Today, Wi-Fi networks can be found almost everywhere: in homes, businesses, hotels, restaurants, transportation, streets, etc. Research subject. In this study, we analyze the performance of outdoor and indoor wireless local area networks. Method. To achieve this goal, the following empirical research methods were used: measurement, experiment, and comparison. Core results. In the first part of the study, experimental data on radio frequency spectrum usage around and inside St. Petersburg State University of Telecommunications are provided. The second part of the study is devoted to the peculiarities of outdoor and indoor Wi-Fi. The effective data rate, retry rate, and noise floor are compared for the 2.4 and 5 GHz frequency bands. Practical relevance. The obtained results can be used for design and optimization of outdoor Wi-Fi networks.
