  14. Future Plans for the Satellite Mobile Communications Services • Maritime Satellite Communications Services • - Maintain the satellite communications services for the • maritime customers who have no other methods to • communicate. • - Improve the satellite communications services such as • connecting Internet or data transmissions. • 2. High reliable communications network • using 2 Satellites • - Keep the good satellite communications network • performance with high reliability even in the disaster. • - Data transmission usage in the area where the terrestrial • mobile services don’t cover. Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002

  15. Future Plans for the Satellite Mobile Communications Services 3. Integrated services for the next stage after launch of higher performance satellites. - High speed satellite communications services using S-Band and provide new services in the broadband satellite network connecting to IP Network. - Small size satellite terminals for easily portable use.
