  1. Sectors 07/08/09 sound like the L1900 found in Los Angeles, so I assume this to be an Ericsson market.

     

    From what little I hear, T-Mobile is getting pretty aggressive with selective resource block shutdown to accommodate an 'in-band' GSM channel within the LTE carrier.

     

    Would be very interesting to see what E/U/ARFCN's you could pull out of it. Especially given the limited PCS holdings in that market.

     

    That would also put T-Mobile at 60 out of 70 MHz usable spectrum devoted to LTE, which is pretty insane.

    Can confirm all of this.

     

    Can you query the remaining UAFRCN too? And a couple GSM ARFCNs?

  2. Which part in the photo is the Nokia Flexi Zone "Mini-Macro" 2x20 W BTS?

    I'll be back for a cleaner shot. It's tough getting a drive by shot from the passenger seat on the freeway.

     

    Look near the middle left for the white unit. You can see a sliver of another unit on the right side also.

    Bingo. Only thing not spray painted.

  3. Maybe this is completely unrelated, but I wonder if they'd use a standalone "private" channel to provide backhaul to all of those new Mobilitie small cells?

     

    Does it work that way... is there a way to control what device can authenticate by carrier?

     

    That would make sense to me. Have to do some more math to figure out all the available BRS+EBS to see where they could shove more carriers.

  4. Some fastback action in LA

    Do you happen to know if Crown Castle owns the site, or the City of Los Angeles?  There was a vault for the site that was marked "Crown Castle".

     

    Owned by the city and long termed lease by Crown Castle who in turn leases it out to generally Verizon at the moment.

  5. Hmm. If they snagged all of the Cavalier, they're gonna be able to seriously compete in Charlotte and NC in general. They already have fantastic site density (they are very spectrum-constrained in Charlotte, 10Mhz FDD in PCS and 15Mhz FDD in AWS with no room to grow) and continue to add sites for capacity in areas seeing development. Downside might be permitting. All of their racks appear specifically fit to hold two AIRs and nothing else, so most sites would require entirely new racks for a new 700 antenna.

    It was not a problem here across LA and surrounding areas with updated racks. Also note there are low-band compatible AIR21s for an even swap.

  6. This looks like a small cell setup that Sprint has used. There is a VZ small cell about a block down the road so I dont think VZ would space them so close.

    What does everyone think?

    Looks similar to AT&T (or even Verizon) DAS gear. The Fiber to RF box is mounted below.

  7. Hey AJ...  Can you divulge a hint?  Is it due to placement of the antennas internally? Using a completely different antenna from the smaller handset?

     

    If I am reading it correctly. The following US LTE bands perform better for each model as follows

    6S Plus: B4, B30

    6S: B2, B5, B7, B12/13/17, B25, B26/27, B41

    edit:Looks like there is a different CDMA model too:

    edit2: AT&T getting their own model?

    Yup.

     

    AJ

     

    Bummer. Samsung was one of the only ones which included the LTE CA pairs in the main doc other than LG. Even Motorola started including it in some of their docs. Can we petition to have the FCC "test" and "certify" the LTE CA pairs (so we can see of course)?
