can be plugged into your devices • These chips were designed to take all of the information that your wires normally send, and transmit it at a special frequency to something called a receiver Bluetooth chip. • The information is then transmitted to your device

  6. Bluetooth Specifications • Each channel is divided into time slots 625 microseconds long • Packets can be up to five time slots wide • Data in a packet can be up to 2,745 bits in length

  7. Bluetooth Frequency • Has been set aside by the ISM for exclusive use of Bluetooth wireless products • Communicates on the 2.45 GHz frequency

  8. Avoiding Interference : Hopping • Bluetooth uses a technique called spread-spectrum frequency hopping. • In this technique, a device will use 79 individual, randomly chosen frequencies within a designated range • Transmitters change frequency 1600 times a second

  9. What’s With the Name? • King Harald Bluetooth (A.D. 940 to 985) • 10th century Viking king in Denmark • Credited for uniting the country and established Christianity • Viking states included Norway & Sweden, which is the connection to Ericsson (creator of bluetooth)

  10. Who Started Bluetooth? Ericsson Mobile Communication • Bluetooth Special Interest Group (SIG) • -5 founding members • -Ericsson, Nokia, IBM, Intel & Toshiba • Promoter’s Group • - 3COM, Lucent, Microsoft, Motorola • Now over 1900 members

  11. Bluetooth Devices Bluetooth will soon be enabled in everything from: • Telephones • Headsets • Computers • Cameras • PDAs • Cars • Etc …

  12. Bluetooth Products 1 • Bluetooth-enabled PC Card

  13. Bluetooth Products 2 • Bluetooth-enabled PDA

  14. Bluetooth Products 3 • Bluetooth-enabled Cell Phone

  15. Bluetooth Products 4 • Bluetooth-enabled Head Set

  16. Target Markets • Telecommunications • Networking • Computing • Industrial • Medical • Automotive • Vertical Markets (Hotels,Airports,Healthcare)

  17. Modding Bluetooth Dept.: Void Your WarrantyTech: Bluetooth antennaBase Cost: $85Time: 30 minutes Detach the stock antenna from a Linksys USBBT100 Class 1 USB Bluetooth adapter ($70; linksys.com) and replace it with a larger HyperGain RE05U 2.4GHz antenna ($15; hyperlinktech. com) With that simple mod, you can make a Bluetooth connection up to a about 5,000 feet farther than most. Bandwidth isn’t increased, but now you can connect your Bluetooth devices from anywhere in the house or yard. [See bluedriving. com for more Bluetooth projects.]

  18. Bluetooth’s Future • The future of this technology becoming a standard is likely • With a strong industry pushing behind it, success is inevitable. • Bluetooth will soon be known as Bluetooth 1.2. as they are trying to develop the product to better fulfill the needs of consumers • Often, with new technology, early changes mean reconstruction. Not With Bluetooth, instead, there will be an improvement to the existing standard.
