Radio Measurements

This chapter outlines the main characteristics of narrowband and wideband radio measurements often employed in indoor wireless communications. Radio measurements are therefore an essential ingredient of the overall in‐building design process. The chapter describes the value of measurements for in‐building design projects, and presents different types of in‐building measurement systems and their characteristics. It then recognizes the impact of inaccuracies while performing measurements, and provides various guidelines and recommendations for in‐building testing. The chapter presents a brief overview of equipment for in‐building measurements, discussing some technical details of relevant components and equipment, such as transmitters, receivers, feeders and antennas. It discusses the role of having a well‐documented measurement campaign, especially when postanalysis of the collected data is to be performed. Finally, the chapter presents tips and tricks for effective measurements, along with some walk route guidelines and recommendations.
