Computers equipped with a wireless adapter can communicate with each
other as an independent wireless LAN by configuring each computer to
the same radio channel. However, the Wireless Barricade can provide
access to your wired/wireless LAN or to the Internet for all wireless
workstations. Each wireless PC in this network infrastructure can talk to
any computer in the wireless group via a radio link, or access other
computers or network resources in the wired LAN infrastructure or over
the Internet via the Wireless Barricade.
The wireless infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also doubles the effective wireless
transmission range for wireless PCs by retransmitting incoming radio
signals through the Wireless Barricade.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure:
