AT&T close to completing HSUPA

I just double checked my speed, and I'm still at 1600k down and 300k up here outside Washington DC.

1400kbps will be more than 2x faster than any cable or cellphone companies offer in my area. i consider my area typical suburb/semi-rural.

for some reason though i think that yahoo got their facts wrong. most DSL's that are called 1.5MB are 150kb.

so 1400kb would be 14MB

anywho, im considering an aircard as well.

 

Most 3G devices on the market now are only capable of 3.6 mbps. To get those predicted speeds available in the future you will have to upgrade to a new device at that time.

So AT&T's network is pretty "SUPA":browani:

 

What is strange about that article, is that they mention AT&T upgrading to HSUPA, but no mention of increasing the downlink speeds? Usually operators add HSUPA in order to facilitate higher rates in the DL. But they just say 1.4 will continue to be the max rates.

Are they not going to increase the DL rates due to something like bandwidth issues (having GSM and UMTS on the same bands)? Or will they increase the DL rates later, and just want to keep it quiet for now so people don't start bugging them about it?

What? I think you're forgetting 8 bits = 1 Byte

1.5MB = 12 Mb
...
1400kb = 1.4Mb

...was it a joke (in which case I just ruined it )?.... or am I missing something?

Check what category your HSDPA card or phone is and you can see what bit-rates it supports (scroll down to HSDPA UE Categories). I think Category 5 (3.6 Mbps DL) is the most common one right now available.

I found that my 1.5Mbps DSL gave about 150kBps downloads. So 1440kbps should give about 144kBps. Enough for now, especially mobile.

i was saying that i think yahoo's article is wrong basically. it is faster than 1.4MB by the way companys are measuring.

 

on my 3G phone tethered i did 596kb DL with 4 Bars. That is with regular HSDPA i believe. thats almost what my DSL Extreme 6.0MB will do.

 

Does anyone know what the last 6 markets are?

 

just and observation: The article headline is a little misleading IMO. If you read he story, AT&T actualy says they will have the high speed deployed on their entire 3g network (i.e not the large parts of their netwokr that still do not have 3G yet)), not their entire network.

 

I got that when I read it...

This does seem to be at the lower range of what HSDPA/HSUPA is supposed to do. Odd.

A little more detail on this from Infoworld. One interesting thing is that they are going to increase the upload speeds to make it almost symmetrical.


AT&T speeds up 3G network
The upgrade has provided a 20 percent boost in downlink speeds

By Brad Reed, Network World
June 04, 2008

AT&T said Wednesday it has upgraded its 3G wireless network to reach downlink speeds of up to 1.7Mbps, a 20 percent increase over previous top speeds.

AT&T says the increased speeds are the result of upgrades to the HSPA (High-Speed Packet Access) network that the company projects to complete by the end of the month. HSPA is a mobile broadband technology that is comprised of two wireless broadband protocols, known as HSDPA (High Speed Downlink Packet Access) and [HSUPA] (High Speed Uplink Packet Access), that operate on 3G mobile devices.

The company says it will have deployed HSUPA across its entire 3G network by the end of June, and it will result in uplink speeds of 1.2Mbps, a 50 percent increase over its previous peak uplink speeds of 800Kbps.

If the previous uplink cap is 800, how come i can barely get over 300 upload?

-Jay

 

I'm not sure. Perhaps it's because "peak uplink speeds" are only available on alternate Tuesdays at 3:00 AM. Or maybe it's because hype ≠ reality. :lmao:

shared pipe. so if your in a busy area or time of day etc your results may differ. also device may play a part. some things are still processor and memory limited. even a tilt.

 

I don't understand. Standard UMTS has uplinks of only 384kbps max. HSUPA rates start at 730kbps. If they currently have 800kbps in their network then they allready have HSUPA.
High-Speed Uplink Packet Access - Wikipedia, the free encyclopedia

Probably because HSUPA isn't enabled in your area. The max uplink rate with standard UMTS is 384kbps, which sounds like what you're getting. HSUPA starts with uplinks at 730kbps. I guess AT&T has it in some markets, but maybe not all. Ask people in your area if they have ever clocked an uplink at faster than 400kbps.

...or maybe your phone doesn't support HSUPA? I think the Tilt does, but check the specs somewhere.

 

i think all 3G devices on the market now are only capable of 3.6 mbps.

 

I am the nerdiest phone-dork I know. None of my other friends knows how to teather their phones.

just make sure you don't go over the cap

 

True, on my 5 Mbps cable, I can grab 5 GB in less than 3 hours if I'm grabbing torrents. Browsing for the same time for me is about 200 MB--and that's WITHOUT looking at porn.

 

Shared pipe is a part of it, but so are link conditions. With a weaker or noisier signal, you'll get a slower connection due to link adaptation. The modulation type is varied (complexity of each symbol), coding rate is varied (amount of redundant data in the data stream), and HARQ can be used (send portions of the data again to reconstruct it from errors).

Here's a good Wikipedia Link:

I don't think the device processor and memory will limit transmission speeds from what the device is rated at, other than limiting the requests for data. Basically, if you request a chunk of data, it will come at full speed, but you may not request another chunk of data very soon. For tethering, this should not be an issue. We're not talking about a lot of data here. USB 2.0 implementations toss around 480 Mbps--I'm sure even a basic flip phone could saturate a 7.2 Mbps connection while tethering if it had the radio for it.

 

well cool stuff where in middle ga are u?

 

I'm in Warner Robins. If you're in Columbus, I'm just down 96 from you.

 

Air Force?
