Abocom WMG2400 User Manual

802.11b/g Wireless miniPCI Card

The WMG2400 is a mini PCI card that connects
your notebook to a wireless local area notebook.
Incorporating the IEEE802.11g standard’s
mandatory modulation schemes, the WMG2400 is
backwards compatible with all the existing 802.11b
products already out there. Moreover, the high­speed transfer rate of up to 54Mbps makes it an
essence for today’s high-bandwidth demand.

The WMG2400 is a very small card that can fit into
any notebook, handheld or desktop computer
equipped with a Mini PCI (Type III B slot) interface
for wireless network applications. It allows you to
take full advantage of your notebook’s mobility with
access to real-time information and online services anytime and anywhere. It slides easily into the
MINI PCI expansion slot to enable a wireless connection to your network.
