    Telus 4 CA bands and bandwidth

    Has telus disclosed which bands they are deploying 4 CA on and the bandwidth​ on each?
    Are all markets already on 4 CA 700mbps?

    I doubt they would release those kinds of details. But you can get an idea based on the target speed of 700 Mbps, which would need 20 + 20 + 15 + 15 for a combined 70 MHz. All 4 channels would need 256 QAM enabled. All of this is assuming 2x2 MIMO.

    Does telus have 20 + 20 band 7? Then it could be B7 + B7 + B2 + B4, since in AB they only have 15 MHz on band 4 and band 2.
    Why don't they do 4X4 MIMO like TMobile?

    In Toronto where Bell's network is shared with Telus, there is: 20+20 B7, 20 + 20 B7, 20+20 B2, 15+15 B4, 5+5 B5, 5+5 B12, 5+5 B13 and 10MHz of B29.

    sooo...quite a bit of spectrum here. They probably give the maximum estimate based on whatever area they have the most spectrum in

    Yes, you got it. Though it's Telus 20 MHz and Bell another 20 MHz.
    4x4 MIMO is available on the network for some bands, but S8 doesn't support 4CA with 4x4 MIMO.

    Close, both B7 channels in Toronto are 20 MHz.
    Also don't forget 5 MHz B13.

    What I see in Downtown Vancouver, in terms of the best case scenario is:
    B2 20Mhz (4x4 MIMO)
    B4 15MHz (4x4 MIMO)
    B5 5MHz (2x2 MIMO)
    B7 20MHz primary (4x4 MIMO)
    B7 20MHz secondary (Not sure if 4x4 or 2x2)
    B17 5MHz (2x2 MIMO)
    B29 10MHz (2x2 MIMO)
    B30 10MHz (4x4 MIMO)

    All support TM4 from what I recall.

    Not all sites have 4x4 or all the bands, however. Mostly a few key downtown ones have the latest features.

    There is also 10MHz of B40, but it is being used for a completely separate network (most likely fixed wireless).

    Considering my S7 does many random 3CA combinations of the above that meet 3GPP specs, it seems to be fairly flexible in terms of what can be used.

    Do you know what BC and AB have?

    Now the 2nd B7 carrier is at EARFCN 2850 @ 20MHz, at least on a local site here in Vancouver. The change must have happend the last day or two.

    Seems like my Bell SIM is now using EARFCN 2850 as the primary B7 channel instead of 3350. Not sure if it applies to Telus SIMs as well (will have to test it out). Also appears to be a new CellID as well (120-129)

    Is the bandwidth different?

    Second IMT-E/B7 channel live in Calgary on 3300/2675MHz @ 10MHz (3150/2660MHz for the Telus 20MHz).

    Looks like Bell have block A and F, so we're stuck on 20+10 unless Videotron and Bell swap spectrums.

    What does Telus have in terms of spectrum in Calgary?
    Vancouver started off at 2900 10MHz but went to 20Mhz when it moved to 2850.

    Telus has a contiguous 20 MHz
