A metro-scale WiFi is the talk of the town and the dream of the future. Currently meshes are the answer to large scale WiFi networks but meshes may not be able to provide enough capacity for multiple classes of users and multiple applications on the same infrastructure. To combat this problem the mesh vendors are adding additional radios to their system. This could be the solution to several problems with mesh technology and may lead WiFi into an entirely new direction.
