4G solutions with cisco products

This is with a 3G card, but I would guess that 4G is going to be very similar.

Personally, unless I knew for sure that the router was going to be located in a closet with good cell reception, I would prefer to use an external cell card solution. For example, I've used a usb cell card with a cradlepoint adapter which provides Ethernet hand-off from the cell card. With this hardware I'm now allowed to move the antenna/cell card anywhere in the building that has an Ethernet cable and I don't need to use any special external antennas or signal-degrading antenna extension cables.

Now, even though my preference is unlike the config example I posted, the site that uses the HWIC-3G-CDMA-V works great. Regardless of hardware choice, once the interface is setup the rest of the config is normal routing with the addition of increased round-trip latency.
