Product Description: This Wireless N USB adapter complies with the IEEE 802.11n (Draft 2.0), IEEE 802.11g the IEEE802.11b standard. Wireless transmission rates of up to 150Mbps. The adapter uses 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. The product supports 64/128 bit WEP encryption, as well as WPA/WPA2, TKIP, AES encryption and mechanisms in addition to the adapter's QSS (Quick Secure Setup) feature, allowing users to quickly and easily set up wireless security. This product can also simultaneously run bandwidth-intensive applications such as voice and video. Application uses a lot of bandwidth is sensitive to disruption, such as voice and video applications priority to ensure quality. It can also work well with other 11g and 11n protocol wireless products. Product Features: 2.1 provides two methods of operation: Infrastructure and special. 2.2 use of MIMO technology in the wireless rates up 300 mbps. 2.3 CCA technology automatically avoiding channel conflicts using its channel selection feature Quick Secure Setup 2.4, in line with WPS worry free wireless security 2.5 supports 64/128 WEP, WPA standards compliance 128 (TKIP / AES), Shared Key Authentication, IEEE 802.1 x. 2.6 Simple configuration and monitoring. 2.7 support roaming technology to ensure efficient wireless connections. 2.8 supports Windows 2000 / XP or Vista operating system Specification: Software Specification Standards IEEE 802.11n (draft 2.0), IEEE 802.11g, IEEE 802.11b, CSMA / CA with ACK Wireless Signal Rate and Auto Retreat 11n: 270/243/216 / 162/108/81/54/27Mbps??????? 135/121.5/108/81/54/40.5/27/13.5Mbps??????? 130/117/104/78/52 / 39/26/13Mbps?????? 65/58.5/52/39/26/19.5/13/6.5Mbps 11g: 54/48/36/24/18/12/9/6M (adaptive) 11b: 11/5.5/2/1M (adaptive) Frequency Range 2.4-2.4835GHz Wireless Transmit Power 20dBm (MAX) Modulation Type OFDM/CCK/16-QAM/64-QAM Receiver Sensitivity 270M:-68dBm @ 10% PER 130M: - 68dBm @ 10% PER 108M:-68dBm @ 10% PER 54M:-68dBm @ 10% PER 11M:-85dBm @ 8% PER 6M:-88dBm @ 10% PER 1M:-90dBm @ 8% PER encryption security 64/128 / 152 bit WEP, WPA/WPA2, WPA-PSK/WPA2-PSK (TKIP / AES) Support System Version Windows 2000/XP/Vista Hardware Specification Interface USB 2.0 Hi-Speed ??Antenna Type Internal Omni-directional Antennas Certification CE, FCC work Temperature 0 ° C ~ 40 ° C (32 ℉ ~ 104 ℉) Storage Temperature -40 ° C ~ 70 ° C (-40 ℉ ~ 158 ℉) Relative humidity 10% ~ 90%, non condensation Storage Humidity 5% to 95% non-condensing Dimensions 4CM x 1.5CM x 0.35CM
