[Q] HSPA+ and HSPDA Proof.

So here is my question. If you go to Settings > About Phone > Status > and then look under Mobile Network Type, it tells you which type of Network you are currently connected to.
I live in NYC and also in Washington, DC, both arees that should have patches of HSPA+, and I've never once seen my phone connect to anything higher than HSPDA.
My Question is, should it state HSPA+ in my Phone Status screen? And if so, I want proof by way of a screen shot that somebody has actually connected to HSPA+. I've had my G2 since a few days before it was released, and I check this almost everyday to see if my phone will ever display HSPA+ in the Mobile Network Type page in the settings.
Can anybody show me proof that they are on HSPA+? And I don't want to see speedtest results. Everyone claims they are on HSPA+ based on speedtest results. I want a screen shot showing this, IF it in fact does display HSPA+ under these settings when connected.
Sorry if I sound rude, I don't intend this at all, I have been wondering this for months, and have scoured the internet trying to get definitive information on this particular thing, yet to no avail.
I'm very satisfied with my phone, and in fact would recommend it to anyone in the market, I just want to see a screen shot that says HSPA+ in the settings, IF IT EVEN DOES SHOW THIS, that's all!! My phone's network connection is still pretty fast.

Because we all know the "H" could mean a number of things, it doesn't necesarily mean HSPA+ which is why T-Mobile can get away with displaying an "H" for a number of networks (not knocking T-Mobile at all, I'm a loyal subscriber).

If you consider HSPA+ to differ and to be a level above HSDPA or HSUPA, the G2 won't be able to reach it. That's because HSPA+ network can be considered multiple cell HSPA (HSPA = HSDPA & HSUPA) and HSDPA maximum throughput is 14Mb/s. That was the advertised maximum capability of the phone. Most HSPA towers (non-plus) have throughput of 2, 3, 5, 7Mbps anyway, and it's unlikely that the network differentiates between HSPA+ and HSPA. If you find yourself in an HSPA+ cell, your speeds should go as high as 14Mbps, but you may not know if it's HSDPA at it's max or HSPA+ running at a higher speed.

High Speed Packet Access (HSPA) [1] is a amalgamation of two mobile telephony protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), that extends and improves the performance of existing WCDMA protocols. A further standard, Evolved HSPA (also known as HSPA+), was released late in 2008 with subsequent adoption worldwide beginning in 2010... so another words hspa and hspa+ is the same thing.. but when your closer to a "4g " tower of course your internet speeds will respond faster.. to know what kind of internet your on.. go to menu, settings, about phone, than network

It is slow Internet. You don't have a strong signal to 3g, roaming has nothing to do with internet, it has to do with reception...

1xRTT, predecessor to 3g. slower.

I would make sense for it to mean a different band....but I have been seeing this 1x in the CM rom I am running. It happens EVERY time I send a text. It switches from 3g to 1x over the bars.
Yet when the text is sent then I have 3g again and I test it by opening up a browser and watching the data arrows while it still says 3g.
Something odd here.
Q for the OP:....what ROM are u running?

I believe it's cause it's a CDMA phone so the internet sends through the voice line which explains why you can't use 3g during a call.

there is a roaming indicator to notify if roaming. 1x does not 'usually mean youre roaming.'.
CDMA2000 1x is a standard that
aims to bring high data rate capabilities to
wireless communication products. It
supports both voice and 153 Kbps of data
using the same bandwidth configuration as
legacy IS-95A1
CDMA networks (i.e., 1.25
megahertz (MHz) channel bandwidth). This
commonality gives 1x technology
backwards compatibility with IS-95A – the
standards can co-exist in the same system.
When 1x technology is fully implemented,
users will not be required to discard their IS-
95A handsets; however, the additional
capabilities offered by 1x technology will
not operate on IS-95A handsets.

This is the correct answer.
Additionally, any AOSP ROM and a few Sense ROMs (EViO and Mik come to mind) accurately indicate signal strength. This is most often 1x on the Sprint network.
Don't be fooled into believing you once had a stronger signal, you didn't. If you live in the same place you have lived while using the EVO, nothing has changed except the accuracy of your signal indication. Switch back to a typical sense ROM and you'll see 3g all day long.
Also, mms are sent via 1x, while browsing etc is done via 3-4g as available. If nothing has changed but your ROM, you are good.

Is this LTE?

Is this LTE? It still shows 3G in the notification bar but the sidnal doesn't show 1xRtt or EvRev-a insttead its showing and eHRPD ,it is pretty fast compared to what I've been getting her. Also they were where performing upgrades to my towers last week according to customer service.

Yes, it's LTE.
Are you sure you live in an LTE market?
Be mindful the signal strength on this phone is God awful.
However, it is lightning fast once you're on a 4G network.

Not according to the lists but have noticed new style towers and for the last two weeks have had horrid service and now the data is much faster. I will still bounce off a slow tower now and again where I live but this is phenomenal. I live a short distance from a major interstate so I suspect that's why it got updated not on the "cities list".
But why does the notification bar still show 3G?

