I understand that a WiFi LAN is one.

  Every port on a switch is one.

    https://en.wikipedia.org/wiki/Collision_domain https://en.wikipedia.org/wiki/Collision_domain > By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half-duplex links), or the possibility of collisions is eliminated entirely in the case of full-duplex links. For Gigabit Ethernet and faster, no hubs or repeaters exist and all devices require full-duplex links.

      "or the possibility of collisions is eliminated entirely in the case of full-duplex links." So is a wifi connection full or half duplex? I don't think you understand collision domains.
