eHRPD disabled?

Has anyone else noticed that after the Verizon LTE outage that CDMA-eHRPD has been disabled and that when we're in 3G we're on EvDo Rev. A?
Does anyone have any information as to why eHRPD was disabled?
Perhaps this could be related to the issues with 4G transition and retention people running CM7 are having.

I manually reenabled it, but it still shows Rev. A as well... Not sure why.

eHRPD is still down, I believe when they restored 4G they stated this, and they stated that 4G to 3G transitions would suffer due to it still being down, I still have it manually disabled so I'm just running on Rev. A

I'm wondering if eHRPD was the cause of this whole issue.
I've been scouring the web trying to find an answer as to why the outage happened in the first place and I am coming up with absolutely nothing. I'm curious to see what happened, why, etc.

This is interesting, and I have also noticed that my phone doesn't automatically go to LTE after entering a 4G area. Gotta put it in flight mode and turn that back off.

Anyone in a NON 4G LTE area have eHRPD back yet? I'm still on 3G EvDo rev a, up until the outage I was always on CDMA- eHRPD.
It kinda sucks because my area is supposed to be coming on line with 4G soon and without eHRPD I cannot look forward to seeing that 4G pop up, since as others have mentioned, the handoff without it is so finicky anyway. If I want to check for 4G I have to manually shut off data and then turn it back on.

Theirs no 4G where I Live and Now im on EvDo rev.A

i'm on Rev. A right now in CT...

Okay thanks guys. Just for clarification: Before the outage, like myself, you were all on eHRPD?
Thanks again! It helps knowing what others are experiencing.

I have rev a in western ny but I can still talk and surf simultaneously
Sent from my ADR6400L using XDA Premium App

yeah I can still talk and surf at the same time too. From what I've read that feature is not affected by whether we are on rev a or ehrpd.
The oddest thing for me has been that since the outage and being on rev a, GPS works flawlessly. Used to take me forever to get a lock, now it's just seconds.

Pomona, NY. Was on eHRPD before, on RevA now and can also run a speedtest while using the phone. Although my speed on eHRPD used to be around 2mb down and on RevA I only get 600k down.

Was always on eHRPD before the outage, but now on RevA. I never did the manual switch to RevA when we were all on 1x. Statesboro, GA

No 4G here in PA yet but phone was always on eHRPD. Now it is on EvDO rev A and it still has Internet connectivity while in a phone call.

cool, thanks man

just got off phone with verizon. they had no clue what i was talking about, i was tranffered 3 times and got te response of "We no longer use the eHRPD Network anymore". also im going to be getting a call back, the rep is going to be doing some research and will be calling me back.

3G EHRPD
I too was one eHRPD before the 4G outage, and now all I get is EVDO rev A
it's not your phone the eHRPD network still seems to be disabled and hence the handoff between 3G and 4G is currently fairly bad, I live about 5 miles from LTE so I experience the handoff quite frequently.

Is LTE down in california?

I'm getting NO data right now. Is LTE down? Any why is it that every time LTE is down, I can't get 3G either

LTE outages started in the Northeast yesterday, but seem to have spread nationwide now. This will cause complete outages on LTE devices due to the switching protocols not working properly
http://www.gottabemobile.com/2011/12/07/verizon-suffering-4g-lte-outage/

I'm experiencing the same thing. Maybe they're preparing for the launch of the two new phones?
Anyhow, my coworker's 3G Droid Pro is working fine...

No data at all for me in South Florida. As for the LTE outage also knocking out our 3g... Blame the SIM card. It authenticates over the GSM (LTE) network.

Try calling *611 I just called and they have a message playing acknowledging the outage. (For my area at least)

And just like that, my data came back. But it's only 3G right now.

I love forums. Within minutes I get reassurance it's not just my phone!

Out in New Orleans, LA as well. *611 confirmed they have an outage in my area.

I haven't had any issues yet today in my 180 miles of driving. Then I had 4g disabled.

