Overview

This Ekahau Pro training course provides a comprehensive coverage of Wi-Fi network Planning, Design, Surveying and Reporting using Ekahau Pro (formerly Ekahau Site Survey). Focussed lecture sessions and hands-on practical exercises with Ekahau Pro, plus on-site survey and predictive design exercises, are key features of this course. Attendees also learn the key aspects of Wi-Fi life cycle management, including 802.11 / Wi-Fi network and RF essentials, Pre- and Post-deployment site surveys, Predictive design, RF Spectrum analysis, plus many undocumented tips and techniques for expert Wi-Fi network engineering.
