Will look into 3G/4G options. With my own option, Intel platform isn't great for WWAN support in general. Plus all the software cost. Will discuss and give feedback later.

IMHO if we spend cost to get WWAN on this Intel device, why not spending a little bit more to build a Qualcomm SoC version? i.e The new PCBA. Modem is built in into SoC and can improve specs either.

Also as mentioned above, with LTE builtin we need too many SKUs, at lease two, for NA and EU. Moreover certification and RF testing will be a lot more complicated, which also costs......
