im sure google has been talking with tmobile and htc about 4g, whether it be wimax or LTE. can anyone confirm if it supports either? not only would that make the phone more awesome, but we could be more certain on tmobile 4g plans. i mean sprint already has it on the pre, and google gave the n1 specs to beat out most opponents (asside from the hd2, but i dont think that supports 4g either :/ never looked).
any idea or confirmations would be welcome
damn. oh well, the 3g boost is good enough for now
What a bollocks question. Networks won't be that mature for AT LEAST 18months.
LOL. i didnt think it would, but it wouldnt surprise me if google did have htc put it in
Knowing HTC they will stop supporting this phone in 6 months. £100 says the Nexus 2 will be out by Christmas.

T-Mobile has no intentions, as of right now, of going to 4G. Its simply not needed. Explanation: Sprint and Verizon are CDMA technologies. CDMA (Code Devision Multipable Access) has a 2.5MHz bandwidth. With that they use EVDO for thier 3G data rates but because of the bandwidth of CDMA they are very limited on their max download speeds. With that said, both carriers will have to go to 4G, WiMAX or LTE, in order to achive high data rates.
On to T-Mobile: T-Mobile has recently installed a UMTS 3G network which uses WCDMA (Wideband Code Division Multiple Access). WCDMA has a 5Mhz bandwidth which, by easy math, is double the capability of Verizon and Sprint. UMTS uses a technology called HSPA+ for its data. HSPA+ is capable of download speeds up to 48Mbps. As of right now, T-Mobile is making efforts to seriously increase their data speeds using HSPA+ and as of right now T-Mobile has HSPA+ launched in Philidalphia and is getting great reviews.
So, with all of that said, hold on because by the end of this year T-Mobile will probably have the fastest network.
Why 4g on a phone, if 3.5G 7.2Mbps worked fully, its more than enough, for youtube, iplayer and daytoday surfing.
22Mbps from mobile, networks - its a joke max speed will be about 4-6Mbps if one is lucky and much less in most areas

So when all this happens according to planned, and hoping it will. Will current phones now(Nexus One) be able to benefit to the new speeds?
not necessarily all current phones, but the nexus one does... when you take a look at the specs, there is HSDPA and HSUPA... the more common nomenclature would be HSPA+ and HSPA as some people like to put it...
with the upgraded network speeds that t-mobile announced as of the fifth, my average download speed has jumped from 600kbps max to 1 mbps on my nexus one... a pretty hefty improvement, and its only gonna get better... don't really see the need to upgrade to anything faster at the moment because most cell companies can't handle the load of data thats going across their networks as is... they upgrade speed, they have to upgrade capacity too and that means more hardware, its not as simple as swapping to HSPA+

HSPA (High Speed Packet Access) and HSPA+ (Evolved High Speed Packet Access) are actually 2 different things. HSPA is capable of up to 14Mbps down while HSPA+ is capable of up to 54Mbps down. T-Mobile is currently running HSPA nation wide and running HSPA+ in Philidalphia. T-Mobile hopes to be running HSPA+ nation wide. HSDPA and HSUPA are simply HSPA with the D for Download or U for Upload added to the acronym to differntiate the different up and down speeds.

On a mobile device, where there are other factors involved, such as cpu and other performance components.
My phone speedtest gets 15Mb on wifi and about 3.5Mb on 3G but the real life speed when using the internet seems much slower even with wifi because the device can't handle or process the web pages as fast as a PC, also i doubt people will use rapidshare on the phone where speed matters,
For genral surfing a good 1MB connection is enough for mobile devices, i think anyway.
I use usb modems by huawei i have many most have 7.2Mbs with vodafone i get 3-5Mbps but still seems very slow, mostly due to the ping which are normally in the 300ms+
ADSL/DSL is best for speed, mobile BB even at 50Mbps will not compare to 20Mbps DSL line. As DSL is much more stable and Mobile BB is NOT very stable

