In this paper, we propose the improvement of signal-strength aggregation with a special focus on Mobile Crowdsourcing scenarios by avoiding common issues related to the mishandling of log-scaled signal values, and by the proposal of a novel aggregation method based on interpolation. Our paper presents two clear contributions. First, we discuss the misuse of log-scaled signal-strength values, which is a persistent problem within the mobile computing community. We present the physical and mathematical formalities on how signal-strength values must be handled in a scientific environment. Second, we present a solution to the difficulties of aggregating signal strength in Mobile Crowdsourcing scenarios, as a low number of measurements and nonuniformity in spatial distribution. Our proposed method obtained consistently lower Root Mean Squared Error (RMSE) values than other commonly used methods at estimating the expected value of signal strength over an area. Both contributions of this paper are important for several recent pieces of research that characterize signal strength for an area of interest.<\/jats:p>","DOI":"10.3390\/s21041084","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T00:54:35Z","timestamp":1612486475000},"page":"1084","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Improving Signal-Strength Aggregation for Mobile Crowdsourcing Scenarios"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5769-2074","authenticated-orcid":false,"given":"Diego","family":"Madariaga","sequence":"first","affiliation":[{"name":"NIC Chile Research Labs, University of Chile, Santiago 8320000, Chile"},{"name":"Department of Computer Science, Millennium Institute Foundational Research on Data, University of Chile, Santiago 8320000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4132-5042","authenticated-orcid":false,"given":"Javier","family":"Madariaga","sequence":"additional","affiliation":[{"name":"NIC Chile Research Labs, University of Chile, Santiago 8320000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0036-2004","authenticated-orcid":false,"given":"Javier","family":"Bustos-Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"NIC Chile Research Labs, University of Chile, Santiago 8320000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3955-361X","authenticated-orcid":false,"given":"Benjamin","family":"Bustos","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Millennium Institute Foundational Research on Data, University of Chile, Santiago 8320000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sonntag, S., Schulte, L., and Manner, J.
