This study provides a compatibility analysisbetween air surveillance radars (ASR) and meteorological radars and IMT systems in the 2 700-2 900 MHz band. It describes technical matters related to the methodology, protection criteria, and mitigation techniques used to analyze potential compatibility. Details that describe the IMT and radar characteristics,ASR and meteorological radar interference criteria and IMT interference criteria used for the studies discussed in this text were taken from various ITU-R Recommendations and are summarized in Appendix 1 to Annex 1- Study A Compatibility of air surveillance radars and meteorological radar with IMT systems within the 2 700-2 900 MHz band. Appendix 2 to Annex 1 provides results of IMT sharing studies with ASR’s Types A, B and C radars as defined in Recommendation ITU-R M.1464 within the 2 700-2 900 MHz band. Appendix 3 to Annex 1 presents results of IMT sharing studies with meteorological radars as defined in Recommendation ITU-R M.1464 Type G within the 2 700-2 900 MHz band. Appendix 4 to Annex 1 present results of studies that show what the impact of ASR and meteorological radar operations have upon IMT systems operating within the 2 700-2 900 MHz band. Annex 2 presents the results of additional sharing studiesthat incorporate interference mitigation techniques.Appendix 1 to Annex 2 describes the analysis methodology that was used for those studies.
