Hi I'm just wondering there's a mode called High speed LTE mode in my setting i'm just wondering is it the same eith VoLTE or not(?) if so can anyone explain to me the difference?

We set out to clarify technical jargons in simple terms so that average smartphone users can make sense of it all, and be well-informed when buying a smart phone and/or a signal booster kit for it. 4G and LTE are closely-related technologies. However, despite what some people think, and despite the impression some networks try to give – they are not one and the same thing. But then what are the differences, and how much do they matter? The first step in answering these questions is to determine what exactly the two terms mean.
What is 4G?
4G is the 4th Generation of mobile internet connectivity, and refers to mobile internet networks that are able to offer certain speeds. These speed criteria were first defined in 2008, long before they were realistic, as something for mobile networks to aspire to, in developing the next generation of internet connectivity.
On-the-go, a network has to offer peak speeds of no less than 100 Mbps to qualify as 4G. In more stable applications, such as stationary hotspots, peak speeds must reach at least 1Gbps. While these speeds may have been nothing more than future targets when they were first set, new technologies have allowed 4G-compliant networks to be rolled out, and some older 3G networks to be improved to offer 4G speeds. However, even so reliably achieving 4G standards proved a bit more difficult than anticipated, and this is where LTE comes in.
What is LTE?
LTE is 4G – in a sense. It stands for Long Term Evolution, and refers not to a single technology but to the processes, developments, and set of technologies used to try to bring about 4G speeds. As it proved more difficult than expected to actually bring about 4G speeds, regulators decided that LTE networks which offered a significant improvement over 3G speeds would be eligible for labelling as 4G even if they did not meet the speeds originally set as 4G standards.
This was a decision companies were quick to take advantage of, and a lot of the time when your phone claims to have 4G reception it is actually connected to an LTE network. This is 4G in a sense thanks to the regulator's decision, but it isn't true 4G in that it does not really meet 4G speed standards. LTE mobile devices are typically capable of CAT4 speeds (Category 4 speeds) and can reach a theoretical speed of 150 Mbps (Mega-Byte Per Second).
What is LTE+ (or LTE Plus) and LTE-A (or LTE Advanced)
LTE+ and LTE-A are exactly the same - The terms are used interchangeably because some carriers in some countries decided to use one or the other for no particular reason. This technology is basically based on the basic LTE platform discussed above, except that the data transfer speeds are triple or even more faster than LTE.
Availability of Plus or Advanced LTE in mobile equipment (smartphones and tablets) is increasing steadily as more manufacturers are manufacturing their flagship or higher end devices that are capable of it (Samsung Galaxy S6 Edge being a prime example). LTE mobile devices are typically capable of CAT6 speeds (Category 6 speeds) and can reach a theoretical speed of 300 Mbps.
The coverage of Advanced or Plus LTE is also gradually increasing as more cellular service providers such as Verizon, T-Mobile, AT&T, Sprint in USA and Bell, Telus, Rogers in Canada are expanding their coverage offering these incredibly high data transfer speeds outside of major cities in USA and Canada, respectively. North American mobile service providers have started this trend of starting with the largest cities first, and then aggressively building their Advanced or Plus LTE networks to support remaining vast areas of their respective coverage areas within their respective countries.
Do the Differences Matter?
In an everyday sense, the differences probably don't matter very much. Most of our signal boosters are also 4G capable (forward to 5G capable and backward to 2G & 3G compatible) whereas all of our commercial boosters are 5G/ 4G LTE compatible. There is not a hugely noticeable gap in speeds between 4G LTE and true 4G networks, and due to time and location variances, these networks will often offer virtually identical speeds. LTE Advanced or LTE Plus on the other hand, offer considerably faster wireless data transfer speeds which may be very helpful if one performs a lot of Internet activities such as frequent downloads, etc. on their mobile devices using their mobile networks. However, it is important to note that in order to take advantage of those higher speeds, the mobile devices have to be capable of those higher speeds and the cellular provider has to have that Advanced or Plus network available in areas of mobile use.
There can be something of a difference when it comes to buying signal boosting equipment. If you are buying a signal booster or repeater with the intention of extending a type of LTE or 4G reception, for example, then you will probably want the one that has "4G" included in its name or description. We sell 4G signal boosters that are compatible with both true 4G, LTE, and LTE Advanced/ Plus networks so you will be covered for all because they are backward compatible, all the way down to 3G and 2G. Now you know the differences between 4G LTE LTE+ and LTE Advanced!

