At my company we have an arsenal of Trimble GNSS receivers and we have 2 UHF radios that we use for base rover RTK solutions when we need. The radios can be problematic and require a lot of extra setup in the field, so I have been trying to get a setup that has the base connect to a mobile hotspot, broadcasting the RTK solutions, with the Rover(s) also connected to mobile hotspots, receiving the RTK corrections. So far I have not been successful. Does anyone use this type of setup? My vendor says this is possible, but also has suggested we purchase a RTK cellular bridge, which is cost the same or more than the radio. This also does not eliminate setting up a piece of equipment. Any help or suggestions would be greatly appreciated.

Unless you have a receiver with a built in NTRP caster this isn't as easy as you'd think.
What model receivers do you have?
We use that setup in our Javad units.
We are using R10's and R8-4's. The setup is able to act as an NTRIP Caster, I just have yet to get this running.

Do you have a Bridge, or do you use the data collector as a caster? If the later, would you be willing to screen shot your settings and email them to me? Even thought the brand is different, i may be able to figure out something from that.

Yes, the reciever is capable of acting as a caster
The R10 is definitely capable.
There may be other ways but we use the Trimble Streaming Manager software.
The R10 sends the corrections to TSM running on your office PC & the rover or multiple rovers can connect to TSM just as they would to a CORS.
I have not heard of this software but the R10 is definitely capable of acting as a caster if it has an Internet connection.
Ignore your dealer the rtk repeater is not required.
You can either put a sim card in the R10 in which case it will need to have a public IP address. Unless you have a static IP address you will also need to use a dynamic dns service.
If you connect the R10 to the Internet by wifi you will need to set up port forwarding on your router.
If you are not familiar with networking stuff then rhe easiest way is with a sim card and buy a static ip one.
I had a client do this very thing earlier this year. The major hurdle to cover is the internet connection. They used Verizon so the internal modem wasn't used. They ended up using a enterprise grade Mi-Fi, the Novatel SA2100 and we determined that they had to get a static IP address for the Mi-Fi. Verizon does some sneaky routing that breaks dynamic dns.

A lot of GSM/3G/4G services give the router (and caster) a private IP address that is shared with hundreds of other users devices. Impossible to log into from the rover.
I could give more specific advice on how to get a public IP address using cheaper SIm cards but it would only apply to the UK.
