The organisation will next week show off a Wi-Fi enabled bus at the Paris-hosted Public Transport Exhibition 2004. It will also launch a public trial of the technology, on the number 38 bus, which runs between North and South Paris. Buses on the route have already been equipped with Wi-Fi, RATP said. Travellers will be able to connect their (suitably equipped) PDAs and notebooks with the bus’ on-board access point. However, Internet connectivity is only provided at Wi-Fi speeds when the vehicle passes within range of a fixed hotspot - at a major terminus, for example. For the rest of the journey, connectivity is maintained through a GPRS link. link
