Intel Breaks Qualcomm's Hold On Apple's Baseband Chips (wsj.com) 84

Long-time Slashdot reader randomErr writes: In a big blow to Qualcomm, Apple plans to incorporate Intel baseband chips into at least some models of the new iPhone 7. The selection of Intel chip means that in newer iPhones Apple will no longer support CDMA technology popularized by Qualcomm. The Wall Street Journal states that many industry analysts believe Intel could be supplying as many as half of of baseband chips for Apple's handsets.
This was the last key iPhone component that didn't have two sources, and the Journal estimates that Intel's revenues could now increase by up to $700 million before the end of 2016.

    They have to - Verizon and Spring still need to finish deploying more GSM/LTE spectrum before they can finally abandon CDMA. Until then Apple still has to buy chips from Qualcomm for phones sold into Verizon/Sprint customers. The difference for the 7/7+ is that Apple has a GSM/LTE-only SKU that uses the Intel chips, for AT&T and T-Mobile (and global) customers.
    • It's a common misconception that CDMA is only used on Verizon and Sprint; practically all GSM carriers use a combination of three modulation schemes (and three radios), those being TDMA (aka 2g), CDMA (aka 3g), and OFDMA (aka 4g). GSM carriers have been using TDMA and CDMA for decades, though they used TDMA for voice and CDMA for data (TDMA efficiency is bad akin to old token-ring networks) hence a few years back, having two radios meant only GSM phones could do both voice and data simultaneously. The main

        UMTS (the 3G GSM standard) uses a CDMA-based modulation scheme, yes, but that is totally unrelated to what is discussed in this article. What the new Intel chips do not support is the IS-95 standard and derivatives, which also uses a CDMA-based scheme, but is otherwise unrelated, and which is misleadingly referred to just as "CDMA". UMTS is supported just fine by either modem.

        Verizon, Sprint, etc. use IS-95 and successors (CDMA2000, EV-DO, etc.) for 2G and 3G service. The GP is correct that Verizon and Sprint would need a complete LTE rollout to turn that off and use only the standards that form part of the GSM family tree (GSM, UMTS, LTE).

        • What the new Intel chips do not support ...

          Intel makes BBs? I didn't even know, until now, that they did that, The vendors that spring immediately to mind when someone mentions BBs are Qualcomm, MediaTek, Broadcom, and... umm... Intel makes basebands? Did they buy someone?

        • Thanks for describing this in good detail, although I'm bound to forget the IS-95 stuff.

          So once Verizon and Sprint switch over to a complete LTE rollout, does that imply that any LTE phone will work w/ them - just slip a SIM in? Like right now, I have a Lumia 550 which I use internationally, but not in the US, since it's not supported by Verizon. But if Verizon and Sprint did go full LTE, would all LTE phones automatically be supported by Verizon and Sprint just as easily as they are by AT&T and T-

      Both GSM and CDMA are on the way out. The way phone makers and carriers are going is called Voice over LTE. Which basically means that in the future voice will be encoded and carried over the data LTE lines instead of a separate voice only system.

      The theory is this will make phones simpler, free up radio spectrum for other uses, and improve call quality. And it will. I have tested some voice over LTE hand sets and the call quality is much better than over GSM and CDMA.

      • by Anonymous Coward

        the THEORY may be that... the reality is that the carriers will charge more, the carriers will no longer sell or provide service for "feature phones" (aka dumb flip phones) requiring more expensive "smart phones" with their stupid smart phone surcharges and mandatory data plans.

        • There are feature phones that use the LTE network. Feature phones willl remain apart of the market for the foreseeable future as long as there is a demand for them.

          Not everyone wants, or needs a smart phone.

      • Both GSM and CDMA are on the way out.

        CDMA is much faster on the way out than GSM. Carriers need a fallback strategy and that will be GSM for the foreseeable future.

      • Both GSM and CDMA are on the way out.

        But it'll be at least a decade before the areas which are now (still) only 2G get VoLTE transmitters, much less the 3G sites.

        Watch the indicator on your phone as you drive through the countryside. 3G has been out how long and they still have 2G-only areas?

    • I don't think this made the Slashdot front page but Intel bought VIA's CDMA modem design and license [fiercewireless.com] about a year ago. Intel's modems currently only support GSM & LTE, whereas VIA never updated their CDMA modems to be LTE capable. It likely will take a couple years for Intel to integrate VIA's CDMA implementation with their LTE design, but once its done, Intel's modems will be just as capable as Qualcomm's.

      CMDA isn't only important for the US Verizon/Sprint market, the much more important reason to impl

      • I read that article as well. But by that time both Verizon and Sprint will have likely fully transitioned away from CDMA.
  • Personally, I always thought that the US should use the standard international bands. It makes buying foreign phones a huge pain.

      You can't have the government dictate stuff like that. Look at how few phones Europe has. The mandated GSM standard killed innovation and phones barely took off.

      In 'Murica it makes sense to not only have competing standards but to have them on different frequencies. (Can't have T-mobile talking to a AT&T tower). This sort of competition has let companies pick the best and most profitable route for roll out. As a result we have the cheapest, fastest most ubiquitous cell phone setup anywhere in the world.

      Capitalism wins again over dirty socialism and government intervention.

      • Alright, I see your point then. I just find it annoying. I think we only have second best but we have a massive land area. If there's anything we need to do it's to just ban data caps everywhere. Data costs virtually nothing to any ISP, it's coverage that costs money.
        • Well the problem with data caps is that while a cell tower services one phone in a certain area, it can't service any other phones. Yes, you can make the degree smaller with special antennas, but the problem stays the same: cell towers are a shared medium. If you allowed everyone to surf at full speed during the whole month, the network would collapse.

