Apple's Internal Hardware Team Is Working On Modems That Will Likely Replace Intel (arstechnica.com) 81

An anonymous reader quotes a report from Ars Technica: Apple will design its own modems in-house, according to sources that spoke with Reuters. In doing so, the company may hope to leave behind Intel modems in its mobile devices, which Apple has used since a recent falling out with Qualcomm. According to the sources, the team working on modem design now reports to Johny Srouji, Apple's senior vice president of hardware technologies. Srouji joined Apple back in 2004 and led development of Apple's first in-house system-on-a-chip, the A4. He has overseen Apple silicon ever since, including the recent A12 and A12X in the new iPhone and iPad Pro models.

Before this move, Apple's modem work ultimately fell under Dan Riccio, who ran engineering for iPhones, iPads, and Macs. As Reuters noted, that division was heavily focused on managing the supply chain and working with externally made components. The fact that the team is moving into the group focused on developing in-house components is a strong signal that Apple will not be looking outside its own walls for modems in the future. In recent years, Apple has been locked in a costly and complex series of legal battles with Qualcomm, the industry's foremost maker of mobile wireless chips. While Apple previously used Qualcomm's chips in its phones, the legal struggles led the tech giant to turn instead to Intel in recent iPhones.

    I'll be interested in seeing how this turns out. Apple has had great success with their ARM SoC design, and I don't doubt they can design a modem and baseband, but will they be able to design something that provides similar performance to what Qualcomm produces. Intel hasn't had a lot of success outside of x86, so I don't know how much of their failings can be pinned on the company, but rolling your own hardware is no small task.

    If nothing else, I suspect that there are some Qualcomm on Intel employees who work on these designs that are about to receive some job offers with very attractive salaries.

      I think the even bigger question is: can they do it while avoiding the patent minefield that Qualcomm and, presumably, Intel (and the other big players, like Samsung) have laid surrounding cellular modems.

      • The whole point of the RAND patent pool around standards for things like wireless modems, is exactly so there will not be a minefield - just a tollbooth of relatively known quantity.

      Wireless communication is a pretty tech and research intensive field. Then again, so is microprocessor design.

      There is immense demand for the technology and Qualcomm won't be on the top of the pile for long with the way they keep behaving.

      Intel made a good stab at it, but Intel has severe structural problems as a company that dooms their side ventures to failure.

      Apple has been good at developing first party parts for their products and if anyone has a chance they will- They'll also have the good sense to ab

      Apple has had great success with their ARM SoC design,

      I suspect a large part of this success is not due to technical superiority, but getting priority at newer (lower power) fabs due to Apple's large volume of orders. Their Ax processors were the first to use the smaller lithography available from fabs, which meant a corresponding reduction in power consumption for the same level of performance (or alternatively, better performance at the same power consumption). Back when they still used Samsung as a fab, even Samsung Semiconductor prioritized Apple's order ahead of Samsung Mobile's own Exynos SoCs.

      If you remember the whole mess over the Nvidia Maxwell GPUs (the 8xx and 9xx series) not performing as expected, it's for the same reason. Nvidia assumed they'd be able to use TSMC's new 16nm and Samsung's new 14nm processes to manufacture Maxwell, and designed Maxwell assuming the thermal limits of those lithographies. But Apple's order for Ax processors bumped them down in the queue. That forced Nvidia to manufacture Maxwell on 28nm, leading it to overheat until they redesigned it with fewer cores, meaning it under-performed. It was so bad they actually re-used the Kepler architecture (700x series) for their higher-end mobile 8xx GPUs, since it was already optimized for the thermals of 28nm. Pascal (10xx series) was manufactured on 14nm and 16nm as expected, and was a success.

      • NVIDIA never manufactured anything at a Samsung fab and the processes are not even compatible.

        You would have to redesign the chip to manufacture it there.

    • "Intel hasn't had a lot of success outside of x86"

      Intel's greatest success outside of x86 has been... their cellular modems. Until the XMM 7560 their modems used ARM cores for the communications processor and were manufactured on TSMC processes.

    • Apple supposedly opened an office in San Diego right next to where Qualcomm designs its baseband processors.
      You can guess why.

  • I'm surprised they taken until now to begin this. Having your own silicon design team, who have already produced the W2 chip for the ear buds (yeah I know different ball park but still a toe dipped in wireless), you'd think you'd have started this back when they picked a fight with Qualcomm.
    Also with the perpetual drive to put everything on a single chip and use less space this seems like an obvious move.
    I'm guessing it's their habit of focusing on just a few things (CPU, Graphics & AI silicon) that has

    After they moved chip production in-house with their A-series, which has routinely been benchmarking far ahead of contemporary chips from Qualcomm, people started wondering when they'd do the same with cellular modems. Their recent spat with Qualcomm and their reliance on a lesser product from Intel may have hastened their decision to take it on themselves.

