In this paper we consider several issues regarding the use of aHigh Altitude Platform (HAP) as a mobile communications basestation for the UMTS standard. We refer in particular to a solarpowered unmanned stratospheric platform named Heliplat, which iscurrently being designed at Politecnico di Torino within theHeliNet project funded by the European Community as part of theFifth Framework Programme. Here we present a feasibility study ofthe use of the Heliplat platform as a UMTS base station within anintegrated terrestrial-stratospheric UMTS cellular system. Wetake into account the power consumption and the weight constraintimposed by the platform technology, the interference required fora proper system operation and the requirement of maintaining fullcompatibility with the UMTS standard.
