For the last several years, Apple has been working to create its own 5G modem, with the eventual goal of eliminating the need to use third-party modem technology. Apple's 5G modem is inching closer to completion, and we could see the first iPhone with an Apple modem in 2025. This guide covers everything we know about Apple's 5G modem development. First Products With Apple's 5G Modem Swapping out a modem chip might not sound like a big deal, but tweaking cellular technology can have a major impact. Apple has to make sure that its 5G modem is as good or better than 5G chips from its current modem supplier Qualcomm before transitioning to its own technology. For that reason, we're expecting the 2025 iPhone SE 4 to be the first Apple device with the Apple-designed 5G modem. It is a lower volume device than a flagship smartphone, and it will let Apple see modem performance at scale in consumer hands before bringing the Apple modem to the main iPhone line. According to current rumors, iPhone SE 4 will come out in early 2025, likely sometime before April. After Apple releases the iPhone SE 4 with Apple modem, we could see it in a second device as soon as September 2025. Apple analyst Ming-Chi Kuo has suggested that the ultra-thin iPhone 17 "Air" or "Slim" that's in development will also use the Apple modem. Apple will ship an estimated 35 to 40 million iPhone units with the Apple modem in 2025, and from there, if all goes well, more iPhones will adopt the technology in 2026 and 2027. No mmWave 5G? In September, DigiTimes suggested that Apple's first 5G modem chip would not support faster mmWave technology, and would instead be limited to sub-6GHz 5G. mmWave 5G is the fastest 5G, but it is short range and limited to big venues and major cities. In suburban and rural areas, sub-6GHz is used. Sub-6GHz isn't as fast as mmWave 5G, but it is much longer range, which makes it more viable for widespread use. DigiTimes believes that Apple will continue to rely on Qualcomm modems for iPhone models that support mmWave, which is essentially U.S. iPhones. mmWave is still limited in availability in many countries, so Apple only has mmWave-capable modems in iPhones sold in the United States. Bloomberg's Mark Gurman has also said that one of the modem chips that Apple is developing does not have mmWave 5G, so that lends some extra credibility to the DigiTimes report. Possible All-in-One Chip A recent report from 9to5Mac suggested that Apple's first modem chip would in fact be more than just a modem, combining 5G connectivity, Wi-Fi, Bluetooth, and GPS into a single chip. That does not align with what we've heard from Gurman, however. While Apple is said to be working on an all-in-one chip, it isn't something that is expected for some time. Gurman believes the first version of the Apple 5G modem will not measure up to Qualcomm technology, and that the first custom design won't bring noticeable benefits for users. Apple is hoping that the modem will eventually evolve into a more advanced component, cutting down on the need for multiple chips to save money and internal space. With the two separate reports, it is not clear if the Apple chip will be a standalone modem or a chip that incorporates multiple components, but given reports of development difficulties, Apple might not be at the all-in-one chip point. Qualcomm Dispute Right now, all iPhones use Qualcomm 5G modems, and Apple has to buy the modem chips and pay a patent licensing fee for using Qualcomm technology. Back in 2017, Apple sued Qualcomm over anticompetitive patent licensing practices and also claimed that Qualcomm had failed to pay more than $1 billion in royalty rebates. After filing the lawsuit, Apple attempted to cut ties with Qualcomm and opted to use only Intel modem chips in the 2018 iPhone XS/XR models and the 2019 iPhone 11 lineup. Apple had used Intel chips for some iPhones in the past, opting for a mix of Qualcomm and Intel modems in different regions, but Apple wanted to stop relying on Qualcomm entirely. Intel-only chips were fine for the 2018 and 2019 iPhones, but for the 2020 iPhone 12 lineup, Apple wanted to transition to 5G technology. Apple's plan was to use Intel 5G chips, but Intel struggled with development. Intel missed developmental deadlines, and it became clear that Intel 5G chips were not going to happen. Apple needed the 5G modems from Intel to be functional and ready to test by summer 2019, and completed chips needed to be shipped to Apple in early 2020, which wasn't going to happen. Apple spoke with Samsung and Mediatek about the possibility of 5G modems to avoid having to make amends with Qualcomm, but it turned out Qualcomm modems were the only option. In April 2019, Apple settled with Qualcomm and the two companies dropped all litigation. Apple paid Qualcomm $5 to $6 billion in late royalty fees, and agreed to continue to pay ongoing patent royalties for every iPhone manufactured, plus the company signed a six-year licensing deal with Qualcomm. The 2020 iPhones ended up using Qualcomm's 5G chips, and every iPhone after that has also used Qualcomm technology. Apple most recently extended its modem licensing deal with Qualcomm through March 2027, so we will likely see Qualcomm modems in some devices up until then as Apple transitions to its own technology. Intel Purchase Just after Apple settled with Qualcomm, Intel announced plans to exit the 5G modem business. Intel was not able to make a 5G modem to compete with Qualcomm, and that was the end of Intel's modem business. Intel met customer commitments for existing 4G modems, but then-Intel CEO Bob Swan said there was "no clear path to profitability and positive returns" in the smartphone modem business. Intel decided to sell off its modem business, and Apple ultimately opted to acquire it. In July 2019, Apple and Intel inked a deal that saw Apple purchasing the majority of Intel's smartphone modem business. Approximately 2,200 Intel employees joined Apple, and Apple also took over Intel's related intellectual property, equipment, and leases, in a transaction valued at $1 billion. With the Intel purchase, Apple became the owner of more than 17,000 wireless technology patents, and the Intel employees joined Apple's cellular technologies group. The purchase was aimed at helping Apple accelerate 5G modem development, but Apple has still faced delays and design issues. Development Issues There have been rumors about iPhones adopting an Apple-designed modem chip since 2023, which is when the technology was meant to be ready. Kuo said in mid-2022 that Apple's modem work had "failed," leading to stalled development and a launch delay. Gurman said in late 2023 that Apple was forced to postpone the debut of an Apple modem until 2025 or 2026 due to development setbacks, and he claimed that the technology could "lag behind the competition by years." Apple has reportedly experienced issues with the Intel code it has been working with. Engineers have had to do rewrites, and adding new functionality has caused existing features to break. Apple also has to avoid infringing on Qualcomm patents with the chip, adding another layer of complexity. A September 2023 report from The Wall Street Journal suggested that Apple has run into problems because it had unrealistic goals, a poor understanding of the challenges involved in modem development, and completely unusable prototypes. Chips tested in late 2022 were allegedly "three years behind Qualcomm's best modem chip," and in danger of making the iPhone's wireless speeds slower than competitors. Release Date It's looking like we'll see the first Apple modem in the iPhone SE 4, which is expected in early 2025. From there, Apple will likely expand the technology to other devices, using a mix of Qualcomm and custom-designed chips until its own work on 5G modems is advanced enough to phase out Qualcomm entirely.This article, "What You Should Know About Apple's 5G Modem" first appeared on MacRumors.comDiscuss this article in our forums