      • The principle of selling licenses of part of the spectrum is already a very big form of government intervention. Rather just allow any device to send at any frequency, and the people with the most powerful antennas will be able to get their signal over.

      • Sure capitalism will win when you live in a fantasy world or simply make stuff up (as you have done). Europe does not have "few" phones (http://www.pewglobal.org/2016/02/22/smartphone-ownership-and-internet-usage-continues-to-climb-in-emerging-economies/), but approximately as many as the corrupt US. Perhaps you're too young or too dumb to recall capitalism greatest triumph in 2008: the sub-prime mortgage that was started by American capitalists and provided a near disaster for all those "dirty socialism" c

      And by "standard international bands" you mean... what? Common European bands? Japanese? Chinese?

    GSM was based on TDMA - everyone gets an equal timeslice of the bandwidth, even if they don't actually use it. In CDMA, everyone gets an orthogonal code and broadcasts whenever they want to. Broadcasts by other phones raise the noise floor for your phone. SNR then scales depending on how many people are transmitting at any given time, and all the bandwidth gets distributed automatically and equally between only those transmitting at that time.

    TDMA was fine for voice. But when it came to high-speed data, GMS simply couldn't compete with CDMA's superior bandwidth allocation. They threw in the towel after a year - most implementations of 3G on GSM used wideband CDMA. They just named it UMTS, HSPA+, etc. because of sour grapes. This is why you could talk and use data at the same time on GSM phones - they had a TDMA radio for voice (still do), and a CDMA radio for data. CDMA phones used the same radio for voice and data (which were built on different protocols since voice was about a decade older) so couldn't do both simultaneously.

    Most LTE implementations are OFDMA - does the same thing as CDMA, except using orthogonal frequencies instead of orthogonal codes. OFDMA requires more processing power to separate out the individual broadcasts, which is why it came after CDMA. Early OFDMA implementations like WiMax sucked up too much power with processors of the time, and would drain a cell phone battery in about 2-3 hours. It wasn't until a few years ago that low-power processors allowed us to implement OFDMA while not requiring a recharge halfway through the day. But CDMA was pretty much the proof of concept needed to make OFDMA a reality. Before CDMA, nobody knew if a real-life cellular network with hundreds of devices broadcasting simultaneously using orthogonal signaling would actually work or scale like theory said it would.

    If the people saying the U.S. should've adoopted GSM had gotten their wish, our cellular data speeds today would probably be down below 1 Mbps. When a competitor introduces a far-superior product, it forces the other players in the market to improve, instead of sitting on their asses not improving things because people are paying them anyway. Now that LTE is becoming ubiquitous, loss of CDMA would be less of an issue. But any phone built without CDMA will not be able to fall back to 3G data in most areas of the world.

      If the people saying the U.S. should've adopted GSM had gotten their wish, our cellular data speeds today would probably be down below 1 Mbps. When a competitor introduces a far-superior product, it forces the other players in the market to improve, instead of sitting on their asses not improving things because people are paying them anyway.

      The contra to this argument is that differing standards forced carrier lock-in, keeping consumers stuck with a device that wouldn't work on other carrier networks, allowing them to it on their asses and not improving things because people couldn't easily leave the carriers they were on.

      Had the US adopted a carrier-neutral standard users could have easily switched carriers without buying a new device and device portability and consumer choice would have driven carrier improvements instead of consumers being forced to sit around and wait for a carrier to adopt improvements to their unique signalling.

      • by Anonymous Coward

        Is that why so many carriers offer great deals to people who want to switch, some going so far as to buy out the rest of their contract?

    • If the people saying the U.S. should've adoopted GSM had gotten their wish, our cellular data speeds today would probably be down below 1 Mbps.

      One doesn't follow the other. The adoption of one standard at one point in time does not prohibit a change in standard at a later point in time. My old Nokia brick doesn't have an LTE chip in it either, and it seems the USA is quite laggard when it comes to upping phone speeds, something which was rolled out in countries which were GSM only before it came into the USA.

      I hardly know where to begin. You're confusing standards with modulation techniques. You're also confusing GSM the standard (1991, TDMA, voice with GPRS and then EDGE) with GSM the "class" (which includes UMTS, HS(D)PA(+), and LTE). The latter is a set of standards defined by the 3GPP [wikipedia.org], whose scope now includes the maintenance of the original GSM standards.

      CDMA is a modulation technique (actually a "channel access method", basically a way to share the medium vs an actual encoding). Other modulation techniques are AM, FM, QAM, CODFM, and OFDMA (OFDMA is one channel-access version of OFDM - 802.11G uses OFDM with CSMA/CA instead). There's a "class" of standards built on IS-95 (you may remember it as cdmaOne) that includes CDMA2000, 1xRTT, and EV-DO. These did pioneer the use of CDMA for cellphones, but everything uses CDMA nowadays, and GSM (the lineage) has used CDMA (W-CDMA) since UMTS.

      The point is, in non-RF cellphone usage, the antonym to CDMA is not TDMA, but GSM. And GSM the lineage has very much won the standards war with LTE. Over 90% of devices in the world use GSM-lineage standards, including most Verizon and Sprint devices (which are right at home on LTE). Eventually the legacy IS-95 derived standards will be completely turned off and the US will have gotten over its weird not-world-standard fetish, at least for cellphones.
