Geez, just how fast do mobile networks have to be in order to deliver the sort of content you might expect from a high speed mobile network of the 21st century? At this point, I guess speeds will have to continue to push forward in order to meet the demand. My question is, at what point do we get speeds that will truly be ‘fast enough?’

That was one of the messages from the mobile industry at the 3GSM World Congress in Cannes last week.

Fast 3G networks are here but the focus has shifted to their evolution into a higher bandwidth service, says the Global Mobile Suppliers Association.

At 3GSM, Siemens showed off a system that transmits faster mobile data.

The German company said data could be transmitted at one gigabit a second - up to 20 times faster than current 3G networks.

The system is not available commercially yet, but Motorola, the US mobile handset and infrastructure maker, held a clinic for mobile operators on HSDPA (High Speed Downlink Packet Access), a high-speed, high bandwidth technology available now.

Early HSDPA systems typically offer around two megabits per second (Mbps) compared with less than 384 kilobits per second (Kbps) on standard 3G networks.
