Confirmed data build prop tweaks - T-Mobile, Samsung Galaxy SIII

Ok I spent about week researching these data build props an here are the ones that work an ones that are busted. The main goal was to lock 4G HSPAP 15 an utilize HASP 11 as least as possible which it does I average on my graph 4G 95% (use to be 33%) an 3.5G 5% (use to be 67%). It also allows data rate increase but actual speeds depend on tower congestion but on uncontested towers ur speeds will increase past what it use to be on an uncontested tower an u will get a slight increase on a congested tower than what it use to be. The mod works best on wcdma if u use gsm an wcdma it switches more speraticly causing high latency (ping) an varying speeds from 1.5 mbs to 10 mbs (speeds above are for my area actual varying speeds depend on location)
Hsxpa class 1-5 confirmed 5 being the best since it utilizes all 5 of T-Mobile's frequencies on the fly
Build prop- ro.ril.hsxpa=5
Gprs class an new egprs class
Gprs 1-12 confirmed 10 being just as good as 12 meaning no difference phone utilizes the best multislot configuration on the fly so 12 just gives u more mutislots but the phone descides if its beneficial or not an adjust accordingly
Build prop- ro.ril.gprsclass=12
New egprs class
Same as gprs class but with a higher data rate
Build prop- ro.ril.egprsclass=12
HSPA category
1-10 confirmed
11-12 confirmed
13-14 confirmed
15-20 busted T-Mobile doesnt support MIMO only Dual Cell (LTE will support both)
21-24 confirmed
25-36 busted T-mobile doesnt support dual cell+MIMO , triple cell, triple cell+MIMO, quad cell, quad cell+MIMO, hexcell, hexcell+MIMO, octacell and octa cell+MIMO
Build prop- ro.ril.hsdpa.category=24
Hsupa category
1-8 confirmed
9 busted T-mobile does not support dual cell+MIMO
Buildprop- ro.ril.hsupa.category=8

First off, thank you for taking the time and effort to study this one and not just post the mods On that note, though, I think these are pretty generally used already.
I think the biggest argument against this would be that these settings could be biased based on what area you're in and may not be as effective an other part of the US and such.

U are correct the mods are best suited for HSPAP 15 becuase of HSPA category 24 if ur in an edge or HSPA only are it wont utilize category 24 or HUSPA 8 it will only utilize HSPA category 14 and HUSPA category 5 but the HXSPA, egprs gprs are universal HXSPA is the frequencies TMobile uses ex. 1900, 1700, 2100, 900 and 850 mhz but after the LTE roll out 2100, 900 and 850 will be non exsistant becuase the 1700 mhz band will host LTE an the 1900 mhz band will host HSPAP so HXSPA build prop will have to ne re edited to HXSPA 2 an gprs/egprs class will be none existant so u will have to remove those build props since they rely on the 2100, 950 and 850 mhz bands that Tmobile will be getting rid of

[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.

Is it possible Turn off 4G and use 3G?

I think the biggest battery drain for the phone is the 4G radio. Is it possible turns it off and use 3G?
you can't. you either have data on or data off. What drains the battery more is having your phone switch between edge/3g/H/H+ automatically.
Our phones are not like an lte phone. Our 4g is really just souped up 3g so you either get edge our 4g.

When your phone is switching from 3G to H (which you don't see anymore, all you see now is E or 4G) your not switching technologies. Back when you saw 3G vs H it just ment your phone was idle and not transferring data. When H came on, you were doing data.
There is also no difference in switching from HSPA to HSPA+. It is the same data, just one is a little faster.
Now, before T-Mobile launched HSPA, yes, there was Rev99 data which was slow like Edge and your phone only displayed 3G. But that has been gone for a long time.
As far as switching from GSM to UMTS (Edge data to HSPA data) yes, that will cause battery drain if it is continuous. This is because the phone is trying to reestablish a data connection.
In summary, you no longer see 3G on your phone, only 4G which replaces the 3G/H icons. When you are connected to 3G you are NOT switching technologies when you use HSPA data, your just activating data thus you are NOT draining more than normal amounts of battery. When you switch from 2G to 3G you ARE switching technologies so if your continuously bouncing from 2G to 3G that can cause increase in battery drain.

