Is it possible for vibrant to run on T-Mobile 4G?

After reading of a new Mytouch HD product that is coming for T-Mobile Im pretty impressed with specs but very turned off by the looks.
So that makes me wonder does vibrant have the technology to run on T-mobile's 4G network with simple software updates?
Reason I am asking this is because I know The iphone 4G will be able to run on 4G network as soon as AT&T launch their 4G service.
Thanks for any knowledge in advance

.... Google is your best friend, its not 4g it's hspa+ on order to take advantage of that speed you ned the physical hardware in the phone which only the g2 had right now, in regards to the iphone 4, I've never heard anything about att launching any 4g network, I also work for att, the iphone doesn't have any hardware that support any faster speeds as far as I know

iPhone can handle ATT's new "Faster 3G", but they don't have 4G. My understanding is the Vibrant can do HSPa, but not HSPa+? I don't know the difference but that's what i understand. 2G, 3G and HSPa.

4G is just a marketing terms for the masses. After you look at this link...
http://shop.sprint.com/en/stores/popups/4G_coverage_popup.shtml
You should realize that the Vibrant is already capable of reaching the "average" speeds listed here (in areas with proper coverage). Wait...how is that possible?! It's not a 4G phone. Who cares!!! T-Mobile's network and phones already meet or exceed the speeds Sprint is advertising here. T-Mobile is way ahead of the curve here but they're not marketing the hell out of it. FYI, the average website (ATM) may have trouble maintaining a consistent throughput of 5-6 Mbps anyway. Even if you can go faster, does it really matter when the other side can't (yet)?

T-Mobile does not have a 4G network, and they probably won't roll out 4G for at least 5 years

Apple hasn't announced a 4G Iphone, so (by definition) you really don't know what you're talking about.
AT&T is set to roll out LTE, but it will almost certainly be data-only devices as they work the kinks out. (As Verizon has done)

You should ask yourself why you care about 4G. I doubt you'll notice much of a decrease in load times, and the carriers are probably going to charge out the yin-yang for the enhanced features they will be able to offer to everyone with 4G.
AT&T and Verizon are going to limited data (AT&T already has). You should really look past all the marketing and hype. All the carriers are guilty of confusing the public to serve their interests.

All T-Mobile phones will benefit from HSPA+ as it's backward compatible. However, the theoretical maximum throughput on the Vibrant (or any legacy phone) that doesn't have the HSPA+ antenna built in caps out around 7Mbs as I recall. The G2 which is built to run HSPA+ has a theoretical througput around 15-20 I believe.
Seriously though, even 7Mbs is pretty stupid fast for a cell phone.

Clear explanation
But one thing, i am in Boston and my vibrant never reach over 50KB/s...wtf
It supposed to have the + network already...

I get 6mbps on my vibrant on hspa. Home wifi I get only 2.8, I see no difference in browser page loading time..
Downloading w will be faster but whatever.. 6 is all I need. I've only seen some people getting 8 on their g2s, meh, I'm happy with 6..... Hell I'm happy with 3mbps....

Check the data icon top center - should be two arrows (up/down) and 'G','E', or '3G' to indicate tech. GPRS would be my guess for 50k... EDGE should reach around 200kbps. (I've maxed at about 1.8 mbps 3g in Charlotte, about 210k edge nearer home, and about 12mpbs wifi - same locations as that last my netbook gets 40-70mpbs though.
Check 'settings'->'wireless and network'->'mobile networks' and make sure '2g only' is unchecked. If so I'd suspect a hardware problem. (double-check that 3g is available where you're testing, of course)

This is 3g network already,
My phone and my gf's one has the same result
I can have up to 2000kB/s with my home Wi-Fi....but tmo network sucks..
I never see a "G" in that blue icon
And the above result is based on the 3G icon...if it is E, it has only 4-5 kB/s! !!
Any other guy in Boston can tell me if it is T-Mobile network sucks or my phone

I live in Cambridge and just did the speed-test, 3g w/2 bars in my apartment. 129kbps download 614 upload. It really varies quite a bit probably depending upon network traffic.

theoretical caps. HSDPA 7.2Mbps, T-mobile's variety of HSPA+ 21Mbps according to a T-mobile press release, Wi-fi G 54Mbps.
real word numbers HSDPA 1-5Mbps in good coverage depending on network traffic, HDPA+ on a vibrant 3-7 Mbps again depending on network traffic, Wi-fi... depends on your home internet connection speed.

