Apple faces challenges in its endeavour to create an in-house modem chip for the iPhone, with reports suggesting a potential delay in its launch.
The company, aiming to match the performance of Qualcomm components, may miss its initial target of shipping the chip by the spring of 2025, according to anonymous sources.
The modem project, codenamed Sinope, is tasked with designing a chip that can seamlessly connect to diverse cellular networks globally, competing with Qualcomm’s established technology.
Apple’s modem project, initiated in 2018 with thousands of employees involved, encounters the formidable task of designing a chip capable of connecting to hundreds of cellular networks under varying conditions. The complexity involves surpassing Qualcomm’s technology, a leader in the field for years. The company’s goal to create a modem that downloads data faster than current technology faces hurdles in the development process.

Project Status and Qualcomm’s Continuous Involvement
Public awareness of the modem project challenges emerged in September, just before the iPhone 15 launch. Qualcomm’s announcement of continued chip supply to Apple indicated that the in-house efforts were facing difficulties. The extension of the relationship between Apple and Qualcomm, initially set to end in 2024, was extended to 2026. The firm’s attempt to build its own technology had fallen short, leading to the extension of its reliance on Qualcomm.
The journey to develop its modem began more than five years ago when Apple started hiring engineers in Qualcomm’s home base of San Diego. Despite legal disputes over modem royalties, the companies settled in 2019, with Qualcomm providing 5G modem chips for the iPhone 12. however, the company expressed its intent to replace Qualcomm eventually and acquired Intel’s modem division for $1 billion.
Strategic Moves and Target for Modem Integration
Apple, led by Johny Srouji, hired hundreds of wireless technology experts to support the former Intel engineers. Initially aiming for a 2024 release, Apple envisioned the first device with the in-house modem to be an update to the iPhone SE, a more affordable model that receives regular updates. The choice aimed to ensure safety in introducing a new chip while avoiding potential issues that could impact core functionalities.
While the development of an in-house modem chip signifies Apple’s desire for greater control over its hardware components, the critical nature of the modem in a phone is acknowledged. A faulty modem could lead to disrupted calls and internet connectivity issues, underscoring the importance of thorough testing before integration into Apple’s devices. The global giant’s CEO, Tim Cook, remains cautious about the potential impact of shipping a flawed modem.
Apple’s Pursuit of Modem Independence
The tech giant’s pursuit of an in-house modem chip reflects its broader strategy for hardware independence. However, the challenges in meeting performance standards and complexities comparable to Qualcomm‘s technology highlight the intricacies of modem development.
The potential delay underscores the meticulous approach Apple takes to ensure the reliability and functionality of its devices, especially with critical components like the modem. As the company navigates this journey, its long-term goal of reducing dependence on external suppliers remains a central theme in its broader hardware strategy.
