AT&T to support HSUPA on all handsets within 1-2 months?

AT&T to support HSUPA on all handsets within 1-2 months?

The battle over who has the fastest 4Gnetwork with most coverage is far from over, but recent outrage overslow upload speeds on AT&T might have given other carriers theedge. After users rushed in reports about upload speeds of lessthan a megabyte on the newly launched HTC Inspire 4G, AT&T replied that the phone simply doesn'tsupport HSUPA. AT&T's 3G HSPA network consists of theHSDPA part for downloads and HSUPA for uploads. In our review,we found upload speeds to peak at around 150kbps, much lower thanwhat the Inspire 4G should be capable of. What is the reason?

HSUPA is most likely present on thehandset, but for some reason it seems disabled in the firmware, so afuture update might fix the issue. Latest information by a sourcequoted by Engadget points to the 3GPP protocol as the mainissue behind this. Currently, AT&T handsets authorize as 3GPPRelease 5 devices on the network. This might not mean much to you,but what matters here is that the fifth version of the protocoldoesn't support HSUPA. The updated 3GPP Release 6, however,does, and as soon as AT&T allows devices to authorize as Release6, the magic of fast upload speeds will happen. There is oneexception to the rule and not surprisingly it is the iPhone 4. Thehandset uses the sixth release, which grants it much faster uploads.

Well, this solves the mystery, but justwhen are the higher speeds coming? AT&T is believed to allowother devices to use 3GPP Release 6 within 1-2 months. So,let's wait up, it should be well worth it.

So you say that iphone4 has release 6.. so does this mean that it will be able to take some what of advantage of 4g speeds?

no, this is specifically for the upload radio, not download. HSDPA/HSPA+ is down HSUPA is up.

I dont have At&t but if this is true how can they advertise their network as 4G when it doesnt deliver suitable upload speeds and subpar download speeds. I am not trying to start a war but I did a speed test this morning. 3 tests and avearge speeds were between 5-6 Mbs dwn and 1.5-2 Mbs up in the suburbs of Md/Dc area. Thank you for Sprint 4G :-)

i get that or higher on my vibrant 3g dude. wimax may technically be a "4g" network, but its over populated and under delivers like crazy. especially for the 10 dollar "4g" charge.. and soon to be 10 dollar "smartphone" charge they are tacking on. My wifes G2 kicks around 7-11 most days in hspa+ and we dont have any surcharges for that. :)

next time you test it, go to settings, about phone, and check the data connection. Id bet money its saying HSDPA not HSPA+. That little "H" indicator is a lie and shows up while ur on 3g as well. If your sitting in HSPA+ and get that speed, id be very suprized. zoooom baby! lol.

Meanwhile, 75% of att territory is sitting in 2g coverage. It's laughable that att aspires to be one of the leaders but can't even run a modern network that works in cities or rural areas. Pathetic.

Bai, 75% of the territory is not in 2G, but in 3G - HSPA+ is just faster 3G. It is funny, because I bought a captivate, rooted it and have a PHOENIX rom on it that gives me the H symbol for data. I get 3-5 mbps upload and 1-1.5 mbps upload - the rom has the modem software necessary to do this. You would think that AT&T phones would just simply come with that ability so when a user is in the HSPA+ territory that it would have the speed. It seems to be more of an issue with th 3GPP protocol. But, then why does T-MO have some users getting 6mpbs? It would be nice if AT&T released a phone that was not neutered. Thank you, XDA!!, for making my cappy awesome.

Seventy-five percent of At&t's network is still 2G, but what your getting at is true; the majority of their potential customer base resides in 3G areas. Nevertheless, At&t always has an excuse to cover their claims with. Their coverage in my area has gone steadily downhill over the last 9-12 months, and even the recent upgrades to 3G here haven't done much good. I'm hoping other At&t customers are having better luck than we are here. T-Mobile's EDGE is faster than At&t's 3G in my region.

I usually get about 2.5-3 mbps download and 0.4 mbps upload on my inspire and 2.5-3 mbps download and 1.5 mbps upload on my iPhone 4. So hopefully they will send out an update soon. I could root the inspire but I really don't feel like the hassle. On a side note, the inspire is a complete data hog. I have used 1.5gb of data in about 3 days. Good thing I still have unlimited data.

NO 4G for ANY never installed the 4G hardware..3G only

They sold the phone as 4G without 4G speeds, knowingly. I should sue them but I'm returning this slow device.
