- 300Mbps Wireless transmission rate-MIMO technology with stronger signal penetration strength wider wireless coverage providing better performance and stability-CCA technology automatically avoids channel conflicts using its channel selection feature-Compatible with 11g and 11b equipment Intel Centrino Compatibility testedThe TL-WN821N Wireless N USB Adapter complies with IEEE 802.11n IEEE 802.11g and IEEE 802.11b standards. Wireless transmission rates can reach up to 300Mbps. The adapter employs MIMO technology and has internal Intelligent Antennas providing even better wireless performance transmission rates stability and coverage. At the same time CCA technology automatically avoids channel conflicts using its channel selection feature. This product supports 64/128-bit WEP encryptions as well as WPA/WPA2 and WPA-PSK/WPA2-PSK encryptions and mechanisms in addition to the adapter’s QSS (Quick Secure Setup) feature allowing users to quickly and easily setup wireless security. This product can also simultaneously operate bandwidth intensive applications such as voice and video. Applications using a lot of bandwidth that are sensitive to interruptions such as voice and video applications are given priority in order to assure quality. It also works well with other 11g and 11n protocol wireless products.- Provides two methods of operation: Infrastructure and Ad-Hoc- Adopts MIMO technology for wireless rates of up to 300Mbps- Adopts CCA technology which automatically avoids channel conflicts using its channel selection feature- Quick Secure Setup complies with WPS for worry free wireless security- Supports 64/128-bit WEP complies with 128 bit WPA standard(TKIP/AES) supports MIC IV Expansion Shared Key Authentication IEEE 802.1X- Simple Configuration and monitoring- Supports Roaming technology guaranteeing efficient wireless connections.- Supports Windows 2000/XP/Vista/7SpecificationStandards: IEEE 802.11n IEEE 802.11g IEEE 802.11b CSMA/CA with ACKWireless Signal Rates With Automatic Fallback- 11n: Up to 300Mbps(dynamic)- 11g: Up to 54Mbps(dynamic)- 11b: Up to 11Mbps(dynamic)Frequency Range: 2.4-2.4835GHzWireless Transmit Power: 20dBm (max.
