He everyone.
I just read that T-Mobile US now has 4G "HSPA+ Coverage" available in the new G2 being released later this month.
I'm not very knowledgeable in this but I thought it would be super amazing if we could be able to somehow tap into 4G with our Leo/Hd2 through the amazing stuff all you Developers and other do here.
What do you think?
Without 4G hardwrare capable, nobody can do nothing about it, but you can replace 3G icon with 4G, that can fools some.
Yep, it's all in the hardware, so 4G will never happen on the HD2.
T-Mobile is not offering real 4G. So some handsets hat have HSPA already have HSPA+ support. see this link:
http://forums.t-mobile.com/t5/Cover...obile-Now-Broadly-Available-in-the/m-p/378994
But htere is still no list of actual compatible phones.
It is also being discussed in this thread: http://forum.xda-developers.com/showthread.php?t=679752
You have full HSPA (HSDPA and HSUPA) on the HD2:
Up to 7.2 Mbps download speed
Up to 2 Mbps upload speed
You won't get more than that. I don't know about the US but here in France we're just starting to have 3.6 - 7.2 HSDPA bearers activated on some SIM cards and HSUPA 2Mbps is limited also to some expensive plans.
So I'd say the HD2 is still more advanced than the networks it uses here.
If T-MO really has HSPA+, then be happy, at least you're going to have a network that lets you finally use your HD2 to the best of its capacity. And trust me, plain HSPA like what is in the HD2 is already really fast ! Better than DSL broadband in some cases...
edit: the "4G" term as used nowadays is bull**** marketing, as the 2.75G, 3G, 3.5,G, 3G+... this is all to lure ignorant people into thinking you got something better than the competitors and it's just plain ridiculous
Actual testing of your network availability, responsiveness, RTT, throughput: that is the way to go !
Your device is not the bottleneck now, and my guess is it won't be for the next 2 years.
International market is getting Atrix 3G, US is getting 4G. Is there any difference? As far as I know, both versions support HSPA+.

Largely terminology. If you mean HSPA+, then no, there's no difference. Someone has hinted that the Atrix will make it to other carriers. If it goes to Verizon, we could see a version that supports LTE. Then you'll have a difference. Until then, it's HSPA+ on various frequencies (assuming there will be a European version on a quirky frequency, and assuming it hits TMo).

There is no difference at all. In Europe they don't call HSPA+ 4G, so it's not called a 4G phone there.
It's kind of weird, it's probably because of some more restrictive laws outside the US where you can't call a cat a tiger (after all, HSPA+ is NOT 4G). Otherwise, they would surely market it the same way in Canada and Europe.

The idea of US carriers calling HSPA+ 4G is that it is delivering 4G speeds using upgraded 3G technology. 14.4Mbps HSPA+ with AT&T is nearly on par with the LTE speeds we will see on Verizon initially. T-Mobile is cranking their HSPA+ up to 42Mbps or something similar. It will be some time before carriers can really flex LTE muscle, but for now there really won't be that huge of a speed difference, so all these carriers calling their data tech 4G is just marketing.
Besides, LTE is NOT 4G either by definition. LTE is more of a 3.5G technology, similar to HSPA+, but the cool thing with LTE is that over time it can be upgraded to approximately 300Mbps theoretical download speed, while HSPA+ can only be upgraded to approximately 84Mbps download speed.
LTE Advanced will be the first technically compliant 4G technology on the market, but we are still years off from seeing that in the real world.
So take everything you see about 4G as a grain of salt. Atrix 4G vs Atrix is just marketing lingo.
And when people want to say that the Droid Bionic is a real 4G device would technically be incorrect. So don't think your Atrix is in any way inferior to the Bionic (except maybe camera and screen size).

It is now. Standards folks changed their minds, and as of last month or so current WiMax, current LTE, and HSPA+ are all 4G.
when i talked with my rep basically he said they were dropping the 4g just to make things easier. The phone is the same, just some people are still using the superfluous 4g tag.
Does this mean that we can buy a sim-free Atrix 4g from at&t, bring it to europe and use it with european sim cards?or any other gsm sim-cards around the world?

