  • Digital Radio Technology and Applications
    it DIGITAL RADIO TECHNOLOGY AND APPLICATIONS Proceedings of an International Workshop organized by the International Development Research Centre, Volunteers in Technical Assistance, and United Nations University, held in Nairobi, Kenya, 24-26 August 1992 Edited by Harun Baiya (VITA, Kenya) David Balson (IDRC, Canada) Gary Garriott (VITA, USA) 1 1 X 1594 F SN % , IleCl- -.01 INTERNATIONAL DEVELOPMENT RESEARCH CENTRE Ottawa Cairo Dakar Johannesburg Montevideo Nairobi New Delhi 0 Singapore 141 V /IL s 0 /'A- 0 . Preface The International Workshop on Digital Radio Technology and Applications was a milestone event. For the first time, it brought together many of those using low-cost radio systems for development and humanitarian-based computer communications in Africa and Asia, in both terrestrial and satellite environments. Ten years ago the prospect of seeing all these people in one place to share their experiences was only a far-off dream. At that time no one really had a clue whether there would be interest, funding and expertise available to exploit these technologies for relief and development applications. VITA and IDRC are pleased to have been involved in various capacities in these efforts right from the beginning. As mentioned in VITA's welcome at the Workshop, we can all be proud to have participated in a pioneering effort to bring the benefits of modern information and communications technology to those that most need and deserve it. But now the Workshop is history. We hope that the next ten years will take these technologies beyond the realm of experimentation and demonstration into the mainstream of development strategies and programs.
