After many rumors about the technology that Apple will use to provide its iPhone and 5G technology, it seems likely. The company will eventually use its own antenna design, mainly because they are dissatisfied with what Qualcomm offers them. You will use your chip, but the antenna will be built at Carlertino.
5G connectivity is the future. Although the operators, and to a lesser extent some manufacturers, want to make us believe that they already exist, the reality is that infrastructure is far from providing real 5G service
Apple looks likely to take over this year, with the launch of the iPhone later this summer. And it looks like he'll do that by combining Qualcomm's technology with his own. On the other hand it will use a Qualcomm chip, but depending on the antenna it will use its own architecture. The reason for this decision lies in the design of the iPhone. According to company sources, the Qualcomm antenna will not fit the design that Apple wants to give its next iPhone.
This is a real challenge for Apple, since combining the various different technologies for such an important component is never an easy task. For that reason Apple maintains a separate, stationary design, in case its antenna design fails, something they don't expect to happen but they admit today they can't get out. In addition the demanding company relies as little as possible on Qualcomm, it is not necessary to recall the dispute between the two companies that ended in the agreement but the ashes are still very hot.
The decision to integrate different technologies will be in the year 2020. Apple's plans include storage using its own 5G chip, which is why they are buying the Intel modem business, but the development of these chips will not arrive, soon, until 2021, so you currently need Qualcomm if you want to use 5G on your iPhone.