No, everyone is VERY confused with this. They are the same radio. HSPA+ is the data side of 3G. T-Mobile is just calling it 4G because Sprint got away with hit with their WiMax. EVER cell site on T-Mobile's network has HSPA activated. This means there is no longer 3G data.

Again, people do not know true definitions.
HSPA - 3.5G
WiMax - 3.5G
LTE - 3.5G
Ture 4G technologies are:
WiMax 2 and LTE Advanced.
NO CARRIER IN THIS NATION HAS EITHER OF THOSE TECHNOLOGIES ACTIVATED!!!
Sprint turned on WiMax (not 2nd generation) and called it 4G. So why not follow suit do the same thing. It's all marketing.

well, the drain is likely due to dual cell usage. You can disable dual cell which will knock your top speed down to 21 (theoretical) Mbps. So get to service mode select Debug Screen - > Phone Control -> NAS Control -> RRC(HSPA) Control -> Change RRC Revision ->
DL speeds for items listed are as follows:
R99 = 384kbps
Rel 5 = 7.2
Rel 6 = 14.4
Rel 7 = 21
Rel 8 = 42
hope this helps
Couldn't you force your phone on the 850 UMTS frequency? I say this because I thought HSPA /+ran on the 1700 and 2100 bands so theoretically you could actually be on 3G. I know jugs rom allows you to switch the data icons displayed to 3G for UMTS and H/4G for HSPA /+

T-Mobile doesn't use/have 850 range.
Let me see if I can explain this a little better. T-mobile launched their 3G network on a UMTS platform utilizing WCDMA technology. It's like Verizon and Sprints CDMA but with the W which stands for Wideband. CDMA stands for Code Devision Multiple Access. Wideband is what allows T-Mobile to have such high data rates. Standard CDMA has a 2.5MHz bandwidth while WCDMA has a 5MHz bandwidth for each carrier they are utilizing. Currently, most (not all) major cities have dual carrier launched so those sites are actually using 10MHz of bandwidth. This allows for 42Mbps speeds. 21 for each carrier. We are actually starting to deploy 3rd carrier which will allow 1 carrier just for voice so the full 42Mbps is use solely for data. 84 is a COMPLETELY different story and I will not bother with that for now.
Moving on. When T-Mobile built their network they built it with HSPA in mind. You see, HSPA and HSPA+ are add on data technologies that work on a WCDMA network. They are NOT a separate signal to your phone. Following? Hope so! So, with that said, when your device is connected to a 3G cell site, the data available is HSPA+ and the voice is over what you are calling 3G. They are, in fact, the same signal.
HSPA/HSPA+ data is on the same signal as your 3G voice. You are NOT receiving 2 signals. You CANNOT separate them.
Now, on to frequencies. There are 2 modes that you can run WCDMA in, full duplex and half duplex. T-Mobile decided to go with full duplex. I'm assuming (low man on the totem pole here so don't know for sure) this was to have greater data rates. This is why T-Mobile uses 2 frequencies. 1 in 1700 band for transmit, 1 in 2100 band for receive. This is also where T-Mobile differentiates from ATT (and exceeds! ) because ATT went with half duplex and only uses 1 frequency. So, T-Mobile phones have the ability to transmit and receive at the same time while ATT phones do not.
With all of that said, and hopefully understood, you should now know that it DOES NOT MATTER WHAT THE FRIG ICON YOUR PHONE SHOWS!!!!. Sorry, been trying to get that point across. The firggin icon doesn't not mean ****. The fact that you can have a 3G icon and a separate H does not mean ****. If you do have separate 3G and H icons like older T-Mobile phones and you can see it switching that is because while your phone is idle (NO DATA) it will display 3G. While your phone is doing data (ON THE SAME CONNECTION) it will display H. It is a simple indicator to let you know you are using HSPA data.
T-Mobile did away with both icons and replaced them with the 4G icon when they went to the 4G ad campaign. Get it, got it, good!

