Apple’s N1 Chip Has a Major Wi-Fi 7 Limitation

Apple’s in-house N1 network chip does not support the 320 MHz bandwidth that Wi‑Fi 7 enables, meaning the chip’s maximum channel width remains at 160 MHz and there is no immediate leap in wireless throughput. The article notes that Wi‑Fi 7’s 320 MHz channels promise higher throughput, lower latency, and better performance in congested environments, but the N1’s limitation constrains these gains.

Regulatory filings reviewed by according to MacRumors indicate that the iPhone 17 Pro Max supports Wi‑Fi standards 802.11a/ax/be with bandwidths of 20/40/80/160 MHz. Apple’s launch messaging emphasised the debut of its self‑designed N1 chip, which is intended to replace Broadcom’s wireless solutions that Apple had long relied upon for Bluetooth and Wi‑Fi functionality, though detailed specifications were not disclosed.

While adopting its own silicon could improve inter‑device connectivity and stability across Apple’s ecosystem, the article suggests the shift does not yield an immediate performance upgrade in Wi‑Fi.
