For years, rumors have circulated that Apple, in addition to developing its own 5G modem chips, has also been working on proprietary Wi-Fi and Bluetooth solutions to replace those supplied by Broadcom. Traditionally, Apple has relied on Qualcomm for modems and Broadcom for wireless components.
Now, Apple is gradually phasing out Qualcomm’s modems in favor of its in-house C1/C1X 5G chips, while also introducing its own Wi-Fi and Bluetooth silicon—already deployed in the iPhone 17 lineup.
Apple’s custom N1 chip is designed to handle Wi-Fi, Bluetooth, Thread, and other wireless protocols, with the dual aims of delivering superior wireless performance and greater power efficiency. In theory, the N1 should significantly optimize connectivity, and by unifying wireless functions under Apple’s own hardware, strengthen the seamless integration of its ecosystem. This strategic shift underscores Apple’s motivation to replace Broadcom’s solutions with its own.
During the keynote, Apple highlighted the use of the N1 chip in the iPhone Air, but made no mention of it in relation to other iPhone 17 models—leaving it unclear whether the broader lineup has also adopted the new silicon.
The iPhone Air additionally employs the upgraded C1X modem, a successor to the C1. Offering far better performance, the C1X marks Apple’s next step beyond the C1, which had been tested exclusively in the iPhone 16e as a proving ground for refining Apple’s modem technology.
Looking ahead, Apple appears intent on progressively replacing supplier components with fully self-developed chips—not only in modems, Wi-Fi, and Bluetooth, but potentially across an even wider range of functions—signaling the likely end of its long-standing partnerships with both Qualcomm and Broadcom.
