LevelOne MIMO Wireless PCMCIA Adapter, WPC-0500 user manual Introduction

1 Introduction

Thank you for purchasing the LevelOne MIMO Wireless LAN PC Card. With the MIMO technology, this card enables you to connect to wireless networks at farther distances than before. The card has two internal antennas for signal reception and one internal antenna for high power signal transmission. Not only the connection distance is enhanced, but also the “dead spots” in the network will be reduced. In addition, the card remains backward compatible to 802.11b and 802.11g. When the card is connecting to the standard 11g or 11b APs or Routers, it can perform much better than standard clients.

This card supports higher data throughput than the IEEE 802.11g standard. It supports specific ways to increase the data transfer rate at a time; compress the data and decrease the waiting time to send the next data to the Routers or APs. This feature is called Turbo Mode. When the card is connecting to the Routers or APs with the proprietary feature, the wireless network will be more effective.

For WLAN security issues, this card supports 64/128-bit WEP data encryption that protects your wireless network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that combines IEEE 802.1x and PSK (Pre-Shared Key), TKIP (Temporal Key Integrity Protocol) technologies. Client users are required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is encrypted/decrypted by a dynamically changed secret key. Furthermore, this card supports WPA2 function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption Standard), which is a requirement for some corporate and government users.

When you use the devices such as Voice over Internet Protocol (VoIP) phones, televisions, VCRs and MP3 players, how can you speed up the audio, video and voice data to pass through the wireless network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a profile of the IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data traffics by the data categories to provide enhanced multimedia support. This card supports the advanced technology for sure.

This card is cost-effective, together with the versatile features; it is the best solution for you to build your wireless network.
