Is it Sprint? Or is it the area vendor? Or someone else? I'm asking because the Charlotte market STILL doesn't have eHRPD and with a good mix of LTE and 3G towers, the handoff issues are extremely annoying.

We did actually have eHRPD for good while, but for the past few months there hasn't been a single lick of it in Charlotte for whatever reason. I too share the frustration that you are having, but you just have to remember, all you need to do is hit "Refresh" when going from LTE to 3G or vice versa and your problem is solved. Patience is a virtue :)

Pretty sure its Ericsson, which handles Sprint's day to day network operations and maintenance. The vendors Lucent and Samsung as well as Ericsson are the companies that are providing the equipment in their respected regions of Sprint's network for Network Vision.

eHRPD isn't the only issue now.  I've lost some 800 towers around here.  They've went back to 1900 only for the time being.  And a strange issue that just started happening is LTE on one side of my apartment building (east side) doesn't work, even though I've got a -96 dbm reading on SignalCheck.  If I got to my apartment, it works just fine (west side).  I have to change to CDMA/EvDo to get my data to work again.  Hopefully they straighten it out soon!

I get a -105 LTE signal in my house, which is unusable, and I go outside and get a -110 LTe form the same Site and it works haha weird

The quality of your signal improved outdoors, yet the "volume" went down.  I can sometimes use a -130dBm signal with really high quality of signal.

It seems odd that Ericsson would be resposible for something in Alcatel Lucent market.

Before Network Vision, Ericsson Network Solutions won a contract to provide all the Network Management for Sprint.  And Clearwire too.  It is a different division of Ericsson than who is deploying Network Vision.  And Ericsson Network division still manages the Sprint network, even on Network Vision sites.  Alcatel Lucent is just a NV OEM.  Ericsson runs the whole Sprint network...at least for now.

If a site goes down or has performance issues its Ericsson's responsibility to get it back up and running, regardless if the equipment is Alcatel Lucent or Samsung's.

And more questions: Is eHRPD implemented at the MSC level, or the tower level? And is there a specific engineer/job position responsible for enabling it? Or is it just any Ericsson engineer that happens to be at the office that day? And is eHRPD at all dependent on legacy equipment? Our legacy vendor is Motorola. Thanks in advance.

I encourage you to read the following which should help you better understand eHRPD.

Speaking of ehrpd does this make sense to anyone?5y6agu3e.jpg

I managed to get it connected once tonight after downgrading firmware on my EVO 4g LTE but after a reboot it won't connect to ehrpd data or LTE. Technically its connected to eHRPD but I don't get any 3g signal. It connected earlier tonight for a few hours after messing with radio modes.

Gprs should say connected. It will only connect to evdo rev a...

I have noticed in the West Michigan Market, Lansing and the surrounding area that I'm only getting EvDo in the last week or so when I drop into 3G areas.  Have been eHPRD for well over a year.

Well, if LTE 800 gets fired up everywhere then eHRPD is not even needed. :)

I thought eHRPD was turned off in markets with eCSFB issues to allow those with N5's, G2's, etc to connect to LTE before the market was 100% complete?

 

At least, this is EXACTLY what happened in Raleigh, down to the day. The day I first got LTE on my N5, was the last day I saw eHRPD in Raleigh.

After a full reboot, my ehrpd is back to normal. Not sure what happened. I had to disable LTE a few times doing speed tests for TRV escalations. Maybe that got it stuck on EvDo.

      My hope is they can spot something in the data that was exported. I am going after all 4 carriers on a multitude of phones and Android versions. My S24 did work.  I have not checked another S24 or S22.  S21s failed which are on Android 14 as well. It should be noted I did not reboot after updates and some of the data was captured on the prior update. Data from some new Boost Mobile Dish (Echostar) sites in the Wheeling area did make it in. Was hoping for more SA data from the duo. Many of the phones are just LTE.

      I was traveling for a couple of days.   Sunday evening, I upload from 3 phones.  A S-22 and two Moto 5G phones.  Everything looked ok.    How do we explain that?   One person has issues and another person does not.  All my phones have the latest update.

      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.

      SignalCheck - Android app to monitor your Wi-Fi/2G/3G/4G LTE/5G-NR signal strengths

      By mikejeep · Posted

      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!
