1. International Telecommunication Union World Radiocommunication Conference 2003 9 June to 4 July Geneva, Switzerland Australian WRC-03 Delegation Document No: 9 Source: ACA, Date: 30 April 2003

2. Provisions for the 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)

3. Provisions for the 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.

4. Issues related to unwanted 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.

5. Issues related to unwanted 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.
