Overview

• FCC documents reviewed by MacRumors confirm the N1 wireless chip in the iPhone 17 lineup supports Wi‑Fi 7 only up to 160 MHz channel bandwidth.
• Apple’s N1 is used across iPhone 17, 17 Pro, 17 Pro Max, and iPhone Air, integrating Wi‑Fi 7 alongside Bluetooth 6 and Thread.
• Capping bandwidth at 160 MHz excludes Wi‑Fi 7’s 320 MHz mode, limiting peak theoretical throughput versus the standard’s maximum.
• The practical impact is expected to be minimal for most users because ISP speeds, router support, and local conditions usually constrain performance.
• Last year’s iPhone 16 models (except 16e) also topped out at 160 MHz using Broadcom hardware, and expectations that Apple’s in‑house N1 would enable 320 MHz were not borne out.
