Description
The Realtek RTL8191SN is a highly integrated MIMO (Multiple In, Multiple Out) Wireless LAN (WLAN) solution that complies with the IEEE 802.11n Draft specification 2.0. It combines a MAC and 2T2R capable baseband in a single chip. When used with Realtek's RF IC's (RTL8256 at 2.4GHz), the RTL8191SN provides a complete solution for a high-performance wireless client.
