Provides an introduction to High-Altitude Platform Stations(HAPS) technology and its applications for wirelesscommunications
High-altitude platform stations offer a promising new technologythat combines the benefits of terrestrial and satellitecommunication systems for delivering broadband communications tousers at a low cost. They are easily deployable and easy tomaintain, which is why they offer a good alternative for networkoperators who need to find ways to get more coverage to satisfy theincreasing demand for more capacity. HAPS are usually balloons,airships or unmanned aerial systems (UAS) located in thestratosphere. An enormous interest has grown worldwide toexamine their use not only for broadband communications, but alsofor emergency services, navigation, traffic monitoring, cellular,etc.
Key features include:
* Unique book focusing on emerging HAPS technology and itsapplications
* Provides a thorough overview of the technology includingHAPS-based communications systems, antennas for HAPS, radiopropagation and channel modelling issues and HAPS networkingaspects
* Presents various HAPS-related projects and initiativesdeveloped throughout the world (North America, Europe andAsia-Pacific)
* Features a comprehensive overview on both aeronautical andtelecommunications regulatory aspects, which will affect thedeployment and future developments in the field of HAPS
High-Altitude Platform Systems for WirelessCommunications will prove essential reading for postgraduatestudents in the field of HAPS, engineers, developers and designersinvolved in the design and maintenance of HAPS, aerospaceengineers, and communications system planners and researchers.
