Chapter 1 Product Overview
1.1 Introduction to the 802.11 b/g/n Mini Card
This GN-WS33N-RH 802.11b/g/n Wireless Local Area Network (WLAN) PCI-Express
Half Mini-card adapter is composed of the MAC, Baseband, and radio components,
PCI-Express half mini-card interface, and two RF connectors with high throughput
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-WS33N-RH overcomes environment multi-path effect by multi-input feature and to
keep its stable wireless performance and running wireless anywhere.