    It'll be interesting to see if, when, and how it pans out. With their processors and GPUs, they were able to build on top of ARM and Imagination tech, respectively (though they're now doing their own thing with the latter), but what do they build on with modems? And how will they avoid Qualcomm's prodigious patent portfolio covering the technology?

      Well one thing they might want to do is make cellular connectivity common, even is it's not the latest and greatest standard. Right now you get WiFi+BT on almost everything but cellular is always a big extra. Yes, you can use the phone as a hotspot but a laptop has a bigger battery, better space for an antenna and you're more likely to have that plugged in. If it's an in house design they can throw in there for the cost of die space it could be a mass market feature instead of a road warrior niche.

      • cellular connectivity is only good when it's not locked in any way and has a dual sim as well.
        But DO NOT REPLACE e-net or wifi with cell only. We do not need to pay $10-40/mo outlet fee per device or be stuck with 15-20G caps.

      Production, really ? I think that they only design them.

  • It's just intolerable on LTE and 5G. This was a test I ran today of bloat on tethered android cell phone - 2+ seconds of observed delay: http://www.dslreports.com/spee... [dslreports.com] Early tests of 5G are equally dismal, with over 1.5 seconds of observed latency under load. As osx adopted fq_codel (RFC8290) last year for their wifi drivers, awareness of this problem has finally made it to at least some of Apple's upper management. Here's hoping it's made it to the lte folk there also!

        • In wifi, now, at least, uplinks are easily controlled at the user device (phone), which is what I was mostly measuring.

          And how does that fix the monumental amount of equipment that results in buffer bloat between your phone and the target you're accessing?

          The user is not in control in this in the slightest. All they can do is not make it worse than the many hops already in the system. Apple won't fix your buffer bloat. They can't. All you can ask them to do is not make it worse.

          • by mtaht ( 603670 )
            bufferbloat only occurs at the slowest bottleneck link. This is usually the phone on the uplink and the e-node-b or vpn backhaul on the downlink. It can certainly happen elsewhere in the network but that's the vast majority of cases.
            • No it doesn't, it occurs on any bottlenecked link including the backhaul. It doesn't need to be the slowest link in the chain.

  • To avoid licensing they will create a new standard which is bad for everyone.

    This is not the same as Apple and its A-series SoCs. Apple purchased licenses from ARM Holdings to produce their own ARM-based CPUs. There is no one single company Apple can go to to license the technology to produce its own baseband chipsets. Additionally, Apple is in a very public battle with Qualcomm about the very patents and licenses that underpin 3G/4G/5G baseband technology.

    The patent licensing aside, one of the other Qualcomm lawsuits involves the violation of NDAs and Apple violating Qualcomm's baseband technology trade secrets. In order to integrate Qualcomm's chipsets into the iPhone, Apple entered into NDAs with Qualcomm for detailed technical information. Qualcomm alleges that Apple shared these secrets with Intel after Apple dumped Qualcomm chipsets. Even if Qualcomm cannot prove that Apple did this, it is going to be impossible for Apple to prove that they somehow did not use this same information to produce their own baseband chipsets. I believe this is a much bigger issue for Apple than the patent licensing issue. Undoubtedly there will be direct non-compete clauses in these NDAs.

    Short of actually purchasing Qualcomm, or some other baseband chipset manufacturer, it will be impossible for Apple to show that they have come up with their own cleanroom implementation of baseband chipsets that is unencumbered by some kind of patent or licensing issue or NDA contractual issue.

  • This particular chip or sub chip is not really high end anymore, it’s easy to make a modem in house thats still faster then the network it’s connected to.

    A simple cost saving equation, keep the simple stuff in house.
    • Undoubtedly, Apple would have their own chips already running in a lab somewhere. They can make all the chips they want in-house, as long as they are for internal use only in their labs, but the moment they incorporate those chips into a commercial device then they immediately become subject to patents and licensing issues. Even if Apple could somehow claim they have come up with a completely clean room implementation (which is rather impossible given their past technical collaboration with Qualcomm, and no

  • It will come at huge cost, increasing price of phones (gotta absorb R&D and production cost). Only companies specializing in modems make money from their production.
    And good luck with entering that market and not infringing on some patents.
    They'd be better off with making a joint venture with Intel.
