Hi,
I suppose it would be the best for you to get in touch with local Extreme SE or sales representative so they can guide you more thoroughly.
Smart OmniEdge is about the entire edge, WLAN but also LAN. Automation that leads to higher security and easier administration. Single pane of glass management, end-to-end security without static configuration of access ports, AI applications, readiness for IOT stuff... That's just in brief. Maybe this you will find useful: https://www.extremenetworks.com/resources/at-a-glance/top-8-things-you-need-to-know-about-smart-omniedge/
Hope that helps,
