| contents | This paper analyzes the functional requirements and architectural considerations for Integrated Sensing and Communication ( ISAC) in a 5G Open Radio Access Network (OpenRAN) environment, with emphasis on secure and modular deployment. Focusing on a mono-static, half-duplex sensing approach, it evaluates radar setup options, signal types, and processing placement within the Radio Access Network ( RAN), considering performance and security implications. The proposed architecture minimizes hardware modifications by leveraging sniffer Radio Units (RU s) and existing OpenRAN fronthaul interfaces, while protecting sensitive In-phase and Quadrature (I/Q) data and control traffic against potential attacks. Security threats, such as passive sensing, spoofing, and privacy violations, are mapped to mitigation strategies within the OpenRAN framework. The result is a deployment blueprint applicable to both Public Land Mobile Networks ( PLMNs) and Non-Public Networks (NPNs), supporting future 6G ISAC capabilities in a standards-compliant manner. |
