One easy way is to get https://play.google.....maruse.cellinf (CDMA field test) from the play store and look at the data type on the 3rd line on the right.

 

Another easy way is netmontor https://play.google....zene.netmonitor. (0n the left tab) Both are free.

 

 

eHRPD isn't a good indicator of LTE about to pop in your area. St Louis isn't even on the in coming months list yet and I have had it since I got the Note 2 on launch day. I did have a wohooo! moment when I saw we had it though.

In all seriousness, here is a comprehensive understanding of eHRPD:   For the most part, eHRPD is EVDO-A. Both are 3G CDMA technology. EVDO is a High Rate Packet Data technology, and eHRPD is Evol

Thank you Robert for the detailed technical explanation.

 

<snip>

So, the only difference in performance between eHRPD and EVDO-A on the same site occurs at the MSC vs. the LTE core. Everything else is pretty much identical between the two. Each site in the Sprint network is tied to a very specific MSC for 1x voice and EVDO data. Sprint has dozens of MSC's scattered around the country. When that MSC experiences problems or has a logjam, it affects all the sites connected to it. And EVDO can slow down (although this is not the big culprit in Sprint 3G deterioration).

<snip>

 

Do you know what IS the culprit? I've always thought it's the backhaul. If not, why is 3G so slow? It can't be because Sprint has more customers connected compared to the other carriers...

Mine has always said that too. However, my eHRPD has always seemed to work fine. So I've never thought anything of it.

OK Thanks. I wasn't sure. Everything seems to work fine.

Most likely placeholder naming that was never changed after the fix was put in place. The engineering screens aren't meant for the average user to access. They often have spelling errors as well from my experience over the years.

 

A good example is all Samsung Android devices for a while had an app called "Let's try, panning!" that controlled the motion functionality, I assume, on the devices.

I have noticed ehrpd in knoxville, Sevierville latley. No difference in speeds but 3g speed in this area are pretty good anyway. Knoxville use to not be but about a few months ago it has really sped up. I'm waiting on 4g to just to say I have it but will probably keep it off mostly as i hear it is a battery killer. I have never really had a problem with sprint and I think they are much cheaper than att/verizon and if you get good 3g speeds than it is a better deal. Also I have called sprint a few times or accounts and other thing and i tell you what, They might lie to you but they are always nice in doing so. Always an english speaking rep and extremely nice I guess thats one good thing Dan Hesse did. Anyway I think here in knox we will see 4g lte soon even if its limited at first.

I just rooted my galaxy nexus and installed some ROM called EOS which came with CDMATools. I snooped in there and saw that eHRPD was off. Should I turn this on? My phone connects to lte just fine with it off but maybe there maybe some benefit I don't know about. Looking for anyone who has insight. Thanks.

Yes, my friend with a Galaxy Nexus has a much easier time handing off between eHRPD to LTE than without. CM10.1 had eHRPD disabled by default for a long time up until recently.

May I ask a question?  I looked all over these threads, but could nor find the answer, unless I overlooked something.

 

What frequency is eHRPD on?  Is it 1900 MHz or 800 MHz? 

 

That's all I am receiving with my new Tri Band LG G2 until the fallback issue is rectified.  I'm just curious. 

 

Thanks!

eHRPD runs on PCS/1900Mhz, it is just a software overlay for EvDO Rev A to allow "seamless" communication between CDMA and LTE

If i'm on eHRPD does that mean my area will get LTE in the near future?

 

Before I used to always be on EVDO-A but now usually on eHRPD except some areas. It makes the network usable.

Yes, eHRPD is a good indication that LTE is on the way in the near future.

      Kind of amazing that T-Mobile is still holding onto that speed title despite Verizon all but killing off lowband 5G on their network. While Verizon is mostly being evaluated on mmWave and C-band performance, T-Mobile and AT&T's average 5G speeds include their massive lowband 5G networks that are significantly slower.

      Yup. Very true. We were originally on an Everything Data 1500 Plan, which got Unlimited Minutes thanks to Marcelo's "Loyalty Benefits" offer. We then switched to Unlimited Freedom (with the Free HD add-on that Sprint originally wanted $20/month per line for.... remember that?) because the pricing was better with "iPhone for Life", vs. the "Loyalty Credit" for staying on a Legacy Plan. After that, I ran the numbers and switched us over to Sprint MAX, especially for the international travel benefits. There's absolutely no reason for us to switch to Go5G Plus or Go5G Next if we're going to do BYOD by purchasing from Apple/Samsung/Google directly as we've been doing. These new plans aren't priced for current customers to switch to. They're priced for new customers, where they throw in a free line, etc. It's gone from "Uncarrier" to "Carrier". What a shame.

      Strange business model that they keep around all these pricing plans. 1000s of plans per carrier is reportedly not uncommon.  Training customer support must be a nightmare. Even MVNOs have legacy plans. A downside of their contract mentality I guess. Best to change contracts during a recession. But then all carriers try to squeeze out legacy plan benefits as they grow old.

      Everything "Uncarrier" is becoming "Carrier" again. Because of the Credit Limit that T-Mobile put on our account for no reason at all (and wouldn't change/update the last time I checked all the way up to the CEO), I don't plan on buying/upgrading our iPhones through T-Mobile. I'm going through Apple directly. Looks like I'll be going through Google and Samsung directly for our other lines for upgrades. Also, we're staying on Sprint Max given the ridiculous pricing for Go5G Plus. On Sprint Max, we currently pay for our Plan: $260 for 7 Voice Lines $25 for two Wearable Lines. (One is $10/Month. The other is $15/Month because the AutoPay discount only applies up to 8 lines.) Total: $285/Month vs. Go5G Plus (Per the Broadband Facts "nutrition label" on the T-Mobile Website): https://www.t-mobile.com/commerce/cell-phone-plans $360 - ($5 AutoPay Discount x 7 Voice Lines) = $325 The Watch Plans show as either $12/Month or $15/Month: https://www.t-mobile.com/cell-phone-plans/affordable-data-plans/smartwatches So this is about the same for the wearables as what we're paying now. Overall, it's quite more than we're paying now to switch plans. Ridiculous....
