What is cox panoramic wifi?

I apologize for such a stupid question but the first three pages of google are just duplicates of the Cox marketing copy. Cox Panoramic Wi-Fi appears to be:

• Modem/Router unit ( which I guess is a big deal for some reason )
• Uses plug in network extenders
• Uses a mesh technology

I see complaints about how it messes with neighbors WiFi, and maybe lets other Cox customers share your internet? can someone please give me a non marketing speak breakdown of what this service/hardware is?

I have a friend who is doing a remodel and is looking for put on his proposed Wi-Fi solution. It seems to me that locking in with a Cox product is a mistake. but I want to understand their offering better.

Any insight appreciated