Now if they could just get 3g in my area this year.....
Personally, I'm not happy that Sprint has decided to go with WiMax. On one hand, we've always been kind of blocked from using imported phones... but on the other hand, Sprint wasn't the only CDMA carrier in America, and there were enough other companies using CDMA elsewhere in the world to ensure that we got to have phones that were at least as cool (often, better) than what Europeans could buy for GSM (especially with regard to the first PalmOS PDA phones, and generally with regard to Windows Mobile PDA phones).
As far as I can tell, Sprint is the only carrier on *earth* going with WiMax instead of LTE. It's one thing to be limited to the same phones used by Verizon, just about everyone in South Korea, plus half of Australia, South America, and a big part of China. It's another matter *entirely* to be the only 20-40 million people on Earth stuck with phones that literally have no market anyplace besides Sprint in the US.
I remember going to an AT&T Wireless store with a coworker in 2004, right before they switched to GSM. I looked around the store, and couldn't *believe* anyone wouldn't take one look at the 20th-century relics they were still selling to new customers and run from the store screaming. That's what being REALLY "ghetto-ized" means.
We won't even be able to ***** about Sprint not supporting R-UIM cards, because there won't be any non-Sprint phones that are even capable of working on Sprint.
I've been a Sprint user since ~1999, and it really hurts to think I might eventually be forced to choose between leaving Sprint or settling for a second-rate phone that sucks as badly as AT&T's TDMA phones did relative to the phones Sprint, Verizon, and even T-Mobile had at the same time.
The biggest selling point I've seen for WiMax so far is the fantasies some people have that it will replace WiFi... totally overlooking the fact that people don't use WiFi because it's the best... they use it because it's free. It uses internet connectivity that someone's already paying for, and enables its use in more ways. It's the same reason "3G tablets" are going to flop (in the short term, at least) in America, unless they can ALSO use WiFi and tether to cell phones. Very, very few people are going to willingly throw down $500 for a new device that requires yet another new $10-40/month fee to use it unless it's literally god's gift to the computing universe. AFAIK, nothing remotely close to being *that* cool is hitting the market anytime soon.

HSPA from Wiki...
HSPA+, also known as Evolved High-Speed Packet Access is a wireless broadband standard defined in 3GPP release 7.
HSPA+ provides HSPA data rates up to 56 Mbit/s on the downlink and 22 Mbit/s on the uplink with MIMO technologies and higher order modulation (64QAM). MIMO on CDMA based systems acts like virtual sectors to give extra capacity closer to the mast. The 56Mbit/s and 22Mbit/s represent theoretical peak sector speeds. The actual speed for a user will be lower. At cell edge and even at half the distance to the cell edge there may only be slight increase compared with 14.4 Mbit/s HSDPA unless a wider channel than 5 MHz is used. Future revisions of HSPA+ support up to 168Mbps using multiple carriers[1].
HSPA+ also introduces an optional all-IP architecture for the network where base stations are directly connected to IP based backhaul and then to the ISP's edge routers. The technology also delivers significant battery life improvements and dramatically quicker wake-from-idle time - delivering a true always-on connection. HSPA+ should not be confused with LTE, which uses a new air interface.
As of November 2009, there are 20 HSPA+ networks running in the world at 21Mbit/s and two are running at 28Mbit/s[2]. The first to launch was Telstra in Australia in late 2008, with Australia-wide access in February 2009 with speeds up to 21Mbit/sec.

Right, but T-Mobile (US) only has HSPA rolled out right now. HSPA+ won't go until later this year from what I read. Overseas, it is probably HSPA+ given how Europe is always one-step-ahead in terms of the cell industry ('cept for the HD2, which T-Mobile US got the better version ).
High-Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, also coined 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.0 Mbit/s. Further speed increases are available with HSPA+, which provides speeds of up to 42 Mbit/s downlink and 84 Mbit/s with Release 9 of the 3GPP standards.[1].
I understand but, I am in las vegas,nv and there is no H available here as far as i know. It was showing 3G before the ROM was flashed, and no matter what rom i try i get H. I just want to be sure i am not getting a slower speed.
Thanks

