Apple is set to integrate its own Wi-Fi 7 chip into all models of the upcoming iPhone 17 series, marking a significant shift from reliance on third-party suppliers. This development follows the company’s unveiling of the iPhone 16e, which introduced Apple’s first custom-designed modem chip, the C1, signaling a broader strategy to internalize its hardware components.
The iPhone 16e, priced at $599, debuted with the C1 modem, enhancing battery life and integrating advanced AI features. This move away from Qualcomm’s chips indicates Apple’s commitment to developing proprietary technology to differentiate its products further. The C1 modem, produced using advanced 4-nanometer and 7-nanometer technologies, aims to offer improved power efficiency and seamless integration with Apple’s ecosystem.
Analyst Ming-Chi Kuo has provided insights into Apple’s future plans, suggesting that the iPhone 17 lineup will incorporate an Apple-designed Wi-Fi chip supporting Wi-Fi 7 connectivity. This transition is expected to reduce costs and enhance connectivity across Apple devices. Kuo’s analysis indicates that while all iPhone 17 models will feature the in-house Wi-Fi chip, only the iPhone 17 Air model will adopt the C1 modem chip.
Wi-Fi 7 technology promises significant advancements over its predecessors, including the ability to utilize the 2.4GHz, 5GHz, and 6GHz frequency bands simultaneously. This capability is anticipated to enhance data transfer speeds, reduce latency, and improve overall connection stability. According to Qualcomm, Wi-Fi 7 can achieve peak speeds exceeding 40 Gbps, making it up to four times faster than Wi-Fi 6E.
The decision to develop in-house Wi-Fi and modem chips aligns with Apple’s broader strategy to control its hardware-software integration more tightly. By reducing dependence on external suppliers like Broadcom and Qualcomm, Apple aims to optimize performance and efficiency across its devices. This approach mirrors the company’s successful transition to Apple Silicon for its Mac lineup, which has been praised for its performance and energy efficiency.
Despite the advancements, the C1 modem currently lacks support for millimeter-wave 5G, focusing instead on sub-6GHz bands. mmWave 5G offers ultra-high-speed connections but has a very short range, requiring proximity to base stations. Apple’s decision to omit mmWave support may reflect a strategic focus on more widely available 5G bands that offer a balance between speed and coverage.
Qualcomm, which has been a primary supplier of modem chips for Apple’s devices, is expected to see a decline in its share of Apple’s modem business. However, the company maintains a licensing agreement with Apple until at least 2027, ensuring continued collaboration in certain areas. In response to Apple’s shift towards in-house components, Qualcomm has been diversifying its portfolio, expanding into sectors like personal computing and automotive to mitigate potential revenue impacts.
