WLAN1500 Wireless PC LAN Card

Ad-hoc Wireless LAN Topology - Continued

The ParkerVision Wireless LAN Card provides access to a wired LAN for wireless computers. An integrated wireless and wired LAN is called an Infrastructure confi guration. A group of wireless LAN computer users and an Access Point constitute a Basic Service Set (BSS). Each wireless-equipped computer in this BSS can talk to any computer in the wired LAN infrastructure via the Access Point.

Infrastructure confi guration will extend the accessibility of a wireless station to the wired LAN. Multiple Access Points will allow roaming and it will increase the transmission range. The Access Point is also able to forward data within its BSS. The effective transmission range in an Infrastructure LAN is doubled.
