Hi Nahim,

Current UEFI protocols support only 802.11 WLANs (UEFI spec 2.8, section 27).
I have no idea if anyone tried implementing such a feature in their UEFI FW.

Thanks,
Maciej

Hello,

I would like to know if there is some specification, UEFI protocol or drivers for communicating with WWAN.

Could you please help me with this?

Thank you!