I don't think your actually disabling the 2nd carrier. I think your just limiting the max data rate your phone will do. As I previously stated, the phone will connect to what the cell site has. You will always be connected to a 10MHz bandwidth if the site is a dual carrier site.

Was trying to give a simplistic explanation. I guess next time I will just link wikipedia.
The whole point of the discussion was that you cannot turn off the HSPA on your phone and use just 3G. I have not messed with the settings you are suggesting and I don't know that I would as inexperienced users can mess their phones up in those menus. I suppose you could force your phone to R99 mode and that might work but forcing to 21Mbps only I still think you will be using both carriers when using data. Will do testing and report back.

NP. shouldn't have fired back that hard. Technically you only get DC if their is enough capacity on the site so its not a given. You & Allgamer are correct there is no "4G" radio its all one radio on the chip, however changing that setting actually should affect the software which i'll give a brief primer on.
R99 = 1 code with a spreading factor of 16 (surprisingly probably the least power efficient of the group)
HSDPA (7.2) = 10 codes with spreading factor of 16 (in our case likely the most efficient power wise)
HSPA (14.4) = 15 codes with spreading factor of 16
HSPA+ (21) = 15 codes with spreading factor of 16 & 64QAM
HSPA+ (42) = HSPA+(21) * 2.
so with the phone not having to decode 64QAM + using less codes the CPU shouldn't have to ramp up as much to process the data.

I totally agree with this. I'm still not convinced, though, that switching form single to dual carrier is doing much as far as battery drainage. It's not like switching modes between GSM and UMTS or LTE and CDMA (Verizon/ATT world) and trying to reestablish on the network. I mean I guess it could cause a little but something is my brain is just saying that the switching isn't doing that much. Now doubling the bandwidth and data rate, yeah, that is definitely increasing battery usage but the switching itself I just don't know.
Honestly I get mixed battery life depending on my daily usage so testing would be hard. That is unless it's huge differences. I set my phone to Revision 8 and see it its huge improvements.
On a side note, and could just be that phone, but 2 of my friends have Thunderbolts and they get like 2-4 hours of battery life. Something WILL have to be done to fix battery life on LTE.
Well, as somebody said i tried the service mode and got too excited and ****up alot of stuff, wiped and installed jug again but looks like the settings got saved . Anyway to reset all the settings there?

Basically i touched alot of stuff. Wow i ****ed up!!!! no signal and nothing is showing, no dbm or carrier but when i go to settings/networks it shows up att and tmobile in carriers
It also says RRC: IDLE, BAND 5 in basic info
I messed up with Fake Security something, Antenna/adc, network control
Edit: Putting the sim that came with the phone in, it connected and showed dbm but then after 1min it just had an x on the network bars.

I feel like mine said band 4 earlier today but I cant be for sure. I don't have 3G at my house so I can't test till tomorrow.
You could always try reflashing the phone with odin and stock to see if that fixes those defaults but I'm not sure where they are written. Definitely not in the ROM. Maybe the bootloader or radio image have this information stored so flashing stock oden .tar may fix it? Sorry, I really don't know and this is EXACTLY why I said people shouldn't be messing with these settings.

well... i guess in this case too much info is a bad thing. My suggestion was to TOUCH ONLY the RRC settings ... anything else is a crapshoot
yes T-MOs 3G/4G is "UMTS Band IV"
and for future note... if you don't know what your doing and your screwing around in service mode... take SCREENSHOTS before you mess with anything. Or have a buddy with a phone that is untouched.

Reverting the setting back doesn't/didn't do anything for me. I had to flash stock odin rom+recovery
I know someone said previously that the "4G" icons don't mean much as it will usually show "E" or "4G". However, my phone showed "3G" the other day while I was at home and I only saw this once. Someone on another board said that means it was picking up 1900mhz WCDMA as supposedly T-Mobile is starting to use HSPA on 1900mhz in certain areas. Is that correct?

