WRC 2007 Agenda Item Details

Agenda Item: Resolution 229 [COM5/16]
Resolution(s): Resolution 229 [COM5/16]
Description of work: This resolution refers to the use of the bands between 5 150 and 5 725 by wireless access networks including radio local area networks. A number of changes in allocations were made in this 5 GHz band during WRC-03, for example additional allocations for the mobile service, and upgrades for other services such as radiolocation. This resolution defines regulations to facilitate use of this band by the various services allocated. It also calls upon further work: i) on the regulatory mechanisms and further mitigation techniques to avoid incompatibilities caused by the aggregate interference from large numbers of WAS devices into non-GSO FSS uplinks in the 5 150 - 5 250 MHz band; ii) on mitigation techniques to protect EESS from stations in the mobile service iii) on test methods and procedures for the implementation of dynamic frequency selection
Lead Working Party(s): WP 8A
Involved Working Parties: WP 4A, WP 7C, WP 8A, WP 9B, WP 9D
How Visualyse products can help: Visualyse Professional can be used to examine the 5 GHz sharing issues such as WAS into non-GSO MSS feeder links or into EESS (active) and SRS (active) systems. It can also model sharing scenarios with other services allocated in this band, including radiolocation and radiodetermination.
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 a detailed understanding of the issues in this band from our work in the development of some of the Recommendations, many sharing studies, and support of a client at ITU-R meetings on this subject.
