A készülék csomagolása

WLAN PCI card TP-Link TL-WN551G 54Mbps is compliant with 802.11g and 802.11b standards. Using RF technology, the card enables wireless connection of a computer to local network.
Fontosabb jellemzők:
  • IEEE 802.11g Wireless PCI Adapter.
  • 54Mbps, full compliance to 802.11b
  • eXtended Range technology, expanding range up to 9 times in comparison to typical devices
  • Seamless Roaming allows for smooth switching between APs
The distinctive feature of the TL-WN551G card is implementation of "eXtended Range" technology developed by TP-LINK company. EXtended Range allows for 2 - 3 times (802.11b) or even 4 - 9 times (802.11g) longer range of operation in comparison with similar regular cards, ensuring full compatibility with these standards.
The card supports additional protocols ensuring security of transmitted data like 64/128/152-bit WEP, WPA/WPA2, IEEE802.1X, TKIP and AES. Together with firewall it can guarantee high protection level for the transmission and computer.
Due to SMA R/P socket the card can cooperate with any suitable external antenna, which will allow to employ the card even in difficult conditions.
The installation procedure is quite simple, the user gets software pack for managing the WLAN card.
