When an m2m /ioT router?

I have several glinet products for his security.
I would like to do a recommendation to the company. I am looking now for a router with m2m port to connect my own lte module (custom) or just including a Lte module Cat. 12 or 16. Since now all the routers you have are cat6 at max. .
I would like that also is mounting at least one port gigabit, sim card slot, and possible to use with outdoor lte antennas.

We will see something like that in a near future?

Now we only use PCIe.

As more higher grade LTE and 5G use m2m so we will use m2m for newer and higher grade products.
