TP-Link TL-WN851ND is a wireless PCI network card with a data transfer rate of up to 300 Mb/s. The device works in N standard and is ideal for HD video streaming, voice transmission or online games.
TP-LinkTL-WN851ND uses MIMO technology, which involves the use of several antennas for transmitting and receiving data, limiting signal losses caused by long distances or obstacles (steel or concrete walls of company or apartment buildings). Moreover, in contrast to 11g standard solutions, it is possible to create a long-distance connection with a wireless network.
Clear Channel Assessment (CCA) technology enables automatic avoidance of channel conflicts, increasing wireless transmission performance. Whereas WPA/WPA2 encryption protects WLAN from external threats.
