Apple’s latest wireless chips, the C1X and N1, quietly shift the future of the iPhone and Apple’s control over it. Built into the newly unveiled iPhone Air, these custom chips don’t just boost wireless performance, they make Apple’s tight hardware ecosystem even tighter.
Apple’s wireless chips power the iPhone Air redesign

The iPhone Air’s ultra-slim profile didn’t happen by chance. It’s thanks in large part to the power efficiency of the C1X modem. Apple claims it delivers sub-6GHz 5G and LTE that’s up to twice as fast as its predecessor, all while sipping 30% less energy. Compared to the Qualcomm modem in the iPhone 16 Pro, Apple says the C1X still wins on performance for the same networks.
That’s a quiet but sharp move. Lower power means smaller batteries. Smaller batteries mean thinner phones. This is how Apple slips in a major redesign without sacrificing speed or battery life.
N1 chip steps in to handle next-gen wireless
Where the older C1 handled both cellular and Wi-Fi, the new N1 offloads the latter. It supports Wi-Fi 7, Bluetooth 6, and even Thread a protocol aimed at smart home devices. The shift means better accessory support and less strain on any single chip.
Together, the N1 and C1X lay the wireless groundwork for the A19 Pro to shine. Apple’s new silicon packs a 6-core CPU, 5-core GPU, and a 16-core Neural Engine. Even with its slim build, the iPhone Air isn’t pulling punches.
Why Apple’s wireless chips matter more than specs
This isn’t just about speed, it’s about control. Apple’s been marching toward full hardware independence for years. Ditching Qualcomm modems moves that vision forward. More than cost-saving, it lets Apple build exactly what it needs and cut anything it doesn’t.
Here’s what the new chips enable:
- Faster and more efficient 5G
- Support for Wi-Fi 7 and Bluetooth 6
- Smart home control via Thread
- Lower power draw for smaller battery builds
- A cleaner internal architecture
Apple’s wireless chips are just the start
Apple’s long-term bet is one chip to rule them all. A single processor that handles both wireless and computing is likely coming, but not yet. For now, the separation between the modem and the brain gives it flexibility. And frankly, a competitive edge.
The iPhone Air doesn’t scream “breakthrough” at first glance. But under the hood? It’s Apple showing its cards. The glue between all your devices is going custom.