I'd really like to know that as well. Besides this the only thing preventing me from ordering an unlocked version as soon as such is available is the bootloader thing.

same here.thats why im considering galaxy s2 now. i have both moto milestone and galaxy s,the build quality of moto is way better.also my friends like the milestone build and look more,but the locked up bootloader really frustrated me.although there aren't much of great custom roms for galaxy s either,we haven't had a decent cyanogenmod rom around yet, after 8 month since galaxy s been released.
i like atrix more because of better build,higher resolution and tegra 2,but the damn bootloader and later release date along with slightly better specs for s2 like shipping with 2.3 and better camera is changing my desire.
not to mention that this time moto is using PenTile for it LCD and sami is using stripe matrix for its samoled+. thats another let down for atrix.
it was stupid from moto to change the lcd tech on atrix, stripe matrix looked great on milestone.
u can see the differences here:

you can see im pretty confused here!if only the damn nexus s was shipped with a daul core cpu!

Just thought I'd correct you. Tmobile has claimed they can reach speeds of up to 672mbps with their HSPA+ tech. Honestly with speeds like that is there any real need for LTE?
"Now we're seeing a chart of T-Mobile's 4G evolution on the HSPA+ technology path, starting with 21Mbps in 2010. We're seeing 28, 42, 84, 168, and 672Mbps bars here as we move through dual-carrier, MIMO, and so on."

This is basically LTE. They will be switching to it eventually, and these technologies is what makes up most of it.
Just to make sure everyone's aware. Without a huge picocell/femtocell underlay, you will never see anything over 6-12 meg on an LTE network.
The difference between atrix 4g and atrix for europe could be regarding frequencies: 4g shold be 3g on frequencies 850/1900/2100 while european version 850/900/1900/2100. This should be not a problem because almost in all europe 3g works on 2100 Mhz frequency. What do you think about it?

Since most 3G GSM operates in the 2100MHZ area nowadays, I don't this this is too much of a problem (if I'm wrong could someone please correct me?)
I'm now curious as to what exactly is the unlock procedure (sim-wise) of an att Atrix... Can anyone please explain (in detail) ?
The following is an article from Engadget.
http://www.engadget.com/2011/02/23/atandts-brewing-hsupa-gate-the-inside-story/
Though it really came to a head with the recently-launched Inspire 4G, users have noticed that there really aren't many phones in AT&T's stable that deliver stellar upload speeds -- the Atrix 4G is suffering the same sub-megabit performance, as are older devices that should seemingly support HSUPA like the Samsung Captivate.
We've chatted in the past few days with a source who offers an interesting explanation: AT&T currently requires that all handsets that it sells "handshake" with the network as 3GPP Release 5 devices, the last official set of 3G specifications that lacked support for HSUPA. That feature -- also known as EDCH, or FDD Enhanced Uplink -- was added in Release 6. Though AT&T is apparently working on permitting the bulk of its handsets to handshake Release 6, presently only the iPhone 4 (and presumably all of its recent data devices like USB modems, which may also use Release 7) are allowed. Neither we, nor our source, know why this is. Our source believes that the Release 6 certification may happen within a "month or two," which would explain why some AT&T sales reps in live HSPA+ areas are telling customers that the "4G network" isn't live yet.
You can form your own conclusions as to why AT&T might be imposing this arbitrary limitation, but we do know that "enhanced" backhaul figures prominently into the company's 4G story; there may be concerns that flipping on HSUPA for everyone right now would overwhelm its legacy infrastructure. At any rate, it sounds like this could all be solved soon through a combination of network changes and possibly firmware updates for individual devices, so let's keep our fingers crossed.

Here's the reason why it is slow. At least now we know why. And yes I know Engadget is not the best information site, but I have read this on other sites as well.
Hey guys, had a quick question. Since the Atrix is a SIM oriented phone and Verizon is pumping out these LTE sim cards on new phones, shouldn't it be theoretically possible to use Phones like the Atrix on Verizon? Any development with this?
Maybe I am being stupid here and these two technologies are completely different.
idk, i doubt it, but the bionic that's coming out for Verizon is pretty much the atrix with less ram and no laptop dock
Nope. First off, what AT&T is calling 4G currently and what Verizon is selling are completely different technologies. HSPA+ is just normal old AT&T 3G system with an Ethernet backhaul to increase speed a bit. AT&T will also be building an LTE (true 4G) network, but that's not the "4G" these devices are built for.
But to go further. LTE and 3G/HSPA+ sims are completely different things. Top that off with the fact that Verizon will be using dual tech CDMA and LTE phones, while AT&T will be using LTE and HSPA technology. So, even if you did get a Verizon LTE sim for an AT&T device, you would only be able to use the phone in an LTE environment. You're still going to be on the 3G/3.5G network 90% of the time till the infrastructure gets built out. That is, unless the handset is carrier agnostic, like the iPhone 6 is supposed to be. It'll supposedly work on any network.

