State-of-the-Art Mobile Radio Measurements

The topic of this application note is mobile phone measurements – in theory and in practice. It discusses measurements according to the most common standard in use today, GSM.

The first, theoretical portion of this application note covers digital modulation and access methods in general. This is followed by an overview of the specific characteristics of the GSM standard as well as a summary of the most important mobile radio measurements.

The second, practical portion of this application note covers some of these measurements in detail and runs through them step by step. These measurements can be performed by small groups in labs.

The measurements and analysis of the results are intended to illustrate the theoretical portion of the application note and to deepen the reader's understanding.

All measurements are performed using the R&S®CMW500 wideband radio communication tester and an off the shelf mobile phone.
