This presentation from the Deputy Chief of the FCC's Office of Engineering and Technology provides insights into current FCC spectrum activities, including broadband over power lines, proposed TV white spaces, public safety rebanding, and new broadband communication services. The spectrum allocation from 0 to 6 GHz, AWS bands, mobile and base station allocations, and various services like MSS and ATC are discussed. Additionally, topics such as dynamic frequency selection, UWB activities, cognitive radio, broadband over power line regulations, and pending issues like the TV white spaces proceeding and RF exposure are covered. The presentation also highlights ongoing activities in spectrum management and regulatory considerations for efficient spectrum utilization.

3650 MHz Proceeding • FCC Report and Order in March made 3650 – 3700 MHz available (ET Docket No. 04-151) • Licensed spectrum, open to all • Interference control: • Registration of base stations • “Contention based” protocol • Reconsideration is pending
5.8 GHz:Dynamic Frequency Selection • FCC Implemented Rules (ET Docket 03-122) to provide an additional 255 MHz of Spectrum for U-NII Devices based on DFS • PN invited comments to update record for measurement procedures Link Indoor Devices Link Devices to Nodes Provides A Total of 555 MHz of Spectrum! Link Nodes (Campus) 50 mW Indoor Use Only 250 mW 250 mW 1 W DFS DFS 5150 5250 5350 5470 5725 5825 Frequency (MHz)
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.
Cognitive Radio • SDR & Cognitive radio holds promise for revamping 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 Access Networks); IEEE P1900; SDR Forum; DARPA (Defense Applied Research Projects Agency) XG project
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
Other Pending Issues • WCA petition at 57 – 64 GHz • Requests higher power operation • Some oppositions • “Progeny” proceeding • Requests rule changes for location monitoring service @ 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
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
