You might look at using a low power spread spectrum 900Mhz radio, less interference, no frequency coordination with FCC required and line of sight is surprisingly good, of course you would need same type of radios on the rover end.

You can remove the questions of latency and radio range from this discussion if you use the cellular network for accessing a solution. ?ÿThis is assuming you have decent cellular coverage in your territory.
There are a number of freeware solutions out there but Bench Mark equipment offers a service called Stormcaster that allows you to do this. ?ÿSee this short video for an overview.

Agree about the solving the range (but still have some ppm issues, unless on a large plain with homogeneous atmospheric conditions) but my experience suggests the opposite about cellular comms. latency. Even in the middle of the best patch of cell coverage seems to have more latency issues than base/rover over RTK.

Radio always at the 1 second level (if you can get a connection that is ; <5km ideal conditions, more like <2km in urban/forest environment using 1w satel) whereas cell can often be 2-3 seconds which isn't always a deal breaker for RTK but can slow up your fixes if going in and out of lock.

That's been my experience too, but I think 5G will ultimately swing the pendulum the opposite way.

We have tried Stormcaster and offer these caveats:
1. Make sure that you use it on a base that is static.?ÿ It, in our experience, does not like being set up with a base that is mobile (ie. we tried to use it to set up a site local RTN; it was not a good experience).
2. Make sure to use it with newer equipment.?ÿ We tried using it with Hemisphere S320's.?ÿ It was not a good combo.
?ÿ
That being said, Hemisphere has a company down in the Caribbean who loves it.?ÿ He has a S321 base and cell coverage over the entire island.?ÿ He loves that his base is at home (ie. less chance of theft) and that his RTN costs are about 1/2 what they would be if he were using one of the commercial RTN's.

Another option to consider is Emlid's free NTRIP software:

?ÿ
5 bases and 10 rovers is nothing to poo-poo if you're just starting out.?ÿ Plus, they make using the legacy messages (ie. 1000-1013) easier than most of the discount brands.?ÿ Not sure if they allow UHF and cell at the same time.
?ÿ
If you value your time, it may be better to go with something from igage (ie. a user/seller who has experience doing exactly what you want to do).?ÿ The initial hardware cost upfront may be more, but his experience may save on implementation/troubleshooting time.