Wow thank you soo much for the information
i canstill achieve speeds of 120mpbs without high speed LTE however

When I bought the phone the day after it came out, I asked the t-mobile guy about 4g and he said that the vibrant is 4g capable so when 4g comes to t-mobile the vibrant will be connected to the 4g network. Is this true?
I'm not so sure... From what I know we don't really...
We will get enhanced speeds, but not the full boost.
But to be honest, it's not something that looks that appealing...
Realistically you will only getting a bout a 15% speed boost, and the coverage will be so limited, so it's no big deal.
The HSPDA network we run on are as fast or faster than anything any other network uses right now. I'm content
G2 is the only phone with "4G" network
ive heard that the hspa+ (4g speed network) will go as far back as the g1. so im sure the vibrant with have it.
and here is a excerpt:
So, how do you get in on the newly-available 4G-ish speeds? If you’ve got one of the handsets pictured above (or the Samsung Vibrant, not pictured), just flip it off and back on — chances are, you’ll see the change right away. Be sure to let us know how the new speeds are down in the comments
from this site, but until its released in a city your in we wont know.
http://www.mobilecrunch.com/2010/07/20/t-mobile-fires-up-4g-speed-hspa-network-in-another-25-cities/
Ok, this is really very simple to explain.
The vibrant supports up to 7.2mbps speeds.
Every T-Mobile 3G-enabled tower establishes an HSDPA connection with this device, with up to 7.2mbps downstream.
3G-enabled towers that are capable of HSPA+ (21mbps) have additional backhaul, which makes it possible to see close to the 7.2mbps speeds.
Towers that haven't been upgraded aren't likely to have a lot of backhaul, so the speeds will be relatively slow, even though the actual HSDPA data session supports up to 7.2mbps.
This is why when an area is upgraded to HSPA+ the vibrant sees better speeds, even though it doesn't support HSPA+. It all has to do with backhaul.
Backhaul = connectivity to facilities equipped with large amounts of Internet bandwidth
Vibrant does not support any kind of actual 4G, but its speeds can be excellent.
3g gets up to 6 down I believe so unless a 3g tower is in your backyard and you are the only person using 3g, you will notice a difference when the flip the switch...
I have upgraded my vibrant plan to 4g and I was wondering if anyone can make a zip for the 4g signal that will match the frobuntu donate theme I asked the developer for frobuntu if he could he hasn't yet so post it on that page if possible I hope he doesn't mind

Vibrant 4g plan?
4g plan?
Vibrant + sXe V3.1 + OCLF
The Web plans were renamed they are still the same at T-Mobile you will only recieve full 4g speeds in 4g areas and on 4g phones.
How do you get a 4g plan on a 3g phone? I did notice in the Flashable Stock JK6 rom sombionix posted has both 3g and 4g icons. I thought you had to have a 4g phone to get 4g service.

I'm thinking the samething. 4g would be based on hardware radio and 4g connection.

You could change the icon to say 10g and you would still never get 4g speeds. Vibrant doesn't support that speed.