[Question] [Tmobile] Manually select 1900Mhz

Hey guys, since T-mobile is rolling out 1900 Mhz, I was wondering if we could use this on our SGS3s.
I've read reports that say 1900Mhz PCS should be 33% faster than the lower powered 1700Mhz AWS. I would love to test this and seeing as I'm in NYC, I *should* get this.
33% increase source
I did this to test.
*#197328640*#
UMTS->Debug->Phone Control->Network Control->Band Selection->WCDMA Band Preference->1900
Which dropped phone signal, and then promptly found signal again.
It did not, however, register onto the network.
I went to Manual network selection and chose T-mobile. Which told me "error registering on network".
Now, I'm wondering if I've missed a step, or I need a 1900Mhz enabled sim, or could Tmo have just not enabled it yet?
Anyone have any experience with this?

Where did you read/hear that the AWS frequency bands operate at lower power? I didn't see anything of the sort at the link you posted, and find it unlikely.
Perhaps there is just no PCS available in your area yet. That is the first thing I would think.

Something about aws vs pcs technologies. Once again I'm not researched on these terms so forgive any mismatched sets.
I think you're probably right about lack of 1900 bands in this area. I took a look at the 1900 band spotting map and realized that ny metro distribution is more sparse than implied.
I thought 1900 came out when hspa+ did

Not sure where you got any of what you said—the article definitely does not say "should" nor does it say anything about "higher power".
It also says T-Mobile's network modernization effort "have shown a" (that's not "should") a 33% increase, not just the move to 1900 MHz. Their modernization effort includes switching to an antenna-integrated radio and a whole host of technical stuff not mentioned in the press release.

The technology is HSPA+. AWS and PCS are the names of frequently-used wireless bands.
Physics would dictate that performance is WORSE on 1900 MHz (PCS) than 1700 MHz (AWS) (generally, lower the frequency, the better—a big reason why Verizon's LTE on 700 MHz rocks so much).

While I'm sure the verbiage I used was not entirely correct, should vs have shown.
Physics does not show lower frequency to carry more information by definition of the word. Implementation certainly can have effects on utilization as well as other factors such as range, but given equal proliferation, a 1900 MHz wave will obviously carry 19/17 more information than a 1700 MHz ( wave.
However knowing some basic light and optics physics, a 700 MHz wave will have a much larger range. Best example being AM vs FM radio.
I did read the power (possibly TX power) of PCS 1900 MHz could be implemented in a higher level than current AWS 1700 MHz, however I now recall it was just a theory that some members at Hofo were kicking around. I didn't source that so I hope readers would not take that slip in verbiage as fact.

The thing with the frequencies is, the lower ones pass through objects and buildings easier. It's not the amount data that can be carried, but the quality of the connection. The higher frequencies get all messed up b buildings and everything else.

True. The basic rule is higher frequencies are an advantage for capacity, and lower frequencies are an advantage for range/penetration. Of course, this assumes all else being equal. There are many things carriers do to optimize bandwidth and range for whatever use plan they may have. These general rules apply whether the technology is GSM, CDMA, UMTS, LTE, or whatever. Also, remember the AWS bands are only 1700Mhz on the uplink; Downlink is 2100Mhz. That may lead to the perception of lower power, since physics would say the PCS bands will penetrate better.

Ah interesting, I somehow thought that the opposite was true.
You're right that band frequency is just layer 1 of the RX/TX system. But still I'm glad we are able to talk about that to build from the base.

Difference between 4G and LTE?

