Rumor mill: A number of weeks in the past, Ming-Chi Kuo, a well known sell-side analyst, tweeted that his checks point out Apple’s effort to construct their very own mobile modem might have failed. In this column we need to stroll by this — the probability of it, the potential causes, and among the implications.
Kuo is mostly well-regarded. Based in Asia, he appears to have some excellent perception into the availability chain. Like all analysts, his monitor document is way from 100% on predictive potential, however typically talking he appears to get extra proper than incorrect with issues that pertain to the availability chain (much less so with Apple’s software program).
Guest writer Jonathan Goldberg is the founding father of D2D Advisory, a multi-functional consulting agency. Jonathan has developed development methods and alliances for corporations within the cellular, networking, gaming, and software program industries.
So is he proper this time? We suppose it’s too quickly to inform. The cellphone in query is the 2023 iPhone, which continues to be 14 months away. Typically, provide choices for the iPhone get locked down round 12 months upfront, so possibly there may be a while for change.
On the opposite hand, the modem is a crucial a part of the cellphone, extra on that in a second, so the remainder of the iPhone staff can in all probability solely make a bunch of different choices after the modem is mounted. So we’re within the ballpark. In some future publish, we’ll deconstruct sell-side information sourcing a bit, however for our functions right here, we might give at the least even odds that Kuo is right.
[Company Update] Qualcomm (QCOM.O)
My newest survey signifies that Apple’s personal iPhone 5G modem chip improvement might have failed, so Qualcomm will stay unique provider for 5G chips of 2H23 new iPhones, with a 100% provide share (vs. firm’s earlier estimate of 20%).

Apple’s chip staff, Apple Silicon, is an extremely proficient group. We often describe them because the best-run semiconductor firm on the planet. They have scored all types of spectacular achievements just like the M Series CPU and the industry-beating A Series software processor for telephones. How may they fail at a modem? Put merely, modems are onerous.
Modems, additionally known as basebands, are the chip that join a tool to the mobile community. Without a modem an iPhone is simply an iPod (which don’t exist anymore). As we famous above, modems are often the primary design resolution made when constructing a cellphone, every little thing else is dependent upon that selection, they’re the final word strategic high-ground in telephones. But what do they do?
— Enter over-simplification mode —
Phones obtain radio waves, the RF Chain interprets these radio waves into 1’s and 0’s and ship these to the modem. The modem then takes these indicators and decodes them into significant enter – a talking voice, a streaming video, and so forth.
Crucially, the principles that govern that decoding are decided by the wi-fi requirements – aka 4G, 5G. But what are these? They are some phenomenally difficult math that cowl the vagaries of the realities of radio waves touring lengthy distances. They incorporate all types of eventualities round sign loss, interference and a few very advanced encoding schemes. In some methods, they’re dealing with directions for a protracted record of nook instances. Crucially, what they don’t seem to be is a predictable stream of knowledge or deterministic code ready to be executed.
— Exit over-simplification mode. Bonus factors: solely 3 acronyms. —
To put it mildly, modems are very completely different from CPUs or GPUs, not to mention task-specific AI ASICs. As such, creating them requires a really completely different ability set from designing these different chips. If you have a look at an uncapped CPU, there are clear patterns, like taking a look at industrial farm plots from 30,000 toes. Uncap a modem and it appears to be like a lot much less tidy, extra akin to the plots of a village of Middle Age serf-bound farmers. (And for what it is value, it is extremely onerous to discover a photograph of those on-line, partly as a result of they’re so unappealing to have a look at.)
So it is extremely potential that Apple simply didn’t have ample design expertise to construct the chip. If we needed to guess, possibly they accomplished a design however discovered that its energy efficiency didn’t meet expectations. It is necessary to keep in mind that Apple has failed at constructing networking chips earlier than. Ten years in the past they acquired a Wi-Fi/Bluetooth staff from Texas Instruments, however immediately Apple continues to be shopping for these chips from Broadcom.
Which leads us to Intel.Three years in the past, Apple acquired the cellular staff from Intel, round 1,000 folks. Intel had acquired the staff from Infineon, and for a quick second provided modems to Apple. Then 5G occurred, Intel was not prepared, and so Apple needed to settle its $1 billion lawsuit with Qualcomm and purchase components from them. Apple valued the acquisition at $1 billion, and we all know folks at Intel who’re giddy about that quantity. Intel introduced with it a workable 3G/4G modem, and the considering was Apple Silicon would then exit and design the 5G portion. Now actuality appears to have set in.
What occurs subsequent? If this rumor seems to be correct (on no account sure) that is clearly excellent news for Qualcomm. Last 12 months, they warned that they count on their share of Apple modems would shrink to twenty% from 100% within the 2023 mannequin. At the time, this was held up as proof that Apple’s plans have been set in stone. However, our conversations then indicated that this was only a good transfer by Qualcomm’s Investor Relations staff, it meant they might not need to spend 25% of their query time for the following years answering the identical questions over and over.
That being stated, it is extremely potential that Apple’s modem may be late. When we wrote about it final we instructed that the 2023 deadline wouldn’t be achievable however 2024 or 2025 may. There isn’t any purpose (but) to suppose that Apple has solely deserted the challenge.
There are nonetheless 114 jobs on the Apple jobs website that point out modems. This is down loads from final 12 months, however doesn’t sound like an organization radically altering course. Again, Apple Silicon could be very effectively run, and we strongly suspect that they’ve numerous hopes pinned on their very own modem. True, they are able to persuade Qualcomm to produce these options, however Apple doesn’t have numerous leverage for the time being.
Ultimately, we’re not solely stunned by this information. Building a modem could be very troublesome, as evidenced by the very lengthy record of corporations who’ve tried and didn’t construct one. In the broader sense, there’s a rising notion that Apple Silicon might have misplaced its magic. Dylan Martin of The Register, for one, has carried out some nice protection on excessive stage departures from the staff. We are inclined to suppose that Apple Silicon is doing simply high quality, however the modem exhibits that they’re, in any case, nonetheless mortal.