Vibrant hardware only supports up to 7mb/s
Fear the beard...
Technicly Speaking Vibrant does support so Called "4G" speed, since its not 4g on Tmobile, 4G its either Wimax (sprint has it) or LTE , T-Mobile has only HSPA+ , so whats HSPA+ its the Same HSDPA network which is Considered to be 3.5G, and since its HSDPA I got speed on Vibrant in Alabama 4.7MBit Per second on speed test, 3G Doesnt support that speed because 3G is UMTS its max 3.6MBit per second, New HTC G2 and HTC Evo 4g or whatever tmobile has at the moment calling "4G" phone doesnt Support LTE or WiMax, it supports HSDPA with 14.4MBit per second speeds, Vibrant works on same Frequency and same HSDPA with 7.2Mbit per second which is Twice less. So Basicly if lets say you live in city where VIbrant can get 3MBit per second , you 4G phone will get 3Mbit as well, but if you live in city where you can get 7Mbits per second on your G2 or 4G phone you will get same speed on Vibrant too. Just icon will not be changed. The trick Tmobile using to let you think you are on 4G instead of 3.5G is by Setting HSDPA network icon as H or 4G instead of regular icon 3G , when phone goes to UMTS it shows 3G, when it goes to GSM it gets to E and so on . So its just Icon nothing more, stop worrying about Icons , what really matters that Tmobile doesnt offer speeds of more than 5Mbit anywhere yet. Maybe maximum 6Mbits if you live close enough to HSDPA Tower. (like 10 feet away). And this speed Vibrant will hold on ease. So Main Point and Bottom Line is ANY Phone that supports HSDPA Network with up to 7.2Mbit per second will be receiving Maximum Tmobile Speed which is avarage 3-5Mbit per second depends on your location and dont mind if it says 3G and not 4G speed on your phone will be Exacly the same since its Same Network HSDPA. Hope it clears everything since its Just Marketing Trick nothing else.
Oh forgot to mention if you have 2 phones in your hand both Vibrant (or any other 3.5g phone) and 4G phone from tmobile , both on same tmobile, sometimes difference can be in speed because it also depends on Antena strenght on your phone, some phones have better antena thats why they get more singnal but difference is not big at all. And if you ll stand next to HSPA+ (HSDPA) Tower with both Phones in your hands , Speed will be IDENTICAL. But on NEW phone it will show 4G even if its on same 3.5G (HSDPA or so Called HSPA+ how tmobile likes to call it) So 4G phone is basicly has overclocked Icon and Vibrant downclocked icon which Displays 3G , I think both phones would be correct if they will show H or 3.5G icon. But if they both will show H or 3.5G who will buy 4g phone ? and why the hell Tmobile then shows comercial of 4g ? Tmobile doesnt want you to know the truth, they want you to believe that by Buying 4G phone (which costs more) you will get better speed which is a big fat lie. Otherwise you will not fall for it and stick with your 7.2MBit/s HSDPA phone and it doesnt matter if its Vibrant or G1 or anyother phone. If you want to check which phones support 7.2MBit on HSDPA or 14.4 and see phones that have Wimax or upcoming LTE check gsmarena.com
these are all 3.5G Phone available for all carriers at the moment notice MyTouch 4G on tmobile in the list ) http://www.gsmarena.com/results.php3?sName=&idMaker=0&chkHSDPA2100=selected&idAvailability=0&YearAnnounced=0&nPriceLow=0&nPriceHigh=0&idCurrency=0&idFormFactor=0&idDualSIM=0&idQwerty=0&HeightMax=0&WidthMax=0&ThicknessMax=0&WeightMax=0&idOS=11&idDisplay=0&idDisplayRes=0&fDisplaySize=0&idDisplayTech=0&idTouchscreen=0&idAccelerometer=0&id35mm=0&idCamera=0&idCameraFlash=0&idVideoRecorder=0&idSecondaryCamera=0&idExpansionCard=0&idGPS=0&bWLAN=0&bEDGE=0&bGPRS=0&idBluetooth=0&bIR=0&bEmail=0&bWAP=0&bJava=0&idRadio=0&bMMS=0&idRingtones=0&sColor=&StandBy=0&TalkTime=0&sFreeText=
Abriviation of HSPA is High Speed Packet Access, Which has 2 types, HSDPA (High Speed "download" Packet Access) and HSUPA (Upload speed)
Niether WiMax nor LTE are 4G, apparently.
They're just faster than what has gone before, but still slower than HSPA+, if memory serves.
Regardless of all that, 'upgrading' your plan to "4G" is stupid with a Vibrant, b/c it doesn't support anything resembling said *G.

