(Wireless Lan Card)
1.0 Scope
1.1 Document
This document is to specify the product requirements for 802.11 g/b Wireless Lan
Card. This Card is based on Ralink chipset that complied with IEEE 802.11g and
IEEE 802.11b standard from 2.4~2.5GHz, and it can be used to provide up to 54Mbps
for IEEE 802.11g, or 11Mbps for IEEE 802.11b to connect your wireless LAN.
With seamless roaming, fully interoperability and advanced security with WEP
standard, 802.11 g/b Wireless Lan Card offers absolute interoperability with
different vendors’ 802.11g and 802.11b Access Points through the wireless LAN.
