  • More Details on Wi-Fi Chip Uncovered Inside iPod Touch

    A mysterious discovery has been unearthed inside the new iPod Touch.

    According to the San Franciso Chronicle, a Broadcom Wi-Fi chip was discovered during the dissection of the new 32GB iPod Touch by the makers of iFixit, a Web site founded six years ago to help people "tinker with their electronics."

    The full list of discoveries was chronicled earlier in our forums.

    The new Apple iPod Touch uses a Wi-Fi chip that can support the just-approved high-throughput 802.11n standard, though Apple apparently has not switched on the cranked-up wireless link. If it does, the iPod Touch (which is almost identical to the iPhone but lacks the 3G cellular radio) could support a 50Mbps data rate, more than twice that of the current 802.11ag radios used by the product family.
    Exciting, isn't it?

    Almost makes me want to disassemble every Apple device I own to see what other cool things may be hidden inside. But for now, I'll hold off.

    If you're wondering, the unearthed chip is the Broadcom BCM4329 - the first Broadcom 11n product designed for mobile devices. It's cutting edge stuff, and, apparently, its been in our midst for quite a while. If utilized, it could introduce a broad range of possibilities for the iPod Touch.

    The single chip combines 802.11n with 802.11abg, Bluetooth, and FM radio. It runs in both the 2.4 GHz and 5 GHz bands. The chip reflects the range of implementations available to chip and equipment vendors. The 802.11n technology exploits multiple-input multiple-output splitting a high-rate data stream into, today, two slower streams, each sent from and to a corresponding pair of antennas. It creates a kind of parallel transceiving capability, which dramatically multiplies 11n's capacity.
    Although the discovery of the chip inside the iPod Touch was surprising, Apple's use of the chip isn't - they've been employing 11n in their desktop products since 2007.

    What might Apple be planning for their mobile devices?

    From CNET:

    We don't know yet if 802.11n will be supported in the iPod Touch software, but at least the hardware's there.

      A) it would untether ipod users from wifi, ( mobile itunes purchases = more revenue)

      B) doesn't affect apple's IPHONE agreement with AT&T and opens opportunities to build partnerships with other carriers who might be interested in a NON phone product. (at the end of the day, it's all about ARPU for the carrier which apple could negotiate a share of, just like how they are pimping AT&T).

      C) I already mention UNTETHERED wireless which may not be the correct term since there aren't wires involved in WIFI, but you wouldn't be required to be in a hotspot area to take advantage of the full capabilities of an Ipod touch. - better still, you could buy a mobile hotspot device and set up a data account with a carrier which would be even more useful and provide access for your laptop and other wifi supported gadgets - but it is another thing to carry . ( in fact if those carriers were smart they'd start selling Ipod touch units alongside their wireless hotspot hardware ) A GSM Ipod would be good for people who like their phones to be phones and want their ipod to be their "palm sized computing device" - I had a 16gb 1st gen Ipod Touch but replaced it with a 16gb 2g Iphone that Im using with a data only sim, my phone is a blackberry 8900. and they are both on T-Mobile , unfortunately T-Mobile doesn't offer a 3g wireless hotspot device.

      it would also cannibalize iphone sales. An ipt with a sim is an iphone with no phone.app - also, this requires a baseband chip which means higher cost of production.

      From a business perspective this would be a bad decision. What apple is doing now is selling 2 devices that are essentially the same, but with a slightly different tweak in hardware. By doing this they are targeting 2 very large markets - the mobile telecom industry with their iphone, and their cash cow with the ipod market.

      If the Ipod is the cash cow, then a completely wireless ipod experience would only make the cow more fat. From a technology perspective, Apple certainly doesn't NEED to do this, it's actually better for wireless carriers that they DONT do this, it makes 3g wireless hotspot plans even more attractive. It will enable the carrier to pitch it as the multipurpose "do all" service to have. Connect your netbook, your IPOD, your Digital Camera , your E-Book (Maybe the next sony e-book device will sport wifi), If it's portable and can connect to WIFI, you can connect with a 3g wireless hotspot device ( don't leave your internet connection at home, take it, and the devices that connect to it, WITH YOU). This is the future of highspeed WIRELESS internet is about. The IPOD TOUCH could also evolve into a true POCKET MAC.

      there are many ways to implement a stand alone add-on that could give the IPT it's own internet connection. However I like the flexibility of a device that allows multiple devices to connect to it. The original POCKET PC form Compaq, ( the IPAQ) was designed to fit into a "sleeve" that gave it additional functionality, a few different versions were available. ( one had a flash card slot for adding extra memory, another had a wireless card slot ) so it's conceivable that a third party vendor or APPLE could in fact do something similar for the IPOD TOUCH, People have been talking about a joystick/keypad add on to make the IPT the ultimate portable gaming platform, why stop there, what about an adapter with a slide out keyboard? or one with that acts like a Docking station so the IPT can be connected and used as a desktop unit.
      so you can run you apps on a bigger screen and use a keyboard and mouse to control it?

      Truly the possibilities are endless, but at the end of the day the primary question any company would ask is, is it profitable? that's where it gets all fuzzy. I'm interested to see what CREATIVE LABS does with it's Zii processor and their Zii-Egg device which is running Android and Plaszma platform? Creative might actually be on to something, but it would take some genius product management to create a device that is super innovative while still being consumer-centric. strategic alliances with the right vendors and a fine tuned ear to hear what things would compel the market to take notice. It looks promising, but so did The Sega Dreamcast, HD DVD, BETAMAX, Minidisc, DAT, DCC, SVHS, Quadraphonic Stereo, DIVX DVD Disc systems, Super Audio CD, DVD Audio, The Atari Jaguar, Atari LYNX, Nintendo Powerglove, Act Labs Force RS driving wheel, the APPLE NEWTON, Steve Jobs NeXT computer, and last but not least, The Electric Car (oh wait, that really was a good idea on paper and in actuality and it appeared to be working 100% without fail, until the industry made them all disappear and pretended like it never really happened ). so yeah, back to the topic IPOD TOUCH+ wireless hotpot is a killer combo, no sim card slot required

      once again apple proves to be sneaky setting up to stay on top. If they uncorked there potential they would kill so bad
