Didn't know if this would allow them to turn up the transmitters on the cells due to the boost in capacity since they have a larger allocation/more efficient use of spectrum to cover more area.
    I do not expect CA to extend coverage at all.

    The only (semi-)cell-edge benefit I can see coming from it is if you are at the "edge" of a cell in the sense that you have a poor B2/4 signal and a decent B13 signal, but your phone keeps switching between B13 and a higher frequency band. In that case, CA might make your experience marginally better by allowing your phone to keep a solid B13 connection, and then add/drop the higher-band carrier as part of CA instead of completely switching between the bands.

    Verizon CA live!

    CA = Carrier Aggregation

    Verizon is implementing CA across portions of their network to combine 2 different LTE bands (i.e.: band 13 and band 2) into one "pipe" for better data efficiency and increased network performance. When CA is active, users typically see an increase in download and upload speeds*

    *These data speed boosts may be short lived if network capacity limit is reached due to more consumers utilizing the available spectrum.
    Your results may vary. Network performance differs per user location.

    A small point; the current version of CA does *not* affect the reverse channel, and hence upload speeds. I believe the reverse/upload channel is included in CA in a future release of LTE, though.

    Excellent post. It will be interesting to see if Verizon includes band 4 ( 20x20mhz channels) with bands 13 and or 2 soon.

    Maybe if you have a compatible Cat 6 device, CA can switch between B4+13, B2+13, and B4+B2. Maybe for those that have only cat 4 device, they can only aggregate B2 and B13 for 20Mhz pipe. At least in NYC.

    The current iPhone (6s / 6s+) can aggregate up to two carriers of 20x20 MHz each. So, I would expect Verizon to allow (depending upon market), any of the following combinations:

    13+2
    13+4
    2+4 (if you have really good signal strength, maybe)

    [There *may* be Android phones on the market that can aggregate up to three carriers, in which case you could see 13+2+4, but, as far as I know, these devices have not yet hit the market.]

    Do any of you know whether any current phones (iOS or Android) can aggregate FDD carriers with TDD carriers? This would be of interest to Sprint, particularly...

    To answer your bottom question, absolutely not. Unless you count devices in the laboratory

    I remember Milan showing a screenshot of the Galaxy 6 being able to aggregate bands 4+13 for 225mbps theoretical speeds. I hope he can chime in at some point.

    I'm thinking Verizon will probably aggregate all 3 bands on the network side ( where markets have 13, 4 and 2) We just have to wait for the devices to take advantage of 3x CA. Exciting times ahead for big red!

    He's too busy parading around how amazing T-Mobile is on Reddit and Twitter.




    But it's great that Verizon has finally launched CA! Now if only iPhones can get a working FieldTest app
    Apple iPhone X

    Verizon LTE B4+B2


    AT&T LTE B2+B17

    Come on, really? I have to admit that T-Mobile's Band 12 rollout, at least in my local area, has promoted them from "completely unworkable" to "a reasonable contender."
