Abstract :
Three aspects of a new minimum cost, high reliability system strategy for the Hokkaido Integrated Telecommunication (HIT) network, in which real time operation is not demanded, are examined. These are: (1) a packet communication ultra-small aperture terminal (PC-USAT) system, which contains a method for overcoming the satellite link´s rain attenuation discontinuities; (2) an optimum rain margin technique and the 14/12-GHz band rain, snow attenuation, and site diversity (SD) experiments; and (3) a low-bit-rate medical information and still picture simultaneous transmission system
