Abstract

The article presents a modified technique for measuring the field strength of broadband and narrowband interference from automotive equipment using GSM and UMTS technologies for data transmission, as well as making a voice call. The results of testing the methodology are presented using the example of measuring the level of radio interference of automobile devices for calling in-vehicle emergency services.