Same here and I am in Minnesota. I would guess it is just a bug in the ROM or something not working 100% correct. You can always verify your speeds by doing a download test. I did a speed test here when I saw the H and the latency and speed was no difference.
Hey guys, I stooped into my local store to show the Reps that I am getting HSPA and they were stunned and pulled up there technician map that shows where they are currently testing for different things and it did show that they are testing HSPA in a large portion of the country including my area. This is really good news because from what I was told my area just launched 3G in late December. I am hoping that everything goes as planned and they just flip the switch for good soon. If that is the case then the HD2 will be just as good as the Evo 4g. Sprint 4G is about the same as T-Mobile HSPA, and I am not gonna worry about an extra 3MP camera and 720P video. My HD2 takes amazing photos as it is and rally nice videos that look at least DVD quality if not better and I am not all that worried about the HDMI out.
i am in dallas and i get H all the time there were like 5 cities that got it just last week
Another thing to keep in mind is when a rom cook makes his rom its very easy to change the '3g/E' icon in the shellres to show an H.. its like me adding an 'L' icon instead of 'E/3G' and saying its on "LIGHTNING SPEED" get me ?
By default most custom roms are not set to use the 3g icon. This is MS's doing not the chefs. In Advanced Configuration Tool you can tell it to use the 3g icon by going to \Data Connections\HSDPA icon: and setting it to disabled. Alternatively you can change it with this reg:
Code:
[HKEY_LOCAL_MACHINE\Software\OEM\RIL]
"EnableHSDPAIcon"=dword:00000000
Please be aware that your are not using a different type of connectivity than from the stock rom.

welcome to the real fast world. nice to see the USA will involve into 'modern' society
I used this ROM too and was always on H. I'm speculating here but I don't think I was getting any faster speeds and since I saw the H constantly was thinking since he cooked this rom he edit it so it always shows on H.
Speculating nothing more.
i've noticed that when my phone is displaying H my speeds are insane.
For example I downloaded opera 10 with flash which is about 5-6mb's.
Under H the download meter is moving at a steady speedy rate.
When my phone drops to 3g i ca nsee the download speed decrease.
IF YOU SEE H MORE THEN 3G wow i envy you.
Only worry about seeing E. Capish?
I wondered about this when i first moved to android 2 years ago and i started noticing H I did a wikipedia search and that helped me clarify my doubt

I didn't think Seattle had HSPA yet (in fact, I read a newspaper article last week explicitely stating that we did not), but my phone switches between 3G and H periodically.
Well I still get 3G in some areas, H in others, and still get E when its there..so i guess this is a good thing
For a long time now
Guys, this has been happening for more than 2-3 years now. Both on ATT and TMOUS (after they switched to 3G).
I have seen H in TyTN/Kaiser/Touch Pro/Xperia before the HD2. But never noticed any diff in speed for better or worse.

You get HSPA. T-Mobile branding removes H icon. It also happens on my T-Mobile TP2, "H" is back after flashed to CHT version.
I have the stock TMo US Rom. What reg edit can I use to enable the "H" icon? I really dislike that they went to the generic "3G" icon rather than E/3G/H. Thanks everyone.
Does anybody try this with HD2? This can "unhide" H icon.

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.
Many of us are so geeked about 4G speeds....the mytouch 4G sprouting about its HSPA+ network which is supposed to make this a better phone and such, but it's all hogwash. I found the article below very interesting and rather revealing as to how these carriers manage to soup us up and get us to believe what they want us to believe, true or not. Sad, but very enlightening.
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 understand all that. But here is my newbie question:
Can the 4G TMo devices (say myTouch4G or G2) really attain quicker d/l speeds than a 3G device like Vibrant? If so, how?
I have not been able to read a clear explanation of this anywhere. Also, TMo says their network will hit 21Mbps in 2011, and that is backward compatible. If so, then why is a 4G device needed?
Call it 10G if they like its just a name, I dont care as long as the speed meets my need at a reasonable price.
because our phones are only capable 7 mbps while the g2 and the mytouch4g can go to about 14 mbps (not even 21) ... but yeah thats why ... its hardware related

