After designing a WLAN infrastructure using predictive design software.

An AP-on-a-Stick survey is a method of validating a predictive design by placing an AP at each proposed location and measuring the signal coverage and performance. This allows the designer to verify the accuracy of the predictive design and make any adjustments if needed. An AP-on-a-Stick survey is more cost-effective and time-efficient than deploying all the APs and performing a passive or active site survey, which would require installing the APs, cabling, power, and network infrastructure. Using a client device to measure the signal from the AP locations is not a reliable way of validating the design, as it does not account for the interference, noise, and multipath effects that may affect the actual AP performance. References: 1: CWDP Certified Wireless Design Professional Official Study Guide: Exam PW0-304, Chapter 5, page 163.
