Introduction
The WM821-M-LS is a dual-band, quad-mode wireless network adapter that works on all the frequen-
cies allocated for WLAN operation everywhere in the world. It is in compliance with the Draft
IEEE802.11n standard in a 2x3 MIMO configuration. It also complies with the IEEE 802.11a, 802.11g,
and 802.11b standards. WM821-M-LS features the compactness and high bus speed of the Mini PCI
specifications which gives users of laptops, notebooks, tablet PCs, and other mobile computing devices
transparent Internet access anywhere in the world through any Wi Fi network without software changes
or additional hardware.
Able to provide greater than 100Mbps real world throughput using high-speed spatial multiplexing
modes, the WM821-M-LS provides the freedom to work as you wish, wherever you wish, using what-
ever kind of application you wish to use. The adapter installs directly in any host device with a Mini PCI
slot: just plug it in and you’re ready to access local resources and/or the Internet at the highest speed
the WLAN, the location, and the host computer can provide. It is ready to work “out of the box” in any
embedded device or in any computer running Microsoft® Windows 2000, or XP. The WM821-M-LS
Mini PCI Card is truly a “must-have” for every productivity-sensitive laptop, notebook, or tablet PC user
and any bandwidth-sensitive embedded design..

Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired
systems. WLANs are flexible and easy to setup and manage. They are also more economical than
wired LAN systems.