They are backward compatible, for example HSPA+ will give vibrant which does not support HSPA+ a speed boost, just not fully benfitted. Same story with USB 3.0 and 2.0
4G is 100 mbps and TMobile will be 21mbps. None of these networks will have 4G speeds and all in fact are upgraded 3G speeds. AT&T will be usding the same HSPA that TMobile will be using and eventually they also will be at 21 mbps.
How any of these carriers can call themselves 4G is beyond me.
Actually the 4G spec calls for 1 Gbps stationary speed, the 100 mbps is the minimum while mobile so it will be 5 years before you really see that.
T-mobiles current "4G" Network is currently running at 21 mbps, with 42 mbps a software upgrade away. So while they don't meet the true 4G speed threshold, neither does sprints current 10 mbps wimax, or verizons 12 mbps LTE. When sprint and verizon first launched their "3G" networks they didn't meet the requirements for at least a couple years, and we are not any worse off due to that flexibility.
I still roll with a 7.2 mbps vibrant and I will be honest, there has not been any time where I had good 3G speed that I needed anything more.

when USB 2.0 came out it allows for higher speed transfers etc....
You will only get 2.0 speeds on a 2.0 port.
The USB 2.0 device will work in a 1.0/1.1 port, but it will not give you 2.0 speeds.
if you want, just replace USB 2.0 with HSPA+
and replace 1.0/1.1 with HSPA7.2
Let me try to shed some light on things for you.

But here is my newbie question:
Can the 4G TMo devices (say myTouch4G or G2) really attain quicker d/l speeds than a 3G device like Vibrant? If so, how?

Yes. Without getting all technical, it has to do with how the data is compressed and encoded on the different channels that the phone and cell towers use.
HSPA+ is an improved version of HSPA. HSPA is an addition to UMTS 3G which allows for faster data transfer rates than just regular UMTS 3G.
I have not been able to read a clear explanation of this anywhere. Also, TMo says their network will hit 21Mbps in 2011, and that is backward compatible. If so, then why is a 4G device needed?

You won't find one unless you do some real digging and learn enough to understand some basics of UMTS. True 4G does a lot more than just give faster data rates. The entire back-end of how the cell towers and core network route information is different. The way the radios in the cell phones work is different and the way the cell towers organize data is different. The benefit is more efficient mobile communication service.
The way things are with 3G, it is difficult to balance voice traffic with the ever-increasing demand for data traffic and maintain QoS for a large number of users simultaneously. Anyone who has tried to use AT&T 3G at a football game or concert can tell you how crappy the service gets when the towers get loaded.
Yes But Marketing.......
All that tarzanman said is correct but the larger picture is just perception and controlling it.
Basically, we really do not have 3g unless you really get somewhere close to 7mg speed consistently........We do not and i am ok with my 2-3mg speed it is plenty good enough for my needs.
Here is a good analogy......when front wheel drive car first came on the market they were hailed as a breakthrough in making a car handle better allowing more room in the car and being safer. The fact is only a little more room is the real benefit and the rest....well, it is just cheaper and easier to mass produce. The car handles poorer than a rear wheel car or 4-wheel. But, they convinced most of the dopey-ignorant customers/masses and even to this day people still think they are better. Moral of the story.........control the message and control the spin, and to hell with facts........ because most don't care they just want the latest "craze jargon" on their lips so they feel cool...(sorry for the rant)
I have had a cell phone now for 27 years.......and here is my advice:
here in the USA --go with T mobile for now watch the business trends and when they start acting like Verizon and Att then look for the next up and coming carrier and then go with them.. That is the only way to have decent, reliable and fast connection speeds for a reasonable prices.
Who cares? As started in the article ITU's decisions hold no water. They have no authority and their definition is arbitrary. I'm in the product development industry, and when our end product goes through a redesign or significant optimization it gets a generation bump. We're now up to third generation. Product looks the same for the most part, but performance increased as a result of engineering changes.
For the wireless industry, all carriers are implementing significant performance increases through network upgrades. These upgrades are not 100% compatible with current generation devices. As far as I'm concerned that's worthy of a generation bump. People are splitting hairs for no reason. It's quite silly. If I were an engineer for any of the major carriers right now I would be pretty annoyed with this ITU business by now.

