  1. UNDERSTANDING WIRELESS COMPLIANCE Stephen BergerTEM Consulting (512) 864-3365stephen.berger@ieee.org

  2. OVERVIEW Workshop topics will include a brief look at the new technologies and at possible regulatory rule changes to incorporate these technologies. With wireless playing an ever more key role, topics covered will reflect current issues and concerns regarding the compliance requirements. Speaker presentations will be followed by an open forum for questions at the end of the session.

  7. WIRELESS NETWORKING • BluetoothCable Replacement • 802.11 W-LANEnterprise Wireless Networking • HomeRFHome Networking

  8. Standards Activities • WG 802.15.2802.11 / Bluetooth Coexistence • EMC SDCom (Society Standards Development Committee)Study of general problem of band crowding Review appropriateness of current standards Ultrawideband Clock Dithering

  9. Bluetooth / 802.11 Coexistence • A serious problem that needs urgent solutions • Bluetooth voice applications are among the most important applications most sensitive to interference • Significant packet losses for Bluetooth links under 802.11b interference • Significant throughput drop for 802.11b network • Scenarios • Separated > 10 feet: minor problem • Problem when <10 feet distance • Also dependent on 802.11b duty cycle

  10. FCC PART 15 NPRM • Areas under consideration: • Retain Processing Gain Requirement • Reduce Number of Hops • Liberalize Spectrum Definitions • Craft Rules Similar to U-NII Rules • 915 MHz & 5.8 GHz bands may be included

  11. FCC PART 22 NPRM • Removing linkage with analog heritage.

  12. FCC PART 24 DEVELOPMENTS • 3G Technology • SAR Testing • TTY & Hearing Aid Compatibility • Other Technical Developments

  13. Wireless LAN Technologies • DSSS (DS) - Direct Sequence Spread Spectrum • FHSS (FH) - Frequency Hopping Spread Spectrum • UWB - Ultra Wideband • W-OFDM - Wideband Orthogonal Frequency Division Multiplexing
