weird 3G behavior


Recommended Posts

I live in Frederick County Maryland my wife's iPhone 5 and my mega if we have LTE turned on oUr 3G speed over the past week have gone into the tank if we turn LTE off and run 3G only there for only using EVDO we get about a megabit which is what we should be getting on 3G I don't know what is wrong with EHRPD in my area but it's been going on for a week Sprint has no idea I'm just curious what is the forums thoughts on what could be going on so I can help possibly troubleshoot a bit

 

*edit* i put Virginia instead of Maryland sorry.

eHRPD is just a software for a seemless handoff from LTE to 3G, essentially eHRPD is EVDO.  You will get the same speeds on 3G EVDO as if you were on eHRPD.  Why would you turn off LTE if it is available in your area?

Same here in MI lately on my Note II.  Data seems to just hang up on EHRPD.  It sometimes unhangs itself but not often.  Works fine on EVDO A (by forcing CDMA mode) or on LTE.

 

Incidentally, to reference a couple of posts up, on the radio level, the difference between EHRPD and EVDO is nothing.  EHRPD sends data through the LTE ground network and DDCs instead of the MSC.  This way, data goes through the same routing for both EVDO and LTE, allowing for better hand off and fewer lost sessions when travelling between them.

If I remember correctly... On the recent root metrics report on network latency it showed both eHRPD and EV-DO performance, and EV-DO had better numbers. Perhaps there is a difference? I've been noticing better performance on EV-DO when my phone drops eEHRPD.

This sounds like a software problem or routing congestion at the DDC. That's my guess.

LTE ISN't available yet only 3g.  all i know is that with ehrpd i get nothing..if i turn off LTE(which kills ehrpd) i get my 3g bandwidth.

The op doesnt have LTE, but to answer your question as to why someone would... i work at the airport in Phoenix.  We have LTE at the Airport occasionally im on the fringe of a couple of towers' range..  i routinely shut off my LTE because ill get stuck connected to one with Signal Check showing 110 or more db so im not getting any data... but connected to LTE so until more towers closer or actually on the airport grounds get LTE when im at work ill routinely shut it off or ill have unusable LTE its pretty but kind of worthless lol

We haven't had eHRPD here in Charlotte for about 2 months now.  Wonder if there is an ongoing issue with it...

I have been seeing a lot of reports of this in the Charlotte thread. Since I have an iPhone, I have no way to tell if I am on eHRPD or EVDO Rev A.

 

I assume I'm not getting eHRPD when I start loading a webpage on 3G and then my phone switches to LTE and all of a sudden my phone says "Could not load webpage because the internet connection was lost" means that it had a hard hand-off to LTE (by being on Rev A rather than eHRPD). Not too big of a deal, considering all I have to do is refresh the page and it loads, but it is odd.

I've only lost eHRPD and been on EVDO once. It didn't seem to cause any negative impact on my data session, but just as quickly as it showed up, it vanished the next day. Not sure what caused the random change, though.

Dumb question. How come Samsung says they need to restart when switching from 3g/4g to 3g only but lg doesn't? My experiences with this are on a S4 and LG Optimus F3.

    • Uploaded data without issues on Friday. Now with the latest update I am getting "Cluster #1 skipped: invalid file format detected. File exported for inspection." Doing same with all other clusters. Did this on 4 phones in a row.  Seems to work on s24 ultra just fine. On s21 ultra it says "web data upload failed. No data to send" although 8800 records were displayed. Now gives same error as above. I have not sent the data from 3 other phones.  All should have latest update.
    • After several months of testing, an update to SignalCheck Pro is rolling out on Google Play. It may take up to 48 hours to become available for download. Notable changes include: Added option to display site notes for NSA 5G-NR cells. Enabling this new option (Preferences > Display Settings > Show NSA 5G-NR Site Notes) will cause the app to make an "educated guess" as to what the most appropriate site note is linked to the connected NSA 5G cell, using the PCI and the device location. If it finds an existing entry that is likely to be relevant, it will display the note along with the distance from where the strongest signal from that cell was logged. While connected to NSA 5G, these notes cannot be edited; a valid NCI is required to add/edit notes and that information is not available on NSA connections.   Added option to log cells with missing/invalid PLMN (such as NSA 5G-NR cells). Users asked for the ability to log data for NSA 5G, so a new option (Preferences > Logger Settings > Log Cells with Missing PLMN) will permit this.   Added option to display LTE info above 5G-NR info. Enabling this new option (Preferences > Display Settings > Show LTE Cells Above 5G-NR Cells) shows the same information that is currently displayed, but moves the LTE information above the 5G-NR information. Other changes: Code optimizations and enhancements. Improved Android 15 compatibility. Overhauled Purchases module. Resolved force closes impacting some GSM/LTE connections. Resolved issue with improper 5G-NR PLMN display when NR/LTE PLMNs did not match. Resolved issue with improper PLMN display with single-digit MNCs. Resolved issue with incorrect 5G-NR bands displayed on some devices due to Android bug. Resolved issue with incorrect number of neighbor cells displayed when some cells were unknown. Resolved issue with missing 5G-NR data when sector display is enabled. Resolved issue with saving 5G-NR site notes when NR/LTE PLMNs did not match. Resolved issue with settings to log missing GCI/NCI/TAC/PLMN being ignored. Resolved issues with web data export function. Updated internal libraries. Updated provider database. Updated target API to Android 15. I appreciate all of your support, and a big thank you to the members of the Beta Crew that help with testing and feedback!
    • Oct security update is out.
    • Stopped by again today and the antennas are up but it isn't live just yet. If other Sprint conversions are anything to go by it'll likely take about a month for the site to go live.
    • It is an Android bug that was reportedly fixed in August 2023 but definitely has not been. I have implemented numerous workarounds in SCP to correct the NR bands the app displays. The OS ignores the possibility that many NR-ARFCNs are valid across multiple bands.. it reports the lowest NR band that is valid for the current ARFCN. In your example, channel 432530 can be n1, n65, or n66.. so the OS just (lazily) reports n1.   Awesome, thanks! I will add an n65 override also.
