Apple’s development of the C1 modem is not just about hardware—it’s a declaration of independence from a company that once held significant leverage over its products.
Apple’s reliance on Qualcomm modems dates back to the early iPhone generations when Qualcomm’s chips were the industry standard for reliable cellular connectivity. For years, Apple paid Qualcomm substantial licensing fees for its patented modem technology. However, as Apple’s ambitions grew, so did its frustrations with the terms of its agreements.
One of the major turning points in the relationship came in 2017, when Apple filed a lawsuit against Qualcomm, accusing it of charging exorbitant royalties and engaging in anti-competitive business practices. Apple argued that Qualcomm had a stranglehold on the modem market, forcing device manufacturers to pay high fees even if they were using non-Qualcomm components. Qualcomm, in turn, countersued, leading to a global legal war that resulted in iPhone sales bans in certain markets.
The courtroom battles intensified over the following years, with both companies trading lawsuits in multiple countries. At the heart of the dispute was the licensing model Qualcomm employed—charging based on the total cost of the device rather than just the modem itself. Apple, under CEO Tim Cook’s leadership, sought to break free from this model, believing that it was paying far more than necessary in licensing fees.
Despite the aggressive lawsuits, the two companies reached a temporary truce in 2019, signing a multi-year agreement that allowed Apple to continue using Qualcomm modems while working on its internal solution. But behind the scenes, Apple was making strategic moves to eliminate its dependence on Qualcomm once and for all.
One of the most significant steps in this strategy was Apple’s billion acquisition of Intel’s struggling modem division in 2019. This acquisition brought thousands of engineers and an extensive portfolio of modem-related patents under Apple’s control. By bringing modem development in-house, Apple gained full autonomy over a key component of its devices, eliminating the need for Qualcomm’s proprietary technology.
Apple’s unveiling of the C1 modem with the iPhone 16e is the long-awaited result of these years of preparation. While the C1 modem is still an early iteration and lacks certain features like mmWave 5G support, it marks the beginning of Apple’s phased transition away from Qualcomm. The company plans to gradually incorporate its modems into more devices, with a goal of completely phasing Qualcomm out of its supply chain by 2027.
For Apple, this shift is not just about cost savings—it’s about control. By designing its own modem technology, Apple can ensure tighter integration with its A-series chips, optimize power efficiency, and enhance security. This move also insulates Apple from supply chain risks and regulatory disputes, allowing it to dictate its own product development timeline without external dependencies.
Of course, Qualcomm is not taking this transition lightly. The company has already acknowledged that its modem business with Apple will shrink significantly in the coming years. To counterbalance this, Qualcomm has been expanding into new markets, including automotive chips and IoT devices, in an effort to diversify its revenue streams beyond smartphone modems.
Apple’s modem independence journey is far from over, but the introduction of the C1 represents a foundational step. As it refines its technology and moves closer to full autonomy in mobile connectivity, Apple is not just reshaping its own future—it’s altering the dynamics of the entire industry.

The long-anticipated move toward in-house modem technology is not just about Apple’s independence—it’s about reshaping the competitive landscape of mobile connectivity.
For Qualcomm, Apple’s shift represents a major threat to its long-standing dominance. Qualcomm has been the go-to provider of modem chips for nearly every premium smartphone, including iPhones, and the licensing fees it collects on these chips have been a significant revenue stream. Apple phasing out Qualcomm modems means Qualcomm will lose billions of dollars in annual revenue, forcing the company to rethink its market strategy.
Industry analysts have pointed out that while Qualcomm’s short-term financials may take a hit, the company has been preparing for this moment. Qualcomm executives have publicly acknowledged that they expect Apple to completely stop using their modems by 2027, and in response, Qualcomm has been aggressively expanding into other markets. The company has invested heavily in sectors like automotive technology, wireless networking, and AI-powered computing. Additionally, Qualcomm is still dominating in the Android smartphone space, where manufacturers like Samsung, Google, and Xiaomi continue to rely on its technology.
But Apple’s decision to bring modem development in-house is about more than just reducing dependency—it’s about redefining standards. The industry has long operated under Qualcomm’s patents and proprietary designs, meaning manufacturers had little choice but to pay licensing fees to ensure compliance with wireless network standards. However, Apple’s approach could inspire other smartphone makers to pursue in-house modem development as well, potentially loosening Qualcomm’s grip over the mobile chipset market.
Samsung, for instance, has developed its own Exynos modems, although it still leans on Qualcomm for its flagship devices in key markets. Companies like MediaTek, which primarily serves mid-range and budget smartphones, are also expanding their modem technology to compete at higher levels. Apple’s shift away from Qualcomm could accelerate this trend, pushing manufacturers to invest in their own wireless solutions rather than relying on Qualcomm’s chips.
