Which DW5809e part number for M6800 — 0453K0 or 0K2W44?

[Zazula]

Couldn't find any solid info on that online, asked at the Dell forums but to no avail, so here goes:

I have a Precision M6800 that did not come with a WWAN but I want to add one to it. Minimum cellular networks compatibility should be the EMEA region, but the wider (i.e., the more comprehensive) the better. Anyhow, I said to myself okay let's get DW5809e for this mission, but from what I see it comes under (at least) two discreet Dell p/n's: namely, 0453K0 and 0K2W44. So, what's the difference between those two, and which one should I choose?

Thank you very much in advance! 😊

the difference appears to be their SKU's from Sierra who are the card manufacturer. the SKU is the seven digit number that is on the same line as the model name:

 

0453K0

0K2W44

the warranty checker on the Semtech\Sierra Wireless website is a great way to see the differences between two modules: https://csm.semtech.com/WarrantyChecker.aspx inputting the IMEI of the two modules i've posted above shows that they are in fact the same SKU despite what the label on the 0453K0 shows:

 

 

this in addition to these posts on the Sierra Wireless forums:

lead me to believe that there is no difference between the hardware of the p/n's that you posted.

 

you could also check out using the EM7455(DW5811e) in the M6800:

to be more exact - not EM7455 (this is the m2 version), but MC7455 (this is the minipcie version).

also there are no special limitation for wwan port in m6800/m4800 and you can use other modems in minipcie format.
