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

  • 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

    • CEPT countries believe that outdoor RLAN operation is not feasible
      • Difficult to enforce EIRP mask

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 °

  • 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

  • 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

      • More studies required for other EESS systems (wideband SARs)
    • RLANs vs RADIOLOCATION