"Well well well look at what we have found for you folks that are on Sprint. We are not quite certain if this video was posted early or not, as Sprints big network/3G/4G conference is not until next month, but from the look of things their network enhancements are already well underway. What should you expect as a Sprint customer? How about EvDO Rev B which should see speeds in the 5 to 10Mbps down link depending on channel bonding, 1X Advanced which brings voice and data at the same time, as well as spectrum bonding to bring the best coverage available. Even better, Evo 3D and Epic Touch 4G users may be able to take advantage of this very soon.t Lets not forget who brought to you some pretty exclusive stuff regarding their “network vision” well before this was all announced."
It looks like the Epic 4g Touch does not have a rev b compatible radio. Still the best phone I ever owned. Before the OG Evo was on the top of that list.

Where did you hear this? I think I read somewhere that it was.
Better question is can the current Evo 4G handle rev.B?
Just curious.....what is a netword
free the dirk
if the following is true the evo supports rev b
http://en.wikipedia.org/wiki/HTC_Evo_4G
As far as I know, the QSD 8650 supports rev. B, at least in hardware.

I didn't think he was right. But..
The EVO features a CDMA cellular radio that supports 3G EVDO, Revisions 0, A, and the
as-of-yet undeployed B [citation needed] allowingfaster download and upload speeds, and better power efficiency. As well as WiMAX, protocol known as 802.16e, which features speeds of up to 10 Mbit/s on the downlink, and 1 Mbit/s on the uplink. The device is marketed as a 4G phone, WiMAX is considered to be a 4G technology based on 4G
I really hope this is true and that the Evo is able to support it! I'd love to get a boost in 3G speeds. I'm getting sick of how slow it gets sometimes and wimax is a joke, way too spotty coverage and very up/down with it's speed.
I wish I could post the links, but the HTC's spec page for the EVO states a QSD 8650 as the SoC and a search on Qualcomm's site confirms rev. B support.

I don't think our phones are 1X advanced compatible though. I towuld be nice to be able to use REV B it really would.
My guess is that this would very likely be turned on somewhere for trials.. so perhaps people can keep checking their network status page to see that A turn into a B/....
I doubt that the EVO could take advantage of all of these improvements, although I suppose if the chipset supports rev B then that aspect is certainly possible. I know that when network vision was announced it was said that phones with chipsets supporting aspects of network vision (channel bonding, 1x advanced, etc.) would come out in the summer of 2011, but it was never announced which phones had these new chipsets (or perhaps all new phones after a certain date would have them, which makes sense in the long term as every handset on the network that supports channel bonding gives the network more flexibility).
It's certainly plausible that flagship phones such as the EVO 3D or Samsung Epic Touch would be the first to get them.
Edit: Not sure where in that video it states explicitly that Sprint is rolling out EVDO Rev B, but maybe I missed that. There's really not any new information in that video, this is the same basic info that Sprint's been promoting since network vision was first announced. Anyhow, even if the EVO can't make use or 1x advanced or Rev B, network vision will be good for data speeds on the EVO in a couple of ways: First, every phone that has the new chipsets potentially alleviates congestion on the network by allowing the phone to use 2.5 GHZ spectrum for CDMA voice and EVDO when available, freeing 1.9 spectrum for us EVO users. Second, the new towers provide better signal quality overall, so if you're in an marginal coverage area, you could get better signal quality from the new tower. And third, microwave back haul allows Sprint to no longer rely on its competitors when connecting individual towers to the backbone of its network, which provides increased backhaul capacity at lower cost.
The benefits are obviously more direct for phones with the newer chipsets, but every existing handset will benefit indirectly.
