Predeployment Indoor Wireless Site Survey: Checklist

C.

Before conducting a predeployment indoor wireless site survey, it is essential to have the necessary information to ensure that the wireless network meets the customer's requirements. This includes identifying the areas of the facility in which the customer wants to deploy wireless, the client devices and applications that will use wireless at the facility, and the Layer 2 security requirements for the WLAN.

Therefore, options A, D, and E are critical items that should be obtained before starting the project, as they provide essential information that will guide the design and deployment of the wireless network.

Option B, architecture drawings of the facility, is also necessary to determine the physical layout of the facility, including the walls, doors, and other physical barriers that may affect the wireless signal's propagation. These drawings provide information about the size and shape of the facility, which is critical in designing the wireless network.

Option C, topographical maps, however, are not necessary for an indoor wireless site survey. Topographical maps typically provide information about the natural features of an outdoor area, such as hills, valleys, and bodies of water. As such, they are not relevant to the design and deployment of an indoor wireless network.

In conclusion, the correct answer is C, topographical maps, as they are not needed before starting a predeployment indoor wireless site survey.
