I thought this is where mesh solution shines.
Just need one data point, and you can deploy many wireless routers, interconnected wirelessly via mesh network.
For houses with many data points in living room/bed rooms, these is no need to use mesh network.
They are two types of backhaul with mesh solution.
1) wireless backhaul: mesh nodes need to have good connection to the main node
1a) Dual band mesh with wireless backhaul, you can call this glorified repeater with better roaming support. But performance may not be good for wireless clients to the mesh node.
1b) triband mesh with wireless backhaul. This helps to help the bandwidth the issue in 1a. But the connection between mesh node and main node still post challenges to the placement. Price is higher.
2) Ethernet backhaul
You can call this glorified AP, with easier roaming support (eg: 802.11 k/v/r or proprietary protocol), at least for layman. Even low end dual band AC1200 mesh may have pretty good performance in this case. Example will be the S$79 a pair TP-Link Deco M4 (usual price S$99 per pair, promotion price at S$79 or $89 per pair).
For more experienced users, indeed you can deploy AP in this case and tune TX power or things like that for roaming, but this is not friendly to novice users.