Mine went out around 12:45pst. I was next to a has store and they confirmed a nationwide data outage.
Strangely however of all the phones in the store, only the Bionic seemed unaffected. It had 4g when nothing else in store had either 3g or 4g. I'm back with 3g now.

Go to Wireless & Network setting > Mobile Networks > System selection > pick CDMA, automatic. Then you will get 3G. It's better than no data at all.

Tried this when I first noticed the outage. Didn't work. I was getting NO data whatsoever. Full bars with nothing beside it. Could only call and SMS.

Data has been working fine for me all day(North Hollywood, CA). If it matters I'm running EP4P ROM/Modems.

data back up here in San Diego, CA

There is a particular protocol, which currently eludes me, that is required on a mixed LTE/CDMA network to control the switching between the two systems. That protocol is there on every part of the network, not just the LTE segments. If there is a problem with that protocol, this phone isn't going to get any data at all...it doesn't matter if there is CDMA available or not.
Voice and text aren't affected because they don't use the data segment and they don't use LTE, so they don't have to worry with that switching protocol.

FYI For everyone, Verizon just announced about 30 mins ago they have the LTE network back up and running.
I can confirm in NYC i can finally connect back on 4G.

N5 chooses hspa+ over LTE ??

This is my first time with LTE phone and it seems like at times I have to go into mobile networks and select 3g then select LTE again for the LTE symbol to pop up? I'm on straight talk and just didn't know if this was normal or if the phone will select hspa signal if its better than the LTE signal ?

i think by default it will when idle fall back to the strongest network cause it saves battery.
but when you need data it will attempt to switch to the fastest available.
cant say for sure but this is what appears to happen on all my phones falls back to 3g and when data is needed it shifts to HSPA+

I'm getting the same behavior on T-Mobile. My Nexus 4, which was never intended to have its LTE radio used, would stay on LTE, come hell or high water, while I'm in the city and fight to keep it as I left. The Nexus 5 seems picky about it's LTE and only uses it if it deems it good enough. If LTE gets 2 bars or lower, it goes back to HSPA. If you force "LTE only" under the secret dialer menu, it will use its LTE, but when you switch it back to LTE/GSM (PRL), it drops LTE and uses HSPA+. I'm like, "The hell is your problem, your highness?"
I had high hopes driving into work today. I was expecting it to get on LTE much sooner, but it didn't switch until I was deep within the city until I entered the parking structure (which my N4 would still have LTE). While I sit here at work, it refuses to switch to LTE while in the building where my N4, in the same spot, would be happily on LTE.
I just don't get it. I thought LTE would be much better on this device, instead it is worse. I feel like this is a bug of some sort. We are in an age where carriers will begin shutting down their legacy networks (of course, T-Mo is nowhere near as ready), and this phone treats LTE like Sprint WiMax!

Not sure about straight talk but I'm in lte with att if I'm in a lte area.

I suppose I should re-flash my phone then. It's just silly how my phone keeps preferring HSPA+ over LTE. When I had LTE enabled on my Nexus 4, my battery life really didn't change. I suppose it had, but it wasn't perceptible to me.

I've had really good luck with it connecting to an LTE network when inside of a LTE area.
However this morning I was streaming from soundcloud while driving and I was 10 minutes into the city with LTE coverage and it would switch. As soon as I ran speedtest it switched. So I believe what was said up above to be true. It needs a good reason probably too switch if your current network mode is doing fine for your current data needs/battery.
I did read this phone is using Qualcomm s news LTE chip which saves power. That could probably play a role.
Either way I'm totally fine with it because it responded to my need of a lot of data instantly by switching to LTE when I ran speed test.
So hey if it saves me battery and h+ is enough for streaming from soundcloud I'm not going to argue with it.
Hold this helps.

Couple of things to keep in mind.
One, your phone will say 3g when not using LTE or HSPA+. This is to save battery, it only shows LTE or H when you are downloading something, or loading a webpage.
Secondly, I have noticed my phone will choose a strong HSPA+ signal over a weak LTE signal. At home, I have a solid LTE connection, so it always says LTE, but at work it switches back and forth from 1 bar of LTE to full bars of HSPA+. Speed wise, they are still comparable, at around 5-6mb/s. At home though, my LTE is around 40mb/s.
Hope this helps.

