What type of 3G service does Los Angeles have? UMTS or HSDPA?

Tech support says only UMTS is enabled here in Hollywood, CA with average speeds of 384 Kbps at best. Is that true? Others have told me we're in a HSDPA area by now.

Thanks.

hollywood certainly has HSDPA. i go there frequently. in fact, i think all ATT 3G cell sites are HSDPA. there are no UMTS sites as far as i know.

Yeah figures. One of the red flags that popped up is when the girl with data tech support tried telling me that I will roam on Verizon in certain places.

Where do they get these people?

OMG there is no way an att person actually said that!! ha figures. yeah i would just stick to HoFo for any and all network and cell phone related questions. verizon isnt even the same technology!

UMTS is HSPDA, and HSUPA. When UMTS gets HSPDA, and HSUPA its HSPA+, Its kinda like GSM has Gprs, and EDGE.

well sometimes a site does have 3G without having HSDPA. whatever its called, its 384Kbps max vs 3.6Mbps max.

Technically, it would be 'plain' old UMTS, which was what AT&T Wireless originally deployed. HSDPA/HSUPA is a data upgrade similar (but not the same) as what EDGE/EGRPS was to GPRS.

What's the max sustainable (non-theoretical) speed on HSDPA 1.8?

I ask because last night I was maintaining a dl speed of 210-240KB/s, which works out to 1.64-1.875mbit, which is the closest i've ever gotten to peak HSDPA 1.8 speeds, nearly double my average. Makes me wonder if they arent upgrading the backhaul in preperation for the jump to 3.6?

i would say that might be a 3.6Mbps tower. 240KB/s = 1920Kbps which means its over the 1.8. that said, i have never gotten those speeds anywhere in socal. i'm in temecula kinda near riverside.

OMG, RogerPodacter, you sound just like a 13 year old girl! He did not just say that! He did! OMG, no way!

But, seriously, there is a way an AT&T "person" actually said that, because an AT&T "person" *did* actually say that.

The dregs of our high schools, GED programs, and community colleges. To most of them, wireless is nothing but a paycheck. They have no intellectual curiosity about the industry or its technology. But, to their credit, they probably lead more fulfilling lives than those of us, myself included, who are far too absorbed in this pastime. Ignorance would be bliss...

The tower in question is Site ID: 12410 on www.atttowers.com

The download was on an AT&T Tilt tethered to a laptop, downloading a single file from a private server (100mbit) - it maintained speeds above 210KB/s fluctuating up to 240KB/s for the duration of the download (10 min or so)

The fastest i've gotten on that particular tower before was ~140KB/s, on a blackjack tethered to the same laptop.

I'll do some more testing next time i'm in the area.

I just picked up an 881U, and over here in Riverside i'm showing a 3.6mbps connection in the software.. speed tests are hovering about 1500kbps average though, so it looks like the backbone is still limited.. the max speed I got was 205KB/s, it flutuated quite a bit though, the average was around 185KB/s.

Not sure when it was upgraded to 3.6, because I never had a device that specified what speed it was connected at before. But that's a least 2 towers in my area that are 3.6..

yeah recently i did some speedtests teatherd with a tilt, and got similar speeds, looks like 3.6 is starting to go live, either that or the HSDPA reg edit in Kaiser Tweak does what it says.
