Today with help of our IT guys, I was able to Rube Goldberg together a similar solution as previously reported by Leon. I commented there too, BUT wanted to start a new thread as I had to add a few more pieces of hardware to the mix and a little different way of going about it using mostly gear I already had. This new thread will keep from cluttering up the other one and I can maybe answer specific questions here about my configuration.
Isavi connects to the outside world via the Inmarsat satellite network?ÿ http://www.wideye.com.sg/default/index.php?option=com_content&view=article&id=128&Itemid=11
TP-Link travel router takes that WiFi signal and outputs it on a LAN port?ÿ https://www.tp-link.com/us/products/details/cat-9_TL-WR802N.html
Ethernet cable gets feed into the Intuicom Bridge-X (need to change an internal menu to use Ethernet vs cellular data)
Bridge-X broadcasts the RTN corrections received over the internet connection to my Leica rover over 900 Mhz radio.?ÿ http://www.intuicom.com/gps-gnss-products/rtk-bridge-x
Lots of RF floating around ?
Basically when inside the coverage area of an RTN and there is zero cell phone network coverage, I can break out the satellite connection and continue, no longer will lack of cellular internet be a game changer to an alternative method.
Remains to be seen if this will be cost effective, but for certain tasks I can see it being cost effective in that you can work with an RTN regardless of cell coverage and potentially save a good bit of labor (setting aerial control over a wide area that is "off the cell grid" for instance) with that labor savings hopefully more than offsetting what Inmarset is selling airtime for!
Pretty excited about adding another tool to the box and for me is was a $30 router as the Isavi terminal was already on board the survey truck for phone and e-mail in remote areas as a safety item. We will be out just the actual air time plus the IT guys Friday afternoon (and it was a nice day at the airport).

I have a project in the Pacific Ocean (Marshall Islands), where my client is using a similar Sattelite Phone with WiFi. I can remote into the data controller and upload data or diagnose tech support.
Why do you need to convert the WiFi into Spread Spectrum? Seems too much baggage. Can't you use the?ÿRTN correction via wifi only, as NTRIP correction??ÿ Or get a solution at a single point on the project. Then set up your own local?ÿbase to broadcast the Spread Spectrum signal.

Lee, some of the excess baggage is due to having an older receiver without WiFi, I already owned everything but the router so instead of trying to add WiFi capability on the receiver I used the parts I mostly had. As Leon did with a receiver with on board WiFi, you could just go straight from the satellite hot spot on the terminal into the receiver, within the distance limitations of WiFi. I could also eliminate the router if Intuicom allowed the internet source to be WiFi, but WiFi is only an output of the Bridge-X as far as I can determine. In addition, I have course have a lot longer range with 900 MHz feeding the receiver vs WiFi. All of the extra hardware can be housed at the truck, nothing else extra to add to the pole and field operations are identical at the pole, the extra hardware is transparent once running. Necessity is the mother of invention and without a receiver that will take a WiFi internet connection as the source of the internet input I see this as one way to extend the usefulness of older receivers without trying to to somehow add a WiFi receiver at the pole.
