Sensation...less? - G2 and Desire Z Q&A, Help & Troubleshooting

So, PCmag wrote that the Sensation barely meets the "4g" standard.
For those of you getting the phone, will it really matter? it's not like we're hitting high hspa+ speeds anyways.
here's a link. are we allowed to post links? errr.
http://mobile.pcmag.com/device2/art.../www.pcmag.com/article2/0,2817,2386286,00.asp

There really is not speed requirement in the 4G standard anymore. The ITU caved to the carriers and ruled in December that any of the evolved 3G technologies can be considered 4G as long as:
"a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed."
http://en.wikipedia.org/wiki/4G#ITU_Requirements_and_4G_wireless_standards
Pretty much BS, but basically as long as the network is better than 3G, it can be considered 4G. Surprising that supposedly knowledgeable sources like PCMag are getting this wrong. Saying the Sensation is "not 4G" is simply wrong by the current standard.
Also surprising that the Sensation does not support data speeds higher than 14.4 Mbps. I thought this new generation of Snapdragon (dual core, >1GHz) is supposed to support higher download speeds? 14.4 Mbps is the same cap we have on our Visions.

LOL, thanks dude!

Haha... I didn't even know that was an official ruling! Funny. I always thought the 4G marketing from ALL the carriers was hilarious. WE have REAL 4G! No.. WE do..! No.. etc, etc... When I heard that "real" 4G was a theoretical peak of 100 Mbps, I laughed even harder. The way I always "defined" 4G for people is "it's faster than the old network". Who cares if its HSPA+ or LTE or WiMax or UltraHyperYAY! technology, if it's faster than what we had before... well I guess that's 4G. As good an answer as we are likely to get. I'm getting about 7 Mbps since T-Mo "upped" their HSPA+ network, and I can't complain about speeds like that. I don't care if it's 3G, 4G, 5G.... meh. It's fast. I like.

[Q] Question regarding HSPA+ technicality

I'm not versed in spectrum-talk, so here it goes: Why is it that T-Mobile HSPA+ states peak speeds of 21.6 Mbps, yet the G2 states peak speeds of 14.4 Mbps?
Also, what is the difference between HSDPA+ and HSPA+?
The HSPA+ network is capable of 21 Mbps, but the HSPA+ radio chip in the G2 is only rated at 14.4 Mbps. Currently the only device tmobile has that is capable of 21 Mbps is the web connect rocket.
HSPA = High Speed Packet Acces
HSPA includes both
HSDPA = High Speed Downlink Packet Access
and
HSUPA = High Speed Uplink Packet Access
HSPA+ = HSPA of 14.4 Mbps or faster (21 Mbps or the next step is 42 Mbps.

HSPA+(3.75G) is actually newer and faster than HSDPA+(3.5G). In terms of speed, theoretically HSPA+ can reach speeds of 56Mbit/s while HSDPA+ can reach 21Mbit/s. Though in really the fastest your going to get for HSPA+ is 21.6 Mbps. As for why the G2 14.4 Mbps I have no clue. but its faster then my home internet
mtl171,
Technically HSPA+ consists of HSDPA+ and HSUPA+ just like HSPA contains both HSDPA and HSUPA.
I agree that we are unlikely to see HSPA+ networks faster than 21 Mbps in the U.S., I think carriers including T-Mobile will be investing in LTE before 42 Mbps HSPA+ especially since the speed on 21 Mbps is on par with many home broadband connections.
LTE has more benefits for carriers than just speed.

True. though i thought Verizon and AT&T were going for LTE while T-Mobile and Sprint are going with Wi-Max. though i might be mistaken...
Well there are rumors about a merger between Clearwire and T-Mobile.
Anyway, does HSDPA+/HSPA+ rely on MIMO?
Sprint is the only carrier using WiMax
T-Mobile is also going to LTE.
Verizon , ATT, and T-Mobile have all committed to LTE for long term 4G networks.
Sprint is the only one using WiMax, and there is a chance they will switch to LTE also in the long run. Clearwire (which Sprint the majority shareholder) has indicated that their WiMax network could be converted to LTE without much effort.
T-Mobile is deploying HSPA+ currently before deploying LTE.
This makes sense to me, since the speeds of HSPA+ are higher than LTE will be at launch and T-Mobile does not have the network congestion problems that ATT and Verizon have. The biggest advantage of LTE is increased network capacity because of more efficient spectrum usage. I don't think that LTE speeds will pass HSPA+ speeds for at least a couple of years, but LTE has the potential to be faster in the long run.
Verizon is starting to deploy LTE for data cards the end of this year and is rumored to be launching LTE handsets towards the last half of 2011. Depending on the rumors, they may be running behind due to issues with calling over LTE but there are conflicting rumors at this point.
Joebojoe,
HSPA+ running at 42 Mbps and above technology similar to MIMO to download from 2 towers simultaneously.
There are rumors about a Clearwire and T-Mobile partnership. It could make sense for them to partner together for a LTE network roll out, and Clearwire has indicated that it could switch its network over to LTE or run LTE and WiMax.
The other option that has been rumored is that T-Mobile would simply buy some of the excess spectrum that Clearwire has.
Either of those options could make sense, but are just rumors with no real facts to support them. It's fun speculating though.
Thanks for the reply, yet I'm still curious why the G2 is labelled HSPA+ yet only supports 14.4 Mbps. 14.4 Mbps sounds more like HSDPA to me.

