Home mesh is mostly about having wireless backhaul, and you can certainly do that if you have (preferably) two radios, you just set up one radio as a client to your main AP.

Even if you aren't doing wireless backhaul you just rely on regular client behaviour to transition between APs, can enable 802.11r to improve this.

Enterprise "mesh" typically uses wired backhaul for performance and can help clients roam quicker with a controller (auth, not deciding to roam). Controller can also adjusts radio power so APs aren't talking over each other if they're too close.

Mesh isn't any magic, just regular wifi.
