COLLAZO-GARCIA, Antonio  and  CASAS, Sandra. Comparison of mobile QoE: an unsupervised field study in Argentina and Cuba. Dyna rev.fac.nac.minas [online]. 2022, vol.89, n.220, pp.72-80.  Epub Sep 12, 2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v89n220.97894.

This article presents the findings of an unsupervised field study conducted over 31 days in Argentina and Cuba in order to explore mobile QoE. We also analyzed the correspondence between the objective observations and users' opinions to identify contextual conditions that could have influenced the study's results. Using their own mobile devices in everyday contexts, 95 users from Argentina and Cuba interacted with Covidlnfo app, thereby recording values for eight objective metrics as well as their opinions. The total data set collected consisted of 41,144 records. Analysis of the Covidlnfo application yielded positive QoE results in both countries, as 88% and 70% of the objective metrics in Argentina and Cuba, respectively, were optimal. The main difference between the two countries is the type of connection: In Argentina, WiFi networks are predominant, while the trend in Cuba is mobile data connections.
