Apple’s ambition to control every aspect of its hardware is evolving once again. After successfully transitioning from Intel processors to its proprietary Apple Silicon in Macs, the company is now setting its sights on an even more intricate challenge: replacing Qualcomm’s cellular modems and Broadcom’s networking chips across its product lineup. This shift has already begun with the C1 modem, debuted in the iPhone 16e, marking the first step in a multi-year plan to bring all networking technologies under Apple’s control.
Apple has always preferred to own the technology that powers its devices, aiming for greater efficiency, tighter hardware-software integration, and cost savings. With modem and networking chips among the last third-party components in its stack, Apple’s roadmap points to a future where every core technology is developed in-house.
The transition won’t be instantaneous — or simple — but Apple’s roadmap reveals an aggressive plan that will culminate in completely in-house modem and connectivity solutions by 2027, with even deeper hardware integration planned for 2028 and beyond. Here’s what’s happening, and why it matters.
Apple’s In-House Modem Roadmap: Developments
2020: Apple successfully transitions Macs to Apple Silicon from Intel, finishing the shift in under three years.
2024: Apple launches the first in-house 5G modem, C1, in the iPhone 16e. It prioritizes efficiency over performance and lacks full 5G mmWave and wavelength support.
C1 Usage: Limited to low-power devices like iPhone 17 Air, highlighting its power-saving advantages in thin and compact devices.
Performance: Apple claims it’s “the most power-efficient modem ever on an iPhone,” yet still behind top-tier Qualcomm alternatives.
Next Steps: Apple is developing C2 (Ganymede) and C3 (Prometheus) to bridge the performance gap.
C2 (2026): Debuts in iPhone 18 and iPads (2027). Adds support for mmWave, 6 Gbps speeds, and advanced carrier aggregation — matching Qualcomm.
C3 (2027): Launches with iPhone 19. Targets to outperform Qualcomm, including AI enhancements and next-gen satellite connectivity.
Cellular MacBooks: Expected by 2026, thanks to in-house modem capabilities.
Wi-Fi & Bluetooth: Apple is also replacing Broadcom’s chips with an in-house networking chip, Proxima.
Proxima (2025): Launches in updated HomePod mini and Apple TV. Adds Wi-Fi 6E and potential router-like functionality.
iPhone 17: Proxima expected in all models, according to analyst Ming-Chi Kuo.
Unified Chip Design: Apple aims to merge the modem with its primary SoC, such as the A-series, by 2028, simplifying hardware and improving efficiency.
What Undercode Say: Deconstructing Apple’s Silicon Domination Strategy
Apple’s goal to eliminate dependency on Qualcomm and Broadcom reveals the brand’s relentless pursuit of vertical integration. Let’s analyze the strategic implications and challenges behind Apple’s plan.
1. Efficiency vs. Performance
The launch of the C1 modem is a soft entry — efficient, but not a flagship performer. Apple isn’t rushing into the high-stakes modem arena blindly; it’s deploying C1 where efficiency matters most, such as in lightweight phones like the iPhone 17 Air. This avoids direct comparison with Qualcomm’s elite modems while laying the groundwork for future iterations.
2. C2 and C3 as Qualcomm Killers
Ganymede and Prometheus are not just about catching up — they’re Apple’s shot at leadership. C2 is expected to meet Qualcomm on equal terms. But Prometheus, with AI features and satellite capabilities, indicates Apple wants to leapfrog Qualcomm’s roadmap entirely. It mirrors Apple’s A-series chip domination, aiming not just for parity but for market leadership.
3. Cellular MacBooks: A Quiet Game-Changer
Built-in cellular support in MacBooks will redefine productivity on-the-go. With its own modems, Apple can fine-tune this experience without compromises, and even reserve exclusive features for macOS.
4. Broadcom Replacement: Under-the-Radar but Big
The Proxima chip hasn’t garnered the same attention as the modem transition, but it could be just as impactful. By introducing router-like capabilities and better cross-device integration via in-house networking silicon, Apple could reimagine how its ecosystem communicates — tightly, efficiently, and privately.
5. Cost and IP Control
Beyond performance and efficiency, cost is a huge driver. Apple has long paid licensing fees to Qualcomm and Broadcom. Eliminating these third-party dependencies saves money, allows Apple to avoid regulatory issues, and gives full control over IP — a critical advantage in today’s geopolitically tense tech landscape.
6. Risks Involved
Apple is entering a space dominated by firms with decades of radio and network engineering experience. If its in-house modems underperform or cause signal issues, consumer trust could erode. Furthermore, integrating modems into SoCs by 2028 introduces a level of complexity that could slow down innovation if problems arise.
7. Ecosystem Advantage
When Apple owns the modem, the Wi-Fi chip, and the SoC, it can optimize features like continuity, AirDrop, FaceTime over 5G, iCloud syncing, and more — making them smoother and more reliable across devices. It’s a silent competitive edge that no Android manufacturer can easily replicate.
8. AI and Satellite Integration
Prometheus’ focus on AI-driven performance and satellite support underlines Apple’s broader vision: future-proofing. While today’s focus is speed, tomorrow’s edge will be intelligent connectivity — knowing when and how to prioritize bandwidth, battery, or fallback to satellite.
Fact Checker Results
Apple’s C1 modem does not support mmWave — confirmed via multiple teardown reports and official spec sheets.
Mark Gurman’s forecast aligns with internal Apple timelines — consistent with historical reporting accuracy.
Ming-Chi Kuo’s claim of Proxima integration in all iPhone 17 models is speculative but backed by solid supply chain data — plausible but unconfirmed.
Prediction
By 2027, Apple will no longer rely on Qualcomm or Broadcom for any major networking component. Instead, the company will have a unified architecture — where modems, Wi-Fi, Bluetooth, and even future AI radio enhancements are custom-tailored for Apple hardware. Expect tighter ecosystem features, longer battery life, and exclusive performance upgrades that solidify Apple’s dominance not just in devices, but in connectivity technology itself.