So, my Nexus 4 keeping its LTE active all the time except for when making/receiving calls was a "bug" of the hacked radio then? I'm not being sarcastic, I just never owned a true LTE phone before, but my friend who has a Nexus 5 says his LTE has been staying on. It really doesn't make sense for LTE to behave this way as it will replace the legacy networks at some point in the future in which you won't have anything else to fall back to.

Oddly, I haven't noticed this at all. I'm on t-mobile, and my nexus 5 defaults to LTE when I have LTE selected as preferred connection. It doesn't switch to 3g during dormancy as far as I can tell (when I turn the screen back on, its already on LTE).

If you don't mind, would you share how to force LTE only under the secret dialer menu?
Thanks.
[EDIT]
I think I found it with the code *#*#4636*#*# -> phone information -> set preferred network type: LTE only
When I do this and reboot, my bars just disappear, and my APN in my mobile network settings disappears too. I'm using net10.
Anybody know a fix to this?

I don't have to reboot, myself. When I force LTE only, the phone drops HSPA and goes to LTE.
I'd say put it back to GSM/LTE Only (PRL) and then reset your APN settings.

LTE Only Searching For Service Battery?

Hi everyone. Quick question. I searched but didn't find much, but I was wanting to use LTE only (*#*#4636#*#*, Phone, LTE Only), and it does work but on Sprint, it disables 1x and pretends like the phone has no coverage and then does the "Searching for Service" and the battery drains like crazy. Any ideas?

That mode disables all voice and texting abilities, I don't think you can use that on a phone, especially not a phone on Sprint.
turn it back, if the phone doesn't think it has a good enough signal to use LTE, trust it and drop to 3G you'll be better off.

Use global setting for Sprint

I don't want 3g though because my phone has the power to get a signal but if it gets down to 1 bar roughly (driving between towers and I'm in a fairly big city so it's not a coverage/reception issue) and it drops to 3g, despite the fact that it'll get stronger if it waits 5 more seconds.

you can not get/make phonecalls on lte only, period. its for data only.

indeed. setting it through the dialer to lte only, makes that lte data channel the only channel, it kills the ehrpd / 1x cdma 200 ip hand-off needed for voice paging to & from the network..
but NOW i know WHY you were forcing lte only via the dialer (didn't know at 1st)
but where you are (if you're on srpint) this is what' was reported happening -
Sprint used to have "same-as-native" 3G service in the western half of Kansas via those carriers, and even used to show it as Native on their coverage maps. Then it changed to Off-Network roaming a couple years ago. They even stopped Native service along I-70 through most of Kansas and eastern Colorado. Sounds like some of those carriers aren't being too accommodating to Sprint nowadays.

i didn't know, the hometown of sprint, was having such a hard time covering, it's own home state..

That's inaccurate for me as I'm in central KS. That only applies for west KS. I'm in a native market with LTE, NV, and band 25 and 26.

what were your settings prior, to lte only?

Just LTE/CDMA. There are times I want to set LTE only so I don't drop 4g. Of course I have service with that setting.
Sent from my Nexus 5 using xda app-developers app

you know, that going via the keypad to set LTE only you'll kill the fall back bridge to 1xrtt voice & evdo 3g, right?
& every time you want to have voice service you'd have to do the toggle to undo LTE only , then when you want it back LTE only ..
you say "you don't want evdo 3g" but the devil in the details are, you'll not have voice service ither, that way..
is it worth that trouble?

Airave, CDMA and LTE

I just got the Airave and I was wondering how come when I use CDMA only for "mobile networks", I get 5-6 bars i.e. pretty much perfect but when I select CDMA/LTE, I get 1 bar..sometimes two.
More importantly, Airave hasn't fixed this issue but when I go to CDMA only, it seems perfect. How do I go about fixing this?
Thanks
PS - It seems like at home, I have weak LTE (which is what it's connected to by default) rather than holding onto a STRONG 3G signal....how do I make the S5 favor strong 3G over weak LTE?

