Appendix B • Transportable Gateway (TGW)
82
1037852-0001 Revision A
Services Supported
The TGW supports the following services (some require an
expansion pod for full support):
• Broadband WAN connectivity to corporate and government
intranets
• Secure, private IP networking
• High-speed video streaming
• Multicast data delivery
• Multimedia applications including MPEG-4 video and DVR
capabilities
• VoIP telephony
• Serial protocols including Async, SDLC, X.25
• On-the-move operation
DVB-S2/IPoS with ACM
Advantages
The TGW advantages include the following:
• Optimum transmission efficiency through a combination of
coding and modulation of the outbound channel that can be
configured for each satellite modem
• Continually optimized link performance, particularly during
high rain conditions, through dynamic adjustment of
error-correcting codes and modulation based on signal
quality feedback from satellite modems
• Truly dynamic bandwidth assignment - satellite modems with
no traffic are assigned no resources
• Multiple inroute quality of service options - Committed
Information Rates (CIRs) per active satellite modem or group
of modems
