National Express has announced it will be making WiFi available for free (at least at the moment) on it’s service between London and Cambridge.

The system will work by having a WiFi network on the coach, and then accessing the internet via 3G. At speeds of about 384 kbps it’s nothing special, but with 3G speeds set to increase to 1.5 mbps soon, the service could improve. It will probably also cost money.