the mytouch 4g gets better speeds. Side by side with my friend's mt4g i get 1.5mb max he gets 2.7mb max.
Ok WiMax is slightly Faster than HSDPA for sure (dont mind spint since they USE 3g not WIMAX Network) LTE Can hold Speeds up to 60MBit per second in most countries Minimum speed is 20MBit per second, WiMax can hold up to 20Mbit as well in Most european countries it gets 9-10Mbit Per second. And 3MBit in bad locations. So Officially... 4G its LTE 2 or Wimax 2 which are next generations of Wimax and LTE. But here how it goes, GSM first Geneneration is GPRS, then second Generation is EDGE , then goes UMTS network for phones with Sim Cards, And EDVO-A (same 3g) for CDMA phones. Now Next generation which is 3.5G Its HSPA (HSPA+ its not a special network its still HSPA ) So with Maximum Download Speeds HSDPA 14.4Mbit per second, and upload HSUPA 5.72MBit. Now lets get to 4G , or I preffer to call it PRE-4G But after 3.5G. Main Candidate is LTE! Since I never saw Speed on LTE Network anywhere in europe Less than 14Mbit per second and Maximum speed I saw was 68mbit per second or so with some Europe Mobile Provider. Now lets go to WIMAX. Its not even Mobile network such as GSM or UMTS or HSPA or LTE. Its more of Next generation of WIFI. It works and acts as wifi more than Mobile network but with Big difference. Wifi N Routers for example can work up to 300feet range maybe even little more. While Wimax can work up to like 30-50mile RANGE! So basicly Internet Providers just Use those Special Routers with Huge Antena so you will get signal in your city And trasmit very big download and upload speeds. So thats Wimax. its like Extended range WiFi nothing else. So basicly if Sprint even has WiMax they are acting more like Att or Verizon DSL with speeds up to 3mbit per second plan and just trasmit it over WiMax to you if you are in range ofcourse. If not you will use just EDVO-A (3g)
So Basicly 2g is GSM or CDMA, 3g is UMTS or EDVO-A, 3.5G is HSPA, Pre4G or 4G Candidate is LTE at the moment. And real 4G will be LTE2. Wimax is just Next generation of WiFi.

Well try to run tests like 10 times , and calculate avarage speed. I had problem with my Vibrant that I got 2.8Mbit one time on 1 spot. Its called Latency (lag) then I reran speedtest and it showed 4.5mbit per second. So does it Mean my "3g" phone faster than his 4g ? No since his phone capable of holding 14.4mbit per second on HSDPA while my only 7.2Mbit, But it could mean one of two things, 1 your phone is deffective antena or software for antena or HTC has better Antena and or better Firmware which makes antenna signal is better. Tmobile just doesnt provide good speed in your area. And when you ll run same test on same spot (do not hold sides of your since it can lose signal Antena is on the side of the phone you are blocking it) The proper way to test you and your friends phone is. Put both phones on table make sure distance will be at least few feet from each other so they will not block frequencies of each other. And press SPEEDTEST app same time. And run test about 5-10 times, if your phone will still show slower speed, try to change places put your phone on his place and his on yours. And if still you will get slower speed I suggest you go replace phone since you got it with deffective antena or firmware. But I bet his phone works with Froyo and Vibrant doesnt even have official froyo yet that may fix antena signal. I think vibrant has same problem as Iphone 4 had. But iphone 4 fixed it with 4.1 Firmware which updated baseband and Vibrant didnt have any fix. Anyway I got 4.7Mbit per second driving my car on Highway in Alabama using Stock Android 2.1 JK6. I didnt test speeds in that place anymore sitting on Axura 2.0.6 but in Miami, FL I get mostly 2.5-3.6mbit per second. But im sure if you ll go with your friend to T-Mobile HSPA tower (if you know the location) and put your phones to test you will get same speed. Tmobile doesnt offer bigger speeds than 6mbit Im sure of it. So the phones are equal at the moment.
If you don't like the option for the 4g keep it to yourself but for you idiots I have 4g coverage on my vibrant I upgraded it a few weeks ago and it shows up on my bill as unlimited 4g web so call t-mobile and ask them to upgrade your plan, making statements that you fail to research is ignorant and you just look stupid