Meanwhile, major telecom carriers are also keeping a close eye on Apple’s modem transition. Performance and network reliability are paramount for mobile providers, and Apple’s in-house modem will need to prove itself in real-world conditions. Early industry reports suggest that while the C1 modem delivers solid performance, it lacks mmWave 5G support, meaning devices equipped with the C1 may not reach the highest speeds available on certain networks. Carriers that have invested heavily in mmWave infrastructure may need to adjust their approach when marketing Apple’s future devices.
Another key consideration is regulatory scrutiny. Qualcomm has long been the subject of antitrust investigations globally, particularly concerning its licensing practices. Apple’s exit from Qualcomm’s modem ecosystem could give regulators more reason to scrutinize Qualcomm’s business model, especially if other smartphone makers begin to follow suit. At the same time, Apple itself could face regulatory attention, given its growing dominance in mobile chip development.
Consumers, on the other hand, are likely to benefit from this competition. As Apple refines its modem designs and integrates them more tightly within its ecosystem, users can expect better battery efficiency, more stable connections, and a modem tailored specifically to iOS performance. Moreover, increased competition in the modem sector could drive innovation and lower costs across the board, benefiting not just Apple customers but the entire smartphone industry.
Apple’s transition to in-house modems isn’t happening overnight, but the impact is already visible. With the iPhone 16e debuting the C1 modem, Apple has officially taken the first step toward full autonomy in mobile connectivity. As the company iterates on this initial design, the industry will be watching closely to see if Apple’s gamble pays off—not just in technological improvements but in shaking up the competitive landscape that Qualcomm has largely controlled for years.
Apple’s roadmap for its modem technology extends far beyond the C1 modem, marking the beginning of a long-term strategy to eliminate third-party dependencies and establish itself as a leader in cellular connectivity. While the launch of the C1 modem in the iPhone 16e is a pivotal milestone, it is only the foundation for Apple’s greater ambitions.
Industry insiders suggest that Apple is working on an advanced second-generation modem, internally referred to as the “Ganymede” project. This iteration is expected to bring significant upgrades over the C1 modem, most notably support for mmWave 5G technology. Apple’s current modem lacks this capability, which means that high-speed 5G performance in some regions is still reliant on Qualcomm’s modems. With Ganymede, Apple aims to close this gap, potentially bringing higher-speed connectivity to future iPhone models starting in 2026.
Beyond Ganymede, Apple’s ultimate goal is to introduce its next-generation modem, codenamed “Prometheus,” by 2027. If Apple succeeds, Prometheus could surpass Qualcomm’s best offerings in performance, efficiency, and security. The modem is expected to feature custom RF (radio frequency) components, deeper integration with Apple’s A-series chips, and proprietary AI-driven optimizations for network performance. Apple’s advantage here lies in its ability to tightly integrate hardware and software in ways no third-party modem vendor can.
Apple’s innovations don’t stop at smartphones. The company is reportedly designing a custom modem for future iPads, MacBooks, and even wearables such as the Apple Watch Ultra. By expanding its modem capabilities beyond the iPhone, Apple can further optimize network performance across all its devices and unify connectivity under a proprietary system. The potential for a fully Apple-controlled wireless ecosystem could lead to seamless device switching, improved battery life, and exclusive network features available only to Apple users.
While Apple’s modem roadmap is ambitious, it does not come without challenges. Developing modem technology is incredibly complex, requiring compliance with international telecommunications regulations, carrier certifications, and years of rigorous testing. Apple’s phased approach—starting with the C1 modem in the budget-friendly iPhone 16e and gradually rolling it out to premium devices—suggests it is taking a cautious but calculated path toward full independence.
In parallel, Apple is rumored to be investing heavily in satellite communication technologies. The iPhone 14 introduced emergency SOS via satellite, but future Apple modems could take this concept further, improving satellite-based communication for regions with poor cellular coverage. This could be particularly beneficial for travelers, remote workers, and industries that rely on connectivity in harsh environments.
Apple’s modem plans also have broader implications for the industry. As Apple moves toward vertical integration, it may pressure competitors like Samsung and Google to accelerate their in-house modem development. Additionally, Qualcomm will need to shift its focus beyond traditional smartphone contracts, doubling down on emerging markets like automotive, IoT, and AI-driven networking.
Apple’s approach to modem independence is not just about cutting ties with Qualcomm—it represents a broader strategy to redefine mobile connectivity under its own terms. By 2027, Apple’s vision is expected to materialize fully, marking a revolutionary shift in how its devices connect with the world.
