    There are two more bands hidden within AT&T’s version of the new iPhone 5

    FCC testing documentation reveal there are two more bands hidden within AT&T’s version of the new iPhone 5: PCS and cellular. The thing is there are no networks at either frequency today that could connect to the device. Could AT&T be planning a massive network overhaul?



    There’s more to the AT&T version of the iPhone 5 than meets the eye. ExtremeTech’s Neal Gompa sorted through the device’s testing documentation at the Federal Communications Commission and found there are two more frequency bands supported in the North American GSM iPhone beyond those Apple revealed in its official specs.
    Those bands are cellular and PCS, which operators today use for their 2G and 3G networks. The revelation is surprising, though it’s certainly not suspicious. Except for Sprint, no operator is launching LTE on those bands, and Sprint uses a different iPhone variant than AT&T. Apple had no reason to include those bands in its specs because there’s no network this particular iPhone could conceivably connect to – at least not yet.

    Either AT&T has enormous pull with Apple, convincing to make an iPhone that work on networks years away from being deployed. Or AT&T is planning a massive reconfiguration of its networks in the next year, something akin to the major network overhaul T-Mobile is doing today.

    That is just simply awesome as it is future proofed just like their recent android devices. I was worried apple wasn't going to be able to do it.

    Awesome!!

    I think the emphasis is on *future* for sure though.

    These same bands are in the VZW iPhone, and I highly doubt they intend to start refarming anytime soon...more than likely, the chip just supported them anyway.

    Verizon's 3G network. ............................................ AT&T's 3G network.


    Verizon's 4G network.

    i agree. i never understood the notion to have three versions of the same phone. i did think that since apple said one chip that it has all bands. they just disabled.

    I believe it has to do with cost via options when ordering the qualcomm chip. Apple doesn't want to pay for CDMA capabilities for phones destined for 3GPP networks etc.

    Here is a link with all the bands assigned for LTE:
    http://www.apple.com/iphone/LTE/
    Note that Band V (850) is the same as Band V (850) used for GSM/UMTS, but Band XXV (1900) is not the same as Band II (1900) used for GSM/UMTS.

    The difference between the two 1900 band designations is PCS G support for LTE mode.

    PCS represents the frequency range around 1900 MHz. DCS represents the frequency range around 1800 MHz. Different wireless technologies may exist in these frequency ranges. These include CDMA, GSM, UMTS, LTE and others.

    May I suggest reading Anandtech's article instead so you can clearly understand why there are 2 and probably 3 extra LTE bands in there: http://www.anandtech.com/show/6295/w...-svdo-support-

    Basically the Transceiver used that supports up to 5 LTE bands can use existing RF paths from WCDMA, and with right PA's and tuners you get to use those bands on LTE.
    I doubt that AT&T requested anything here, it's probably just the practicality. Also I suspect that LTE Band 1 (2100Mhz since it's already there on WCDMA) is present as well, which is used in Japan, but FCC doesn't test frequencies not used in the U.S so it's not listed on FCC site.

    Can someone break down what frequencies AT&T Verizon sprint are using for lte ? I know Verizon uses 700 850/800 1900. Sprint uses 1900 and 800 and I think 1600 or it needs approval. And AT&T uses 700. And tmobile will use 1700. Am I correct or did i mess up somewhere or leave something out ? Thanks !

    The link I posted from the Apple website shows the bands used by each carrier. The second link in the same message shows what frequency ranges are used for each band. Simply saying "700" is insufficient since that frequency range is allocated to multiple bands.

    PCS G is a small expansion of the PCS band, phones need to be designed to look into that frequency range.

    AT&T's original plans were to use 700mhz and AWS for LTE. Judging how their latest incoming phones have passed through the FCC with LTE support on 850 and 1900mhz....it looks like they will be using those bands as well in the future.

    Wouldn't it take awhile for them to free up space for LTE on 850/1900? Also, isn't the iphone 5 the only device so far to even have that band on it? It could also mean that that's the chipset that Apple put in the phone, since the phone will work in Canada, and other locations. Might not have anything to do with AT&T.
