Apple’s New Wireless Chips Tighten Its Grip On The iPhone

Apple used the launch of the iPhone Air to debut two in-house wireless chips — the C1X modem and N1 wireless processor — a move that signals its long-term plan to control every major component inside the iPhone.

The C1X modem handles sub-6GHz 5G and 4G LTE, doubling the performance of the C1 modem first seen in the iPhone 16e. Apple says it delivers those gains while drawing 30% less power — critical for the iPhone Air, which runs on a slimmer battery than other models. The company also made a pointed comparison: the C1X is faster than the Qualcomm modem inside last year’s iPhone 16 Pro, at least for equivalent cellular standards.

The N1 chip takes over Wi-Fi duties and adds Wi-Fi 7, Bluetooth 6 and Thread for smart-home accessories. Together, the C1X and N1 pair with the new A19 Pro processor. Instead of a raw spec string, the A19 Pro brings more CPU and GPU headroom alongside a larger Neural Engine — enough to put pro-class power into Apple’s thinnest handset yet.

Beyond this year’s redesign, the chips show Apple’s steady push away from external suppliers. Reports last year suggested the company’s ultimate aim is a single combined modem-processor, though that’s still some way off. For now, the iPhone Air illustrates the trade-off: thinner design, more wireless range, and less reliance on anyone else’s silicon.
