Apple Patents Alternative To NFC 171

another random user sends word that a set of newly-granted Apple patents published by the USPTO includes an alternative to the near field communication (NFC) technology that has begun to pop up in mobile devices. From the article: "Apple has received a Granted Patent relating to techniques for triggering a process within a portable electronic device that identifies itself for purposes of establishing communications with another device that is in proximity. At the moment, NFC is the technology that's getting all of the attention lately in respect to making it easier for two mobile devices to share information. While Apple is likewise doing research with NFC, they're also working with an alternate methodology for which they've now gained a patent for. In accordance with Apple's newly granted patent, a method for network device discovery monitors a compass output in a portable electronic device. As the portable device and an external device come closer to each other, a magnetic field signature is computed based on the monitored compass output. A determination is then made as to whether the computed signature could be associated with or implies that a previously defined type of electronic device (with which a network device discovery process can be conducted) is in close proximity. In other words, as the two devices come closer to each other, their respective magnetic characteristics cause the compass output to change in a way that implies that a network device discovery process should be initiated between the two devices."

People with Android and other phones will have no problems but iphone users will be standing there poking at their tiny screen, wondering why their superior machine won't play with non-Apple world.

        USB power has a fundamental limitation - micro-USB connectors are only rated for 1.7 A. The USB charging spec maxes out at 1.5 A. That's right at the edge for today's phones and battery technology. Lithium batteries exist which can be charged at a 1C rate, and a 1.5 Ah battery is about what most smartphones have. It's more limiting for tablets, which have batteries which can charge faster than USB can allow.

          USB3 has charging standards which allow for much more power.
          I don't think any manufactures have added support for it yet though.

          Profile 1 - 5V @ 2A
          Profile 2 - 5V @ 2A or 12V@1.5A
          Profile 3 - 5V @ 2A or 12V@3A
          Profile 4 - 20V@3A
          Profile 5 - 12V or 20V at 5A (100W).

          I believe the idea around profile 5 is so laptops can drop the custom power connector and use a USB3 port instead.
          It makes things interesting if all laptop USB ports support all power profiles. You could charge one laptop from another and even make a figurative 'energy black hole' by looping the charge back again with another cable.

          • Profile 5 can be either 12 or 20? And is this somehow negotiated outside of negotiating which profile to use or is it just a crapshoot, one manufacturer chooses to implement 12 while another chooses 20? Why do standards committees always seem to pull this crap? Just make it either 12 or 20 and make that the only valid profile 5 standard! Seeing as Profiles 4 maxes out at 60W and 12V @ 5A is also 60W I would go with the 20V option for profile 5.

              iPad 3 is a power sucking monstrosity. The only reason Apple quadrupled the resolution was because of the scatterbrained design decision to let applications depend on fixed resolution. Exacerbated by the idiotic lack of hinting in Apple's font engine, so higher resolution is needed just to get equivalently sharp characters that Android gets with proper hinting. Oh, and the fixed resolution idiocy came back to bite Apple again with the iPhone 5 - forcing the funny looking too-long-and-skinny form factor just to keep the 640 dot display width. And letterboxing! Who was asleep at the wheel in the Apple's engineering department anyway? Well I'm not complaining of course. Strategy like this is the best and fastest way to transform Apple from a growth stock to a shrink stock. Which couldn't happen to a nicer company.

            • Even if we assume USB is incapable of powering stuff that needs more than 1.5A (plenty of ways around that), they could still use microUSB plus some charging solution on the iPad, to complement, not replace USB charging.

              Any physical limitation of USB is also present in the dock connector cable or lightning cable and connector. Apple's connectors aren't magical, just carrying more current than most people like to cram through them.

          Samsung's Micro USB connector on the GS3 has extra pins which, among other things, allow it to exceed the 1.8A maximum current on the standard connector. It is still fully compatible with ordinary cables, you just need a special Samsung one to charge at over 1.5A.

        NFC is already widely accepted in many parts of the world and a cross-device standard available in everything from smart cards to phones, so it isn't going anywhere.

        Apple's system seems to be much, much lower data rate at best. To be honest it seems more like a gimmick designed to allow users to do the physical action of bringing phones together like their NFC enabled friends can, but doesn't actually have the same functionality or data transfer capability.

      • NFC technology and PassBooks' technology are orthogonal to each other.

          NFC's more fundamental problem though is adoption, which is the same problem with this Apple standard. The proposed use cases for NFC are very broad - that is, it doesn't remove any requirements from vendors and end-point users it simply adds new ones. Just look at VISA and Mastercard trying to push those PayWave type systems - and they're the dominant global players in this market.

    • Except the patent isn't the same. There's no data being relayed over the magnetic field. Apple is just using the magnetic field to detect the presence of another device, not actually send any data stream. They use another protocol (likely in practice to be Bluetooth) to do the subsequent matchmaking and data transmission.

      Apple's process actually avoids stepping on this patent at all by not using the magnetometer for data transmission.

      Actually, this makes them infinitely compatible, since the iPhones rely on the magnetic signature of other devices to recognize them, possibly even without interaction from those devices. Passive recognition, in essence.

Differentiating between individual devices or makes/models, now that's a whole other can of worms. It may or may not be possible, but on this one, I'm leaning to go with you and say that such in-depth profiling is indeed impossible.

As an Android developer and as someone who is optimistic about NFC (not necessarily about payment NFC, but about the simpler use cases of NFC that do not require access to the hardware secure element). Whenever I speak to a potential client about using NFC, the conversation always gets steered to a way to make it backwards compatible for other devices.

    Okay, Apple is pulling a '90s Microsoft now. NFC isn't good enough cause they can't control it, so they just HAVE to make their own. Just like Microsoft did with WAV files, TrueType fonts, etc.

  • Sounds like it would use a fair bit of power if it has to do calculations the whole time.
  • >magnetic field signature is computed based on the monitored compass output

    In what way is this no 'near field communications'

  • Apple acquires patents from the AFC (American Football Conference) after talks with the NFC fall through. Apple just had to get a piece of the $10B American Football industry.
  • It's simple. If Apple were to use a standard NFC sytem, they would have to admit that the iPhone 5 actually isn't the be all and end all of smartphones. And even if they did, using a standard implementation would mean they couldn't act like they invented something entirely new that nobody had ever had or been using for one or two years prior....
  • Oh great. *This* will server consumers well: competing standards, a fragmented market, and many years delay in widespread adoption. Nice work, Apple.
  • Standards [xkcd.com]

It is easier to write an incorrect program than understand a correct one.