Some people seem to misunderstand whether or not a non HSPA+ phone (such as ours) can benefit from HSPA+. It indeed can, but not in a straightforward way. In order for T-Mobile to support HSPA+ in a given market they must make reasonable upgrades to their networks backhaul capacity to support it. And these backhaul upgrades will become more important as T-Mobile actually begins selling HSPA+ devices.
One of the most important factors often overlooked with any network is it's backhaul capacity. Bottlenecks in familiar networks can easily make themselves apparent. Take for example the traditional DSL and Cable networks most of us use for wired internet service.
While you may pay for a given advertised speed, whether or not you actually see those speeds has less to do with the connection type and more oftentimes to do with how it has been implemented. In the case of DSL for instance, whether or not you can experience your advertised speed reliably depends on how many other customers are routed through the same DSLAM, *AND* how good the backhaul connection from the DSLAM is to your providers internal network. The same thing occurs with Cable and how many customers are aggregated into a given areas HFC. Bottlenecks within cable and dsl infrastructures occur at different points (because they're architecturally different), but once your outside those infrastructures they both share the potential for having backhaul bottlenecks.
In my area cable is way the fastest connection option, and though I do not pay for the highest speed tier here (15/2, instead of the 10/1 I have), when 10/1 was the fastest tier I'd rarely actually see those speeds. Now I see those speeds reliably. Why? Well there are many factors that effect a network topology, but it's clear that in order to reasonably support 15/2, my cable provider had to make sure it's backhaul could actually handle the load, so it was likely updated to accommodate this.
Hope this clarifies things a bit.

[Q] Will the G2 be compatable with the New Network?

At CES T-mobile announce hspa+21 and 42 mbs speeds upcoming for thier new smartphones. Does anyone know if the G2 will be blessed with these speeds?

From my understanding it should be. Our phone connect to hsdpa+
Sent from my HTC Vision using Tapatalk

I hope so. When I'm connected to WIFI, my speed tests give me 20-22mbs down. On network I get 2-3mbs in my area. I hope there is no limitations or locks to these proposed speeds.

The G2's cellular radio is only capable of 14 Mb/s down.
Sent from my T-Mobile G2 running Cyanogenmod.

The phone only supports up to 14.4 mbps over the cell network (but faster over WiFi). This is a limitation of the Snapdragon platform, and all current Snapdragon phones have this limitation. The next generation 1.2 and 1.5 GHz Snapdragons (no phones with these yet) can handle cell data >14.4mbps.
http://forum.xda-developers.com/showpost.php?p=8324116&postcount=11
If I understand correctly, you will be compatible with the network, but capped by at 14.4 mbps.

The mobile network is limited to 14 mbps down. It won't get any better than that. The phone's hardware is limited to that.

They sure do keep you guessing on what they (Tmo) are gonna do next. No matter, their data network will always suck. They don't even have all their hspa+ network up yet and already talking about another.

their data network will always suck? ha just 2 years ago they were still on edge. i think that going from edge to 3g to 4g in a couple years, is pretty damn impressive. sure its not verizon 3g impressive, but verizon has a hell of a lot more money to throw around because of the sheep that want phones that are so locked down its ridiculous. its almost my fifth year anniversary of customizing my phone now.

We don't really get anything higher then 8mbps, so once they raise the the bar maybe we could hit that 14.4

Note that they are only talking about 21, NOT 42. The place the 42 comes from is what is called "dual carrier".... basically, if you have two phones that are each capable of 21, then add them together and you have 42. Now just take the parts out of the two phones and slap then into a single cover. There you go... a phone capable of 42.
The Vision hardware is definitely only capable of SINGLE CARRIER.... which means that it can't possibly get 42.
Note: I wouldn't completely rule out 21. It *is* amazing what software can do... I also wouldn't *expect* it.
And for that matter, I couldn't care less. 14.4 is very fast. I doubt that there is any actual use in going over that.... mainly just bragging rights.

What are you talking about? HSPA+ 21 is already deployed. HSPA+ 42 is the same concept.
Its all part of LTHE - did you catch the CES demo they ran of the experimental ZTE data stick they were using that was HSPA+ 42? It was pulling 30Mbps down.