It still shows 3G because that's what you're using. When you see the LTE logo that's when it'll be active. Sprint is also updating 3G service as well which is supposed to bring faster speeds as well. I suspect that's what you're noticing.

Customer Service
I spoke to customer service last night and brought up the question of the lack of LTE. His answer was that by the end of February or sooner Sprint is dramatically expanding their courage for LTE as well as their two other signals, a total of three signal expands (3G,4G, and LTE) btw LTE is 4 times faster than 4G from what the rep. told me. So lets cross our fingers and hope that by the end of December we get Jelly Bean and by February we get LTE !

Your rep is high on something.
4G IS LTE.
It's just a type of 4G, similar to how WiMax was 4G, and HSPA+ could be considered 4G, but it's really 3.5G.
LTE is just what the interface is called.
I think by the three bands, he's talking about EvDo, CDMA, and LTE

This is what I found from another site...good reading and yes my "3G" speeds have significantly improved since the updated structure.
http://s4gru.com/index.php?/topic/1819-what-is-ehrpd/
"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 Evolved High Rate Packet Data. It is essentially the same exact technology, except eHRPD data is routed through the LTE core instead of the MSC (switch) so it can maintain the same IP address as LTE. This allows for data hand offs between LTE and 3G. Only LTE devices are capable of eHRPD connections.
eHRPD and EVDO-A are broadcast from the same tower on the same channel using the same technology and the same backhaul. It is one signal, not two different signals. However, if your device is in CDMA only mode (or you have a non-LTE device), your data from your device goes from the site through backhaul to a Sprint MSC switching center is processed and dumped out onto the internet backbone.
If your device is in CDMA/LTE mode and your site has been upgraded to eHRPD, when your device data gets to the site, it goes through the backhaul to a 4G LTE core instead of the MSC. There it is processed and dumped out onto the internet backbone.
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).
In contrast to how the MSC's handle 1x and 3G EVDO data, 3G eHRPD and 4G LTE data are processed through 4G cores. Unlike MSC, sites are not limited to only one core. Sprint is setting up their 4G LTE cores to be dynamic. So if one core is too busy, data can be routed to a different under burdened core.
Performance between EVDO-A and eHRPD should be very similar when on the same channel from the same exact site. The most common difference is that eHRPD will often have faster ping times. And a MSC is more likely to bottleneck than an LTE core, so at peak times EVDO may be slightly slower than eHRPD (when all things are the same)."

When you start using the LTE service in your area the icon will change to this......the picture shows my LS970 in Charlotte NC where LTE is just starting up.

Thankyou. By the way did you know there is a section in display settings that you can optimize proportions of indivdual apps so they take up the entire screen? Works great too.

eHRPD is 3G. Its the stop gap between EVDO and LTE. So that the hand off is easier and faster.

[Q] Massive Latency, May be stuck in EHRPD mode. Suggestions?

A few weeks ago I was in an area with LTE. I switched my radio over to LTE/CDMA to take advantage of this. After returning home and switching back over to CDMA, I noticed some issues with my data connection. In regular CDMA mode, my data connection ranges from 1-2 Mbps down and 1--20 Mbps up. My ping is usually 500 to 1000 ms, in CDMA mode or LTE mode. There is no LTE in my area. When it is in CDMA it behaves as if it is in EHRPD. Normally my speeds in CDMA (EVDO REV A) are 1-2 Mbps down and .5-1 up with about 100 ms latency.
I am running stock ROM 4.1.1 rooted with this mod installed: http://forum.xda-developers.com/showthread.php?t=1346680. I have just removed this file with no changes to my data speed. Note that it was working fine before I put it into LTE mode. Any suggestions?

Bump.

eHRPD is simply a bridge between CDMA (or EVDO in this case) and LTE, it allows the passage of network packets between the two networks seamlessly so that it can HAND OFF to LTE in the proper method without losing connectivity or requiring a NEW IP address.
In basic terms... when your phone is connected through eHRPD, it's still using the same existing EVDO network, nothing has changed there, it's just now in a "ready" state for when LTE is "active" on the phone.
So I'm not exactly sure what you mean by "behaves as if it is in eHRPD" because they are essentially the same thing, just operating on a different backbone.
If you're meaning that it's showing eHRPD instead of EVDO now, that is normal, and is most likely because they are planning on implementing LTE in your area soon, maybe not at the specific tower you're connected to, but one or more around that tower. (by soon I mean Sprint's version of the word "soon" which is anytime between now and the next several months)
But that doesn't mean it would affect your speed in any way. (not negatively NOR positively) It's just sending the data packets through a different route, it's still 3G.
Now, aside from that... in my area for example, I'm constantly jumping between 1X and 3G and the call quality is awful, this is because they are upgrading the towers here to LTE, which I confirmed with Sprint in an online chat with their level 2 or whatever Tech Service. So... This could be the source of your problem as well, but you'll need to confirm that with Sprint or check on www.s4gru.com to check their schedule... But I bet it will be worth talking to sprint about it, but you'll need at least an hour or so of free time... they aren't the fastest on checking these things, and sometimes the first person you talk to don't know squat, so you might have to get escalated to someone who can actually look at the real behind the scenes details.

