The WL-RT8188 Draft N Wireless USB Adapter complies with IEEE 802.11n (Draft 2.0), IEEE 802.11g, and IEEE 802.11b standards. Wireless transmission rates can reach up to 150Mbps. The adapter employs MIMO technology and has two internal Intelligent Antennas providing even better wireless performance, transmission rates, stability and CCA technology automatically avoids channel coverage. At the same time, conflicts using its channel selection feature. This product supports 64/128/152-bit WEP encryptions, as well as WPA/WPA2 and WPA-PSK/WPA2-PSK encryptions and mechanisms in addition to the adapters QSS (Quick Secure Setup) feature, allowing users to quickly and easily setup wireless security. It also works well with other 11g and 11n protocol wireless products. Product features Provides USB 2.0 connector. Complies with IEEE 802.11n(draft 2.0), IEEE 802.11g, and IEEE 802.11b standards.
