Key Features
 Plug & Play —
o No driver on the host device is required for radio operation
o Radio operation is independent of the operating system on computer or any connecting device
(Windows 98/2000/ME/XP, MAC, Linux, Unix, embedded, etc.), as long as the device has a
properly supported Ethernet port.
 Industry standard IEEE 802.11g-compliant wireless interface; Interoperable with AP and Client
radios from other vendors
 The IP Bridging Mode, when enabled, allows the sharing of the Station Radio by multiple computers
 Ethernet (802.3 compliant) host interface to enable true Plug & Play
 Maximum 54 Mbps data rate and automatic selection of lower data rates in degraded RF
environment
 Integrated omni-directional-antenna to provide best tradeoff between link-quality and mobility
 Remote network management achievable through Web browser-based configuration tool run from
any OS platforms
 Remote firmware/software upgrade can be achievable from any OS platforms. The
firmware/software upgrade do not affect the operating frequencies of devices sold in the US.
