All in - Galaxy S6 & S6 edge on AT&T carry Samsung "Shannon" LTE modems, Wolfson DACs

The vast majority of 3G/4G-connected devices sold in Western markets from name manufacturers have been relying on Qualcomm chipsets and their integrated multiband LTE modems. The Galaxy S6 and S6 edge make no exception, as most of their versions around global carriers and markets employ Qualcomm basebands. However, Samsung is the first to eschew the application processor, graphics unit, and baseband provided by the US chipset powerhouse in favor of its own solutions, and put its product on sale with a large American carrier. This serves to illustrate the insatiable growth ambitions of Samsung's semiconductor division, which is seeking success beyond supplying flash memory for global clients and making chipsets for the Apple iPhone. The market is due for a shakeup in the next couple of years if Samsung establishes itself as an all-in semiconductor supplier. Recent analyst expectations go as far as suggesting Qualcomm might be looking to adopt Samsung's industry-leading 14nm mobile AP manufacturing process for its own products.
