Technologies are presented for an architecture and infrastructure for a scalable, very high bandwidth, wireless network that can accommodate arbitrarily high geographic concentrations of high-bandwidth users. The architecture may include a network of highly localized service areas that communicate with a central access point through a hierarchy of aggregate-and-relay stages. Communications may be mediated by a hybrid combination of ad-hoc and infrastructure-network features that are supported separately within the framework of a standardized system, for example in the 60 GHz (millimeter-wave) band. The infrastructure may include a dense mesh of fixed control points that communicate over lossy, high-bandwidth, directional channels permitting dense spatial frequency sharing and providing for highly localized coverage, thereby enabling high user densities.
