Apple's In-House Wireless Chips Transform iPhone 17

Apple's latest partnership with GlobalFoundries isn't just about manufacturing, it's about control. GlobalFoundries announced a deeper collaboration to advance semiconductor technologies and strengthen U.S. manufacturing, with Apple accelerating investments at the Malta, New York facility to build a more resilient onshore supply chain. Here's the real play, Apple is systematically replacing every wireless component in the iPhone with its own silicon, and the implications reach far beyond raw speed.

What this means for the iPhone's future

Apple is expected to transition to in-house chips over the next three years, and Kuo has previously said he expects Apple to equip nearly all of its products with its own Wi-Fi chip on that timeline. That points to a full lineup shift, phones, laptops, watches, everything moving in lockstep.

The C1 modem could reshape how Apple devices connect, echoing what Apple Silicon did for performance and design. The M1 did not just make Macs faster, it enabled the featherweight MacBook Air, and this wireless pivot opens doors to designs and behaviors that off-the-shelf parts would have blocked.

Looking ahead, potential future advancements of the C1 include millimeter-wave 5G. Apple's levels of investment suggest a long-term modem roadmap. The company is ramping up efforts to develop its own wireless connectivity chips, signaling a shift away from suppliers, with gradual rollouts across new devices.

Complete control over wireless connectivity also aligns with ambitions like AR glasses that need seamless hand-off to iPhone or edge compute, and automotive integrations where latency and reliability are safety features, not preferences.

The control game Apple is really playing

Bottom line, Apple's wireless chip strategy is about ecosystem lock-in at the silicon level, not just better iPhones. When Apple controls the modem, Wi-Fi, and Bluetooth, it can build experiences that off-the-shelf parts simply do not allow.

The switch to Apple-designed chips will enhance connectivity across Apple devices and reduce costs. The playbook mirrors Apple Silicon, first hit feature parity, then squeeze out performance with integration, then unlock capabilities competitors cannot match. This is Apple's most comprehensive hardware investment since the iPhone X, aimed at keeping the lead in a crowded market.

The real question is not whether iPhones get better, it is how much deeper users drift into Apple's world once these chips light up. If instantaneous device switching, room-scale AR, and seamless multi-device workflows show up as Apple-only experiences, you start to see the larger story. This is not just about chips. It is about who owns the connection, and Apple is making its move to own it end to end.

Apple's iOS 26 and iPadOS 26 updates are packed with new features, and you can try them before almost everyone else. First, check our list of supported iPhone and iPad models, then follow our step-by-step guide to install the iOS/iPadOS 26 beta — no paid developer account required.
