DESCRIPTION
This heavyweight webinar matchup features two of the most prominent Wi-Fi architectures today. In one corner, standing 2” tall and 18”x18” is a WLAN controller. And in the other corner, with a height that stretches for miles, is a cloud management platform. When evaluating WLAN solutions for 802.11ac deployments, these two architectures will most likely go head-to-head and factor prominently in your decision-making. In this webinar, we’ll equip you with the tools to referee such a bout to ensure your organization is the one coming out on top. We’ll examine: - Central controller-based infrastructure - Cloud controller-based architecture - Distributed control with cloud-based management