Agree... T Mobile data does suck... Theres too many area still on E, or the Slower 3G. Im in a very popular state / city Nashville, TN and we barely have 4G here and the 3G are very slow and unstable, where as the other networks in my area have strong fast connection.
Even Cricket Wireless which to me is a cheap low end cell company has a faster more stable data connection in my area.
This is the Music Capitol of the country and barely got 4G / 3G here LOL...

They need to up it up in houston. It is very spotty. I get 4-5 sometimes but mostly 75% of the time i have 1mb and under. Not cool.

In hawaii I think they only have the hspa tower on honolulu so we all share in one tower, laggy and slow

I agree... they need to work on expanding 3G coverage and phasing out 2G before jumping to beyond HSPA+ 21. More 3G coverage would relieve overcrowded existing 3G towers and therefore increase speed without an upgrade to HSPA+ 42... HSPA+21 is fast enough when towers are equaled out. On a normal 3G tower, I average 7-11Mbps down. Plenty fast, imo.

[Q] Will our N1s be able to run on at&t's new hspa+ network?

Do we have to upgrade our phones to a 4g phone if we want hspa+?
I ask, because t-mobile customers seems to have 4g speeds on their n1s.

No, it doesnt have the necessary radio inside it to do hspa +. T-mobile nexus cant do hspa +. You still might see a speed boost though.

I get 5.2mbps on my Nexus One in Canada. This is still 3G.
T-mobile customers have just experienced a placebo effect (or T-Mobile simutaneously updated both HSPA and HSPA+)

That sounds nice... maybe us att users will at least get a speed boost

You will benefit form HSPA+ on a non HSPA+ device because the backend is upgraded as well.
You're limit is your hardware. The radio on the phone can only get up to 7.2, so you'll benefit from HSPA+ all the way to 7.2.

You hit the nail on the head. With T-Mobile in a very strong HSPA+ area and my N1 is getting DL speeds over 6.5MB, my UL speeds are a very solid 1.5MB. I bought the MyTouch 4G and my speeds are on average 9 to 11 MB on DL and the same UL 1.5MB. I still find myself using my N1, with those DL speeds the N1 is a bad ass phone. Nothing feels as good as the N1 in your hand, maybe it's just me.
PS I still want a Tegra powered device, those phones look hot.

HSPA+ Changes?

Hi Guys I have a question why Does a device that has a 42mbps chip HSPA+ like tmobile galaxy s2 offers you faster speed from the network than the 21mbps device, I mean if you were to make a speedtest in the same location with the same phones and why does the galaxy s2 has like 14~20 Mbps whereas the 21mbps device has 6~10 Mbps, If the device can handle 21Mbps why is it slower?

Yes I did a test in my house on my mytouch 4g slide I got 1-3mbps while my friend got 10mbps+ on his sg2

hspa plus simply means dual connection hspa. It equivalent to having two radios in your phone, ir having two phones, simply put. 2x the connection equals 2x the speed, on networks tha support it. T-Mo doesn't have LTE yet so this is as close as they get, for now.

.
Thread moved. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.

This isn't entirely true. Dual Connection is just one version of HSPA+. So first and foremost the full speed is never available. There are a variety of reasons, the biggest if frequency allocation, for the full speed you need a lot more spectrum. There are also channel effects meaning your surroundings may be adversely affecting your performance. So now comparing two phones one with HSPA and HSPA+, the HSPA+ phone is raw faster because it starts out with much more potential so cutting it by 50% you are still above HSPA.

In any given location, devices with DC-HSPA+ radios will always be around twice as fast as an ordinary HSPA+ radio because the former uses two channels. That's why you see higher speeds on the SGS2 vs. other devices without a DC-HSPA+ radio, unless the SGS2 can only connect on one channel.

Yes I think the new Radio is the difference too, is there anyway to get the DC HSPA+ chip and solder it to the phone's motherboard?, removing the old hspa chip. I see boosts when overclocking to 1.6ghz the Galaxy S 4G from 1.0 like 3~5 Mbps Boost, I think the voltage of the antenna increases thus making further contact with the tower, But at the end of the day LTE is the fastest because is just a different technology, But Tmobile HSPA+ is just way cheaper.

The DC-HSPA+ radio is part of the system-on-a-chip used in the T-Mobile SGS2. There's no way to modify it from a hardware perspective to work on a different device.

