ICTP’s T/ICT4D Laboratory is divided into two units: Ionospheric Radiopropagation and Wireless Communications Research and Development.

Aeronomy is an interdisciplinary field of science that deals with the physics and chemistry of the upper atmosphere of the Earth and other planets under the effects of magnetic fields and electromagnetic and corpuscular radiation from space.

The scientists at T/ICT4D Ionospheric Radiopropagation Unit study and develop 3D and time dependent global electron density models in the ionosphere. One of these is the NeQuick model that has been developed in collaboration with the University of Graz, Austria. This model is widely used internationally for scientific purposes and also to determine ionospheric effects on satellite navigation and positioning systems (GNSS).

Other research topics of the Ionospheric Radiopropagation Unit are:

  • Ionospheric data ingestion into electron density models to produce 3D specification of the ionosphere.
  • GNSS radio-occultation data inversion to obtain electron density profiles in the ionosphere.
  • Analysis of ionospheric data of different sources and model validation.


    Wireless Communications

    The Wireless Communications Laboratory develops wireless solutions for academic institutions in developing countries. They organize training activities, manage projects and carry out research to find the best solutions to bridge the digital divide.


    • Training: Since 1995, the Wireless Communications Laboratory has held some 40 training activities attracting more than 1600 participants from all over the world.
    • Project management: We have managed projects to connect universities and medical centres in Malawi, to connect environmental sensors in the Venice lagoon and to set up very long wireless links.
    • Dissemination: We participated in the writing of "Wireless Networking in the Developing World". This freely downloadable book is available in English, French, Spanish, Portuguese and Arabic.

      Our main interest is in ICT4D: how to use information and communication technologies to help development of academic networks. In particular, we have been working on:wireless

      • Long Distance Wireless Links: In collaboration with ESLARED (La Fundación Escuela Latinoamericana de Redes) in Venezuela.
      • Wireless Sensor Networks for Development: We are focusing out research on the application of this technology in development projects.
      • Low-cost solutions for wireless links setup.