It is easy,
HSDPA+ (TMO), EV-DO(Verizon), LTE(Verizon) and 802.16e Wimax(Sprint) are considered 3G Transitional.
LTE Advanced and 802.16m (WiMax "Advanced" if you want to call it that) are 4G.

Verizon can call their LTE whatever they want but the fact is it isnt as fast as TMobiles HSPA+
i rather have true unlimited 3G than some bologni 4G with a 5Gb cap. May be is too much to ask for.
Remember, Most tout 4G more or less as 4th Generation rather than true 4G. Although marketing says otherwise. It's a ploy to get your service, just like spray painting your head makes you look like you have more hair. I don't care what they call it, as long as it benefits my speeds.
For companies that have actual caps. its stupid that they are increasing the speeds that you hit your cap. So you may have better speeds to do more, but really you are just hitting your cap faster so you can pay them more money.

lol are you serious. wikipedia is not even a credible source and ANYONE can go in and change the info.
Actually, that wikipedia article is pretty spot on.

indeed it is. And unless you want to read a few 700 page books on the differences between UMTS/WCDMA/HSPA, and LTE/LTE-a, that's about as good of a source as is available at this point.
And as to the OP - it's all about marketing. Technically speaking, 1xRTT and EDGE are both 3g technologies. But cell companies hyped up EvDO and UMTS as 3g, to simplify it for the American consumer.
And so they're marketing their next generation of networks as "4g", even though that doesn't meet up with what the ITU defines as 4G on technical terms.
Again, this is all because cell phone companies know that people buy into the hype rather than concern themselves with the details.
But in the end, who gives a damn? It's significantly faster than what people used to expect from 3g (ie 1-2mbps), so as long as the results are better, they can call it 9000G for all I care.
All of this 4G related discourse is exactly what the carriers want. Four gee shmoor gee. I'm just happy I get 3-5 mbps down where I live.
In the end, we are all just stupid pawns

It doesn't matter, wiki bashing is in vogue even if one doesn't have a clue if the article is accurate or not.
Wikipedia 4TL!
Finally,
Smart-PLDT has upgraded its fiber optic lines and is now the nations pioneer in LTE Broadband and Mobile Service,
Core Benefits:
-Only Php 3,000 ($71.43) for 1 month REAL UNLIMITED LTE (NO CAPS last until October 25 2012, after that there will be a 10GB cap)
-Free phone with LTE Coverage
-NO ANTI-TETHERING ****
More info here:
Smart LTE
Unlimited 4G LTE SMART
Competitor Globe Phils. will announce its LTE service October 2012
Great news
I really wanna know what's the maxmimum speed the can offer with LTE. Well actually I'm not really expecting anything higher than 10mbps.
Also the 10GB throttling is breaking the LTE support. You're being given high speed internet yet you'll only be able to achieve that in a very2 limited time. That's just 2 bluray movies.
we have 42MBPS here in cebu

42MBPS wireless?
If it's a line then I'm not shocked but if it get's 42MBPS from a wireless internet then @[email protected]

its in cebu city, IT park
so you won't be surprised why we got those speeds since the regional central office is like half a kilometer away
That's what T-Mobile USA uses, DC-HSPA.
not true 4G
guys, I just want to clear this up. 4G is a specific set of international cellular wireless standards. to call itself 4G, a network must meet a set of requirements laid out by these standards. quoted from this site. it says that 4g should be at least 100Mbps (megabits per second, note the small letter b). yet, the IMT-Advanced specification considers them as 4G for as long as there is "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed" (ref).
afaik, smart and globe's maximum network bandwidth is only 42Mbps (see smart and globe). globe even claims that their WiMax and HSPA+ are already 4G, which is technically not true. most of the users of globe and smart still reports disconnection and delays when using data connection on their mobile networks. indeed, its a very low quality of service with a high marketing value. poor us.
well whatever that is im still happy to live the day i got 42mbps wireless,
most i got is 334mbps on wired connection on our company's server
hmmm
SMART LTE in Cebu
SMART has yet to officially to activate it's LTE Data Network in Cebu. There's a demo unit at the JUMP store in SM Cebu. Here's an article on it - http://www.wiredmash.com/smart-4g-lte-in-cebu-speed-test/
