WRC 2019 Agenda Item Details

Agenda Item:	Agenda Item 1.4
Resolution(s):	Resolution 557 [COM6/9] (WRC-15)
Description of work:	This agenda item relates to consideration of the results of studies in accordance with Resolution 557 [COM6/9] (WRC-15), and review, and revise if necessary, the limitations mentioned in Annex 7 to Appendix 30 (Rev.WRC-12), while ensuring the protection of, and without imposing additional constraints on, assignments in the Plan and the List and the future development of the broadcasting-satellite service within the Plan, and existing and planned fixed-satellite service networks.
Comments:	The Resolution notes that parts of 11.7 - 12.75 GHz band are used by the BSS and FSS with allocations varying by Regions and there is a need for the plan to take account of FSS networks while continuing to permit development of BSS assignments.
Lead Working Party(s):	WP 4A
Involved Working Parties:	WP 3M
How Visualyse products can help:	Visualyse Professional can model but BSS and FSS systems and is able to read from the SRS databases for both services. It is able to undertaken analysis across a service area involving large numbers of systems, with gain patterns defined either via GIMS style shaped beams or ellipses. Analysis can be undertaken using metrics including DT/T (via I/N), C/I, C/(N+I) or PFD. In addition, Visualyse GSO is designed to undertake coordination trigger (Appendix 5) or detailed coordination between GSO networks. The analysis could either be undertaken assuming clear air (free space) propagation or including gaseous attenuation and/or rain P.618.
How Transfinite consultants can help:	We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at the ITU-R WP 4A. We have detailed experience in satellite coordination including both the FSS and BSS, planned and unplanned bands.
