“…Also, the Gigabit Satellite Project, which plans to offer ATM-based high-speed star or mesh type network services using an onboard ATM switch (155 Mbps to 1.2-1.3 m terminals) and SS-TDMA based point-topoint gigabit connections (1.2-1.5 Gbps to 0.5-1.2 m terminals) using an onboard microwave switch matrix. It will have three scanning and two spot beam antennas, and will operate in the Ku and Ka bands [20,21]. The projected launch for this satellite is 2002.…”

“…(The term "K band" was originally given to the range 18-27 GHz. After a molecular water vapor absorption resonance was discovered at 22.3 GHz, the terms Ku band (12-18 GHz) and Ka band (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) were introduced to denote "under" and "above" K band; however, the regime [20][21][22][23][24][25][26][27][28][29][30] GHz is now in common use for the "Ka band" designation [2]). As there are different frequency breakdowns from the FCC and the IEEE for satellite band letter designations, to avoid possible confusion we will use in this paper the frequency breakdown adopted by the IEEE.…”

Satellites are well suited for broadband communications. In this paper we consider the special features of satellite systems, some of the broadband applications that are well-suited for satellites and some of the technologies which make possible broadband satellite communications, as well as the research programs that led to their development. We describe how such technologies, and other factors, have contributed to the evolution of broadband satellite systems, and discuss some of the challenges in establishing such systems. We finish by offering some concluding remarks on the role of satellites for broadband access.

“…A communication system that can economically accommodate ISDN users in rural areas is strongly needed to expand ISDN service areas. Satellite communication systems are one of the most realistic solutions because they can accommodate ISDN users located far from a service access point by installing an Earth station on the customers' premises [5]. ITU-T recommendation I.571 presents a system model of satellite communication for ISDN services based on the VSAT network [6].…”

This paper presents an advanced satellite communication system named DYANET II. This system uses satellite channels as subscriber lines for ISDN customers as well as trunk circuits for overflow traffic. The system can offer the same ISDN services to satellite customers as those available to terrestrial subscribers in terms of numbering, signaling, and charging systems as well as user-network interfaces. It can also set up satellite channels on a demand assignment basis to achieve efficient satellite channel utilization, and to connect customers by single-hop satellite connections. A compact, lightweight Earth station has been developed for remote customers and temporary demands such as exhibitions.

“…However, since the ISDN infrastructure is not yet matured, an economical means of providing ISDN services to rural areas is greatly needed. Satellite communications is one of the most promising methods of satisfying this need, because ISDN subscribers far from service access points can be easily connected through a compact earth station on the customer's premises [5]. It is also useful to carry overflow traffic from a terrestrial HO (384 kbit/s) and H1 (1536 kbit/s) transit network.…”

system integrated into ISDN called "DYnamic channel Assigning and routing satellite aided digital NETworks II (DYANETII)". DYANETll connects ISDN subscribers and carries overflow trunk traffic by satellite.systems for rapid expansion of ISDN services throughout Japan, it enables satellite subscribers to receive the same ISDN services as terrestrial subscribers in terms of numbering and billing systems as well as user-network interfaces.makes it possible to set up satellite channels on a call-by-call bask for efficient utilization of satellite channels and establish single-hop connections for any type of connection. Moreover, compact earth station equipment has been developed for customer's premises use.This paper describes an advanced satellite communication Since DYANETll is intended to supplement terrestrial The development of advanced network control technologies
