Six different frequency bands are considered, ranging from 2.6\u00a0GHz in the ultra high frequency (UHF) band to 73\u00a0GHz in the millimeter wave bands (mmWaves), using both single\u2010slope and two\u2010slope path\u2010loss models. We start by comparing four urban path loss models for UHF: the urban\/vehicular and pedestrian test environment from the ITU\u2010R M. 1255 Report, which includes the two\u2010slope urban micro line\u2010of\u2010sight (LoS) and NLoS, from the ITU\u2010R 2135 Report. Then, we consider mmWaves taking into consideration the modified Friis propagation model, followed by an analysis of the throughput for the 2.6, 3.5, 28, 38, 60, and 73\u00a0GHz frequency bands. We have found that the signal\u2010to\u2010interference\u2010plus\u2010noise ratio, as estimated with the more realistic two\u2010slope model, is lower for devices that are within the break\u2010point of the transmitter, which is a small distance in the UHF\/SHF band. As a result, spectral efficiency is higher with mmWaves than with UHF\/SHF spectrum when cell radius is under 40\u00a0m but not when cells are larger. Consequently, mmWaves spectrum will be more valuable as cells get small. We also find that capacity as estimated with the two\u2010slope model is considerably smaller than one would obtain with the one\u2010slope model when cells are small but there is little difference in the models when cells are larger. Thus, as cells get smaller, the use of one\u2010slope models may underestimate the number of cells that must be deployed.<\/jats:p>","DOI":"10.1029\/2020rs007150","type":"journal-article","created":{"date-parts":[[2021,2,3]],"date-time":"2021-02-03T22:01:53Z","timestamp":1612389713000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Impact of the Propagation Model on the Capacity in Small\u2010Cell Networks: Comparison Between the UHF\/SHF and the Millimeter Wavebands"],"prefix":"10.1029","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6546-5277","authenticated-orcid":false,"given":"Emanuel","family":"Teixeira","sequence":"first","affiliation":[{"name":"Faculdade de Engenharia Instituto de Telecomunica\u00e7\u00f5es \u2010 DEM Universidade da Beira Interior  Covilh\u00e3 Portugal"}]},{"given":"Sofia","family":"Sousa","sequence":"additional","affiliation":[{"name":"Faculdade de Engenharia Instituto de Telecomunica\u00e7\u00f5es \u2010 DEM Universidade da Beira Interior  Covilh\u00e3 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9680-123X","authenticated-orcid":false,"given":"Fernando J.","family":"Velez","sequence":"additional","affiliation":[{"name":"Faculdade de Engenharia Instituto de Telecomunica\u00e7\u00f5es \u2010 DEM Universidade da Beira Interior  Covilh\u00e3 Portugal"}]},{"given":"Jon M.","family":"Peha","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering Department of Engineering &amp; Public Policy Carnegie Mellon University  Pittsburgh PA USA"}]}],"member":"13","published-online":{"date-parts":[[2021,4,29]]},"reference":[{"unstructured":"3GPP.
