In this talk, a novel wireless infrastructure will be presented which includes a new stratospheric access & computing layer composed of high altitude platform station (HAPS) constellations positioned in stratosphere in addition to the legacy terrestrial layer and the emerging satellite layer. With its bird's-eye and almost-line-of-sight view of an entire metropolitan area, a HAPS is more than a base station in the air; it is a new architecture paradigm with access, transport, and core network functionalities for integrated connectivity, computing, sensing, positioning, navigation, and surveillance, towards enabling a variety of use-cases in an agile, smart, and sustainable manner for smart cities and societies of the future.