LTE and 4G are the same? because i know that glide doesnt has lte, but when i use the mobile data, i see the 4G icon. i always have that question. thanks
4g is hsdpa+, which is slightly above 3g, but not quite 4g. It still is fast enough

Then , is better than 3.5G ? (here we know that like 3g and 3.5g). Thanks, for your help thats clear me that question (sorry for my english )
It pretty much is 3.5g.
Sent from my SGH-I927 using xda app-developers app
To give you an idea, LTE can "theoretically" max at 300 mbps (mbps = mega bits per second -- most carriers/ISP's provide this), which would translate to 37.5 megabytes/sec. Do you get that now? Very unlikely. Friends who have LTE are only getting around 24 mbps, which is still really fast.
HSPA+, which is what AT&T's "4G" (not 4G LTE -- it's the 3.5G) as well as T-Mobile's has a peak of about 42 mbps -- and I've seen folks here (Houston) get really close to that in speed -- which translates to a little over 5 megabytes/sec.
T-Mo and AT&T are actively working to get more and more LTE towers and service created (they have HSPA+). T-Mo hasn't rolled theirs out at all, except I think for testing in a few select, small markets, if I remember correctly. AT&T has service in LTE already established.
LTE is the way of the future at the moment. Kind of like the HD-DVD vs bluray debacle years ago -- LTE won out over another 4G technology, WiMax, which was on several earlier phones on Sprint. Sprint finally conceded it lost and start building out an LTE network to replace their WiMax one.
Hopefully, that's a NICE BIG chunk of knowledge that you can partially digest.

Ya it's a huge difference, put it like this;
We get 3mbps and LTE gets 30mbps. Of course I am over simplifying things but LTE is about 10X faster then 3G which is what we have.

Depends on where they're deployed, though. At the moment, in my mind, though, HSPA+ is fast enough. LTE is nice and important for future-proofing, but I don't see a need for it for another... probably 3-5 years. Keep in mind, most people's home internet is like 3-12 mbps on average. HSPA+ current results for my city are WELL above this for all providers.
You realize that Cappy Glide can get HSPA+ which goes up to 42mbps -- you could theoretically download at > 5 megabytes/sec under ideal circumstances... I currently pull around 1-2 megabytes/sec... Why would you ever need more on this current gen -- especially with data-capping?
Just saying I have a friend on the same cellular provider as me and he has that new Windows Phone from Nokia on LTE and me with the glide. We did a speed test and I got around 2.5mbps and he got 25.mbps. I agree for everyday stuff 2.5 mbps is enough, but I just have to say I was drooling when I saw the speed he was getting on Rogers which is whoI have.
I have 2 years left on my Contract and I am happy with my Glide but for sure in 2 years I will make sure my next phone is a LTE device. I have a 6Gigs download cap so I am not to worried about caps after all it is a cell phone and 6 gigs should be plenty.
Fair enough -- seems that Rogers is much different as a carrier than the ones here in the US. I've had friends on HSPA+ on T-Mobile at like 30ish mbps and friends on LTE on Verizon at 35 mbps. It wasn't a super big difference. But until you hit double-digits on the speed, I can totally understand the drool you emit and why.
thanks, thats clear e a lot i always think that 4G was behind of lte but better than 3.5G, because my glide is the unique phone that i see with 4G icon (all the phones here only has 3G icon or H+ and the modems wcdma or Hsdpa) i am not in USA or Canada
I wouldnt say that 4G is HSDPA+ ..
Let's get back to begining ...
1. GSM (2G) 9.6 kbps,
2. GPRS (2G) 40 kbps
3. EDGE (2G) 120 kbps
4. WCDMA (3G) = UMTS and HSDPA 14Mbps
5. HSPA and HSUPA (3.5G) = HSPA+ 28Mbps (unreal speeds / market speeds)
6. DC-HSDPA (4G) 42Mbps and up (unreal speeds / market speeds)

That table is misleading. Most cablecos have rolled out DOCSIS3, capable of 50Mbps at the low end, yet you'd be lucky if there's a 20Mbps package available at all. VDSL is a similar story. Realistically, you're gonna see one, maybe two Mbps real-world, even on LTE. When you're talking about actual bandwidth delivered to your device, you won't see ANY improvement upgrading past UMTS. In the US market, all the benefits of the newer technologies are exclusively on the side of the carriers -- you will see nothing.

