ZyAIR 200 Wireless LAN USB Adapter
An Ad-hoc wireless LAN is a group of computers, each equipped with one wireless adapter, and connected
as an independent wireless LAN. Computers in a specific Ad-hoc wireless LAN must be configured on the
same radio channel. An Ad-hoc wireless LAN is available at a departmental scale for a branch or SOHO
operation.
Wireless LAN Topology Infrastructure
Diagram 2 Wireless LAN Infrastructure Example
The ZyAIR 200 provides access to a wired LAN for wireless computers. An integrated wireless and wired
LAN is called an Infrastructure configuration. 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 configuration 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.
