High-Altitude Platforms for Wireless Communications (eBook)

Dr. Aragón-Zavala graduated from Tecnológico de Monterrey, Campus Querétaro as Electronics and Communications Engineer in December 1991. In 1998 he received his MSc in Satellite Communication Engineering from the University of Surrey, and in 2003 his PhD in Antennas and Propagation at the same university. He has worked as an engineer and consultant in the industry, and since 2003, Dr. Aragón-Zavala is the Academic Director of the former IEC and ISE undergraduate programs at the Tecnológico de Monterrey Campus Querétaro, and is in charge of ITE (all Electronic Engineering degrees). His research interests include: mobile communications, satellite systems, high-altitude platform systems, antenna design and indoor propagation. Dr José Luis Cuevas-Ruiz received his PhD from Universitat Politecnica de Catalunya in 2005, where he was involved in the HeliNet and CAPANINA projects related to high-altitude platform systems. His research interests include HAPS, wireless communications and channel modelling. He has been with Tecnológico de Monterrey Campus Estado de México since 1999, and currently he is Head of the Communications Research group at Campus Estado de México. Dr José Antonio Delgado-Penin is a full professor at the Department of Signal Theory and Communications, at Universitat Politécnica de Catalunya, Spain since 1984. His Academic, technical and research activities have been at Philips N.V, ETSITM, Polito, CNET, Univ. Manchester and UCLA amongst others, all in the field of Telecommunications engineering.
