No SVDO nor SVLTE!!

So it turns out that (according to the verge) the cdma versions of i5 will not be able to use data and voice at the same time, regardless of 3g or 4g. One user on the apple forum explained why this may be the case; in order to save on space and battery consumption, apple (foolishly) opted for a single radio for the modem. So although the 9615 seems to support every modern relevant protocol we would use, It appears that only one mode can be active at a time.

 

Quite simply, that is trash in my opinion...we should be moving forward, not backward.

This is what happens when you have a limited number of SKUs for every market in the world. You have to make compromises like this. The Galaxy S3, EVO 4g LTE, and Photon Q were all made specifically for Sprint's network and exactly the needed antenna design was put in them. With the additional LTE bands going into use for all of these networks, Apple will have to follow suit with their next phone and customize for each carrier.

 

Unless of course some magical technological changes happen in antenna design.

 

With the reasoning that this user came up with, however, At&t wouldn't be able to do simultaneous LTE and calling either, until they implement VoLTE or something similar.

Since the iPhone will likely support VoLTE at some point, the real onus should be on carriers to accelerate to VoLTE.

 

Most users I know on Sprint and Verizon don't really care, and even those who have LTE don't use SV-DO or SV-LTE.

 

Again, a case of the tech geeks being disconnected from the rest of the planet. I suspect Apple wants the industry to move to VoLTE, as it is way more in line with what they want for the future.

If this is true then what a shame. Its sad that the most profitable company in the world couldn't invest a few extra dollars per unit to give their customers a better user experience.

Most users on sprint/verizon don't really care because its something that was never available(not until recently) based on the type of technology. At the same time someone coming from tmobile/at&t to sprint/verizon would more than likely notice it. It's important enough for att to make commercials about the fact that you could do data and voice at the same time but you couldn't on verizon. It may not cost apple anything at all but it will definitely cost the carrier.

If Apple is willing to make all their accessories vendors retool their manufacturing then don't be surprised if they do something to the detriment of their carriers.

I personally changed from a Galaxy Nexus to an S3 because of this and the obvious better battery life. There were just too many times I needed to use both voice and data but was unable to. I believe another reason Apple may have done this was for battery performance.

I do agree it is rare I use it since I don't talk on the phone much but it has been nice to use a couple times I needed it.

I guess I won't get an iPhone 5 then. What a horrible and stupid thing for them to do. I was really looking forward to using iOS again. :cry:

 

:o WAIT WHAT? I can't believe what I just read!!!!!!!! :o

It has also been learned and confirmed by Sprint, that iPhone 5's hdvoice is incompatible with Sprint's hdvoice because iPhone 5 uses wcdma for it's hdvoice in which Sprint uses cdma 1x advanced. So no hdvoice in the U.S.A. For iPhone 5.

Is Josh getting a divorce?

 

;)

Josh is just really angry at Apple for their stupidity at making it impossible for the CDMA iPhone 5 to have SVDO or SVLTE! Their is no rhyme or reason for this crap. Now back to pursuing my Photon Q or Galaxy S 3 I guess. :(

No, Apple is the dark side when it comes to phones. So you think the GS3 is better than the Photon Q? Of course, I think so too.

Was poring over FCC docs today in preparation for an OET article like what AJ has done for the Eclipse, S3, etc., similar to what I'm sure The Verge did.

 

In the few thousand pages of material that Apple submitted, SVDO and SVLTE are not mentioned. What is mentioned is that only one technology, on one antenna, will be transmitting at any given time. The charts that go along with this note are confusing at best (they look like information overload until you realize that the data therein is largely redundant) but seem to indicate that you can use, at best, one cellular tech and one WiFi band at once. So if you're on a CDMA + LTE network you can't do SV-anything without a VoIP app, and on a WCDMA + LTE network you're limited to WCDMA if you want data with your non-VoIP voice.

 

Why have I not mentioned VoLTE yet? Because it's explicitly not supported.

 

On the plus side, FaceTime over cellular! Yay! Wait...do I hear crickets? Hmm...okay.

Yep, you hear crickets, or people loading guns to shoot Apple for this devious act.

Face time over cellular technically worked on previous phones too.

