Configuration Notes

Configuration Notes

  • The vehicle-ground fast link handover network is a single-hop Layer 2 Mesh network composed of the AC, trackside APs, and vehicle-mounted APs.
    • The AC is deployed on the ground network to manage and control trackside APs.
    • Trackside APs are Fit APs deployed along the track. They function as MPPs and communicate with the AC in wired mode at Layer 2.
    • Vehicle-mounted APs: are Fat APs deployed in the front and rear of a train. They function as MPs to set up Mesh links with trackside APs.
  • Each vehicle-mounted AP can only use one radio for vehicle-ground communications at one time.

  • On a vehicle-ground fast link handover network, the AP9131DN and AP9132DN can be used as a trackside AP (Fit AP) or vehicle-mounted AP (Fat AP). You can also use the AP8130DN as a trackside AP (Fit AP) or the AP9130DN as a vehicle-mounted AP (Fat AP).
  • On vehicle-ground backhaul links, radios of APs with 802.11ac chips can interconnect only with radios of neighbors with 802.11ac chips, and radios of APs with 802.11n chips can interconnect only with radios of neighbors with 802.11n chips. Table 13-1 lists types of chips used by rail transportation APs.
