Ad-hoc Wireless LAN Topology - Continued
The ParkerVision miniPCI1500 Wireless PC 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.