Yeah, when cellular data service is decent it works great. My friend and his brother have Jailbroken iDevices and they like the whole Facetime thing.

 

Yes I know, I was just being sarcastic.

Yes, I know you were, but unfortunately it's more true than it is false.

Clearly, most don't care though.

 

Generationally, people my age and younger don't even use the phone to talk much. HD Voice could change that, and I think my disappointment is in not having clear standards for the industry that help accelerate this process.

 

The more I read about VoLTE, the more I realize it's a mess.

    • Update just showed up for both of my phones. So far I don't notice any difference, LTE TA is still reporting as 0, I was hoping the new routine might fix that. I sent a diag report from both phones in case you need any of that info. I'll let you know in a day or so if its crashing as frequently or not. 
    • A new SignalCheck Pro beta release is rolling out now, and should become available on Google Play shortly! Some notable changes: New "swipe to refresh" -- flick down on the main screen, and the data will "refresh" -- I put this in quotes because it will *not* force the modem to be polled (that's unfortunately not possible), but it will 'wake up' the app and display the latest information if for some reason your screen did not automatically update. I am still working on improving this. New cell identification methods for Android 12+ devices -- new routines are available in Android 12 and this is my first attempt at implementing them. I have not seen any changes positive or negative on my Pixel 6, but hopefully someone sees improvements. I will continue exploring these methods and adding new features as I get them working. Location service auto-restart -- if your location has not changed in 10 minutes, the background location service should restart itself. This is a work in progress that I intend to optimize during beta testing. Missing/invalid TAC values included in web uploads -- this will need some testing, because I can't replicate it myself. The option to log cells with missing TAC must be enabled for this to have an impact. Feedback welcome as always!
    • Another converted keep site: Sprint eNB 9436 -> T-Mobile eNB 895067 (40.60777246698788,-74.16199692361377) Looks like they're using the FFVV-65A-R2-V1 here, as well!   Edit: Also, I know this technically isn't NYC, but here's a Jersey City conversion. Not 100% sure on either eNB. Sprint eNB 105863 -> T-Mobile eNB 876452 (40.72265196811989,-74.08804945021805)
    • More confirmations incoming! T-Mobile eNB 880561 (40.74176835140717, -73.88364207139453)   Sprint eNB 6191 / T-Mobile eNB 880065 (40.71339007010928, -73.85695387371624) Confirmed this site but was unable to get a photo because the antennas are set back from the edge of the building. I could see them from super far away but there wasn't a good area for me to pull over and snap a pic.   Sprint eNB 6189 / T-Mobile eNB 877995 (40.71183894845567, -73.83529788316665)   Sprint eNB 253741 / T-Mobile eNB 875537/875538 (40.70170960850086,-73.83302208208359)   Sprint eNB 79912 / T-Mobile eNB 875989 (40.86349197342981, -73.923456682535) — — — — — T-Mobile eNB 880536 in the Bronx isn't a Sprint conversion but rather, T-Mobile changed the eNB when they upgraded the site. The nearest Sprint site at 40.8150405321864, -73.93010756429787 still has all of its antennas up and is literally within spitting distance of two other T-Mobile sites in an area that's very industrial as opposed to residential or commercial so a keep site isn't particularly necessary. You can see on Cellmapper that the old eNB stopped broadcasting about two days after the new eNB went live.  — — — — — Also wanted to add that I spotted AT&T C-band antennas quite a bit in both Queens and the Bronx. I would expect a summer C-band launch announcement from them because they're moving FAST. At least in my area, it seem like they're upgrading at a faster pace than Verizon is. Some more pics: AT&T eNB 116408 / T-Mobile eNB 42887 in Woodhaven. This one is interesting because T-Mobile upgraded this site but in the process didn't put any Ericsson n41 antennas. There are just two of the RFS antennas that we normally get.   AT&T eNB 112047, bad pic but the arrows on the billboard are pointing right at the C-band antenna lol   — — — — — Last edit I promise: I noticed T-Mobile submit a permit to convert the keep site I found in Staten Island (Sprint eNB 75141). I 100% guessed it's location since I connected to it literally 4.5 miles across the water while inside a building. Glad to see I was right!
    • Support for the -1 TAC is good to go now, so I'm ready whenever you are!
