Abocom WM2504 User Manual

802.11b/g Wireless Mini PCI Card

The WM2504 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 WM2504 is backwards
compatible with all the existing 802.11b products
already out there. Moreover, the high-speed transfer
rate of up to 54Mbps makes it an essence for today's
high-bandwidth demand.

The WM2504 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.
