1Chapter 1IntroductionFarallon’s SkyLINE 11Mb Wireless PC Card provides networkconnectivity for laptop computers equipped with a PC Card (PCMCIA)slot. SkyLINE allows computers to join an IEEE 802.11 compliantDSSS wireless Local Area Network (LAN). A wireless LAN offers theadvantages of a wired LAN in situations where it is impractical to runconventional wiring.The SkyLINE 11Mb Wireless PC Card allows Macintosh PowerBookand Windows notebook users to build an Ad Hoc network or connectto an Infrastructure network. An Ad Hoc network connects two ormore computers directly to each other. An Infrastructure networkallows computers to tap into the resources of a wired network usinga wireless LAN access point. An access point (such as Apple’sAirPort Base Station) links wireless computers to an Ethernetnetwork.Farallon’s SkyLINE 11Mb Wireless PC Card uses a radio frequencymodulation technology called Direct Sequence Spread Spectrum(DSSS), which provides up to 11 Mbps bandwidth. The card’scompliance with the 802.11b standard ensures compatibility withmany popular wireless access points as well as interoperability withother DSSS 802.11 compatible wireless devices.In situations where more than one access point is used, a computerwith the SkyLINE card installed can roam from access point toaccess point, significantly increasing the range of the wireless LAN.TMa.Touch11book Page 1 Monday, April 17, 2000 5:38 PM
