IPhone C1 modem: What is it, what does Apple go from here?

Almost hidden in the announcement of the iPhone 16th, Apple dropped something from a bomb: it produces its own 5G modems now. This has of course been subjected to rumor for a long time and frankly took more time than expected; Apple bought the Division of Intel Modem in 2019 for its patents and engineers, in order to produce its own cellular modems instead of buying them from Qualcomm.

There was a time, in fact, where we were not even sure that it would never have been out, but now that Apple's first cellular modem is here, what do we know about it? What don't do it We know? How will it shape the future of the iPhone and other Apple products? Here is everything we have learned about Modem C1 so far.

What is C1?

C1 is Apple's first cellular modem. It follows the denomination scheme of other processors that Apple makes: the series A for “application processors”, the H series for “headphones”, the M series for “Mac processors”, the R series for “Reality Processors “, The U series for” Ultrawideband “, etc.

A cellular modem is the processor that takes signals from the antenna and transforms them into usable data, and vice versa. This is the main part responsible for your connection with cellular networks, and with other design considerations, plays a large role in the speed and reliability of the cellular connection of your iPhone as well as the life of the battery life .

With the C1, Apple uses a cellular modem for the first time of its own design. Apple buys Qualcomm cellular modems, mainly, from the original iPhone in 2007. The iPhone 11, the iPhone XS / XR and the 2nd generation iPhone, as well as some variants of the iPhone X , presented certain LTE 4G cellular modems produced. By Intel, but since the iPhone began to support 5G with the iPhone 12, all modems were manufactured by Qualcomm.

How does C1 compare to other 5G cell modems?

The C1 supports most of the spectrum and existing bands of the modems found in Apple's iPhone 16 line, including 4G LTE and 5G, with 4 × 4 Mimo. HSDPA and MMWAVE is missing with a dual portal holder. The most common 5G is called “sub6 GHz” and uses the same general frequency ranges as other cell connection standards.

There are a lot of modem to do to maintain a reliable connection and a good speed, and we just don't know how the C1 works in this regard. It can be as fast as Qualcomm modems in sub6 bands, or it can be slower. It can be disconnected more often, or it can be more reliable. Until we got good independent tests, we just don't know.

In an interview with Reuters after the launch of the iPhone 16th, Apple says that it has built the C1 to better manage the areas with a spotted service: “For example, if an iPhone meets crowded data networks, the processor Telephone can point out to the modem which traffic is most sensitive to time and has highlighted them other data transfers, making the phone more sensitive to the user's needs, said Arun Mathias, Vice-president of wireless software at Apple. “”

Apple says that the main basic strip is made with a 4-nanometers process and the transceiver with a 7 NM process. It is quite advanced for a cellular modem, but not unknown. Apple seems to suggest in its marketing that the C1 is particularly economical in power, but we cannot just assume that the lifespan of the long -claimed battery of the iPhone 16th is mainly due to an improvement in cellular efficiency – it There are many other factors at stake, such as battery capacity, A18 processor, display efficiency, etc.

The absence of millimeter waves is likely to attract the most attention here to the United States, where these frequencies are more common than in the rest of the world. It is the very fast but very short cells of cells that give you multi-Gigabit speeds but do not travel more than one block or two and do not penetrate the walls.

Once the iPhone 16th is published and that more independent tests can be carried out which specifically target MoDem C1, we will update this section with the results.

Will Apple use C1 in future products?

It is not clear if Apple will use C1 in a product other than the iPhone 16th. The iPhone 17 line should again include Qualcomm modems, because Apple has signed a six -year chipset contract with Qualcomm in 2019 with a two -year option to extend.

However, the cellular versions of the Apple Watch and the iPad also use cellular modems, and these products could very well include C1, especially if it is more economical in power, because the high -end cellular speed is less important than in the iPhone.

Will there be a C2, C3, etc.?

As Apple develops future cellular modems, we expect the company to use C chips in all its products connected to the cell. In an interview with Reuters, the senior vice-president of Apple Johny Srouji material technologies said: “C1 is the start, and we will continue to improve this technology at each generation so that it becomes a platform for us Who will be used to really differentiate this technology for our products.

Before publishing the C1, it was said that Apple had a three -step plan in preparation. The first chip would appear in lower priority products and, as such, would be lower than the high -end modem of Qualcomm. The C1 of the iPhone 16th seems to respond to this prediction.

The next chip (C2) would come about a year later and make up for the best of Qualcomm. It would be presented in more Apple products, which means that we will probably see its beginnings in the iPhone 18 line. After three years, Apple is supposed to be on its third generation chip, the C3, which should “beat” Qualcommm , how Apple will go to its own cellular modems for all products.

In addition to advancing capacities through generations, Apple intends to possibly integrate the modem into its main SOC conceptions (system on chip). This is common with some of the Qualcomm snapdragon processors used in Android phones, for example, and this helps improve energy efficiency and reduce the size and complexity of the internal components of the iPhone.

What about Wi-Fi, bluetooth, ultra-large band and other wireless chips?

Apple already manufactures its own ultra -wide (The U1 and U2) chips and uses them in iPhones, Airtags, Apple Watch and the AirPods Pro 2 load box.

The company is based on companies of companies like Broadcom for Bluetooth and Wi-Fi, but it will not last too long. Apple is developing its own Wi-Fi and Bluetooth chip and should start using it in products this year. (We will have to wait for the first wanderings, but it does not seem to be part of the iPhone 16th, which only supports Wi-Fi 6.) The new chip could make its debut in the iPhone 17, or in a Another product like the Homepod Mini or Apple TV, but it is unlikely that we hear a lot before the demons.

Apple's Wi-Fi flea should support the latest Wi-Fi 7 specifications and offer what reports say they are “improved connectivity”.
