A site survey report includes information about the physical layout, such as floor plans, existing cable runs, and potential interference sources. This is crucial to ensure that when network elements are installed, they can operate efficiently and effectively in that environment. Understanding the physical space helps in designing a network that is resilient and offers optimal coverage. Information about the company's policies or the types of devices that will be connected are not part of a site survey report, as these details are not related to the physical environment of the installation.
