2. NSMA Working Group 32012 Conference Report • Mission • Participation • Meetings • Results • Issues NSMA Spectrum Management 2012

3. Mission • Develop specific coordination procedures • Create recommendations for industry guidance • Develop responsible spectrum use policy • Interpret FCC rules • Preparation of regulatory filings • Provide an industry forum for spectrum discussions NSMA Spectrum Management 2012

4. Participation • NSMA is an open industry forum available to all who wish to participate and contribute to development of responsible spectrum use recommendations and policy. • Working Group 3 is the place to start if you would like NSMA to consider a spectrum-related issue. • Issues are handled as part of the WG3 agenda or spun off to a separate committee or working group. • You are invited to come and bring your issues! NSMA Spectrum Management 2012

5. WG3 Participants • Frequency coordinators • Radio manufacturers • Spectrum managers • Service providers • System Vendors • Spectrum users • Broadcasters • Consultants • Licensees NSMA Spectrum Management 2012

6. Meetings • Meetings are by monthly teleconference. • Agendas include background so new participants can come up to speed quickly. • At most meetings we move forward on or track about 20 spectrum issues. • Standards • Regulatory • Technical NSMA Spectrum Management 2012

7. Results • NSMA industry recommendations • FCC spectrum filings • FCC visits • Technical spectrum support to other industry groups • Forum for exchange of information on spectrum issues NSMA Spectrum Management 2012

8. Recommendations • Mixed High-Low Frequency Plans and Reflection Interference (Bucking) recommendation • Approved • Dave Meyer, Editor • Adaptive Modulation recommendation • Ian Marshall, Editor • BAS/FS Coordination recommendation • Dave Meyer and Kelly Williams, Editors • Special committee meets every 3 weeks • Strong participation by broadcasters NSMA Spectrum Management 2012

9. FCC activity • NSMA filed comments and reply comments on multiple issues in the FCC broadband proceeding WT10-153 • Ex parte filings on WSI proposals • Technical support to FWCC • Text contributions • FCC visits • Response to FCC questions • Tracking regulatory issues NSMA Spectrum Management 2012

10. Issues • Adaptive modulation- two ranges for adaptive modulation • Above FCC minimum payload requirement • Mines capacity out of fade margin • No rule restrictions- implemented on many links • Below FCC minimum payload requirement • Link would otherwise be down • Maintain synchronization • Continue with reduced traffic load • Requires 99.95% availability design NSMA Spectrum Management 2012

13. Issues • 4 GHz band utilization • Maintain compatibility with incumbent earth station use • Consider possible applicability of the band for short haul transport • Enable use of smaller antennas for short-range low-power use • Consider low-power, spread spectrum opportunities- low power density, wide channels • Revise the FS band plan • Attractive for traditional point-to-point use • Compatibility with ITU band plan NSMA Spectrum Management 2012

14. Issues • Broadcast Auxiliary Service – Fixed Service sharing • 7 and 13 GHz Bands - in areas w/o TV pickup • NSMA and SBE have launched the BAS-FS Coordination Committee to develop an NSMA recommendation to address sharing. • Co-editors are Dave Meyer and Kelly Williams • Next BAS Coordination Committee meeting: 1:30 PM, Tuesday, May 22nd 877-888-4443, #, 5379190# Please attend if you would like to participate.  NSMA Spectrum Management 2012

15. Issues • WSI has proposed point-to-multipoint operation in the 6 GHz band and all other transport bands • NSMA has done periodic FCC filings opposing • Commission rejected the auxiliary station proposal indicating it would create a perverse incentive for applicants to propose excessive power for their auxiliary stations. • Revision of license buildout rules for area licenses in the 28 and 38 GHz Bands • Use of small antennas in FS bands • 18 GHz channel aggregation; e.g., three 50 MHz channels into a 150 MHz channel NSMA Spectrum Management 2012

16. Issues • Improved coordination procedures • FCC database information tracking • Reports by FCC and GAO to Congress – coordination failures in 11, 18 and 23 GHz bands, auctions? • FCC definition of rural • Provided input to FWCC which filed with FCC NSMA Spectrum Management 2012

17. Tracking Issues • 2750-2835 MHz band reallocation in Canada • 3650-3700 MHz band activity • Interference to earth stations in 3.7-4.2 GHz band • Additional in-band interference protection • LightSquared – GPS • Metropolitan Area Networks (MAN) • 60 MHz channels in lower 6 GHz and 80 MHz channels in 11 GHz bands NSMA Spectrum Management 2012

18. Tracking Issues • Industry Canada: 10 MHz channels in 10 GHz band • Public safety operation in 4940-4990 MHz • Identification of parties of interest in proceedings • Renewal and discontinuance of operation, Docket 10-112 • Migratory birds and towers NSMA Spectrum Management 2012

19. Future Issues • TIA Technical Service Bulletin 10 review: • Automatic transmit power control section • Analog systems information • Add digital systems information • 10 dB difference between long and short-term • BAS – FS coordination: consider adding to TSB10 • IP-based systems: consider adding • ESV issues • 7125-8500 government band consideration for shared FS use NSMA Spectrum Management 2012

20. Summary • NSMA WG3 is an open forum • You are invited to join and bring spectrum issues. • Thank you! NSMA Spectrum Management 2012
