So far, Qualcomm’s solution has been used.
Apple is taking over the development of more and more hardware components, even though manufacturing is usually done by partner companies. With the A15 chipset (and its predecessors), this has been the case for a long time, and the M1 processor in the MacBooks and iPad Pro is also in line, and now the modem is on the table. So far, Apple has used the Qualcomm X60 modem, and this is the case with the current iPhone 13.
However, it has been confirmed from several sources that Apple will start producing its own 5G solution on TSMC’s 4nm node in the near future, so it could already work on the next iPhone (as well as tablets). Since 2018, opportunities have been sought to replace Qualcomm’s solution, and patent disputes and litigation have been ongoing since then.
After Apple acquired Intel’s smartphone modem business for $ 1 billion in 2019 and opened a development center in Munich, it was only a matter of time before they would come up with their own solution, as when the Intel business was acquired, the team expanded by 2,200 on paper and 17,000 patents related to mobile data have also migrated to Apple, as Intel plans to compete with Qualcom in the mobile modem market. We can be sure that if you’re already using a proprietary solution on your next iPhone, they won’t forget to avoid it when announcing the product, most likely underlining the benefits of Apple’s solution with all sorts of numbers and measurement results.
