Implementing a live distributed antenna system (DAS) configuration from a virtual DAS design using an original equipment manufacturer (OEM) specific software system in a real DAS is disclosed herein. In exemplary aspects disclosed herein, the OEM specific software system enables a designer to create, save, import, modify and/or preconfigure a virtual DAS in a virtual DAS configuration file(s) using OEM specific software tools resident in the real DAS. The OEM specific software tools could include functionality such as the ability to incorporate and enforce OEM design constraints of the real DAS. The configuration file(s) can then be subsequently implemented to modify and/or configure live equipment of a real DAS. The OEM specific software tools and local execution of the virtual DAS facilitates, improves, and optimizes DAS design and execution, and ensures that the real DAS substantially matches the DAS design.
