I have an SE C905 & displaying on the screen next to the signal strength is a box with "H" in it, it fluctuates between a H & 3G, mostly showing "H" anyone known what the "H" means please?

thanks Steve

Its HSDA or HSPDA (not sure atm!)
Basically, its what the phone uses for data transfer when there is not a full 3g signal.

Why do you think that?

High Speed Downlink Packet Access is a faster 3G connection.

HSDPA to 3G is essentially what GPRS was to GSM.

GSM: 2G
GPRS: 2.5G
EDGE: 2.75G
UMTS: 3G
HSDPA: 3.5G

Technically though, 2G (second generation) is the name attached to GSM, GPRS and EDGE, where as 3G (third generation) is the name attached to UMTS and HSDPA.

Ok, fair do! Im not sure where I got the idea that the phone "dropped down" to HSDPA if there was not a full 3G signal.

My bad!

Can I correct you there?

And then on certain handsets you have h+ for hsdpa

Thanks all, so when the symbol changes from "H" to 3G, 3G is slower than "H"?

I thought H+ indicated HSUPA (or HSPA) and H was HSDPA.

HSDPA 3.6mb (H)

Isn't that implying one is a faster version of the other?

Only in the way E is faster than G.

But surely they are VERY different things. HSDPA relates to stuff coming to the phone, HSUPA relates to stuff going from the phone.

However, the improvements which give a faster upload also enable a faster download.

Really? I have not heard such a thing. HSDPA facilitates a faster and more efficient download. HSUPA does not. Unless you can point me in the direction of something which says otherwise.

From what you are saying, when T-Mobile became the first HSUPA-enabled network we'd all have seen an increase in our download efficiency. Which isn't the case. What did improve download efficiency was upgrading the HSDPA network.

Let's not forget the ASA forced Voda to change their ad copy because of those spurious claims.
