  • wireless LAN (WLAN or Wireless Local Area Network)

    A wireless LAN is one in which a mobile user can connect to a local area network (LAN) through a wireless (radio) connection.

  • wireless router

    A wireless router is a device in a WLAN (wireless local area network) that determines the next network point to which a packet should be forwarded toward its destination. A wireless router works in the same way as the router in a hard-wired home or business LAN (local area network), but allows greater mobility for notebook or portable computers.
