Those of you who are having issues with band 41 -- are you having issue with Clearwire LTE or with 8T8R equipment?
-
If you have an Airave 2.0 or older, you should be fine. If you have an Airave 2.5 (the one with the internal, detachable GPS unit), it broadcasts a beacon on 1x 800 and will probably interfere.
-
If you have band 26 coverage, you undoubtedly have 1x 800 voice coverage and don't need the Airave anymore. I say unplug the Airave and test it. If that doesn't work, call Sprint and yell.
-
Sprint's official stance is that you need to disable LTE to use an Airave with a tri-band device.
-
No, but there's an updated radio interface layer (RIL) library in that last one.

I wouldn't recommend this. Google Voice integration itself causes me to miss plenty of calls. I've had a ticket open about it for months. They got some good data about it today though. Five of the recent examples didn't show up in my local MSC or the Google Voice switch.

How to Spot Sprint 8T8R TDD-LTE RRHs (Samsung)
JWMaloney replied to lilotimz's topic in Equipment Spotting
If a site is specifically a GMO, it has legacy antennas, so it can't support any 800 MHz services. But that doesn't mean sites can't have RRUs mounted at the BBU cabinets and NV capable antennas (in which case they wouldn't be a GMO). At those sites, all bands should be possible. As far as I know, you usually only see something like that in places like rooftops or small/stealth sites (like "flagpole" sites) like this one from the in-progress thread: -
In mature band 26 areas, I'm seeing band 26 used more frequently and more correctly, with proper hand-offs between sites. On sites with eCSFB issues on any band, I'm seeing a greater tendency to get pushed back to 3G.

How much is a Max-Discount Framily Bill, w/Fees?
JWMaloney replied to burnout8488's topic in General Topics
It varies even by city because of municipal fees and taxes. -
The hub he was referring to in that video also showed up on the Network Vision map a while back: I confirmed it with permits dating all the way back to 2007 for all 4 major carriers when it was constructed, and with Street View imagery of the hut/cabinets themselves.

Brick wall: Sprint eChat and eCSFB issues
JWMaloney replied to burnout8488's topic in General Topics
Check your PM. -
I believe this may be related to the recent announcement that Verizon has secured VOIP interconnects with Sprint and T-Mobile. This may have something to do with inter-carrier HD voice. It may also be related to some sort of cloud synchronization of services and/or storage.

No

My thoughts after a full day of testing and not losing LTE at all on launched sites:
-
ART, hands down.

RSRP (dBm) alone is a pretty useless measure of a modem firmware; there are plenty of other important numbers on the engineering screen too. What really matters is the performance on that firmware. I said this before the 4.4.3 update was released -- my own testing shows that, while the .17 radio shows higher dBm readings on LTE, the .23 radio connects to LTE in less places because of poor fringe performance. That said, I upgraded last night directly from the .23 radio, and I can tell you that the new 2.0.50.1.13 radio is absolutely giving me much better band 26 performance. I previously found it impossible to reliably hand off from site to site while connected to band 26 (the device would drop to eHRPD instead and park there for a long time); now I'm seeing my device idle on band 25 and correctly move to band 26 either when necessary -- either when the cell site tells it to (for capacity) or when approaching the edge of the band 25 cell (for coverage). And I'm actually seeing hand-offs across band 26 sites now. I'm also seeing the device grab onto band 26 in more places than before (for instance, in elevators and parking garages) where it would previously give up and fall back to eHRPD. And on a fringe signal, I'm seeing better speed tests. At home, where I have a good signal on either band, I'm seeing better behavior -- the device will camp out on band 25 while I'm on Wi-Fi, and it will immediately move to band 26 when I disable Wi-Fi. I tested that several times, and it moved after every toggle with no issues. And even at my desk at work, where I get a poor signal, I've been on band 26 all morning and haven't dropped to eHRPD once. Previously the device would move between band 25, band 26, and eHRPD all day in this spot. I'm starting to think some of you just have defective devices.

You may be on an older PRL which scans for 800 first.

"Is America getting over its smartphone subsidy addiction?"
JWMaloney replied to COZisBack's topic in General Topics
Everyone tends to forget how many people rushed out to buy the $600 unsubsidized iPhone when it was first released. I can see prices decreasing, but not by much. -
I do, because it's about time we have simultaneous voice & data. And there's no reason it should be less coverage, as the calls should hand off to 1x voice via SRVCC.