OK u are the maaan
The Captivate Glide on AT&T in the US is capable of a rated 21Mbps maximum speed...I have one on a NET10/AT&T SIM in Los Angeles and have so far seen up to 11Mbps in speed tests, but it can also be much slower, dependent on the traffic on the network where I happen to be - the phone's indicator nearly always says "4G" even if my download speeds are less than 500k. If you have a Samsung Relay on T-Mobile (the closest phone to the Captivate Glide design-wise) it has a max rated speed of 42Mbps, and the T-Mobile network usually has faster average data speeds regardless, as long as you're on 4G, but their network is smaller. At this point I'm paying $46 a month on NET10/AT&T versus $55 a month on Page Plus for a 3G phone that maxes at 2.5Mbps (usually around 1200k) on Verizon's network, both with 2GB of data (I use WiFi as much as possible). For my needs I'm willing to spend a lot less with a MVNO prepaid network and live with the HSPA+, rather than paying $100 a month and up for LTE on Verizon, AT&T or Sprint - LTE is also a big battery hog. The fact I was able to get a slightly used Glide for around $100 helped as well, rather than paying hundreds more for an LTE phone and/or being locked into an expensive contract.

UUf i would never pay so much ..
I have one contract for 12 months (sim only) so am locked but am paying £15 a month and I have unlimited internet and unlim. SMS , then 600 minutes that my girlfriend uses .. (she never use all 600 minutes .. she is texting more ..)
And I had Giff Gaff previously .. it is based on O2 but it is cheaper and it is sim only . I used to pay £10 a month for unlimited internet unlim. texts and 250 minutes .. BUT they increased package to £12 so I started NOT liking it cos speed is not as fast as on 3 network
So I have decided to go with 3 network (same as my girlfriend) but it is SIM only pay as u go so it is 15 pounds a month no contract am not locked and I have same package as girlfriend but NOT 600 minutes but 300 minutes of call .. and that is way enough for me .. internet and SMS unlimited that is my priority..

Any way to increase LTE Spark signal strength?

Is there anyway to increase the signal strength of the Note 4?
I have to put the phone up in my upstairs window to get the Spark icon to come on. When I do that, it sometimes switches back to 3g.
I know the Galaxy S3 had an external antenna test port near the battery when you removed the back cover. I don't see any similar ports on the Note 4. BTW, I never used the test antenna port on my Galaxy S3 since I heard it could damage the internal antenna.
There seems to be some electical contacts under the cover of the Note 4. Any ideas on what they are?
I contacted Wilson Electronics and a rep there told me that they aren't allowed to boost or amplify the Spark signal. The FCC won't allow it and Sprint in clamping down on this technology because they want to stay ahead of their competitors.
http://www.wilsonelectronics.com/
I remember people using Pringle cans in the old days with their wireless routers.
Is it possible to extend the Note 4 antenna with a wire? I'm just shooting in the dark.
Thanks.

I have an issue where I will be getting LTE when the phone is sleeping and as soon as I wake it, the phone will drop to 3G. As funny as it sounds I used a plastic ruler to wake up the phone so I my hands or arms would not interfere with the signal and it still does it. This must be some kind of software thing because I used Open Signal to monitor the bands and it legitimately connects to LTE while the phone is sleeping and then switches to 3G when it comes out of sleep. So if I am ever downloading big files or uploading files I usually do it overnight where I will not bother the phone.
I get 2 bars LTE at all times and full signal 3G.
Same problem here. Drops to 3g like hot potato...nexus 5 on my other line holds on to lte b41 like it's life depended on it....
I don't have the note 4 currently (Note 2).
However, with LTE or 3G a "corner reflector" works with the Note 2.
Basically, cut out a box so you're left with only 3 "sides" in a corner, and line it with foil. (Trial and error on the size, I think 12" would be overkill but should work, although a smaller one would as well).
Then, you use a block of foam or such to prop the device somewhere within the corner and also "aim" the corner reflector towards a tower. By trial and error, you can find the best position. It's helped if there's a dialing code (like ##DEBUG# on note 2) that lets you monitor signal strength while you move things around. The trial and error can take some effort...
Wikipedia page on corner reflectors
Example of DIY corner reflector instructions for WiFi antennas
Adding the corner reflector makes the omnidirectional antenna act more like a directional antenna.
If you knew exactly where in the Note 4 the antenna(s) are and what frequency(s), you could calculate out the ideal size of the reflector and position for the device inside the reflector, but I found it easy enough to just experimentally move things around with trial and error.
I've got the same issue. What sad is my area is spark enabled so I should be able to connect to Sprint's 800 mhz (or 850 mhz?) lte network or all. Three frequencies and be on spark. But nope, I'm on crappy 3g but my Note 3will connect to lte.
My Note 4 will connect to lte but it won't hold a connection as good as the Note 3.
Thanks for the reflector info. I will attempt this tonight.

