Abstract :
Discusses measurement and reduction of facsimile communication time in Japanese analog and digital cellular systems. In analog cellular systems, the authors attempted to reduce the facsimile communication time by using an effective combination of 9600 bps facsimile transmission speed and a new fall-back method based on the ITU-T´s error correction mode. Field tests showed the reduction of communication time compared to the conventional transmission method. Transmission errors were recovered sufficiently by the method used. In digital cellular systems, the authors found that the mean communication time was longer in comparison to the mean communication time in analog cellular systems. As for errors, there were none observed
