Final Report Chapter 5 Mid-Term Development Plan communication satellite provides could provide only finite transmission capacity and finite no. of satellite, i.e., there is a limit. For the terrestrial (international) optical fiber cables, there are a program to extend them towards Thailand, China and India. As to the submarine cables that provide a larger transmission capacity MPT has studied to join the SEA-ME-WE5 or AAE1 (Asia Africa Europe1) submarine cable Programs or introduction of new submarine cables for two countries. 5.2.7 Quantitative Plan of Telecommunication Infrastructure Total volume of the communication infrastructures to be provided depends largely upon the number of users to be connected there, logically. However, the utilization means of the Internet is changing very quickly, therefore, the transmitted capacity of communication, in addition to changes in number of users, changes very quickly. Hence, to predict the total volume of the communication infrastructures is very difficult. Therefore, to prepare this Mid-Term Development Program, together with the MPT task force team, the joint assumption which is needed in estimation of the communication infrastructures have been prepared as Tables 5.2-7 through 5.2-9 have been prepared. (1) Total Numbers of Subscribers and Volume of Information to be transmitted The joint assumption assumes that the total number of subscribers of both mobile and fixed telephone (voice) assuming to be 80% of the total population. Table 5.2-7 gives those assumptions. 5-19
