Apple’s latest iPhone 17 lineup and the new iPhone Air come with an all-new N1 chip for wireless connectivity, but the chip falls short of Wi-Fi 7’s maximum speed potential.
According to Federal Communications Commission (FCC) filings reviewed by MacRumors, the N1 chip supports Wi-Fi 7 with channel bandwidth up to 160 MHz, below the 320 MHz maximum offered by the standard.
This means the new iPhones cannot reach Wi-Fi 7’s theoretical top speeds, though Apple says real-world performance is largely unaffected because most internet connections and networks do not fully utilize the higher bandwidth.
The N1 chip powers Wi-Fi 7, Bluetooth 6, and Thread connectivity across the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. While some users hoped the custom Apple chip would enable full 320 MHz support, it remains in line with previous iPhone 16 models that also max out at 160 MHz using Broadcom hardware.
Despite the limitation, Wi-Fi 7 still delivers significant improvements over earlier standards, including faster speeds, lower latency, and more stable connections across 2.4GHz, 5GHz, and 6GHz bands when paired with a compatible router.
Apple says the N1 chip provides other benefits, such as better performance for Personal Hotspot and AirDrop and improved power efficiency, helping to extend battery life. For most customers, the company suggests the bandwidth cap will not affect everyday use.
