Application requirements1
Application Requirements Area Networks (WPANs)

Overall System

  • System Operation: Half Duplex, symmetrical, isochronous operation that supports real-time multimedia

  • Multi-mode Protocol Support:

    • 20 Mbps operation in High-rate mode,

    • BlueTooth1 compliant operation in

    1 Mbps mode

  • Operating Frequencies: 2.4 GHz and 5 GHz ISM bands

    (Unlicensed operation)

  • RF Range / Coverage: 10 to 15 meters in the home environment


Application requirements2
Application Requirements Area Networks (WPANs)

Overall System

  • Number of channels: 7 minimum

  • Security: System level compatibility with WAP cellular protocols, internet E-Commerce

    protocols, etc

  • Cost Targets: $10 U.S. BOM cost in 2001 for high volume production

  • Low Power: Suitable for use in portable, battery operated

    equipment

  • Complexity Use proven, existing technology consistent and Development with the performance and price goals of the Risk: Personal Area Networking space


Application requirements3
Application Requirements Area Networks (WPANs)

Physical Layer

  • Channel Data Rate: 20 Mbits / sec min.

  • Number of channels: 7 minimum (20Mbps ea.)

  • Channel Noise Immunity

    • Error Tolerance: FEC capable of correcting a 0.1% BER

    • Delay Spread Tolerance: 100 Nanoseconds

  • Security: Assurance of privacy and prevention

    of theft-of-service

  • Co-existence / compatibility: Compatibility with other protocols

    operating in the same band

  • Operating frequency / 2.4 GHz and 5 GHz ISM bands

    licensing requirements: (Unlicensed operation)


Application requirements4
Application Requirements Area Networks (WPANs)

MAC Layer

  • QOS Support for multiple ( 3 or more) streams of real-time video plus three voice channels and an internet traffic channel

    Support for up six high fidelity audio channels plus one real-time video channel

  • Security Upper level support for implementation of WAP cellular protocols, internet

    E-Commerce protocols, etc

  • Complexity and Complexity consistent with the low cost Cost and power drain goals of the Personal Area Networking space

  • Low Development risk If possible, use an existing and proven MAC layer to reduce risk and shorten the time to market


Other considerations
Other Considerations Area Networks (WPANs)

  • We need to avoid competing standards in the same operating / performance space
