Dear, friends
I 'm study about UMTS network and metodology, and I still have some questions about, what kind of parameter that used to migrate from 3G network to HSDPA?, sometimes, when we were download via 3G, and then after a few minutes later, the network we've used was change to HSDPA, shown at the indicator on our MS. Please show me the reasons or Literature.:)
Thanks B4..

Hi,
HSDPA uses a modulation adaptive in its transmission. It depends on the SNR of the received signal.
If it is high it can use a modulation more efficient (16-QAM) and an increase in throughput.
The same hapens when you change from UMTS (QPSK) to HSDPA (16-QAM).
There is also some configurations from network side at user profile so that there is a capacity balance between the users, but this is dependant on the operator policy.

Nice Doc...
Thsnks!
Hi Madeira, could you please share your documents in another way? I cannot access them. I would like to know what are the throughput speed for different services for HSPA and their relative CPHIC (dBm) thresholds.
Thanks

Hi guy,
You should not post docs without password, because it is useless if SO downloaded it.