What do you prefer and why 4G Late or 42+hspa

Which service is best...

It probably depends on the area. DC-HSPA on T-Mobile actually runs faster than Verizon LTE in some areas just because Verizon doesn't open it up enough or have enough capacity or something. The nice part is that DC-HSPA is really just a fast 3G, so even if your phone only hits 14.4 HSPA, it still goes pretty fast. T-Mobile will deploy LTE next year and if that has problems it will have DC-HSPA as a fallback.

I have T-mobile and I easily get 22mbps down, 2mbps up. My husband has Verizon and he gets 23mbps down, 7mbps up. The downlink speeds are comparable. The only difference is in the uplink speeds. Verizon has the edge here. However, I have used both phones side by side and for most tasks, there isn't a huge difference.

4G Late?
4G LTE
-Destroys Battery life
-Sales Gimmick
4G HSPA+
-Fast enough
-Better battery life

Can anybody really distinguish, with the naked eye, which is faster? Whose testing website is really accurate? Besides bragging rights and marketing fanfare, does it make any difference?

Hi guys,
I do not need LTE due to those facts:
1) HSDPA is fast enough.
2) in common cell phone contracts over here in Germany your speed is reduced to 64kbit after you used up 300mb per month. If I had more than that we could talk about LTE.

FYI there is no "Late 4G", it is called "LTE". Actually there are two types of 4G; LTE and WiMax.
LTE was first used by Verizon, but is now also used by ATT. Due to marketing "schemes" some believe the Apple iPhone 5 has 4g. False! it has HSPA+, not 4G/ Sure, HSPA+ is a ton faster than 3g, but it is still not 4G.
Sprint, and T-Mobile are now also starting to use LTE. Unfortunately I don't believe LTE is standard worldwide, meaning they use different frequency bands. Similar to how a GSM american phone, may or may not work in Europe

I'm sorry that I ever put up such a topic would you ladies and gentlemen please not respond to this stupid topic.I would like to apologize for spamming the thread with this ignorant topic. Takecare

Either way, we won't be hitting 4G for another 5/10 years. Although, I can't imagine why the hell a phone needs 1Gbps down and 100Mbps up. Maybe 30 years from now those speeds will be standard.

LTE and WiMax are still 3G. They're marketed as 4G (read: FauxG). They're really 3.9G.
Only LTE-Advanced is a certified 4G tech. All the others are still 3G

I know that was the case originally, but it's my understanding that the group behind the 4G standards was pushed enough to bend what it qualifies as 4G. Originally 4G was when you had a minimum of 100Mbps download, but now HSPA+, WiMax, and LTE are all considered 4G technologies.

By name only. The carriers cried and whined for it, so the ITU caved. It's STILL "faux G" as far as many people are concerned.
Call it whatever you want. It doesn't change the fact that it's still technically based on an older technology.

Would prefer HSPA than 4G. On 4G, it's really a battery eater. However, the highest HSPA speed I've gotten was around 3mbps and around 1-2mbps upload compared to 30-45mbps download and ~20-30mbps upload.
Normally the HSPA speeds is almost the same as running on GPRS during peak hours until the three local telco was fined for providing below standard data speeds/coverage then it managed to peak around 4-5.

LTE>HSPA+
My best friend bought the black Iphone five (64 gig) when he came down to Jax, and in town, we compared our speed test results.
Iphone five (lte on at&t) first test- 68 mbps down/16 mbps up
Htc Amaze (faux g) best result that day-23mbps down/3 mbps up
So, strictly speed wise, he consistently was able to pull high 60's down, while my phone that theoretically can hit 42 mbps, never reached 30's. So it seems that location is an important factor, but none the less, I cant kid myself, I rooted my phone and changed the values in the build.prop file to command the phone to max out the radio, while his was straight out of the box. Imagine if he were to jailbreak that monster, its capable of 80 mbps down. The only problem is that his screen is smaller than mine, and he has some crappy plan that wont let him tether, as oposed to us, we can hack out phones to utilize our signal on something easier on the eyes.
Now bear in mind, I am just commenting on data speed, and he is back in Greensboro, North Carolina, and he only gets 20mbps down at best. Then again, 20 mbps down would be my phone on a good day in the middle of the night.