NEW YORK (CNNMoney.com) -- You've seen the 4G advertisements from T-Mobile, Sprint and Verizon, bragging about a much-better wireless network with blazing fast speeds.
Here's the secret the carriers don't advertise: 4G is a myth. Like the unicorn, it hasn't been spotted anywhere in the wild just yet -- and won't be any time in the near future.
The International Telecommunication Union, the global wireless standards-setting organization, determined last month that 4G is defined as a network capable of download speeds of 100 megabits per second (Mbps). That's fast enough to download an average high-definition movie in about three minutes.
None of the new networks the carriers are rolling out meet that standard.
Sprint (S, Fortune 500) was the first to launch a network called 4G, going live with it earlier this year. Then, T-Mobile launched its 4G network, claiming to be "America's largest 4G network." Verizon (VZ, Fortune 500) plans to launch its 4G network by the end of the year, which it claims will be the nation's largest and the fastest. AT&T (T, Fortune 500) is expected to unveil its 4G network next year.
Those networks have theoretical speeds of a fifth to a half that of the official 4G standard. The actual speeds the carriers say they'll achieve are just a tenth of "real" 4G.
So why are the carriers calling these networks 4G?
It's mostly a matter of PR, industry experts say. Explaining what the wireless carriers' new networks should be called, and what they'll be capable of, is a confusing mess.
To illustrate: Sprint bought a majority stake in Clearwire (CLWR), which uses a new network technology called WiMAX that's capable of speeds ranging from 3 Mbps to 10 Mbps. That's a different technology from Verizon's new network, based on a standard called Long Term Evolution (LTE), which will average 5 Mbps to 12 Mbps.
Seeing what its competitors were up to, T-Mobile opted to increase the speed capabilities of its existing 3G-HSPA+ network instead of pursuing a new technology. Its expanded network -- now called 4G -- will reach speeds of 5 Mbps to 12 Mbps.
No matter what they're called, all of these upgrades are clear improvements -- and the carriers shelled out billions to make them. Current "3G" networks offer actual speeds that range from between 500 kilobits per second to 1.5 Mbps.
So Sprint and Verizon have new, faster networks that are still technically not 4G, while T-Mobile has an old, though still faster network that is actually based on 3G technology.
Confused yet? That's why they all just opted to call themselves "4G."
The carriers get defensive about the topic.
"It's very misleading to make a decision about what's 4G based on speed alone," said Stephanie Vinge-Walsh, spokeswoman for Sprint Nextel. "It is a challenge we face in an extremely competitive industry."
T-Mobile did not respond to a request for comment.
One network representative, who asked not to be identified, claimed that ITU's 4G line-in-the-sand is being misconstrued. The organization previously approved the use of the term "4G" for Sprint's WiMAX and Verizon's LTE networks, he said -- though not for T-Mobile's HSPA+ network.
ITU's PR department ignored that approval in its recent statement about how future wireless technologies would be measured, the representative said. ITU representatives were not immediately available for comment.
"I'm not getting into a technical debate," said Jeffrey Nelson, spokesman for Verizon Wireless. "Consumers will quickly realize that there's really a difference between the capabilities of various wireless data networks. All '4G' is not the same."
And that's what's so difficult. The term 4G has become meaningless and confusing as hell for wireless customers.
For instance, T-Mobile's 4G network, which is technically 3G, will have speeds that are at least equal to -- and possibly faster -- than Verizon's 4G-LTE network at launch. At the same time, AT&T's 3G network, which is also being scaled up like T-Mobile's, is not being labeled "4G."
That's why some industry experts predict that the term "4G" will soon vanish.
"The labeling of wireless broadband based on technical jargon is likely to fade away in 2011," said Dan Hays, partner at industry consultancy PRTM. "That will be good news for the consumer. Comparing carriers based on their network coverage and speed will give them more facts to make more informed decisions."
Hays expects that independent researchers -- or the Federal Communications Commission -- will step in next year to perform speed and coverage tests.
Meanwhile, don't expect anyone to hold the carriers' feet to the fire.
"Historically, ITU's classification system has not held a great degree of water and has not been used to enforce branding," Hays said. "Everyone started off declaring themselves to be 4G long before the official decision on labeling was made. The ITU was three to four years too late to make an meaningful impact on the industry's use of the term."
I got 4g speed on mine after my upgrade and my signal went from 3g to now says H.

I got my tbolt on launch day, but I don't have lte service in my area so I'm on the ehrpd network 99% of the time.
When I first got the phone I got really impressive ehrpd speeds 2.5 mbps and 1.3 - 1.5 mbps up.
Now after months of lte phones being out I get 1.3 Max and 800 up.
I know that ehrpd is the same as far as maximum speed, but I'm wondering of anyone else has noticed this slowdown in 3g areas, possibly caused by more users on ehrpd

HRPD is implemented in 1xRTT evolved networks such as EV-DO rev.0 and 1 in order to break from a switch based network to a packet based network. EHRPD is supposed to support hand-over from CDMA networks to LTE networks, however, Verizon hasn't widely implemented EHRPD so far as I can tell. I RARELY see a hand-off of an active data session back or forth from CDMA to LTE.
The only things that would really effect your speeds over a CDMA network would be the backing network of the base station (tower) or user base in the cell. I don't believe Verizon throttles that data. They certainly don't throttle data on LTE.

