WWAN and DMC connectors on a laptop, for which equipment?

Question

laptops

When opening (additional installation of memory), two empty seats were found in the laptop (with divorced antennas!) With the signatures WWAN and DMC.
If the first one seems to be for a 3G modem, then the second one I can’t understand why, the only clue is that the driver kit on the site contains a driver for a WiMAX board, what is DMC like?
And, if I understand correctly, WWAN is supposed to be set to something like:
* Dell Wireless™ 5630 (Gobi™ 3000) Multimode HSPA-EVDO Mini Card with A-GPS
* Dell Wireless™ 5550 Single Mode HSPA Mini Card with
Are there any alternatives to the A-GPS function , or if I want 3G Internet, will I have to buy one of these and “no options”?
If anything, laptop Dell Latitude E5520.
Thank you in advance.

Answer 1

If you gave the name of the modem models from the so-called white-list, then they must be set. And you need to check which bios your sheet is for and which one is in your laptop. Judging by lenovo, from version to version, the number of modems decreases, and there, in order to install other modems, people change to a custom version.
DMC - possibly short for Dimension Card? :) Perhaps you can insert a msata ssd disk into it (I accidentally bought one like that).
Purely speculation, I do not pretend to be truthful! :beer:

Answer 2

Display MiniCard ( 1 , 2 ) - for wireless monitors
(transmitting a display image from a graphics card via the built-in DisplayPort and sending a compressed H.264 and encrypted HDCP 2.0 data stream ...)
I don't know, maybe compatible with miniPCI / mSATA.
