Final answer:
The first type of site survey to be performed for a wireless network should be a predictive site survey, which simulates wireless coverage using specialized software.
Step-by-step explanation:
When conducting a site survey for a wireless network, the first type of survey that should be performed is a predictive site survey. This type of survey uses specialized software to simulate and predict wireless coverage in a facility without the need to physically test for signal strength at every location. It takes into consideration the building's structure, material, and interference sources to create a model of the wireless network's performance. Once the predictive survey is complete, other types of site surveys, such as active or passive, can be conducted to verify the model's accuracy and make adjustments.
