In 3GPP, Integrated Sensing and Communications (ISAC) is discussed for utilizing mobile communication systems for wireless sensing. We have constructed a wireless sensing system that can capture signals from multiple base stations and frequencies, using software radios and open databases for ISAC use-case evaluation. Using this system, we acquired LTE signals from actual base stations and evaluated human detection in indoor conference rooms. In the evaluation using the acquired CSI phase, it was confirmed that person detection was possible while data quantity was reduced by selecting appropriate frequencies and resource blocks.
