the core modem design is 40 x 29.8mm in size, but that of course excludes things like the sim card reader, or any other new components we may add.
So it looks like the MiniPCI Express Card on this picture http://en.wikipedia.org/wiki/File:MiniPCI_and_MiniPCI_Express_cards.jpg ?
I was thinking of a full-size PCIe connector like in desktop PC use. This allows the modems to be 90degree angle from the main board. The miniPCIe or miniPCI connectors require the modem to be flat on top of the base board, reducing the density and increasing PCB size of that backplane.
Do you mean the x16 with full-size PCIe?
Size/Pins:
PCI Express ×1 - 25mm - 36 pins PCI Express ×4 - 39mm - 64 pins PCI Express ×8 - 56mm - 98 pins PCI Express ×16 - 89mm - 164 pins

Do you have done some pinout done? The x16 (full size) is a really huge as connector.
I think the initial hurdle to get it run on the table is really high with this kind of connector.
Well, we can always make a simple PCIe break-out board that you can plug the modem into. That break-out could then provide you with a 2.54mm pitch standard header. Would that work?
Sounds good.
