Further work on the re-examination of the protection requirements for the Radio Astronomy Service in light of the Broadband Fixed Wireless Access Multimedia Wireless Systems proposed for the 42.5 - 43.5 GHz frequency band |
Scope of Document
This document is the Final Report of the study by Transfinite Systems Ltd for the Radiocommunications Agency RA on "Further Work on the re-examination of the protection requirements for the Radio Astronomy Service in light of the Broadband Fixed Wireless Access Multimedia Wireless Systems proposed for the 42.5 - 43.5 GHz frequency band".
Objective and Approach of Study
This study builds on the work under a previous contract undertaken by TSL that examined this sharing scenario and proposed a methodology based on two stages:
1) Calculation of the Aggregate EIRP (A-EIRP) distributions including all transmitters within a defined area.
2) Use of the A-EIRP distributions to calculate an Exclusion Zone (EZ) required around a RAS site to protect it against interference. This EZ was defined based on the loss calculated using ITU-R Rec. P.452 propagation model.
