Satellites provide IP-based converged voice, video and data communications access to deployed military forces. However, there are issues related to efficient use of expensive and limited space spectrum. There are overheads associated with the Internet Protocols (IP) and the need to encrypt critical messages. There are time delays in TCP-based flows. Satellite resources are expensive. This seminar describes technologies that address these issues. Improved coding/modulation techniques provide more bits per second per hertz. Adaptive coding/modulation increases effective capacity for channels susceptible to rain fade. Overlapped carriers enable uplink and downlink transmissions to share satellite bandwidth. TDM/TDMA/DAMA technology enables dispersed terminals to share spectrum taking advantage of statistical multiplexing in IP networks. The impact of IP overheads can be reduced, especially for voice traffic, Data traffic can be compressed. The performance of TCP-based transactions can be enhanced. The use of high throughput satellites can, for many applications, reduce bandwidth costs. A case history will illustrate the potential gains from combining these mitigations in a representative TDM/TDMA/DAMA satellite network.
