This adapter supports the 802.11a, 802.11b, and 802.11g wireless standards. This means it can operate on both the 2.4 GHz band (for 802.11b/g) and the 5 GHz band (for 802.11a). The maximum data transfer rate for this card is 54 Mbit/s, which is typical for 802.11g and 802.11a standards. It is suitable for general internet browsing, email, and standard office applications. Security is provided through support for WPA (Wi-Fi Protected Access) and WPA2 encryption protocols, ensuring that wireless communications are protected from unauthorized access. The dual-band capability offers flexibility in connecting to different wireless networks, allowing users to choose the band that offers the best performance or availability. This card was a common component in business laptops requiring reliable wireless networking.