So are you saying EHRPD towers are similar to LTE towers? Or am I way the hell off?

ehrpd resides in the towers with lte and helps with the handoff between going from 4g back to 3g. how many towers currently have it? I do not know, but I'd say not that many.

I'm saying there's not such thing as an EHRPD tower. You've got CDMA towers and you've got LTE. These technologies are VERY different. Let me try to break this down. I probably should have explained it better above.
First, for the record, for cost considerations, LTE and CDMA for Verizon come off the same physical towers. There's not much point in erecting different towers for different antennas if they're still physical space on existing towers.
So... from the beginning...
Verizon runs to completely separate networks today. One is based on CDMA technology, one on LTE. Let me start first with CDMA.
CDMA, otherwise known as Code Division Multiple Access, is a method of physically transmitting a signal to and from a device. Verizon implements asynchronous CDMA to avoid issues with doppler shift in the signal frequency and speed of light delay from transmission to reception. CDMA is the radio access technology, NOT the protocol. The protocol is a patented technology known as cdma2000 and uses the CDMA radio access method as it's base layer.
cdma2000 is the protocol and encompasses a number of transmission protocols. Those would include IS-95, 1xRTT, 1xEV-DO, and the 1xEV-DO revisions 0, A, and B. To clarify, 1xEV-DO stands for single channel evolved-data optimized. EHRPD is a subset data transmission protocol of revision A of 1xEV-DO. I believe that Verizon didn't implement EHRPD very widely in it's deployment of EV-DO rev.A because at the point of first introduction their path of evolution was undecided. They very well could have moved on with EV-DO rev. B and attained speeds comparable to WiMax while being able to upgrade many of the existing CDMA handsets with new firmware to utilize the newer revision, just as had been done when rev. A came. One of the issues with cdma2000 is that the protocols aren't compatible. EV-DO used to stand for Evolution-Data Only, because data is all it does. When the devices is used for a voice call, it must switch protocol modes back to IS-95 to interface with the switch-based voice network on the backside of the tower. This is why CDMA devices cannot do data while in call.
LTE is a completely different technology altogether. It's an evolution of GSM, and accordingly, expands upon the basic technology of GSM. The base of GSM is TDMA, Time Division Multiple Access. Each device has a time slot that it's allowed to transmit or receive data on, usually a small fraction of a second. LTE also makes use of FDMA, Frequency Division Multiple Access, meaning that there are many frequencies that can be used to address different devices.
LTE makes uses of protocols, some similar to GSM protocols, to transmit and receive data. These are described in the LTE specification, and as time passes, additional LTE protocol specifications will be added, such as LTE Advance.
The goal of Verizon is to have a pure LTE network in the future. LTE is not simply a data transmission technology, but rather a full blown cellular standard just as GSM is, and as such can carry voice. When it does, voice will be basically VoIP, as LTE is a completely packet based technology and doesn't depend upon network switching (unlike IS-95 and 1xRTT, which is still the voice carrier technology supported by cdma2000). Carriers like this because it makes upgrading and scaling the network easier. The end result will be a more seamless user experience and the ability to integrate native voice features into data features of the device.
Modern LTE devices accomplish voice and data by using 2 different radios. In the Thunderbolt, that would be the CDMA radio built into the MSM8655 Soc processor and the MDM9600 LTE modem chip. Currently, this is the ONLY combination of chips that allows full simultaneous voice and data over the entire network. Unless the LTE chip of the devices handles both CDMA and LTE, AND can interlink with the SoC radio to manage SAR power limits, this will remain the case. Currently, only Qualcomm chipsets accomplish this, making the Thunderbolt the most functionally connected device ever sold on Verizon.
If anyone is interested in knowing more, let me know. I'll write up a bit more in-depth primer on these subjects and post it.
Thanks
Sorry, I did post this in the wrong forum, and as such I deserve some flaming lol.
I've been around here for a little while since jan 2011, it was just a brainfart.
I know I am connected to ehrpd because under about phone it says cdma - ehrpd
I'm just a little south, maybe 6 miles for the LTE market in Northern NJ, I was just wondering if anyone else in a 3G area experienced a similar slowdown.
I bought a 4G handset knowing it might be awhile before i get LTE, because I was concerned about being stuck in a tiered data plan when I upgraded to 4G, turned out not to be an issue, but I'm still happy I got it, it's a great phone
and I do use LTE occasionally like when to school.
Thanks for all the replies, and if theirs any other oddballs in a 3G area most of the time with a thunderbolt, let me know if you've experienced anything similair

Man that is a mouthful. However, the Thunderbolt can talk & surf the web in 3G mode, not just LTE. So LTE will be a competition for GSM in the coming years?

