Sony PCWA-A200 User Manual

Getting started

You can build a Wireless LAN environment that connects up to 49 computers (a maximum 16 is recommended) by connecting the Wireless LAN Access Point PCWA-A100 (called the Access Point below) a computer in which the Wireless LAN PC Card PCWA-C100 is inserted. While enabling the sharing of files between all computers connected over the same Wireless LAN, it is also possible for multiple of computers within the same LAN system to connect to the Internet, if the Access Point is connected to a telephone line, an ISDN router, cable modem or to an xDSL modem. Furthermore, you can build a Wireless LAN environment between computers that are installed with the Wireless LAN PC Card without having to use the Access Point. (This is called peer-to-peer connection.)
