Hi,
3G does not share 'ports' or anything else on the radio network. As load increase, the cell will shrink, but throughput should stay the same. I'll find out why the demo systems are so slow. A bit like going for a test drive in a Porsche with 2 cylinders not running....
What is shared is the connection to the Internet, so this, together with loading of the site you're trying to access, could be a potential bottle neck.
Due to the rapid uptake of the 3G service, these links are constantly upgraded. It's due to double again in the next few days.
Can you remember the actual problem when they tried to install the dashboard on your laptop? (I assume this was what happened?)
If it was a Novatel card and the drivers would not install, this is a known problem with some laptops and there are workarounds for it. Give me a shout, if you need help or call 082-155
The 3G software creates a normal dial-up connection, so if your software worked over dial-up, ISDN or ADSL, it'll work over 3G.
