Provisions forthe 37.5-43.5 GHz band (Ai 1.32)
• Resolution 84: sharing FS & FSS/BSS/MSS in 37.5-42.5 GHz
• Resolution 128: RAS protection in 42.5-43.5 GHz from new satellite systems
• Stakeholders: Fixed, Satellite (Defence) and RAS services
• APT/AUS proposals: existing pfd limits (Res 84); modified 5.551G limits (Res 128)

Provisions forthe 37.5-43.5 GHz band (Ai 1.32) - 2
• Outcomes: • Res 84: Existing Art. 21.4 pfd limits sufficient
(non-controversial)• Res 128: Revise 5.551G to reflect Rec. RA.769
limits for GSO and NGSO systems• + Region 2 (Americas) Resolution to allow
consultation for higher pfd levels in 42.5-42.77 GHz for 2% of time
• Compromise to resolve controversial positions.• No immediate follow-up needed.

Issues related tounwanted emissions (Ai 1.8)
• 1.8.1: Boundary between spurious and out-of-band emissions (App.S3)
• 1.8.2: Regulatory provisions from band-by-band studies (Rec 66) between passive and active space services.
• Affects RAS and Satellite services.• AUS/APT position: Support new “domain” definitions
(1.8.1); include BbB pfd limits into the Radio Regulations (1.8.2)
• 1.8.2 controversial. USA adamantly opposed to “hard” limits in RRs. Canada proposed “threshold” limits for triggering consultation only.

Issues related tounwanted emissions (Ai 1.8) - 2
• Outcomes:• 1.8.1: New definitions added to Art. 1 and App 3
(non-controversial)• 1.8.2: Compromise reached at Plenary. Footnote
& new Resolution on “consultation” after BbB threshold limits reached. Limits in agreed table.
• + Resolutions to continue BbB studies for RAS and EESS & add to limits table after studies.
• Action: Follow new studies.
