We believe Verizon is installing a ton of small cells throughout the Columbus Ohio metro. Amcferrin90 put a spectrum analyzer up to one and saw their frequency, but no Verizon users that I have asked have been able to get on them yet

Not to be pedantic, but what do you define as a ton? I'm legitimately curious about how much effort they're putting in to this.  :)

I would guess within the majority of all high density urban venues, and stadiums and large office complexes within the immediate vicinity

We have not mapped them, but we have seen at least twenty without really looking, with more and more showing up all the time. They are mounted on utility poles in neighborhoods and industrial parks. Installed by a one person crew with a utility bucket truck.  https://www.dropbox.com/sh/t0qot9w0jt2ix40/AADlqMcroKEsSQq9JTrcba_Ga?dl=0.  Amcferrin90 recalled they were using 736 to 756Mhz [746.5Mhz - 755.5Mhz, band 13 as per attachments below from amcferrin90].  I have seen them within a mile of a Verizon site.  They may be to be aiming for metro-wide coverage.  They generally don't need meters and run off of the city light circuits with a permit due to their low power requirements.  We also seem to have some variation with this type of equipment.

Band 13 downlink is 746-756 MHz, not 736 MHz.

Thanks.  I wanted to post a link to amcferrin90's work but have not found it yet. Amcferrin90 sent it to me: https://drive.google.com/folderview?id=0B8viExQFcZdaNjBjUEY1WE05UUE&usp=sharing

Wow! 20 without even looking for them? I hope Sprint ends up doing this with B41.

Yeah, typically sitting at a traffic light and you glance around and there is another one. You don't remember it from last time. Added details to some of the above posts. I think I saw one guy putting them up with a ladder. Have been too busy to stop and chat when I have seen installers. limotimz thinks each site should have a reach of about 1 kilometer. Any further info or speculation would be good. Obviously I am wondering if it might be part of their CA strategy.

Where does VZW have carrier aggregation capable band 13 infrastructure?  Most of it is old, non RRU, Release 8 infrastructure.

I was wondering that myself. Verizons press release was notable for not mentioning an upgrade to release 10.

They've announced Carrier Aggregation rollout for 2015, so Release 10 equipment is a must. It'll have to be a selective launch as there is absolutely no way that the entire LTE footprint gets the overhaul that quick.

 

I've been keeping an eye on potential 13+2 CA in NYC as that could be something that existing Cat 4 devices could actually attach to. There are still absolutely no signs of backhaul provisioning boost. Sectors are capped at either 80Mbps or 100Mbps, and three LTE downlink channels (10+20+10MHz) are all competing for that same under provisioned backhaul resource.

I totally get that. What I am saying is that for a press conference that was relatively heavy on tech details I was surprised that they did not specifically mention Release 10 equipment.

A growing number of them (and atts) are Rel 10/11 rip and replaces where they strip the entire legacy site down and rebuild with new Alcatel-Lucent or Ericsson equipment. Typically it's the oldest sites or the highest capacity sites that are being renovated first. 

 

So basically their version of Network Vision?

 

What happens to those sites in terms of customer experience? Site goes down for an hour or two, back up with new equipment broadcasting?

I think it's a bit longer than an hour or two. The guys I saw here were up there taking down antennas and putting new ones up for about 5 hours at a time. (I should specify that the Verizon stuff is on the second page of the linked thread.)

Takes about a week or two for the crew I talked to and observed.

 

They completely tore out the old coax jumpers, base stations, 9 antennas etc. Completely decommissioned the site and then pulled up hybrid lines for the AWS RRU + antenna (1) and then good old coax lines from the new base station to second antenna (2) which broadcasts LTE 700 and the CDMA stuff. 

 

6 antennas, 3 sectors, 3 radios, and 1 new base station.

So what happened in the meanwhile for customers? Was the legacy site still up till the last minute?

 

I really am curious to see what the other carriers are doing in terms of their network upgrades. Always good to learn.

Adjacent sight took over with CL850 CDMA and LTE 700 reaching a tad over. There's also a VZW pico cell mounted on a light post in front of the tower that serves a couple clustered industrial buildings. The other side of the road was a local airport which gets connections easily from adjacent sites further away because it's a wide open and flat area.

 

The second crew (from the same company) I found working on it was at a local school tower which had a well used football / soccer stadium right next door. That one removed 6 old antennas and replaced with 6 new but had two RRUS12s per sector this time around. Took about 2 1/2 weeks. A week after they left, Sprints and Samsungs local contractor came by and installed the NV equipment and used the same boom lift the other contractors happily left behind.

I love it, probably scheduled that way to save money.

At this point Release 10 equipment isn't anything to brag about. It's a basic, minimum system requirement for operators that wish to activate LTE-Advanced features on their network.

Also, historically Verizon's never been the most "vocal" operator when it comes to their equipment infrastructure. Their PR loves to dumb it down as much as possible.

Getting details out of them is like pulling teeth sometimes...

That's why I drive right up to the local cell site when there's work going on and talk to contractors who work for them. :P

 

Who knows what might happen. Maybe you'll even get a mini tour of the leased area and watch / help install the DUS/DULs in the cabinets. :)

Hopefully new phones introduced next year (possible Galaxy S6 and iPhone 6S/6S Plus) will help drive forward Sprint's Spark network with B41 Carrier Aggregation

Nope, not the presumed Samsung Galaxy S6 nor the expected iPhone 6S.  The earliest that the Snapdragon 810 (MSM8994) will make it into consumer handsets is sometime in the second half of next year.  An LG G4 and a Samsung Galaxy Note 5 are potential candidates.  And you will not ever find a Snapdragon chipset in an iPhone -- because Apple uses its own ARM based processors.

The article states that "The Snapdragon 810 processor with Category 9 support is anticipated to be available to our customers in early 2015" so there is a possible chance Samsung could include it in their new flagship device in a chance to put a one-up on the iPhone 6/6 Plus.

 

I never said the iPhone would incorporate that chip into it although I can see the confusion in my wording. I was merely stating that the technology is being introduced and the big phone makers will be able to release new devices with the Carrier Aggregation capability.

''our customers'' = companies like Samsung, LG, HTC, etc who can then start utilizing the finalized commercial products for phones early on in development or not yet in development.

Cat 9 devices will not be out til late 2h 2015.

Also, 810 is mentioned in some of the M9 rumors.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