idk. design limitations? its still plenty fast. highly doubt people actually get 14.4 Mbps on a HSDPA connection.
Update: its design limitations. According to Qualcomm's website, "MSM7230(proccessor used in G2) support for HSPA+ networks - up to 14 Mbps downloads and 5.76 Mbps uploads"
Like mtl171 posted the 14.4 Mbps speed on the G2 is a limitation of the chipset. I don't think any of the chipsets available for phones HSPA+ at 21 Mbps. The next generation 1.2 and 1.5 Ghz Snapdragon chipsets are supposed to be capable of faster data speeds (if i remember correctly)but they have not reached the market yet.
Joebobjoe,
HSPA and HSPA+ are basically versions of the same technology Hspa+ is the newest iteration. The main difference is the speed.
Please explain... if there are chipsets that support it for the usb dongle, why can't the same thing work on a phone? Have they just not made the chipset small enough for a phone yet?

to tell you the truth, i don't know. but my guess is phones released next year should support it.
Last I heard the 1.2 Ghz Snapdragon chipsets should be released to handset manufacturers late this year or early next year. Then add a couple of months for manufacturers to get handsets built with them, so probably late Q1 for those handsets to get market
rpmccormick,
The chipset in the usb dongle only has to transmit data, it does not have support the other functions of a phone (O.S., wifi, Bluetooth, screen, audio, video, power management, etc..), plus since the usb pulls power from your computer so power management is not as important. The usb dongle uses a much simpler chipset, that only has to transmit data while your computer handles everything else.

Bringing this back since its relavant now....
So just found out about the new Samsung Galaxy S 4g with the new chipsets that give 21+ theroetical speeds....
I am a VERY VERY angry G2 owner who while loves my phone am very upset to find that I will be getting much less speeds out of their network labeled the SAME on both devices. I think this was a VERY deceiving move and hope that with enough complaints we can get some sort of retribution like lower data plan price or what not (the what not are better solutions like a free upgrade but i know those things dont happen as easy)
The only hope is that it can be updated to use 21+ from 14+ but this is HIGHLY unlikely.
Im curious to see what others think of this?
EDIT: this is a smart forum so lets not discuss the fact that not all areas will have that speed and just pretend that im in a market that already is pushing that when using one of those usb sticks..

I wouldn't worry about it too much. If you had a 4G galaxy s side by side with a G2 the galaxy s would very rarely achieve higher speeds. The G2 is a high end android phone that will not be obsolete anytime soon. You could always hold out for the next great phone but no matter what there will always be something better in a few months.
You should be happy about your decision to buy a G2 because its a fast, solid device and still the best phone in Tmo's lineup.

Seriously you are getting that upset? Why do people get so uptight about so many things? Like the previous poster stated, real world is different. But technology moves forward, it doesn't stop for anyone. Life is much more difficult then getting one or two mbps less then another phone. I would be more upset if we never get a gingerbread update (yeah I know I would never use it seeing as I'm a xda member running cm7) simply because of principal. The whole vibrant fiasco would have me really ticked. It wasn't until people really started calling it out and got really loud did things really happen.

HSPA+ in NYC very slow?

I'm seeing very erratic speeds in Manhattan with my new SGS II, but generally I'm in the 2-3 mbps down, 1 mbps up range anywhere I'm inside. Sometimes it is the same outside as well, but occasionally that will spike up to ~16mpbs down outside.
Any other NYC users having similar issues?

