The obtained results are compared in order to define the limit of applicability of each technique. In addition, numerical simulations are performed by applying the finite-difference time-domain method in order to assess the effects of the geometry of the test configuration on the obtained results.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121577063","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 analysis is conducted experimentally following a cross-layer approach and through the deployment of a proper testbed within a semi-anechoic chamber. The purpose is to investigate on the effects of some common types of interference on a WLAN supporting VoIP applications, and to deduce from the experiments valuable hints for improving the setup of a WLAN in the presence of interference.

Comparison between the IEC 61000-4-21 and the IEC 61000-4-3 shows that the testing time of the first is relatively high. So, a new method is presented here that uses a selective source-mode tuning in a reverberation chamber in order to reduce the difference of testing time. The work has been made in the perspective of making immunity testing according the IEC 61000-4-21 standard at HIRF (High Intensity Radiated Fields) in the frequency band of mobile phone and GPS systems (800-2500 MHz). The three components of the E-field, the forward and reverse output powers and the displacement of the two LPDA (Log Periodic Dipole Array) antennas have been measured for each of the 24 tuner positions, at eight locations of the working volume and at twenty two frequencies within the frequency range of interest. The measurements are organized in function of the requirements of the standard, i.e., the field uniformity. The results show that with this low number of samples, the compromise to have low testing time with compliance with the standard is achieved.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116132763","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}
