Fixed broadband wireless access network architecture for on-demand interactive tutorials

Fixed broadband wireless access networks have been widely deployed in school campus for high speed duplex data transmission across an area of several kilometers. Its flexible network architecture makes such network particularly suitable for network access over a number of different locations within a school campus. Support of on-demand tutorial enables students to attend virtual classes at different times within the campus. This work studies the behavior of a typical local multipoint distribution service system providing interactive tutorials by means of playing back a pre-recorded tutorial on a programming exercise over three different locations within an area of 1.5 km radius. Result shows that such system can provide reliable service irrespective of the modulation scheme used.
