One problem by replace mPCIe WWAN by mPCIe TV card, will be, to find a mPCIe TV card. In the past, analogue and DVBT cards are used. Now in some countrys are used DVBT-2. I dont know one mPCIe DVBT-2 card. Analogue and DVBT(1) ara available on ebay and so on.
You can buy for a bug a USB DVBT-2 dongle and use on your pc. I can be its possible to connect the USB TV card by usb or by a usb to mPCIe adapter to a mPCIe slot. A it can be, the easy way is to connect the card directly to your notebook or buiild in your notebook by mPCIe to usb adapter. If you are looking for TV for your Handy, TVBT-2 cards for smaller Handy one usb are available on Ebay and so on too.
If you want to figure out some thing with your Mudi, you can look for a better WLAN or a better WWAN and think about is possible to pimp this a little bit or not.
