Chapter 1 Product Overview

1.1 Introduction to the AIRCRUISER N300 Mini Card

This GN-WS31N-RH 802.11b/g/n Wireless Local Area Network (WLAN) PCI-Express

Mini-card adapter is composed of the MAC, Baseband, and radio components,

PCI-Express mini-card interface, and two RF connectors with high throughput and

MISO (Multi-Input and Single-Output) feature. It operates at 2.4GHz frequency band,

providing fast (receive up to 150/300Mbps) and secure (WEP 64/128, WPA and WPA2)

connections to 802.11n networks from a single Adapter. It is backward compatible with

11b and 11g. GN-WS31N-RH overcomes environment multi-path effect by multi-input

feature and to keep its stable wireless performance and running wireless anywhere.