I am familiar with the process that the phone uses for eHRPD. From my understanding, it should not be using eHRPD when it is not in LTE/CDMA mode. My phone was showing these upload speeds when in regular CDMA mode. It was also showing major latency, which is not from a network upgrade. The speeds are normal on my other device and I also checked with a Sprint rep. My device was also having an issue with updating the PRL and Profile. It was giving connection error 6. The rep tried resetting the connection from his end and I tried ##72786# to no avail. In the end, I just backed everything up with Titanium and restored via CWM to a much earlier backup. This fixed the latency, bandwidth and PRL/Profile update issue.

It connects to eHRPD whether its in lte/cdma or just cdma only. If the tower supports eHRPD then it takes priority over EVDO wheter lte is enabled or not. Your latency issues are more than likely due to upgrades in the area. eHRPD handles CDMA 3g more efficiently preventing tower overload, allowing more consistent speeds and better hand off between networks

I was uunclear about H+, have just been looking up info....Was on Verizon, a GSM newbee here
However, I am seeing very slow speeds on HSPA+ and HSP...not even seeing much of a difference in speeds between the two on my device.
between them. Averaging 0.6 Mbps to 1.3 Mbps down, and 0.8 mbps to 1.3 Mbps up, even though T-mobile tech support claims I have excellent 4g coverage in my area. Is this most likely hardware?
Also, on my roadtrip yesterday to Medford, I was capping off at around 10 Mbps on LTE at the most, which seems a ,ittle slow for LTE.

Sometimes your coverage can be solid but the backhaul (connection between towers and the Internet) can be awful. AT&T's local reps even told me that the local LTE isn't going to be particularly good for a while until they upgrade the backhaul to the towers.
Your HSPA+ speeds seem low, but that's in comparison with my AT&T experiences. I might try doing a speedtest comparison of LTE between my Nexus 5 and my Find 7a if I can.

I was reading the pocketnow review and they had trouble getting the phone to work on AT&T and T-mobile in the US. Does this phone even support T-Mobile LTE bands? In most areas T-Mobile has their LTE on the AWS band.

GPRS Setting for LTE works for Me
I was having problems connecting to data,calls no problem (OPPO FIND 7 USA).
Anyway,the automatic APN settings weren't right for me,I had to manually set the APN Protocol setting to IPV4 (wasn't set,reading Not Set) & it finally connected to 4G LTE.
Here's the strange part:
The APN Name (On OPPO FIND 7,USA Model) is T-Mobile GPRS NOT T-Mobile LTE.
If I changed the name,it wouldn't connect to data at all.
From best I can tell via web search, GPRS is synonymous with 2G,however,I have 4G LTE when this APN Name is used.
I've seen others having a hard time connecting to the network & seems this bug arose in the latest update.
Anyway,my settings are identical to those in the pics in the OP EXCEPT the very 1st line,the APN Name.
Where I'm at right now is notorious for a weak signal due to building/equipment interference,however,I'm picking up an excellent signal (-90 to -80dBm / 53asu) on LTE:13

Have you tried to turn on LTE 4G by going in the dialer type *#*#4636#*#* phone information and set preferred network as LTE only ?

Yes.
As it is now,w/the APN Name as T-Mobile GPRS & in the hidden menu,changing the preferred network to LTE has no effect,it stays connected to LTE & everything below that which is available in my area.
I just left it as UNKNOWN.
I tried changing the APN Name to T-Mobile LTE & it immediately disconnects,regardless of any other changes in the hidden menus.
As the phone senses/sets-up Auto APN,the only apparent thing that is omitted is the APN Protocol setting,which by default on my phone & SIM Card registered Not Set.
Changing that value to IPV4 (from Not Set) is what made the difference.
Perhaps this quirk has something to do with 2G in my area having been replaced/upgraded to 4G & 4G LTE & the phone doesn't sense the difference/recognize the difference but in name only,but,accepts the 4G/LTE Connection.
Not knowing all things network/etc..,this seems like a possible explanation.
All I know is that I have an excellent connection & fast speeds w/browsing/etc.....
I don't care what the phone calls it,or sees it as,success is success.
I've seen stranger things than this........

I have since replaced my SIM CARD & had no problems connecting to T-MOBILE's 4G LTE,no modification of the APN was needed.
However,this is while flashed to CYANOGENMOD 11 nightlies,have no idea if the previous issues would pop-up if running the stock COLOR 1.2.4i O/S.

I have had issues with T-mobile LTE. Played around with all the settings. Deleted the APN and created a new one, etc. It works now, but I didn't do anything special, it started working randomly a day or 2 later

Strangely enough I'm having the same problem getting 3g with Virgin (EE/TMobile) in the UK

It can take a while for LTE to provision after setting up the APN. Set it and let it try for about an hour.

APN
The APN setting should have no effect on this.
You have 2 different fields when you type *#*#4636#*#*, gsm service and gprs service. If gsm service does not show "in service", you can use any APN in the world and it still won't work.
