The paper therefore proposes that the resolution bandwidth of the super heterodyne EMI test receiver used for measurements and the dwell time should be adjusted to match the control parameters of the random modulation scheme. The use of different values for resolution bandwidth and dwell time is demonstrated and measurements for random and fixed modulation schemes are compared.","PeriodicalId":73281,"journal":{"name":"IEEE electromagnetic compatibility magazine","volume":"11 1","pages":"84-92"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62489134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the electromagnetic compatibility (EMC) requirements is critical for preparing future device designs to conform to the upcoming standards. This article provides an overview of EMC's role in the certification process and provides an updated standardization guide, comparing emissions and immunity tests of the latest 3GPP/ETSI and ITU recommendations. We discuss the test methodologies and challenges when setting up EMC test facilities, especially for OTA at the FR2 band. We also provide an example of equipment selection as a guide for 5G 3GPP RF conformance tests for User Equipment (UE) and Base Station (BS). Finally, thinking about the future, we dive into the next-generation wireless communication world to provide insights on how 6G technology advancements would impact EMC.","PeriodicalId":73281,"journal":{"name":"IEEE electromagnetic compatibility magazine","volume":"11 1","pages":"63-72"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62488312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluated classical Z score results and overall performance of the participant EMC test laboratories in ILC program are affected by these factors. The performance improvement techniques to address the influencing factors and eliminate the deviation in test results of ILC program are outlined in detail. A case study was conducted in the frequency range from 30 MHz to 1 GHz, as the deviation in Z score results is predominant below 1 GHz. The importance of awareness required to conduct ILC program accurately with minimum possible errors is highlighted in this paper.","PeriodicalId":73281,"journal":{"name":"IEEE electromagnetic compatibility magazine","volume":"11 1","pages":"53-61"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62488699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