SO, I have a Samsung Focus and I have a HTC Titan (both AT&T Branded). I also have a AT&T 3g Microcell.
BTW, Has anyone seen an AT&T Titan show 3G at all or anything other than 4G?
Anyways... Here is where the AT&T Titan lies about 4G service.... the 3G Microcell only support a maximum of UMTS. It does not support HSDPA, HSUPA, HSPA, HSPA+, or LTE. Only HSPA+ & LTE are official 4G technologies as classified by the ITU.
On my girlfriends and my phone (when attached to the microcell) it shows 4G (we both have Titans). And Yes, I am positive we are on the microcell since both our phones list AT&T Microcell as the carrier.
I think AT&T is starting to pull one over on people with the Titan. Wish I had a Focus S to verify what it says too....
It has been reported that ATT is branding some H devices as 4G, not even H+... but the Titan is indeed H+. I haven't been very far with my Titan yet, so I wouldn't know if it ever shows 3G.
I may be a bit confused with the network types; to my understanding there is
GSM
Edge
3G
H
H+ (aka '4G')
4G LTE
My HTC Titan has shown E for the Edge network as it has also displayed 4G for HSPA + as well.

I know the Titan does have the HSPA+ capability, that was not my gripe. My grip is that AT&T is listing a true 3G network as 4G which is a bold faced lie altogether and causes us to question if we truely are on 4G or not. Not the fact the device support it or not.
SO, all these throttling threads and stuff about 4G can not use the Titan as a testing source as the tester can not trust if they truely are on 4G or not. Thus skewing true testing results and perceived capabilities.
I live in Las Vegas and AT&T has had HSPA+ for a while and recently LTE. The issue I have, is I can't tell which network I am on wether it be 3G, HSPA+ or LTE since the Titan always will show 4G for all of them.
As added info for you about network types, your 3G disgnation is the same as the network types that I listed. 3G Network types include (In order of evolution):
UMTS - True Desgination for 3G
HSDPA - 3.x
HSUPA - 3.x
HSPA - 3.x
The 3.x is where I am not sure about the history of their release but I know one of them was refered to 3.5g before the true 4g designation came out for HSPA+ & LTE.
I don't think the titan has lte support, so you're definitely not on that.
The best way to go about this I guess is finding the diagnostic menu: where you dial some number and it gives you hidden info and options.

AT&T GoPhone Service here with X310e from Europe, it stay on H all the time, displayed as "3G" sometime.
maybe the way they display the icon on the Europe Phone is different.
Anyone confirm as H is HSPDA+?
BTW, i don't download torrent on my phone either.
Its not exactly a lie. Yes, 4G is now the old 3G. When the other carriers started calling their service 4G, it made AT&Ts service look slower (when reality is that ATT 3G was the fastest).
4G was supposed to be LTE, but the marketing departments screwed that one by trying to one-up each other.
So, the answer is that where you saw 3G previously, you will now see 4G.
I have two microcells and they both show 4G on my Titan as well.
Blame the marketing departments (at all the carriers) for using the 4G moniker where it did not belong.
LTE will hopefully be LTE.
I've seen E, H & 4G on my at&t Titan
You see H? That's a good sign, at least; we can differentiate from E, H and H+. My town is fairly rural and is also a historical district, so I find it extremely suspect that there is 4G wherever I've gone, but I guess we've somehow become modern.
I have also never seen "H", only E and 4G, but I've only been in 3 small towns since I've had my Titan. My "4G" speeds are very 3G-like too... (between 1-2Mbps down and .75Mbps up)
Is there any way to see more detailed radio information in the OS? I dont really trust the indicator at the top of the screen.
As someone quoted the ITU designations. In their final decission it was declared that only technologies being theoretically able to reach speeds of up to 100 Mbps are actually 4G.
This means that WiMax, LTE and HSPA+ don't qualify as 4G. Currently LTE Advanced and WiMax 2 would be the only ones.
The idea of calling HSPA+ 4G as far as I know originates from T-Mobile USA as they are not about to deploy LTE/Wimax anytime soon.
That's even beyond the point. Didn't ATT say HSPA+ users should see actual speeds of around 6Mbps? Many aren't even getting the upper range of "3G" speeds.
I just got off the phone with ATT CS and he did tell me I am NOT in a 4G area, even though my phone is saying so. He told me the nearest 4G area was about 20 minutes south, which is exactly what their data map shows. From that I take that ATT is just calling their 3G network 4G, at least on this phone.

