What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)

• A.It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey.
• B.Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP's expected coverage pattern in almost real-time.
• C.The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.
• D.Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.
• E.Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveyingare less reliable.
