text: A wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. The notable advantage of WDS over other solutions is that it preserves the MAC addresses of client frames across links between access points.
  An access point can be either a main, relay, or remote base station.
  A main base station is typically connected to the (wired) Ethernet.
  A relay base station relays data between remote base stations, wireless clients, or other relay stations; to either a main, or another relay base station.
  A remote base station accepts connections from wireless clients and passes them on to relay stations or to main stations. Connections between "clients" are made using MAC addresses.
