WRC-12: Agenda Item 1.14

> to consider requirements for new applications in the radiolocation service and review allocations or regulatory provisions for implementation of the radiolocation service in the range 30‑300 MHz, in accordance with Resolution 611 (WRC-07)

> This agenda item was coordinated by the Department of Defence with a small stakeholder group participating.



> Predominantly driven by the RCC for space debris tracking

> Agenda Item focused on 154 – 156 MHz as the preferred frequency range to solve the requirements of the Agenda Item

> Australia had little concern with this focused frequency range



APT views on the matter seemed fluent, with some countries changing their mind at the final APG. Overall support for the Allocation in 154-156 MHz as long as incumbents were protected.

Other variations making up the APT views were:> Any additional allocation to radiolocation service in the 154-156 MHz may result in unacceptable

interference to existing services and hinder future technological development and efficient spectrum use within Region 3;

> Although it may be possible to consider a country footnote within the 154-156 MHz range in order to accommodate new applications in the radiolocation service limited to Region 1, the protection criteria agreed on a global basis should be applied in this case;

> APT Members also have a view that the interference protection criteria of field strength of 12 dB(µV/m) is inappropriate to provide adequate protection of MS stations in Region 3. The protection criteria in Recommendation ITU-R M.1808, based on I/N values, shall be applied in protection of existing services and their future development;

> APT Members do not support the allocation of the band 154-156 MHz for Radiolocation service within Region 3. Therefore APT Members support Method D.

> Some APT countries support Method C2.



Outcome> WRC agreed to an allocation to the RLS between 154-156 MHz via a

footnote including a list of countries. This is a combination of Method B with allocation made and agreement seeking procedure under RR No. 9.21, and Method C via footnote.

> Protection requirements are specified in the footnote. > This is in line with the Australian position. > It is noteworthy that Iran and China, APT countries who had opposed

an allocation in Region 3 at last APT meeting had their names included in the footnote as countries where an allocation is made.
