    Band 13 is finally available in some sites outside downtown Vancouver.

    Nice find!
    I could only see it available from the Heritage Mountain, so it seems to be quite rare:
    Uplink Frequency 784.5 MHz
    Downlink Frequency 753.5 MHz
    EARFCN 5255

    Its even harder on the iPhone. Luckily it seems priority on this band is higher than B17 and B15. However the deployment was only on this one site which makes no sense at all.

    Most likely just a test site.

    I was able to lock to it with NSG on my Nexus 6P and that was the only site that I saw.

    EDIT: Looks like I mapped 2 sites in Tsawwassen as well with B13 back in April but didn't notice it.

    I did some more driving around and I managed to pick up the following B13 sites:
    - 3 sites at UBC
    - 2 sites on Sea Island
    - 1 site on Mitchell Island

    Seems like its a full deployment of band 13 then. Wonder why it took so long. Those multi-band antennas they use should support band 13.

    It's quite a strange deployment so far, but it could just be trying to improve areas with weak coverage first.
    It seems to be focusing on coastal areas only so far, whereas all their previous deployments seem to have focused on downtown and expanding outwards.
    I did a full loop around Vancouver proper to get those results.

    I was picking up cells 110/111 and 120/121 off the Pacific Coliseum yesterday. Bell SIM in Cat S60. Wish I could pull EARFCNs but I haven't found any way to enter service mode on this phone.

    It seems B7 is now spreading eastwards of downtown finally.

    If there is a 7.0 upgrade or if you root it, you can see the earfcn.

    Telus launched the update for the S8 to support 4CA. I assume it probably enabled 256QAM.

    The four bands are B2, B4, B7, B7. See here on Bell forum:

    I've noticed Bell/Telus have made the same mistake as Rogers and made B7 very high priority. As a result of this, it'll hang on to B7 until the RSRP is very low, and end up completely losing LTE signal and going back to B17 when it rescans. Not only does this make data extremely slow, but it causes significant battery drain.
    This wasn't the case when the previous B7 primary carrier was used, but was introduced with the new B7 primary carrier for 4CA. I am hoping they will fix this, as I've had to resort to disabling B7 on my Rogers device since I miss calls and have very poor battery life.

    Seems like they somewhat solved the above issue, but B7 is still going way too low before switching to B30...

    My local tower was upgraded a few days ago (to add B7). So now it has a grand total of 2,4,5,7,17,29, and 30.

    However, I've noticed that I am never able to trigger 256QAM on any of the bands. I know the phone supports it, as I can trigger it on Rogers on B2/4/7.
    Is 256QAM is only enabled in certain areas of Canada? Not in Vancouver? Seems strange 4x4 MIMO/TM4/etc. is deployed but not 256QAM.

    It's not enabled everywhere yet. What's the eNB ID and Cell IDs? I'll take a look.
    Want to learn more about how LTE works?