Try Sprint 3G/4G or Verizon 3G or AT&T "4G". 100-900Kbps is the norm on Sprint, Verizon and AT&T except AT&T has higher bursts. Verizon LTE is quick but it's already slowed down below 10Mbps here and coverage is not everywhere

Obviously I'm not expecting the 42mbps. But they made a big deal about this being the first DC-HSPA+ phone -- it is, in fact, why this phone doesn't have exynos. Sorry to break it to you, but 2-3 mbps is very slow even for HSPA+ 21mbps. This is slower than Sprint's ****ty wimax.
If you're content with 2-3 mpbs, great, I'm happy for you.

It's not slower than WiMAX here, and if you are seeing a variance in speed it's obvious that you are bouncing between two different cell towers with two different loads or one without Dual Carrier HSPA deployed on it.
2-3Mbps for a network with 1 3G carrier which means all of the bandwidth on that sector is shared with other T-Mobile subscribers is NOT bad. 50-300Kbps/Sprint 3G speed is bad. Verizon 3G at 500-1000Kbps is mediocre but acceptable due to the low ping. 2Mbps is decent, not bad, and OK for a HSPA network.

The 2.5GHz network reaches few people. In a market where Clear actually has people using the network the speeds are much lower due to the traffic. NYC is still very much brand new with few WiMAX users, not a valid comparison. Here, it's 1Mbps all day long due to the maturity of the network and the usage
Unless they're on the same tower as you -- they're going to get different speeds, higher and even lower depending on load. Something you can't comprehend. It's not going to be 10+ everywhere. What are you desperately needing 10Mbps at home for anyway? Do you have an unlimited plan with no throttle cap you desperately want to use? I don't get it.

I've talked to Sprint technicians that are working on the project and they truly believe this will bring them inline with, or better than, the big two.
And that seems very likely.
Lets just hope they keep unlimited data and don't turn into At&t and Verizon.
I've had Sprint for able 6 years, my family has had it for I wanna say 15+, they've had their ups and downs but I believe it's a stable cell phone provider. I can't ever picture myself without it loving my speeds, loving my service (I currently live in the country AND getting 4G) I'll always be a loyal sprint customer and this link you posted makes me happy haha
Anyone have the link to check and see if you have tower updates in your area in the past 6 months or scheduled?
Oh wow...I knew Network Vision was supposed to give them a boost but I didn't think it'd be this much of a boost.

It burns when I tapatalk...
I've learned over the years to believe it when it is done rather than believe the powerpoint.
There are always caveats like, coverage is factoring in 800MHz, but some phones aren't FCC certified to work at 800MHz even though they might be otherwise capable (Photon comes to mind)
Are they running both the 1xAdvanced voice and EVDO carrier at 800 in every market on just the voice carrier or only augmented 800 in select markets? If some markets only get LTE on 800, then that won't help our phones out.
Conceptually Network Vision is the right thing to do, but there can be a significant difference between the design and implementation. The latter is where they usually see the unanticipated issues.
So yeah, it looks good on paper, let's see it in action.

Thank you very much.
Hopefully Sprint does not have too much trouble raising the additional $3 billion needed to complete Network Vision.
I just went on an ADD fueled wikipedia/internet spree because I realized as I was reading that article that I knew nothing about sprints actual network or network at all. I had to keep looking up each term, staring further down Sprint's rabbit hole. I found a lot of interesting information but what really stunned me was that WiMax 4G network runs at 2.5Ghz. By comparison, Verizon's LTE network, which technically by definition is not a true 4G network, runs at 700Mhz.
I cannot wait for this upgrade to come to my area soon enough.
My area:
Past 6 months: 3 data speed upgrades
Planned: 4 data capacity upgrades
Nice!
doesn't Verizon use a 700mhz wavelength for lte which would make better

Rev0 vs RevA is just the air interface. If you connect a fast air connection to a slow backhaul then the lowest common denominator is the backhaul and that will limit your speeds. If there are too many people on the tower sharing the limited bandwidth, that will limit your speeds too.
If you connect a 802.11n wireless router to a 56k modem, what would you expect your Internet speeds to be? That is analogous to what is happening with Sprint, though the backhauls are more capable (and also shared amongst more people)
Assuming you are sure the Verizon connection was Rev 0, it is theoretically capable of 2.45Mbps while Rev A is theoretically capable of 3.1Mbps. Drop around 18-20% for actual use and you get the real-world #s.
So a fast Rev0 could easily beat a rate limited RevA on the download side.
Now the upload side, RevA beats Rev0 by more than an order of magnitude. .15M vs 1.8M theoretical. I'd be surprised if a Rev0 uplink beat a RevA uplink, but if the towers are overloaded enough, anything can happen.

