Project FDI 01: Wireless IP Multimedia Multicast

Project Abstract: The objective of this project is to develop an asymmetric wireless bidirectional transmission infrastructure operating with IP technology. The specific application to be implemented is to distribute videos on demand with educational content to high schools (video service and cache). The system operates with two or more distribution centers and approximately 60 reception points (high schools) in Chile’s Fifth (Valparaíso) and Ninth (Temuco) Region. Wireless transmission was chosen because other access technology alternatives, like fiber optic, cable modem and xDSL access technology are expensive for public and private high schools in a country like Chile. In contrast, the broadband wireless access in the non-licensed S band (2,5 GHz range), although requiring some initial investment, has a low operational cost and it is easy to scale.

Expected Results: Video distribution to high schools. This material will also be placed on a web site in low resolution, to be downloaded with narrowband POTS modem technology, alongside with guidelines, for teachers to be able to select and prepare their lecture material. Once a video has been selected by a teacher, he/she may request its transmission in a time frame of the day of his/her choice for classroom use. This web site will also facilitate teacher interaction, presentation of the transmission schedule, provide a list of the most used videos, etc. In parallel to this service an evaluation system will be designed to measure the impact of this system in schools.

Main Impacts:

Social and Economic: To be able to develop a scalable community based wireless IP network. Although in this particular implementation the idea is to use this network to bring information technology to high schools and incorporate it in to their curricula, the application can be easily extended to other interest communities: firefighters, city councils, hospitals and clinics, etc.  For High School teachers this will be a new way to use video information to enrich their teaching activity.

Science and Technology: Research in radio link design in the 2,5 GHz S Band in a geographically difficult area like Valparaíso (many hills that force to build a wireless backbone network) and tuning of application layer software will be necessary to implement the desired video distribution. Also, the capacity of LANs with wireless backbone networks using Linux proxies at High Schools.

Institutional: 1) High speed video for High Schools; 2) Internet access for High Schools and, 3) Use of Information Technology to aid the teacher in the classroom through the implementation of a specific project.
