Understanding Wireless LAN Technologies
Before delving into the specifics of the driver, it’s crucial to understand the underlying wireless technologies it supports. The IEEE 802.11 family of standards defines the specifications for Wireless Local Area Networks (WLANs). The RTL8191SU chipset specifically supports:
-
802.11b: This is one of the earliest WLAN standards, offering a maximum data transfer rate of 11 Mbps. While still functional, it is generally considered outdated and slower compared to newer standards.
-
802.11g: This standard offers a significant improvement over 802.11b, providing data transfer rates up to 54 Mbps. It operates on the 2.4 GHz frequency band and is backward compatible with 802.11b.
-
802.11n: This standard introduces Multiple-Input Multiple-Output (MIMO) technology, enabling significantly higher data transfer rates, potentially reaching up to 300 Mbps (depending on the configuration and number of antennas). It can operate on both the 2.4 GHz and 5 GHz frequency bands.
The Realtek Wireless LAN ICs IEEE 802.11b/g/n RTL8191SU Driver 1086.48 is designed to ensure that the RTL8191SU adapter can properly utilize these technologies to establish and maintain a wireless network connection.
