Description
This technical webinar will discuss the concept of interference in WiFi networks and will begin by reviewing the evolution of WiFi technology over the last two decades. Next, we will review spectrum as the most precious resource for wireless communication systems. Focusing on home networks, we’ll evaluate the impact of interference on both WiFi data and video distribution. Afterwards, WiFi qualification and the installation process will be described and the significance of DFS channels demonstrated. The practical segment of this webinar will be interference measurement and troubleshooting.

In addition, MIMO will be introduced as fundamental component of advanced WiFi systems and a prominent way to mitigate interference. MIMO technical concepts and configurations including Multi-User MIMO will be reviewed. In conclusion, this webinar will provide insight on how future WiFi networks can mitigate interference.

Audience
Engineers, Installers, Technical Managers, Network Operators, CTOs and technical executives
