I guess that's true that to communicate from a remote to a corporate office, or between two corporate offices, or even between two mobile stations ... as long as you don't need to call a number on the PSTN or communication with Internet services other than what your company or organization provides, then no backhaul would be needed. In a way it's like two ham stations with multiple microphones on either end, or in this case telephones and/or computers. As long as you don't consider the satellites in space as part of the infrastructure then this works. Of course it's doubtful that anything would happen typically to satellites in space (unless your name is Globalstar) Also as long as any infrastructure remains up that allows calls to the PSTN and connectivity to the Internet at the LES then that stuff is fine as well. I guess typically if something weather related happened it would affect only one area of the world. I believe that some satellite systems have more than one LES - which would give you the capability to switch to an alternate and keep on communicating. Anyway thanks again for the comments. --- alan spicer - ka4udx Hi Grady, thanks for the comment.

The military use this but also business with corporate offices all over the world. The way it’s done with as little backhaul as possible is, private static IP’s. In this way, as long as the satellite and the earth station (SAS) have power, you can communicate via voice or data from sat terminal to sat terminal without ever going to the internet or phone lines. In fact, that is the requirement when these folks come in is “we want to communicate in the event that there is NO internet and NO phone lines anywhere in the world”. Of course, I wouldn’t mind having a MSR8000 HF transceiver with a wideband antenna either. The Backhaul issues do come up time to time in the satellite world.
