In this paper I discuss a portable telephone system design which is aimed to realization of the ultimate communication which means one can telephone at any time, any place, and to any place. The major problems to realize the system are : moderate frequency spectrum, service cost, privacy, the pertinent access method to the portable telephone of which location moves with person travel, radio zone costruction, compatibility with present various mobile systems, and hardware techniques. This paper will give some solution for the above problems. The necessary frequency spectrum would not be so much as we expected because the calculation result indicates only 3〜5 MHz will be required.
