Default Difference between HSDPA:11 and HSDPA:9?

I have been having constant reception issues on my galaxy nexus in areas that I normally get full service.

Ive tried just about everything to no avail. What I have noticed though is that any time i have a good signal and phone is actually working I am usually on HSDPA:9. Other times when my signal is fluctuating or gone all together its on HSDPA:11 and cycles to UMTS:3.


Does this make sense or am I just imaging it.

From what I'm told, this is normal behavior. The phone will hotswap into HSPA+ mode during data transfers, but then scale back to 3G when there's no data being moved around. I'm told the phone does this to save battery.

I Googled to here to look for the answer to the OP's question (Difference between HSDPA:11 and HSDPA:9?), but it seems elusive. Nothing else seems to answer it either.

I speculated that the number after the colon refers to the Category as per en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access, but it doesn't seem to fit. I also looked at whether the number after the colon has to do with speed (in Mbit/s), but there's no HSDPA for ~8 (the nearest are 7.2 and 10.1) nor ~11 (nearest are 10.1 and 14.0) and UMTS:3 makes little sense as well.

Anyone?

It's the HSDPA category number. 9 is HSPA, 10, 13 and 14 are HSPA+

Damn. I had assumed that 11 was going to be faster than 9. How misleading.

Actually no, you're totally wrong. As hillrider is.
The number represents a different type of general data connection, not every type of HSPA connection. And 9 is not for HSPA, etc; (before 9, it even writes HSDPA clear as crystal). As for 11 it writes HSPA.

So, from what I have noticed so far:
GPRS - 1
UMTS - 3
HSDPA - 9
HSPA - 11
LTE - 13 (? I'm not sure here)

So it's pretty obvious these aren't part of a HSPA table, because of the different technologies listed. They are a part of a general data connection table. Also, it's pretty obvious that they are numbered in ascending order, based on the connection speed. There are probably even more, I don't know exactly.

If you read something else here I misread.

I have seen UMTS:3, HSDPA:9, HSPA:11.

I would be pissed if the numbers actually meant HSPA categories because I think it would mean my provider is lying when they say they provide HSPA+. For that I'd need to see HSPA:13 and I never have.

HSDPA is in the DOWNLINK
HSPA means HSDPA + HSUPA with HSUPA meaning data in the UPLINK

Hmm yeah that makes sense. I should have known that. I'm not sure why I got confused there. Thanks
