  8. Options to allow theoperation of RLANs • Option 1: Primary Allocation • With/without footnotes • MS and/or FS • Option 2: Secondary Allocation • With/without footnotes • MS and/or FS • Option 3: No allocation • With footnote to allow the RLANs to operate • Option 4: No allocation/no footnote • Status quo • Domestic rules would continue to allow RLANs to operate in Canada and in the US Rebecca Chan, Industry Canada

  9. 5150 – 5250 MHz Rebecca Chan, Industry Canada

  10. 5150 5250 MHz ARNS FSS(E-s) MS/ms – RLANs 5150 – 5250 MHz ITU-R Status • Sharing studies within the ITU-R are complete • Recommendation ITU-R M.1454 (EIRP limit and operational restrictions on RLANs) • Recommendation ITU-R S.1426 (Aggregate power flux-density limits at the FSS for RLANs) • Recommendation ITU-R S.1247 (Methodology and criterion to assess interference from RLANs to NGSO MSS feederlinks) Rebecca Chan, Industry Canada

  11. 5150 5250 MHz ARNS FSS(E-s) MS/ms – RLANs 5150 – 5250 MHzCanadian Proposal • Secondary fixed and mobile allocation • To protect primary services • To allow for flexibility in different countries: transportable devices are classified under fixed or mobile services in different countries • Limit the usage to wireless access systems including RLANs only. • Systems fitting the description of M.1450 (Characteristics of RLANs) • Through footnote in the allocation table, technical constraints on RLANs: • Indoor use only • Max EIRP = 200 mW and -20dBW/MHz • Aggregate pfd from RLANs into NGSO shall not exceed -124 – 20 log(hsat/1414) dBW/m2/MHz Rebecca Chan, Industry Canada

  13. 5250 – 5350 MHz Rebecca Chan, Industry Canada

  14. 5250 – 5350 MHz ITU-R Status 5250 5350 MHz • Sharing studies on going • RLANs vs EESS (and SRS) • WP 7C, JRG 8A-9B • CEPT countries believe that outdoor RLAN operation is not feasible • Difficult to enforce EIRP mask • Canadian studies show that given certain technical constraints, sharing between indoor/outdoor RLANs with EESS is feasible EESS SRS RADIOLOC MS/ms – RLANs FS/fs – FWA (R3) Rebecca Chan, Industry Canada

  15. 5250 – 5350 MHz ITU-R Status 5250 5350 MHz • RLANs vs RADIOLOCATION • WP 8B, JRG 8A-9B (next meeting: April/May 2002) • Studies are required to confirm the feasibility of dynamic frequency selection as an effective technique to mitigate interference to/from RLANs to/from Radiolocation service EESS SRS RADIOLOC MS/ms – RLANs FS/fs – FWA (R3) Rebecca Chan, Industry Canada

  16. 5250 5350 MHz EESS SRS RADIOLOC MS/ms – RLANs FS/fs – FWA (R3) 5250 – 5350 MHz Canadian proposal • Secondary fixed and mobile allocation • Protection of primary services • Canada operates RADARSat program under EESS • flexibility for administration • Limit the usage to wireless access systems including RLANs only. • Rec. ITU-R M.1450 only • Through footnote, technical constraints on RLANs: • Indoor and outdoor use • Max transmitter power = 250 mW or -10 dBW/MHz • Max EIRP 1W or -13 dBW/MHz • Max EIRP for outdoor systems should not exceed the following values for elevation angle  above the local horizontal plane: -13 dBW/MHz for 0° <=  < 5 ° -13 -0.711 ( -5) dBW/MHz for 5° <=  < 40 ° -35.9 -1.222(-40) dBW/MHz for 40° <=  < 45 ° -42 dBW/MHz for  >= 45 ° Rebecca Chan, Industry Canada

  18. 5460 - 5725 MHz Rebecca Chan, Industry Canada

  19. 5470 5460 5570 MHz RADIONAV MARITIME RADIONAV EESS SRS RADIOLOCATION MS/ms – RLANs 5460 - 5570 MHzITU-R Status – Allocation to allow the operation of RLANs • Sharing studies ongoing • Similar sharing environment, but “sharing with” as opposed to “protection” of EESS • RLANs vs EESS (and SRS) • WP 7C, JRG 8A-9B • CEPT countries believe that outdoor RLAN operation is feasible with 1W EIRP • Canadian studies show that given certain technical constraints, sharing between indoor/outdoor RLANs with EESS is feasible. Without the EIRP mask, EESS service will receive significant interference from RLANs Rebecca Chan, Industry Canada

  20. 5470 5460 5570 MHz RADIONAV MARITIME RADIONAV EESS SRS RADIOLOCATION MS/ms – RLANs 5460 - 5570 MHzITU-R Status – Allocation to allow the operation of RLANs • Sharing studies ongoing • RLANs vs RADIOLOCATION • JRG 8A-9B, WP 8B (next meeting: April/May, 2002) • CEPT countries believe that outdoor RLAN operation is feasible with 1W EIRP • Sharing is dependent on the feasibility of DFS as a mitigation technique Rebecca Chan, Industry Canada

  21. 5470 5460 5570 MHz RADIONAV MARITIME RADIONAV EESS SRS RADIOLOCATION MS/ms – RLANs 5460 - 5570 MHzITU-R Status – Extension of EESS • CEPT countries could support EESS • “1W HIPERLAN operation would not be compatible with the EESS which have similar protection requirements as those within the existing EESS allocations.” “Within Europe, the main interest in this allocation is for measurements over oceans and so the parallel proposals for EESS and MS allocations may not conflict” • Canadian studies show that given certain technical constraints, sharing between indoor/outdoor RLANs with EESS is feasible. Without the EIRP mask on the outdoor RLANs, EESS service will receive significant interference from RLANs Rebecca Chan, Industry Canada

  22. 5470 5460 5570 MHz RADIONAV MARITIME RADIONAV EESS SRS RADIOLOCATION MS/ms – RLANs 5460 - 5570 MHzITU-R Status – Upgrade of Radiolocation to Primary • Canadian position: • Upgrade to primary can be supported • Conditional upon protection of EESS and ARNS Rebecca Chan, Industry Canada

  23. 5470 5460 5570 MHz RADIONAV MARITIME RADIONAV EESS SRS RADIOLOCATION MS/ms – RLANs 5460 - 5570 MHzCanadian Proposals • Pending • EESS vs RLANs • EIRP mask for outdoor RLANs similar to 5250-5350 MHz to protect same EESS system • More studies required for other EESS systems (wideband SARs) • RLANs vs RADIOLOCATION • Studies on-going – DFS as a mitigation technique Rebecca Chan, Industry Canada

  24. 5570 5725 MHz 5650 MARITIME RADIONAV Amateur Srs (deep space) RADIOLOC RADIOLOC MS/ms – RLANs 5570 – 5725 MHzCanadian proposal • Pending • RLANs vs RADIOLOCATION • Studies ongoing – DFS as a mitigation technique Rebecca Chan, Industry Canada

  27.
