I just noticed that eHRPD is back on in San Jose today. Also, the tower close to Santana Row has been broadcasting 800Mhz all week and now it looks like LTE as well. Hopefully things are picking up steam in this part of the market

Look what popped out of the ground the other day, could the recent rain we had have led to this? y2edynuv.jpg

Seems like the old water tower may no longer be the sprint cell site. Can't wait for it to be completed. This is in Gonzales, CA.

What is that?  It looks like a doppler radar site.

This is what it is. Although this picture is a bit old as well. If you guys want up an updated picture, I can get one. Right now that water tower looks crazy. Has a giant scaffold and being repainted.

Will let you know later today, when I'm in the north part of San Jose.  What device are you using, and where are you trying to catch the signal?  I'm curious as to what practical effect the new 800 CDMA signal will have on my day to day use.

No 800 on my drive to work or at work.  I've been on band 25 the whole time.  I'm on an iPhone 5s and am in an area where 99% of the towers are now 800 CMDA accepted.  Based on info in the map updates thread, it seems I'll get 800 only when there's no 1900 available...

I believe that iPhones prefer 1900 (if available) over 800.  Other phones simply prefer either 800 or 1900 depending on what they're currently / last connected to.

 

You're right.  Getting CDMA 800 on an iPhone in an urban area is tough to impossible.

Try going deep in a building.  Might help  ;)

 

Doesn't help for me...though I do get a weak 1900 signal so it must take zero (or close) 1900 signal to have the phone switch to 800.  I don't care which I'm using but with all the talk about 800 making things better indoors, it's a bummer that I'm not seeing it.

On an iPhone, it will not begin to scan 1900 until you completely lose a 1900 signal and then rescans all the 1900 channels to make sure there is no 1900 available.  After a 1900 rescan, it will then scan 800.  It is pretty hard to get CDMA 800 on an iPhone.

Does the iphone have similar behavior for LTE800?  Or is it network controlled?

Robert,

 

Thanks for the response.  Does this mean that iPhone users will benefit from 800 only when in areas with truly no 1900 coverage such as more rural areas or very deep inside a building (so basically we will roam less)?  It sounds as if 800 won't even help iPhone users with dropped calls, if the phone won't look for 800 until 1900 is completely lost.  Is there some other benefit for iPhone users that I'm missing?

PRL's only control scan behavior for CDMA.  For LTE it is network controlled regardless of device type.  We have already had a member in Wisconsin report being able to connect to Band 26 on an iPhone even while they were within Band 25 coverage.

Yes, this pretty much sums it up.  An iPhone user will get the benefit of 800 when they go outside of 1900 coverage.  However, once an iPhone gets on CDMA 800, it would likely stay there until it loses an 800 signal, the device is rebooted, airplane mode is cycled or the PRL is updated.

Got it.  Thank you for the info.  It's a bummer that they program the iPhone this way...

Well....That's just annoying. At least LTE is network controlled so Ill be able to get data inside. Most of my friends have iPhones so I can always just make a FaceTime audio call if I have crappy voice. Thanks for the insight... This seems to be  a very big question that a lot of people are asking, including me. Maybe it should be an article? OR is it already?

I don't think it's really just a choice by Sprint.  In my mind, it is either a device problem and they are working on a software solution for it.  Or Apple has requested that 800 be a low priority until 800 is more prevalent.  So the user experience is not hindered.  It is actually better to be on a cohesive 1900 network than a patchy 800 network.  It may change in the future.

When you say it's better to be on a cohesive 1900 network than a patchy 800 network, does that mean that the phone can't easily hand off between 1900 and 800 so it's not the same as any tower hand off?  In that case, I see the point.  If not (i.e., if the phone can hand off between 1900 and 800 interchangeably), then why not just make them the same priority?  Anyway, it will be interesting to see what happens with this.  Given Sprint's investment, and given how many subscribers use iPhones, I would think they will also invest in the software solution (if it's a device issue) or push Apple (if that's the issue) or come to their senses (if they're the ones programming the PRL in this manner).

A handoff between 800 and 1900 is technically possible if both networks are tied together at the same MSC cohesively.  But even in an ideal network set up, it is still a hard handoff and will have a much higher call drop rate than handing off between cells in the same CDMA band class.

 

Up until the 3G network is complete on all sites, both 1900 and 800, I don't think we will see a satisfactory handoff scenario between bands.  And this could be a driving factor with Apple.  Apple certainly doesn't want the perception that it is their device that is the problem.  And it's conceivable if someone moved from a Sprint 1900 only device and purchased a Sprint iPhone and then started dropping all over the place that they may conclude the problem is the iPhone since their previous device worked fine.