Now the upload side, RevA beats Rev0 by more than an order of magnitude. .15M vs 1.8M theoretical. I'd be surprised if a Rev0 uplink beat a RevA uplink, but if the towers are overloaded enough, anything can happen.

That was just the info i needes. I had also wiki'd it and saw that too. But i like your real world explanation. Yup 2Mb/sec on verizon rev0 and 1.2Mbsec on sprinta revA. Eh o well. Thanks again for getting back to me. Big props to you brother!

I found a lot of interesting information but what really stunned me was that WiMax 4G network runs at 2.5Ghz. By comparison, Verizon's LTE network, which technically by definition is not a true 4G network, runs at 700Mhz.

They have a wider bit of spectrum down there at 700mhz at a much lower wavelength. WiMax and LTE are pretty much just protocols. Verizon's LTE would suck on that thin slice of 2.5gHz and Sprint's WiMax would kick ass at 700mHz....roughly....and that's not taking into considering signal propagation and obstruction penetration.
My 3G speeds suck... but who cares, 4G has gone through the roof down here.
3mb/s -> 9mb/s in my living room
5mb/s -> 18mb/s in my friend's house
I'm gonna go drive all over and run speed tests now.
Orrr... they are showing the map like that because there won't be any buildings in 2013 to penetrate.
Food for thought gentleman.

no 4G?

hi
i recently got a nexus from google.
it woks like a charm but i notice i have never gotten 4G on my phone.
i know there is cus my friend has 4G on his GS2.
so any one knows why is my phone not connecting to 4G network?
any help will be appreciated
PS: the APN i have is epc.tmo.com
HSPA+ (the H icon) is the same thing as T-Mobile's "4G."

its weird, i get a 3G icon then it changes to an H. but when i go to settings i dont have the network mode option to choose from.

It wasn't built to display HSPA+ as 4G for T-Mobile.
Google and rest of Europe considered it plain old 3G.
HSPA+ is not true 4G. It's considered 4G because it's almost as fast as 4G but it's not and people don't mind being tricked by that. They want to feel good about their phone. So they simply accept it.
I would just to brag about it. =p
Look at the AT&T 4S, it has HSPA+ but they don't advertise it as 4G. They just say it's faster then normal 3G.
That's why all my friends on AT&T with a 4S and jailbroken just get winter board and change the 3G to 4G and say they got 4G.
It's as fast so they say, "WTH!!! Let's make people feel like they got 4G and see a symbol that says so, even though they know they don't."
That is why you dont see 4G.
Ahh ok. Im asking cus someone told me i needed a new sim card. But thanks

Yeah I understand why you would be confused. U assume it's 4G since it's as fast. =p
I'd do the same unless I'm told. And since I found out when the 4S came out (I was confused at first), I learned it's just simple 3G on steroids.
Actually one of the firmware updates to the 4S revised the indicator so now it *does* say 4G on AT&T. Which is frustrating because non-technical types now say things like "Well my son didn't get 4G on his Verizon 4G phone in our area, but I get 4G on my AT&T iPhone, so I guess AT&T has better 4G."
I know.
Advertising something that is not true. They can trick people into thinking that the AT&T 4S is better and make people think they have more 4G coverage.
Technically it does since it's considered just as fast. But technically isn't good enough.

The iPhone 4S utilizes HSPA+ just like the Galaxy Nexus. The only difference is that the 4S has an HSPA+ radio that is limited to 14.4Mbps, just like early T-Mobile HSPA+ devices like the G2x. The Nexus has a 21Mbps radio. Functionally, there isn't a whole lot of difference.
Fortunately, we should see true 4G in the states soon, as T-Mobile plans to roll out LTE-Advanced; which, unlike AT&T, Sprint and Verizon's LTE, is the version that actually complies to all of the initial 4G standards, which are not limited to speed. Unfortunately, it will likely still be quite a while before we see speeds of 100Mbps / 1Gbps, which are also one of the requirements. The backhaul and infrastructure for such a network simply aren't utilized in the US. Also, I don't think we really need speeds like that. The initial LTE we have now is still a battery drainer, where HSPA+ still excels in efficiency. The main benefit of LTE and LTE Advanced is changing from a circuit switched network to a fully IP based system, which HSPA+ partially supports.
Correction: The 4S uses HSDPA+HSUPA, which is close but not identical to HSPA+.
HSDPA+HSUPA Release 6
HSPA+ Release 7
LTE Release 8
LTE Advanced Release 10
3G is UMTS. 4G is HSPA/HSPA+
4G and 3G are not the same in these terms.

