Radios for Data Centers

I am looking for some information regarding licensing for a few simplex UHF HTs for my company. We are a data center company. We are looking for radios for our sites in Secaucus NJ and Wall street area in NYC.

Would both sites be covered under the same license, or would they each require their own license?

We don’t necessarily need to talk between sites, however would it be allowed under our license to connect the sites over voip (or roip).

Thanks in advance for your help.
