PCI Wireless N adapter (300 Mbps.) Compatible with 802.11n, 802.11b and 802.11g Advanced Encryption MIMO Evo-W300PCI technology uses the most advanced wireless, Wireless-N network technology. By using signal reflection technology, Wireles N( Multiple inputs, multiple outputs), the coverage of the wireless network is considerably increased and the dead points are reduced. Unlike the ordinary 802.11b/g wireless networks, MIMO can increase up to four times the transmission range. On the other hand, when the 802.11n devices are on both connecting ends, MIMO technology increases up to three times the original 802.11g standard transmission speed.
