Along with the study of the technologies used in the eduroam network, a global roaming service conceived by the European association of academic and research networks, the primary goal of this paper are the measurements of its performance, the discovery of potential flaws and the suggestions meant to solve said problems. The technologies used in the eduroam network are extremely safe, reliable, accessible and easy to use by the end user. The quality of network access was measured by testing the data transmission rates and network response in several key locations with the conclusion how the network speeds are more than adequate for today's users with some exceptions. The measurements indicate how some locations have problems with capacity and/or latency. Definitely problems that should be paid attention to. The coverage was measured with an advanced program designed to map wireless networks. The results are georeferenced and displayed in a graphical format while providing acceptable results. A big part of Zagreb's city center is covered by teh eduroam network. It is important to mention how the eduroam network is still in development and how most other parts of the city aren't properly covered yet. After analyzing the results certain actions were suggested which should be taken in order for the network to become more reliable and available for the end users.
