The development of both connected radars and an IoT platform is detailed. The connected radars integrate commercial components, including a Raspberry Pi (RPi), a UWB radar, a standard enclosure, and a custom communication board featuring a 5G module. The IoT platform, which receives data from the radars via MQTT, is scalable, easily deployable, and supports radar management, data visualization, and external data access via an API. The solution was deployed and tested on campus, demonstrating real-time operation over a commercial 5G network with an estimated median latency between the radar and server of 75 ms. A preliminary evaluation conducted on a single radar during peak-hour traffic on a double-lane road, representing a challenging scenario, indicated a high detection rate of 94.81%, a low false detection rate of 1.02%, a high classification accuracy of 97.29%, and a high direction accuracy of 99.66%. These results validate the system\u2019s capability to deliver accurate traffic monitoring.<\/jats:p>","DOI":"10.3390\/s25103203","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T04:48:18Z","timestamp":1747716498000},"page":"3203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Development of a 5G-Connected Ultra-Wideband Radar Platform for Traffic Monitoring in a Campus Environment"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7781-557X","authenticated-orcid":false,"given":"David","family":"Mart\u00edn-Sacrist\u00e1n","sequence":"first","affiliation":[{"name":"iTEAM Research Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, Building 8G, D Access, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5114-3763","authenticated-orcid":false,"given":"Carlos","family":"Ravelo","sequence":"additional","affiliation":[{"name":"5G Communications for Future Industry Verticals S.L.
