Participating vehicles 9 communicate with egress points 10 according to an infrastructure mode method in which participating vehicles and egress points create, transmit, and receive beacon service table packets, vehicle service table packets, and/or packet bursts. Participating vehicles also communicate with other participating vehicles according to an ad-hoc mode in which beacon service table packets, vehicle service table packets, packet bursts, or positive acknowledgement packets are created, transmitted, and received between participating vehicles. Egress points create and transmit enhanced beacon packets or negative acknowledgement packets. |
