Alex Russell posted his slides about which he used at EuOSCON. On slide 19 he has a table listing the TCP init times on a couple of cellular networks:
| Network Type | TCP Init Time |
|---|---|
| GRPS | 5 - 7 secs. | 3G | 12 - 15 secs. |
Alex focuses on HTTP since calling him a maestro at JavaScript is an understatement. Obviously this is an issue for the subject of his presentation: mobile AJAX. There is an obvious solution to sending little snippets of XML without the TCP overhead: a better protocol.
I could name at least one that could deliver for AJAX along with providing a feature set required for cell phones. I'll leave it to you to guess.
