never afraid to embarrass myself in public, after a discussion with
a colleague, i want to make sure i understand what it is that allows a
router to advertise itself as something like "3G/4G/LTE" compatible.

  i want to purchase an openwrt-supported router that lets me play
with both:

  * a raw USB GPS receiver
  * a 3G/4G broadband modem

my colleague pointed out that, when looking at advertising material,
one needed to look for the "3G/4G" label somewhere. but i had assumed
that, if i'm going to configure, build and install openwrt, i have
control over all the drivers/modules i'm going to install, so i can
simply add whatever software features i'm going to need.

  as in, for GPS, as long as a router has a USB port, i can build
openwrt so that it can talk to a USB GPS receiver i just bought:

  the same for a 3G/4G broadband modem -- all i technically need is a
USB port, and i can build and install openwrt with all of the
functionality i need so i can plug in and use, say, a sierra wireless
modem, no?

  one exception -- a board i'm playing with has a PCIe slot, so
obviously, that's another option for a broadband modem such as, say,

http://www.ebay.ca/itm/Sierra-MC7700-Mini-PCI-e-3G-HSPA-LTE-100MBP-Wireless-WWAN-WLAN-Card-GPS-Unlocked-/111045288092

but other than that, as long as the router i select has a USB port, is
there anything else *physically* about a router that would make it
incapable of what i want to do? am i making sense?
