with all due respect, YOU'RE NOT LISTENING !!! Doesn't matter what the VSAT bandwidth is, whether 28k, 56k, 512k, etc ... It's the LATENCY
Say you're gonna copy a LARGE file on a high bandwidth VSAT with proper acceleration ( minimizes the packet handshaking, uses large windows ) ... It will still copy at almost the full bandwidth speed, BUT it won't actually start for a second or so after you hit send ... No big deal, like clicking on a web page, adding a second to the response to get the next page, but once it comes in, it comes in fast ... BUT for RDP/terminal server, you don't see your keypress until that roundtrip takes place ( up to a second ) because you're seeing the effect on the screen/form on the remote Terminal Server, not on your local system. So if you're a good typist, you can type blindly and hope it all is correct. But if you have to back space or position the cursor, you have to wait a second to see it move to where you want it... Same for tabbing from field to field in a data entry screen ... You can take my word for it, or you can try it and pull out your own hair ...

One company offers "CIR is $5/per Kbps", so an extra $150 per month for 30Kbps? I wonder if that would work for RDP. Or maybe something like this http://www.mobilsat.com/satellite-VPNVirtualprivatenetworking/ could be used? I need to call them and find out. Or maybe we need to move away from Terminal Server and go with something else. I am liking the idea of peersync for data files, and a web based application for our main app. Gene Giannamore Abide International Inc.

You're NOT gonna like RDP over VSAT. VSAT is high latency, minimum 600ms or more as you have to roundtrip 100,000 miles to see the result of a keypress ( sync satellites are 23,000 to 26,000 miles up in orbit ) I used to work for a retail operation with VSAT, and we ended up putting in DSL also for Terminal Server access to payroll applications as they were simply painful to use over satellite. Do you have any cell coverage at all at the site ? Better off with EVDO or even connection to cellphone as a modem Erik Goldoff IT Consultant Systems, Networks, & Security -----Original Message----- From: Gene Giannamore [mailto:[email protected]] Sent: Friday, May 29, 2009 6:01 PM To: NT System Admin Issues Subject: Mobile Satellite for Internet access We have a need for a semi-mobile satellite setup at a remote construction site. Basically because of theft, we need to lock up the equipment at night (even then it might get stolen). So we hope we can find some equipment we can setup each day for internet access, mainly to access our terminal server via RDP. Maybe put it on a cart along with a wireless router, or plug the Ethernet cable into the trailer (if we can wire the trailer). I have found several companies that provide this service. Wondering about people's experience with this. Thx. Gene Giannamore Abide International Inc.