Got your MSL? Go into ##DATA# navigate to LTE/Band Priority and set Band 41 as 1. reboot and see if LTE will hold..

I'll give that a shot but I'm not sure it makes sense.

Most people confuse LTE with Spark, two totally different things. I see in your profile you are in NYC where Spark has rolled out. A lot of forums there's talk about the N4 having a problem switching bands, one work around is setting Band 41 to 1....

What I meant was why make the 2.5ghz band the higher priority? Why not make band 26 (800mhz)the higher priority?
Since my issue is indoors and 800mhz penetrates walls better than 2.5ghz, I figure the priority should be band 26, 25 and Last would be 41?

My thought as well, but seems to be the way to make the N4 switch bands like it should. Like I said I'm reading this in other forums so I figured it might help ya out....:good:

Ah ok cool. Thanks. I'll try out both configurations and see how it works out.

Because Band 26 has not rolled out extensively as of yet, Go to antenna search and see what is rolled out in your area.
NEXTEL LICENSE HOLDINGS 4, INC. Towers are generally listed as such (Band 25 and 26) look at the operating frequency 1900 (Band 25) 860 (Band 26) (if live)
Clearwire Spectrum Holdings Iii, Llc Towers or Sprint Spectrum LLP is Band 41, if dual radios exist in your area or if you area is completely converted.
Change Band priorities is an excellent idea, especially if you are in a Spark area.

I'll take a look at antenna search but based on Sprint, my area is Spark enabled, which I thought means all 3 bands are available. Or am I wrong?
Changing band priority does not work..I've tried it..
Check out Signal Check in the play store too, will show you what you are on.... https://play.google.com/store/apps/details?id=com.blueline.signalchecklite&hl=en
The network will ultimately decide where to put your device based on load balancing and bandwidth/airlink saturation. It typically goes B41,B25,B26. All that changing band priorities does is change what your phone scans for first. Once connected, it's up to the network what band you end up on.
I think something is wrong with the note 4. I am in downtown baltimore., which is supposed to have excellent SPARK coverage. I'm sitting here in my apartment and very very rarely the phone does somehow connect to LTE spark. When it is connected I get somewhere between 6mbps - 35mbps and the signal is -90 to -100 which is pretty good for LTE. As I'm flying along enjoying my 3 minutes of LTE spark, my phone just decides that LTE sucks and it should switch to the 3g signal which gives me 0.12 mbps (f***ing sprint). Then no matter what I do, how many times I do ##72786#, how many times I restart my phone, or turn mobile data on/off it still wont get LTE back..until randomly a couple hours later. Is my note 4 retarded?? The reason I don't think it's a signal issue is that I often get > 30mbps when I am connected. This has to be some software issue where the note 4 thinks that the 0.12mbps 3g signal is somehow "Stronger" than a 35mbps LTE signal.

I agree, I'm in Chicago-land and when i get Spark I always get 1 bar and than it switches to 3g

By default the band priority is Band 25 - 1, Band 25 - 2, and Band 41 - 3. So the phone is already set up correctly as far as priority.
Also as has been stated LTE and Spark are not the same thing. They are two seperate bands. By default the phone tries to use Spark. If it can't it then switches to LTE and if it still has issues it switches to 3G..