T-Mobile's HSPA+ is already at 48Mbps in most cases. No word on the max speed for LTE Advanced yet.
Keep in mind that maximum theoretical speed and maximum real usage speed are two different things, but LTE Advanced supposedly reduces a lot of the issues that HSPA+ has, including the speed degradation that HSPA+ has when it comes to distance from the tower and interference.
Also, to be honest, speed tests are just like benchmarks. They really don't show realistic results most of the time. Besides, most of us really only use about 250kbps-3Mbps in actual real time usage, at best and on high load.

They're already on 48mbps HSPA+. When they deploy LTE, it'll be LTE-Advanced, which is the next iteration above the current LTE deployments by AT&T/Verizon.

Verizon's still busy implementing Release 9 LTE. Less incentive for them to upgrade to LTE Advanced, but possible the groundwork has already been laid for it, not entirely certain of what the differences between the hardware needed at the cell site or the hardware needed in the handset have to be.

LTE is quite horrible for battery life. I'm not sure what the difference LTE Advanced will make. I do know that one of the reasons LTE battery life is poor is that LTE coverage is relatively sparse for the time being, as the radio is having to work harder to get and keep a signal than it would if LTE coverage were as prevalent as HSPA+ coverage is.

[Q] Noob: just flashed cm9, no 4g?

Just rooted and flashed cm9 for the first time on my t-mo galaxy sII. Working on restoring apps now through titanium, for what ever reason it is only 3G connection now where it always said 4G previously... any idea why or how to fix?
Two things I noticed. I think the original rom reported 3g as 4g so make sure you actually had 4g originally, but you may want to try another radio. Helped me

As long as you are seeing it switch from 3g to "H", you are getting "4g". CM9's icon is not 4g, it is an h.
Did you try a speed test to see if you are still getting "4g" speeds?
H is 4G on CM9
I've noticed the same thing. Where mine used to say 4G (at work), it now says 3G. However, I'm still getting similar speeds via speedtest so it doesn't really matter what it says to me. However, I still may try a different radio.
Update: I don't know much about it and not sure where the settings are for this, but it appears to be a governing feature with CM9. Meaning that if your phone is just sitting idle it'll catch a 3G signal and when you do a speed test, hop on the browser, download something, etc it then kicks into H/4G.
Just to clarify a lil. Technically tmo doesn't have 4g they have hspa+ 42Mbs.They call it 4g and i have found it offten times to be as fast but it is technically not 4g. CM9 being proper folks and all, call it how it is, hence the H icon.

Sorry man. But your facts are quite out dated. Back in December it was decided that even though hspa +, LTE, and wi Max have not reached the 100 mbs needed to be 4g they are all now officially accepted as 4g.
Funny everyone makes this comment because all T -mobile did was upgrade the existing network .. yet no one mentions the others.. they also do not meet the minimum requirements to be 4G.. well up till December that is..

Well thats good to know, however apparently cyanogen decided to make the distinction between hspa+ and lte, and so i thought I would clarify why there is an H instead of 4G icon.
And upon further research the standard specifies 1 Gbit speeds for pedestrian and stationary devices. Furthermore I dont see any evidence that the definition for the standard was changed simply that the sanctioning body decided to call lte nd wimax 4g because they represented significant improvements on the 3g technologies.
Im in no way knocking tmo for there choice and actually think it makes more sense to fully exploit current technologies rather then investing in new one. An attitude like thats keeps the cost to the consumer lower while still providing a comparable product.

Im sorry I dont see where it is stated that HSPA+ is 4G, In this qoute from the ITU.
Following a detailed evaluation against stringent technical and operational criteria, ITU has determined that “LTE-Advanced” and “WirelessMAN-Advanced” should be accorded the official designation of IMT-Advanced. As the most advanced technologies currently defined for global wireless mobile broadband communications, IMT-Advanced is considered as “4G”, although it is recognized that this term, while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed. The detailed specifications of the IMT-Advanced technologies will be provided in a new ITU-R Recommendation expected in early 2012.
I do see where it call's LTE and WiMax 4G though.

Though is does not particularly say hspa + the network falls under an evolved 3G network.

is rather subjective. But we all get our own opinions. Mine would be that the technology is not particularly evolved, but rather refined allowing greater speed then previous "3G" technology.
In any event I believe we both agree that LTE, WiMax, and HSPA+ are more accurate terms then 4G which is simply used as a marketing tool for people less interested in the matter then most members of the XDA forums.
H means 4g. Who gives a **** if it is really 4g or not. If your phone said 4g with a TMO rom then you will see a H from a Cyanogenmod rom.
