    This is not done per site or per region/area. The optimization team modifies tilt/power on a per-sector basis based on the drive test data they get. In areas where satellite signal is weak, XM band-stop filters do not have adequate rolloff to tolerate the significantly more powerful WCS signal, since the guard band can be as low as 2 MHz.

    The 5x5 B30 carrier @ 9840 is used in certain areas to prevent interference with Sirius XM.

    Nice! It came on in Chicago last week too.

    Multibeam antennas for massive capacity. The MatSing ball is the really impressive antenna here. Those have 48 independent cross-polarized beams that are 6 degrees by 6 degrees arranged in a 12x4 (horizontally by vertically) pattern.

    While that would be nice, it’s slowed down deployment in certain residential areas around Seattle where wooden utility poles are the only/best option today. In some cases, they’ve gone with lower masts on small grocery stores which really aren’t ideal (due to much higher clutter loss).

    Just heard back - this is a rule of thumb nationwide. Not sure how strictly other markets are following it but the team here is pretty adamant about it.

    At least in the Washington/Idaho/Montana/Alaska market, Dish is not using any power lines or utility poles. They’re exclusively going with rooftops and existing tower structures.

    Big shoutout to Mike for getting this one done - this will be huge for the quality of data coming into the nationwide database!

    NR carrier aggregation (600+2500) will be going live in Chicago this month!

    If you're a nationwide database user, add you username to the beta crew settings menu!

    The PCS G block will be converted to n25 when Sprint LTE is sunset.

    That’s awesome - I didn’t know T-Mobile was using this equipment. Here’s a bit about fast roll off for anyone interested: https://imgur.com/a/Hu73NAb

    Moved BETA feature discussion to the Premier Sponsor's "Nationwide signal check database" thread!

    Not super familiar with the radios, but those JMA fast roll off antennas are probably the nicest antennas on the market today.

    CBRS!

    Thank you! I would be porting to AT&T today if it weren’t for this!

    I went to three stores that had Sprint SIMs in stock, none of which could activate one for my iPhone. I also tried calling in twice as well as speaking with someone on online chat. In every instance, I was told they couldn’t move me back or that the system wasn’t letting them activate my device. While it may be possible to go back, they are definitely not making it easy. And customers like me (who depend on their phones for work) cannot deal with dropped calls and EDGE in the time it takes to figure it out.

    Just a heads up for anyone else thinking about making the switch to TNX - I tried for about two weeks and it does not appear you can go back if you don’t like your service with TNX. I would strongly recommend staying on TNA for anyone who is hesitant/unsure.

    The Sprint site at 520/202 was decommissioned a few weeks ago. Everything was pulled off the pole.
  20. RAvirani
    This!
  21. RAvirani
    Yes. If AT&T broadcasted B26, they could run a 15x15 carrier. B5 is limited to 10x10 per 3GPP spec.
  22. RAvirani
    B5 doesn’t support carriers larger than 10x10. B26 supports up to 15x15, but many AT&T devices don’t support it. Plus, that wouldn’t entirely solve their problem.

    I added in a few of the surrounding sites to paint a more wholistic picture of how I would set up the network in the area using T-Mobile's existing sites (these are using my sector alignments/downtilts/TMA configs/etc, not T-Mobile's). PCS RSRP: PCS Sectors: PCS SNR: I actually like the site in Kingsgate to the northeast. Verizon has ubiquitous AWS in the area from that monopole and the site on Evergreen hospital, and it seems the projections mirror my experience there. It’s crazy how much more they push their sites than T-Mobile. Regarding the residential areas to the northwest - I see your point. While RSRP levels look nice, SNR isn't the best - mostly 16QAM. That being said, I think SNR is much more important in commercial areas than in residential areas because data usage tends to be much higher in commercial areas. In residential areas, people are much more likely to be on wifi. I think dropping a site on one of the stadium lights at Juanita Highschool could probably close the SNR gap. Maybe T-Mobile could trade a site there for the McDonald's site. Electrical downtilt would have to be increased on SE03208A/270 and SE01196F/0 to accommodate the new add.

    Generally speaking, Verizon tends to split eNBs (disable lowband-midband carrier aggregation) on sites with high lowband usage. I’ve noticed that as infill sites come online and density increases, a lot of previously split eNBs have been unsplit.

    This is getting sort of confusing, so here are all the imgur links: Ideal optimization (my opinion): https://imgur.com/a/9x3UbVK Current network: https://imgur.com/a/JTW2JXM Current network without McDonald's site: https://imgur.com/a/yWafnon Current network without AT&T colo: https://imgur.com/a/xG9Ix7b
