Why do LCD screens have WWAN, WLAN and WIGIG as an option.

The designation refers to the antenna -- there is different wiring for the different options, and it's routed around the LCD screen.

So does that mean you have to order the screen with the WLAN option in order for the internal wireless card to work correctly?  That does not sound correct.  I must be missing something.    thanks  Bob

Hi bob_m10,

Thanks for posting.

Here is some information you may find helpful:

For an explanation about the different screen types, click on the question mark in the advertisement:

WLAN is the default.  It's that you must order the system with a WiGIG or WWAN antenna if you plan to use such a card -- or the required antenna won't be in the system.

Actually if you look at the quick ships from the latitude 5480 WWAN is the default which I found interesting since most users will want WLAN connectivity.  -Bob

Still confused on this, I understand that this selection designates the type of antenna in the LCD frame. Now  when you say WLAN is default, do you mean that no matter what options I select, lets take WiGIG for example, the included antenna will be compatible with WiGIG but also WLAN?  

Anyone have further information on this? thanks  Bob

There's probably a better way to phrase it, but I think basically the options are that the first one has WWAN only, while the second has both antennas.

Automakers found out years ago that a la carte options add to production cost and decrease quality -- maybe the computer manufacturers will eventually figure this out as well.
