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 in one of the following modes:
An 802.11g Ad Hoc wireless LAN is a group of computers, each equipped with one Wireless Access Card or Adapter, that are connected as an independent wireless LAN. The wireless devices in a specific 802.11g Ad Hoc wireless LAN must be configured to share the same radio channel.
802.11g Ad Hoc wireless LAN configurations are appropriate for small departments or SOHO environments.
The 802.11g Wireless USB Adapter provides access to a wired LAN for 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 SSID is essential. All 802.11g Wireless USB Adapters that are in the wireless network must be configured with the same SSID that is used by the access point or wireless router.
The Infrastructure Wireless LAN configuration is appropriate for enterprise-scale wireless access to a central database or other central applications for mobile users.
