Abstract :
This report shows both, robustness and cost-efficiency, can be achieved in a WLAN over fibre system using IEEE 803.11 protocol. Although it is shown that the fibre delay might violate some of the timing boundaries of the media access (MAC) protocol, with a careful choice of slot time, these networks can benefit even without the need for modifying the existing protocol. The network topology is based on a WLAN-Environment that is used in a subway in Nanjing (China) to accomplish the Trainguard MT System.
