UWB Activities

• FCC adopted an Order in March 2005 granting a
  waiver for MBOFDM and gated UWB technology to
  enable testing under normal operating conditions
• Order noted that FCC will initiate rule making in
  the future
• Petitions for reconsideration pending
• Industry is poised to introduce products
• Wireless USB
• In-home DTV distribution
• Several other new applications
• UWB standards are under consideration
  internationally
• Waivers are pending Vista/Cupid Multi Spectral
  Solutions Inc.

  paradigms for spectrum management
• FCC has provided for SDR cognitive radio (ET
  Docket No. 03-108, 2005)
• Revised equipment authorization rules
• Addressed security issues
• Synergy with secondary spectrum markets
• Reconsideration pending
• Much ongoing activity DYSPAN (Dynamic Spectrum

Broadband Over Power Line

• BPL rules adopted in October 2004 in ET Dkt
  04-37
• Included numerous provisions to protect against
  harmful interference
• Must include notching and remote shut-down
  capabilities to avoid causing Ix
• Must avoid certain aeronautical frequencies
• Must avoid operating on certain frequencies in
  some geographic areas (i.e., near Coast-Guard
  stations)
• Several petitions for reconsideration are pending

9
Other Pending Issues

• WCA petition at 57 64 GHz
• Requests higher power operation
• Some oppositions
• Progeny proceeding
• Requests rule changes for location monitoring
  service _at_ 915 MHz
• NPRM invites broad comment
• TV White Spaces proceeding (ET Dkt 02-380)
• FCC Adopted NPRM May 13, 2004
• 96 comments and 33 reply comments
• IEEE 802.22 planning further recommendations
• Next steps under consideration
• RF Exposure proceeding
• DTV Final Allotment Table

Presidential Spectrum Initiative

• Presidential Spectrum Initiative is led by the
  National Telecommunications Information Admin.
  (NTIA)
• Includes numerous recommendations to improve
  spectrum policy
• FCC is participating as a liaison
• Two actions of note
• Developing OET Frequency Assignment
  Coordination System (OFACs) to automate FCC/NTIA
  license coordination
• Considering a Notice of Inquiry on spectrum test
  bed

11
Medical Devices

• FCC granted waivers of the Part 95 Medical
  Implant Communications Service rules to Biotronik
  and DexCom
• Medtronic has filed a petition for rule making to
  expand the MICS rules
• Rule making planned in the very near future
• Consider changes to the MICS rules
• Invite broad comment on spectrum needs and issues
  for medical devices.

Conclusion

• Spectrum policy review is ongoing
• Extensive spectrum actions are already completed
  or under way
• Considerable future activity is planned
