While most technology courses may take a bottoms-up academic approach of explaining the subject matter with definitions and formulas, this course would attempt to explain all the concepts in as simple and as practical way as possible by providing real work examples and industry applications and showing real demos and visualizations of the concepts where ever possible. Our goal with this course is to make the complex world of Wi-Fi very easy to understand for beginners and also hopefully generate more interest among young engineers and college students to get inspired to develop a strong interest and build a successful career in this amazing and rapidly growing field of Wi-Fi. This course is fundamentally different from other Wi-Fi-related certifications and courses like CWNA as this course is more for engineers working on R&D of Wi-Fi technology and products and not related to deployment and or network administration.
