The new iPhone 16e is considered to beDespite its high price compared to the features it hasThe iPhone 5 is a decent device, and one of the most notable technologies it comes with is the 1G C16 modem, which Apple designed itself. Although Apple spent at least seven years developing this chip, it was mentioned very briefly during the iPhone XNUMXe announcement, which may seem strange given the huge challenges Apple faces in designing such a technology that has been monopolized by Qualcomm for decades.
C1 chip
The C1 or Cellular 1 chip, which is being used for the first time in the iPhone 16e and is expected to be added to future Apple devices, is described by Apple as “the most energy-efficient modem ever in an iPhone.” The secret behind this claim is that this modem works in complete integration with the hardware and software inside the device, allowing for improved communication between all components and achieving better performance and greater energy efficiency and saving significantly.
The C1 chip also improves device performance using artificial intelligence and machine learning. According to a report from Reuters, if the iPhone is connected to a slow, crowded network, the processor can direct the modem to process the most important data first. This means that things you need urgently, like loading a web page or starting a video call, will happen more quickly instead of waiting for less important data.
Apple's opinions on the C1 chip
Johnny Srouj, Apple’s senior vice president of Hardware Technologies, explained how Apple sees this new addition: “We’re building a platform for generations to come. The C1 chip is the beginning, and we’ll continue to improve this technology with each generation, making it the platform that sets our products apart.”
Sarouj stressed that Apple’s goal is not to match every feature found in other companies’ modems, but to design integrated products in which the modem is just one part of the solution. The goal is to provide the best communication experience, which can only be achieved when the hardware and software are designed together, like the difference between a suit from a thrift store and a suit tailored for you!
So far, this has been evident in power efficiency, and it's expected that with improved design and smaller component sizes, performance and speed will see significant improvements, as will the shift to Apple silicon technologies.
Energy Efficiency
Power efficiency is the C1 chip’s biggest advantage, allowing you to watch video for up to 26 hours on the iPhone 16e. Battery life complaints are likely to disappear with future devices, as Apple works on longer-lasting batteries with lower power consumption, possibly due to the integration of all components and software.
Currently, the iPhone 16e offers a similar viewing and live video experience to previous models, and it also features faster charging than the iPhone 14 Plus. Can we expect devices with batteries that last more than 30 hours with the “C1 Pro” chip, for example, in the future? This possibility is not far from reality.
The C1 chip is actually a system of chips, including the transmitter, receiver, and baseband chips that connect via PCIe, which helps improve power distribution in hot or cold weather conditions. So, when using the 5G modem for data downloads or heavy tasks, you may notice that the iPhone heats up less and consumes less power, which is a big benefit for those working remotely.
Engineering and Manufacturing
Apple didn’t jump into 5G without careful and extensive research; the modem has been tested with 180 carriers in 55 countries, ensuring it works in every market where Apple devices are sold. The C1 chip is a complex piece of engineering; the baseband modem is manufactured using advanced 4nm technology, while the transmitter is based on 7nm technology.
Since 2019, Apple has been working to reduce its reliance on Qualcomm, after buying Intel’s chip development division for $4 billion. Now, Apple joins an elite group of companies that provide this technology, along with Samsung, MediaTek, Huawei, and Qualcomm. These chips also support GPS and satellite communications, in addition to the usual 5G and XNUMXG frequency coverage.
mmWave and Wi-Fi 7 support
As of yet, there is no Wi-Fi 7 or mmWave support enabled in devices. mmWave is the fastest form of 5G, but it has limited range, making it uncommon, even in the United States where it is not yet widely available.
We know that Apple has been studying mmWave technology, but Qualcomm holds several patents related to it. So far, Apple has not announced whether it will support the technology in the future or not. But that may not be a big deal, as mmWave is mainly used in the US, and has not yet been made available in the UK.
On the other hand, Apple may decide in the future to support these technologies in new versions of its chips, or perhaps invest in developing 6G technologies. As for Wi-Fi 7, it is a new technology that has not yet become widespread among users and companies, as most of them still use Wi-Fi 6, which provides speeds of up to 9.6 gigabits per second, compared to Wi-Fi 7’s speed of 46 gigabits per second. However, it seems that Wi-Fi 7 support will be a priority for Apple in the next generations of C2 chips.
Relationship with Qualcomm
It's no secret that the relationship between Apple and Qualcomm has been strained; Apple believes that Qualcomm's patent licensing fees are high, and the two sides have been locked in legal disputes over the matter.
However, Apple has spent seven years and billions of dollars developing its own alternative, and Apple's 5G modem is currently expected to be in 80% of its products by 2026, with the rest set to be replaced the following year after the licensing agreement with Qualcomm expires.
With Qualcomm still holding a number of important 5G patents, Apple will still have to pay some licensing fees, as it does with Arm for Apple’s silicon technology. But the main benefit for Apple is the ability to design a modem that is fully compatible with its devices, rather than using off-the-shelf components that may not fit the system perfectly.
Important technical specifications
Apple has revealed the technical specifications used in the C1 chip in the iPhone 16e, model A3212. Regardless of their names and technical complexities, what matters to us is that these specifications mean that the iPhone 16e supports the latest communication and fast internet technologies, works on most networks in the world, provides accurate location, with improvements in battery life and wireless connectivity.
With this combination of innovative design and intelligent integration between hardware and software, Apple once again proves its ability to deliver advanced technologies that improve the user experience and set new standards in the world of smartphones.
What lies ahead?
There’s a lot to speculate about when the C chips will go into the future. Will Apple integrate the modem into the main processor to create a high-performance, integrated SoC? Will it add Wi-Fi and Bluetooth support to the chip? Even if it doesn’t happen anytime soon, Apple is expected to start using its own chips for these technologies sometime this year.
As some are speculating that Apple may launch a very thin iPhone this year, the new modem may be one of the reasons for changing the internal design, allowing for the launch of thinner, more performing and more energy-efficient phones.
While some are wondering if this modem will open the door to a slim foldable iPhone to compete with Samsung's Fold phones? We'll just have to wait.
