CWNA Chapter 7: Wireless LAN Topologies

This chapter discusses the various Wireless Networking topologies

  • Wireless Wide Area Network (WWAN): Provides RF coverage to a vast geographic area typically deployed using cellular telephone technologies
  • Wireless Metropolitan Area Network (WMAN): Provides RF coverage to metropolitan area such as a city. WiMAX-802.16 using wireless mesh routers and mesh access points.
  • Wireless Personal Area Network (WPAN): Wireless computer network used for communication between devices in close proximity using Bluetooth or IR.
  • Wireless Local Area Network (WLAN): Provides RF coverage to a building or campus using 802.11 APs and wired backbone. These networks can be managed locally, remotely or centrally using network management servers (NMS)
  • Wireless Client STA: This is typically the radio that is used in an 802.11 network which could be either in the AP or the client device. The radio has a unique MAC address.
  • Station Service: This includes of client stations and APs. The station features include: authentication, de-authentication, data confidentiality, MSDU delivery, Dynamic frequency selection (DFS), Transmit Power control (TPC), Higher layer time sync, QoS traffic scheduling, Radio measurement, Dynamic station enablement.
  • Distribution System Service: Operates only within APs and mesh portals.
