Transcript

  • 1. B luetooth T echnology Matt Romita & Mohammed Hasham
  • 2. What Is B luetooth?
    • Designed to be used to connect both mobile devices and peripherals that currently require a wire
    • Short range wireless radio technology
    • - operate range of 10 meters
    • Simplifying communications between:
    • - devices and the internet
    • - data synchronization
    • “ USB without wires”
  • 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
    • The information is then transmitted to your device
    • 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.
  • 6. B luetooth Specifications
    • Each channel is divided into time slots 625 microseconds long
    • Data in a packet can be up to 2,745 bits in length
    • Packets can be up to five time slots wide
  • 7. B luetooth 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 B luetooth?
    • Bluetooth Special Interest Group (SIG)
    • -5 founding members
    • -Ericsson, Nokia, IBM, Intel & Toshiba
    • Promoter’s Group
    • - 3COM, Lucent, Microsoft, Motorola
    • Now over 1900 members
    Ericsson Mobile Communication
  • 11. B luetooth Devices
    • Telephones
    • Headsets
    • Computers
    • Cameras
    • PDAs
    • Cars
    • Etc …
    Bluetooth will soon be enabled in everything from:
  • 12. B luetooth Products 1
    • Bluetooth-enabled PC Card
  • 13. B luetooth Products 2
    • Bluetooth-enabled PDA
  • 14. B luetooth Products 3
    • Bluetooth-enabled Cell Phone
  • 15. B luetooth Products 4
    • Bluetooth-enabled Head Set
  • 16. Target Markets
    • Telecommunications
    • Networking
    • Computing
    • Industrial
    • Medical
    • Automotive
    • Vertical Markets (Hotels,Airports,Healthcare)
  • 17. Modding B luetooth 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.] Dept. : Void Your Warranty Tech : Bluetooth antenna Base Cost : $85 Time : 30 minutes
  • 18. B luetooth’s Future
    • The future of this technology becoming a standard is likely
    • With a strong industry pushing behind it, success is inevitable.
    • Often, with new technology, early changes mean reconstruction. Not With Bluetooth, instead, there will be an improvement to the existing standard.
    • Bluetooth will soon be known as Bluetooth 1.2. as they are trying to develop the product to better fulfill the needs of consumers
