| Agenda Item: |
Agenda 1.20 |
| Resolution(s): |
Resolution 738 [COM4/14] |
| Description of work: |
This agenda item refers to compatibility between the EESS (passive) service and active services with allocations in adjacent or nearby bands. ITU-R Recommendation SM 1633 undertook a band by band survey of compatibility between passive and active services in adjacent bands. However this Recommendation did not cover all service + band pairs, and so further work is required:
i) The Resolution identifies 7 band and service combinations for further study, involving frequencies between 1 400 MHz and 50.4 GHz, and the fixed, mobile, fixed satellite, and radiolocation services.
ii) In addition work is required to consider the impact of implementing the values in Rec. 1633 on the fixed service (excluding HAPS) in Regions 2 and 3 in bands around 30 GHz and 50 GHz.

| How Visualyse products can help: |
Visualyse Professional can be used to calculate levels of in-band or out-of-band interference into EESS (passive) from all the active services required including mobile, fixed, radiolocation, and fixed satellite (GSO and non-GSO) systems, calculating PFD and EPFD levels where necessary. |
| 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 relevant ITU-R Working Parties. We have extensive experience in issues relating to sharing with the EESS from work for analysing compatibility between EESS and a non-GSO FSS operator, of out-of-band analysis, and of calculation of EPFD and PFD from numerous sharing studies. |
