Short description This is one of the first books to focus on the emerging HAPS technology that offers a cost effective and easily deployable alternative for terrestrial and satellite line-of-sight propagation paths needed for high capacity wireless services. It gives a thorough overview of the technology including HAPS based communications systems, antennas, propagation and channel modeling, HAPS networks, and finally the future applications.
