Are there any routerboards that are suitable to host high speed LTE Cat 4-6 cards i.e. can cope with 150-300Mbps ? The plan is to put together a fast fail-over solution for a customer that's running a CCR.

Thanks in advance!

We currently do not support any Cat6 cards, but many Cat4 work in any RouterBOARD model with miniPCIe slot and SIM slot (like the RB922).

That sounds promising. A couple of more questions if you don't mind:

1. Does the RB912 in the BaseBox offer the same capabilities or is it possible to put a RB922 in an empty BaseBox shell (if available)?
2. Will any of the Cat-4 cards work with direct-ip (preferable using the LTE interface) and without internal NAT?

You can use the Basebox out of the box:

As you see, it has a SIM slot

Excellent, that was actually the solution I preferred. Any tips about where you can find info regarding which Cat-4 cards that supports direct-ip?
