According to Motorola's findings:

The trials have shown that video streaming performance degrades when a relatively modest number of users are active. As little as four active users are sufficient to cause video streaming to freeze if scheduling priorities are not set properly. To compensate for this, operators must actively prioritise video over other services or provide more capacity. Operators could defer video services on HSDPA to a later stage, but as video services consume a large amount of UMTS capacity they should be moved to HSDPA for improved efficiency. This will reduce the cost to deliver video services.


Hmmm... CDMA EVDO Rev B, anyone?

Sure Rev B for me! HSDPA does have QoS so you can prioritise traffic based on what services are being used at the time. This could mean you will be bumped from video streaming if voice usage is high.

All Cellular networks have limits on the amount of users on a cell site at one and the data rate dished up is dependant on the amount of back haul.

FYI - tested latency on Rev B is around 26ms. Even commercially if it is 60ms what a massive improvement.

I was also reading an article the other day claiming that HSDPA performance also suffers greatly unless there is very good signal strength and they are predicting some large problems with inbuilding coverage, even where existing WCDMA voice coverage may be fine.

It looks very much like it's suffering from the same issue GPRS had - lots and lots of hype and failing to deliver on most of it. The GPRS claim that it's maximum speed could be 144kbps makes a great Tui billboard! :-)

The entire country will understand Tui Geekboards - Yeah right!

If there was very low numbers (users) on the cell and the network provider made all 8 time slots avaliable for GPRS it would improve things alot
