Apple Unveils Its First Custom-Designed Modem
Apple has introduced its first modem, specifically designed for its devices to enable iPhones to connect to wireless data networks. This move reduces Apple’s reliance on Qualcomm chips, which also power competing Android devices.
This modem will be at the core of the iPhone 16e, which Apple unveiled on Wednesday for $599.
Apple executives stated that these chips will be deployed across its product lineup in the coming years, but they did not provide specific timing details.
These modems are part of a new set of components that Apple calls the C1 sub-system, which also includes key elements such as processors and memory.
Kayan Drance, Apple’s Vice President of iPhone Product Marketing, said that the iPhone 16e, featuring the same A18 chip as the rest of the iPhone 16 lineup, will have the best battery life ever for a 6.1-inch iPhone, thanks to the C1 system.
A Technological Challenge and Reduced Dependence on Qualcomm
Building modem chips is challenging because they must be compatible with hundreds of carriers across dozens of countries.
Only a few companies—Samsung Electronics, MediaTek, and Huawei Technologies—have successfully developed their own modems.
For years, Apple has relied on Qualcomm, the world’s largest chip supplier. Qualcomm’s modems also power Android smartphones and Windows-based laptops that compete with Apple devices.
A New Platform with Global Compatibility
Johnny Srouji, Apple’s Vice President of Hardware Technologies, said that the C1 sub-system is among the most complex technologies Apple has ever built.
The baseband modem is manufactured using 4-nanometer technology, while the transceiver module is produced with a 7-nanometer process.
The chips have undergone testing with 180 telecom carriers across 55 countries to ensure compatibility with all regions where Apple sells iPhones.
Srouji stated:
“We are building a platform for future generations. C1 is just the beginning, and we will continue refining this technology with each new iteration. It will become a true differentiator for our products.”
Apple aims to make the C1 chip a defining feature of its iPhones by integrating it tightly with its processors.
The C1 chip also includes dedicated GPS capabilities and satellite connectivity, allowing iPhone users to stay connected even when outside cellular network coverage.
However, this initial version will not support 5G networks.
