LAN Design for IP mesh radios

Hi guys, I have a bit of a confusing situation that I'm trying to think of a solution for. So let's say that you have LAN A with a set of devices and LAN B with another set of devices. All devices have static IPs, so that in all the associated software, we know which device has what IP. When both these LANs are put together, you have one 'system'. Each LAN has an Ethernet switch and an IP mesh radio. When the mesh radios are on the same frequency, you effectively join those LANs together wireless so that LAN A can communicate with LAN B.

Now imagine you introduce another 'system', with exactly the same set up. All the same devices, all the same IPs. Now if the frequency of the radios on this second system is different to that of the first system, then you have two independent systems. But the problem comes when the mesh radios on both systems run on the same frequency...IP conflicts EVERYWHERE!

How would you go about avoiding this issue?

I understand that you could have all devices on say 192.168.1.x on System 1 and 192.168.2.x on System 2 but then this would mean reconfiguring the static IPs of all devices and then having to alter the software to match for each specific system. However, I should mention that the mesh radios have their own configurable static IPs - we could change these specific IPs between systems, but would this be enough to prevent conflicts when running multiple systems in this mesh configuration?

I hope that makes sense and thank you in advance!
