Apple has introduced its first custom-designed modem chip, a move aimed at reducing the company's dependence on Qualcomm chips.
The recently launched iPhone 16e, which is priced at $599, is the first device to feature this chip. This modem chip is expected to roll out across Apple's product lineup in the coming years.
Apple’s modem chip
The modem chip is part of Apple's new C1 subsystem, which combines key components like processors and memory.
As per Apple executives, the C1 system enables the iPhone 16e to have the best battery life among its 6.1-inch phones, due to its advanced processor and modem technologies.
Apple's senior vice president of hardware technologies, Johny Srouji, noted the company is focused on creating a platform for generations, rather than just a single product.
The C1 subsystem is built using advanced 4-nanometre and 7-nanometre chipmaking technologies, ensuring global compatibility with 180 carriers across 55 countries.
While the C1 chips also offer advanced features like custom GPS systems and satellite connectivity, they initially lack support for millimetre-wave 5G networks, a technology where Qualcomm holds a strong position.
Previously, Apple used to source modems from Qualcomm, the world's biggest supplier of chips.
It’s worth noting that developing modem chips is a complex task, requiring compatibility with hundreds of carriers worldwide.
Notably, only a few companies, including Samsung Electronics, MediaTek, and Huawei Technologies, have successfully created their custom modem chips.