That is false, the ITU adjusted this decision and enveloped HSPA+, Wimax and LTE into the 4G fold.
"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,"

In relation to this post, I have used my Interop Unlocked Focus all around this area and home. On my Focus I enabled the ability for it to show 3G+ areas and I was able to map out areas that were E, G, 3G and 3G+
However, when I trek those same areas with my Titan, I see a somewhat magical "4G" over all 3G and 3G+ areas.
Whether these areas were all H+ capable the whole time is unsure, but somehow I tend to doubt it.
As of yet, I have never seen 3G but I have seen E and G on my Titan.

I just tried that on my Titan by dialing ##3282#, and all the diagnostics are for 3G, HSDPA, no item for HSPDA+, still on screen my phone shows 4G.
arg... is there any way to infiltrate ATT's customer support and actually talk to an engineer, no tricks or PR crap?
I just thought that I'd chime in and say that my HTC Titan shows "3G" when I am at my place of work in Franklin Lakes, NJ.... so it must say 3G for some networks at least.
Do you have an unlocked international phone or an ATT phone?
Is there a Registry Editor for the Titan yet? If so, I wonder if you can change the 4G to what you want it to be like you can on the Samsung Focus? On the Focus, you have the option to change each individual network to show whatever you want it to show.

Using ATT's methods, I've modified my Samsung Focus to receive 6G Speeds. Yes, this is the SAME method ATT uses to get 4G speeds...
They just edit the Registry like I did.
Hi
I was wondering if galaxy i9300 did support some kind of 4g network ?
on the box says it can get 20mbs speed. 3g can't get that speed?
Does anybody know more about this?
i forgot
Im confused about this 3g 4g and lte and blah blah blah
It Supports HSPA+ up to 21mbps. It does not support DC-HSPA or LTE. The i9305 Supports LTE.
The term 4g doesn't really mean much tbh. The technical standard for 4g is 1Gbps which is ridiculous and nothing comes near that.
In the US, they call LTE and WiMAX 4g.
DC-HSPA that three UK are rolling out now is 42mbps which is twice EE's LTE speed
Sent from my GT-I9300 using Tapatalk 4
As stated, i9300 only supports Hspa+ up to 21mbit/second. Some people call this '3.5G' or '3.75G' as it exceeds previous speeds that capped on smartphones that are marketed as 3G (like i9000 which supports only up to 7.2mbps).For comparison, typical LTE speeds are 100mbits/second. There is, however this talk of LTE-A which should be able to break this threshold and get speeds like 500mbits/second
21Mbps is the theoretical maximum for hspa+ ni one will get it, but in strict laboratory conditions it's possible (sat next to the transmitter, ideal conditions and when the planets correctly align.
4g is just 4th generation mobile signals, 1g was the original used in the late 80s designed for calls only, no data, 2g is edge and gprs it can handle data but it's not ideal, 3g is 3g, hsdpa and hspa+ (some refer to the latter as 3.5g) which offers acceptable data speeds, it's the first standard to be designed around data and 4g is LTE and WiMax, WiMax is virtually obsolete already, a lot of US carriers have now moved from WiMax to LTE. 4g offers a theoretical maximum speed of 1Gbps but you will probably get 100Mbps and less.
Also the GT-I9300 does not support 4g, however of you have the GT-I9305 it will support 4g (check model number under about phone)
Sent from my GT-I9300 using Tapatalk 4 Beta just to annoy Gus
I9300 supports HSPA+ sometimes referred to as 3.5G . faster than 3 G on average but slower than LTE some carriers such as t-mobile will call it $G. The ATT motorola atrix in the usa is called atrix 4G . the high end for that phone is about 12 mbits whereas I9300 is 21mbits