Which kills more? 3G at -70db or LTE at -102db?

The Airave is only a 3g CDMA over Broadband solution. When you choose CDMA only it's the only choice and is a strong connection. With LTE enabled the device is still trying to keep an LTE link but since your coverage area sucks it keeps falling off. Seems the Sprint GS5 has that issue for everyone where there is bad LTE coverage. It may also be that "Connections Optimizer" crap.
I'd suggest tasker or a similar app for automating setting your mobile network to CDMA Only when at home or elsewhere LTE is crappy and creating another to revert back to LTE/CDMA. There a bunch of threads with people trying to figure out how to optimize their LTE band for their specific coverage. I burned a lot of battery with my N4 constantly trying to decide whether to stick with HSPA+ or other crappy alternative networks. I don't think Google or the manufacturers have done a good job of considering what happens under less than good conditions signal wise.

It's not so much that it falls off but that the signal for LTE is low....around -112db while CDMA/3G is around -70db (full bards).
I wish there was a way to make "CDMA only" turn on at my house while LTE/4G turning on while I leave it....How do I do this using tasker or a similar app?
Then again, I don't really download anything outside of my house....only time I use data outside my house is for Waze or Snapchat or Instagram or Facebook....and they seem to load fine under 3G...it's not worth the battery drain to use 4G for those applications.

The Galaxy S5 only has one radio so this causes huge problems with use of a device like an Airwave. Since Sprint didn't include WiFi calling in the S5 you have no real solution except to force the S5 in to CDMA only mode. It requires a reboot and is annoying. This is ridiculous by Sprint. I went and got a more advanced phone with two radios (The Galaxy S4) and now have no problems with one radio staying attached to 1x Airwave and LTE. I returned my S5 and am now very happy.

With Tasker or similar you'd want to set it up to switch mobile networks to LTE/CDMA based on your location but like rocket said it's a reboot every time - aka PITA. I just set up a shortcut to Mobile Networks and change if it's a problem. Rebooting often sucks. I don't know why they'd give the S4 two radios and the S5 one. Seems stupid. I'm not sure if you can change to CDMA only via the debugging options - that may not require a reboot. There's a big thread about optimizing LTE bands that has a bunch of info on that.

Alrighty. Looks like I'll use CDMA at my house for Airave with Wi-Fi for downloading stuff and have CDMA for downloading stuff while I'm beyond the borders of my house.
I don't "download" anything anyway.

You will be UNABLE TO CONNECT TO THE AIRAVE unless your are in "CDMA ONLY".
Go to
settings/network connections/more networks/mobile networks
and change to CDMA .
( Do NOT select CDMA/LTE until you LEAVE the Airave vicinity)
If you are indeed connected to the Airave, you will hear a recording telling you that you are if you call *99.
You will have to re-enable the CDMA/LTE everytime you leave the vicinity of the Airave to get LTE service.
Sprint Tier II Tech informed be of the above, and I have verified it all by personally testing the above.
Now, here is the real question:
What are the EXACT DIFFERENCES between using the "Wi-Fi Calling Feature" with NO Airave - AND- using the Airave WITHOUT using W-Fi Calling.????

the differnece is the range of the signal / router range of 2.4 ghz/5.0 vs airave 5k to 6k sq ft. and of course haveing a phone made before the s5. any lte+ or sprint spark device will not stay connected to an airave device without network mode selection and crossed fingers. and due to that- wifi calling was born and pushed to the front lines

When you're at home, why not just leave WiFi on for data, and WiFi Calling on for phone calls? That's what I do. I used to use an Airave, but I stopped using my Airave when I got a Galaxy S5 because it has WiFi Calling. (BTW. If you leave WiFi Calling on, your phone will automatically switch to cellular calling when you leave the house.)
