5OverviewWhat you can do with your Wireless LAN PC CardThe 5GHz Wireless LAN PC Card PCWA-C500 is a wireless network cardin a PC card format. You can use the Wireless LAN PC Card to construct awireless LAN environment for connecting multiple computers. With theWireless LAN PC Card, you can connect to another computer that has aWireless LAN PC Card (Peer to Peer Network connection mode), or youcan connect to a network through an optional wireless network accesspoint, the 5GHz Wireless LAN Access Point PCWA-A500 (Access PointNetwork connection mode).For details on connection modes, see the explanations on the followingpages.NoteYou can register and switch between various network settings, such as between AccessPoint Network and Peer to Peer Network connection modes.With Windows Me or Windows 2000:Peer to Peer Network connection modeAccess Point Network connection mode
6With Windows XP:Available networks
7Accessing the Internet from various places in the house(with Access Point Network connection mode)Access Point Network connection mode allows you to construct a wirelessnetwork based on an Access Point (optional). By using a computer with aWireless LAN PC Card, you can communicate with the Access Point, andshare files with other computers via the Access Point. Furthermore, if youconnect the Access Point to a DSL modem, cable modem or ISDN router,you can access the Internet from various places in the house.POWERMESSAGEWIRELESSNETWORK 1NETWORK 2NoteThe above illustration shows the Access Point connected to an Ethernet LAN, providingnetwork access to two wireless mobile notebook computers. Refer to the manualsprovided with the Access Point for details.
8High bit rate movie streaming playback*(with Peer to Peer Nework connection mode)Peer to Peer Network connection mode allows computers equipped withWireless LAN PC Cards to communicate directly, without using a WirelessLAN Access Point. With this connection mode, users can share filesdirectly from one computer to another.Because Peer to Peer Network connection mode is less prone to electronicinterference than Access Point Network connection mode making iteffective over a greater bandwidth, it is recommended that you use Peer toPeer mode when using high bit rate movie streaming applications.NotePoor radio conditions can cause interruptions of movie playback over wirelessconnections.* A system for simultaneously replaying transmitted files on the receiving computerwhile file transmission is still in progress.