 

I don't know for fact, but I really feel Apple is the one that has pushed for iPhone PRL's to push CDMA 800 only as a last resort.  If I am right, then a new PRL will come out likely by Mid 2014 that will change the priority for CMDA 800 for iOS devices.

Thanks for the response.  Given the handoff issue, that makes sense.  And in this area, I go from the part of town where I live, where Sprint hasn't done much upgrading (many brown dots on the map and several white ones), to the part where I work (95% NV and 800 capable)...that would result in dropped calls (though I already get TONS in the first place).  Your suspicion would make sense for the South Bay market, which is where many of the Apple decision makers must live.

    • On Reddit, someone asked (skeptically) if the US Cellular buyout would result in better service.  I'd been pondering this very issue, and decided to cross-post my response here: I've been pondering the question in the title and I've come to the conclusion that the answer is that it's possible. Hear me out. Unlike some of the small carriers that work exclusively with one larger carrier, all three major carriers roam on US Cellular today in at least some areas, so far as I know. If that network ceases to exist, then the carriers would presumably want to recover those areas of lost service by building out natively. Thus, people in those areas who may only have service from US Cellular or from US Cellular and one other may gain competition from other carriers backfilling that loss. How likely is it? I'm not sure. But it's definitely feasible. Most notably, AT&T did their big roaming deal with US Cellular in support of FirstNet in places where they lacked native coverage. They can't just lose a huge chunk of coverage whole still making FirstNet happy; I suspect they'll have to build out and recover at least some of that area, if not most of it. So it'd be indirect, but I could imagine it. - Trip
    • Historically, T-Mobile has been the only carrier contracting with Crown Castle Solutions, at least in Brooklyn. I did a quick count of the ~35 nodes currently marked as "installed" and everything mapped appears to be T-Mobile. However, they have a macro sector pointed directly at this site and seem to continue relying on the older-style DAS nodes. Additionally, there's another Crown Castle Solutions node approved for construction just around the corner, well within range of their macro. I wouldn’t be surprised to see Verizon using a new vendor for their mmWave build, especially since the macro site directly behind this node lacks mmWave/CBRS deployment (limited to LTE plus C-Band). However, opting for a multi-carrier solution here seems unlikely unless another carrier has actually joined the build. This node is equidistant (about five blocks) between two AT&T macro sites, and there are no oDAS nodes deployed nearby. Although I'm not currently mapping AT&T, based on CellMapper, it appears to be right on cell edge for both sites. Regardless, it appears that whoever is deploying is planning for a significant build. There are eight Crown Castle Solutions nodes approved for construction in a 12-block by 2-block area.
    • Starlink (1900mhz) for T-Mobile, AST SpaceMobile (700mhz and 850mhz) for AT&T, GlobalStar (unknown frequency) for Apple, Iridium (unknown frequency) for Samsung, and AST SpaceMobile (850mhz) for Verizon only work on frequency bands the carrier has licensed nationwide.  These systems broadcast and listen on multiple frequencies at the same time in areas much wider than normal cellular market license areas.  They would struggle with only broadcasting certain frequencies only in certain markets so instead they require a nationwide license.  With the antennas that are included on the satellites, they have range of cellular band frequencies they support and can have different frequencies with different providers in each supported country.  The cellular bands in use are typically 5mhz x 5mhz bands (37.5mbps total for the entire cell) or smaller so they do not have a lot of data bandwidth for the satellite band covering a very large plot of land with potentially millions of customers in a single large cellular satellite cell.  I have heard that each of Starlink's cells sharing that bandwidth will cover 75 or more miles. Satellite cellular connectivity will be set to the lowest priority connection just before SOS service on supported mobile devices and is made available nationwide in supported countries.  The mobile device rules pushed by the provider decide when and where the device is allowed to connect to the satellite service and what services can be provided over that connection.  The satellite has a weak receiving antenna and is moving very quickly so any significant obstructions above your mobile device antenna could cause it not to work.  All the cellular satellite services are starting with texting only and some of them like Apple's solution only support a predefined set of text messages.  Eventually it is expected that a limited number of simultaneous voice calls (VoLTE) will run on these per satellite cell.  Any spare data will then be available as an extremely slow LTE data connection as it could potentially be shared by millions of people.  Satellite data from the way these are currently configured will likely never work well enough to use unless you are in a very remote location.
    • T-Mobile owns the PCS G-block across the contiguous U.S. so they can just use that spectrum to broadcast direct to cell. Ideally your phone would only connect to it in areas where there isn't any terrestrial service available.
