WRC 2007 Agenda Item Details

Agenda Item: Resolution 143 [COM5/6]
Resolution(s): Resolution 143 [COM5/6]
Description of work: This resolution relates to the development of high density applications in the fixed satellite service (HDFSS). A number of frequency bands have been identified in 5.BC03 as potentially suitable, and the Resolution gives guidelines as to ways to implement HDFSS - for example harmonisation of global spectrum. Particular areas that could benefit from further work are: a) development of simplified coordination procedures to facilitate the rapid introduction of HD-FSS terminals; b) study into the potential impact of the deployment of HDFSS in the upper part of the 48.2 - 50.2 GHz band on the satellite passive bands in the adjacent 50.2 - 50.4 GHz band, noting that 5.340 states that these passive services should not impose undue constraints on such services as the HDFSS
Lead Working Party(s): 4-9S
Involved Working Parties: 4-9S
How Visualyse products can help: We have two products that can assist in this agenda item: Visualyse Coordinate is our product for rapid and easy coordination of the introduction of satellite earth stations, with one-click interference analysis and integration with terrain and assignment databases; Visualyse Professional can be used to analyse sharing scenarios between FSS (uplink or downlink, GSO or non-GSO) and other services that could share these bands, including out-of-band emissions into EESS (passive) and space research (passive).
How Transfinite consultants can help: We can undertake studies including analysis of sharing between the services covered by this resolution, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at relevant ITU-R Working Parties. We have extensive experience in issues relating to sharing with the fixed service from our development of Visualyse Coordinate, and could develop a simplified methodology in a form such as a PDNR. We have also experience in sharing between FSS applications and many other services from previous studies undertaken.
