[Q] "Mobile Network Type" Question with AT&T

---

I got my Infuse a few weeks ago and while I'm happy with the speeds over the Captivate (which never seemed higher than 2mbps) I don't think I am getting HSPDA speeds.

With 2-5 bars I am averaging around 1.5-3.5mbps in and around Boston which is all covered by AT&T's "4G" service (Im only talking HSPA+ here not LTE). My highest was 6.7mbps and 7.4 mbps once a week or so ago.

In looking at my "Mobile Network Type". I think that I am very infrequently if ever seeing it say HSPDA. It generally says UMTS.

Am I correct in saying the UMTS is the 3G service that basically the IPHONE gets?

Is anyone else out there seeing faster speed and their "Mobile Network Type" say HSPDA regularly?

UMTS is ATT's basic 3G service...and is generally a very slow network but has a big coverage base....

HSPA is the newer 3G service which gets even better speeds but it still limited in some areas.....An iPhone as you mentioned will connect to UMTS or HSPA depending on cell tower location......HSPA+ which is what the INFUSE connects to is nothing more then HSPA with better backhaul for higher speeds but has the same coverage and range of regular HSPA.

HOWEVER, the way it works is that it connects to the STRONGEST signal at the time, if UMTS is outputting a stronger signal from a cell tower you will latch onto that one more often then HSPA....

At work and traveling to and from, i am usually on HSPA, but at home that signal is weak (location of cell tower with HSPA amplified) so i am usually on UMTS...

actually hspa runs on top of umts and only switches when you start downloading. if you idle, it should say umts.

That's not always true, it depends on the cell site architecture the device is pinging - my device and many previous device idle on HSPA frequently and in other spots, UMTS.
