I’ll have to disagree on that one, WiFi extenders extend an existing network, keeping the same network and DHCP is done by the original access point.
A hotspot creates a new network, and DHCP is handled by the hotspot, not the network on the WAN side.
A friend of mine was very enthusiastic about this as well, he actually planned an entire trip around visiting the Schwebebahn. From his account it’s truly as wicked as it looks, and very stable as well.
