Satellite and Terrestrial Communications – Achieving an Integrated Network

To be announced.

Satellite communications networks offer many possibilities and opportunities in bridging the digital divide and extending broadband services to remote sites. This course takes the next step in the process by defining, describing, and resolving critical issues related to making data and multimedia applications work through the geostationary satellite environment. Each day is dedicated to an important area of investigation and set of solutions to current-day and evolving problems that hamper the integration of satellite and terrestrial networks. Technical and operational aspects of interfacing application data from the user to the satellite network are detailed. How to properly employ key standards also is reviewed, such as TCP/IP, Gigabit Ethernet, Digital Video Broadcast, Asynchronous Transfer Mode, and IP Sec.

The course is intended for working satellite communications engineers, systems architects, network designers who wish to interconnect terrestrial and satellite links efficiently, and business people who need to understand the complex issues that stand in front of creating a working user application. Participants should be able to:

· Understand the geostationary satellite environment and how it impacts the operation and performance of present-day terrestrial data, voice, and multimedia networks

· Learn about digital standards unique to the satellite environment that are suitable for transferring data in various formats

· Gain an appreciation for how satellite networks can be made secure and manageable

· Understand the strengths and weaknesses of TCP/IP over satellite links

· Become familiar with specialized satellite access methods and network management techniques to provide end-to-end services on par with terrestrial networks

· Understand the capabilities and relative merits of satellite versus terrestrial networks as well as the means to provide complementary solutions

Since this course addresses the next level of satellite network design, participants should have some familiarity with satellite links. An understanding of the details of earth stations, satellite communications payloads, and user terminals--while helpful--is not a prerequisite. Application areas include data, voice, and digital video networks, and the integration of these in the commercial and government domains.

Coordinator and Lecturer

Bruce Elbert, MSEE, MBA, President, Application Technology Strategy, Inc., Thousand Oaks, California; and Adjunct Professor, College of Engineering, University of Wisconsin, Madison. Mr. Elbert has been involved in the satellite and telecommunications industries for over 30 years and founded ATSI to assist major private and public sector organizations that develop and operate cutting-edge networks using satellite technologies and services. Among his recent projects include providing a full office suite of applications to an ocean-going vessel and the development of a video distribution and data communication network that reaches over 200 locations in the Asia-Pacific Region. During 25 years with Hughes Electronics, he directed the design of several major telecommunications projects, including a multi-beam Ku-band digital broadcasting satellite capable of serving 50 U.S. markets; the management of data communications services to several major corporations using very small aperture terminal (VSAT) facilities; Palapa A, Indonesia's original satellite system composed of 40 earth stations and the associated telephone switching; the Galaxy follow-on system (the largest and most successful satellite TV system in the world); and the development of the first digital processing GEO mobile satellite system capable of serving handheld user terminals. . He has written seven books on telecommunications and IT, including The Satellite Communication Applications Handbook (Artech House, 1997); The Satellite Communication Ground Segment and Earth Station Handbook (Artech House, 2001); and Introduction to Satellite Communication, Second Edition (Artech House, 1999).

Lecturer

D.C. Palter, BSME, MBA, Vice President, Mentat Inc., Los Angeles, CA. Mr. Palter is responsible for licensing TCP/IP and other networking protocol stacks to computer manufacturers and TCP/IP link acceleration technology to the satellite industry. He is a frequent speaker on Internet over Satellite at industry events and has contributed articles on TCP/IP performance enhancement techniques to numerous satellite, networking and telecommunications publications. Prior to joining Mentat in 1995, Mr. Palter was with the Asia Pacific office of Hughes Electronics. He was previously a research engineer in computational fluid dynamics of combusting flows at Kobe Steel in Japan and a designer of emergency power units for Allied Signal in Los Angeles, California. Mr. Palter is the author of Satellites and the Internet--Challenges and Solutions (SatNews Publishers, 2003) and Kinki Japanese (Tuttle, 1995), a textbook on the Osaka dialect of Japanese.
