Network Configuration and Planning
The 802.11g Wireless USB Adapter supports legacy Ethernet LAN network
configuration options as defined by the IEEE 802 standards committee.
The 802.11g Wireless USB Adapter can be configured as one of the following:
z
802.11g AdHoc for departmental or Small Office and Home Office (SOHO)
LANs
z
Infrastructure for enterprise LANs
z
LAN Interconnection for point-to-point link as a campus backbone
NETWORK TOPOLOGY
An 802.11g AdHoc wireless LAN is a group of computers, each equipped with one
Wireless Access Card or Adapter, that is connected as an independent wireless
LAN. Computers in a specific 802.11g AdHoc wireless LAN must be configured to
share the same radio channel.
802.11g AdHoc wireless LAN configurations are appropriate for branch level
departments or SOHO operations.
The 802.11g Wireless USB Adapter provides access to a wired LAN for wireless
workstations. An integrated wireless and wired LAN is called an Infrastructure
configuration. A group of 802.11g Wireless USB Adapter users and a Wireless
Access Point compose a Basic Service Set (BSS). Each 802.11g Wireless USB
Adapter in a BSS can talk to any computer in the wired LAN infrastructure through
the Wireless Access Point.
An Infrastructure configuration extends the accessibility of a PC to a wired LAN and
doubles the effective wireless transmission range for two 802.11g Wireless USB
Adapters. Since the Wireless Access Point is able to forward data within its BSS, the
effective transmission range in an infrastructure LAN is doubled.
The use of a unique ID in a BSS is essential. Any PCs equipped with 802.11g
Wireless USB Adapters and configured without roaming options in an independent
BSS must be configured with a BSS ID that corresponds to the 802.11g Wireless
USB Adapter used in the BSS. Check your 802.11g Wireless USB Adapter for its
BSS ID or use the Access Point Configuration Utility program to determine the BSS
ID.
The Infrastructure Wireless Access LAN configuration is appropriate for enterprise-
scale wireless access to a central database or as a wireless application for mobile
users.
A point-to-point LAN configuration is possible when two Wireless Access Points are
linked with an optional directional antenna (the directional antenna is an optional
accessory; please contact your dealer for information). The optional directional
antenna makes LAN Interconnection to a wireless backbone between buildings
possible.
ROAMING
Infrastructure configuration also supports roaming capabilities for mobile users. More
