WMG2503

Wireless 802.11b/g PCIe Mini Card

Description

The WMG2503 is the new PCI Express Mini Card interface supporting both

IEEE 802.11b/g in a form factor half the size of a Mini PCI card. The

WMG2503 provides cost effectiveness, low power consumption, and low

heat dissipation. For easy integration into the host device, the WMG2503 in

full compliance with the PCI Express Mini Card specification supports USB

2.0 signaling over the Mini Card interface. Despite its small size, the

WMG2503 delivers full IEEE 802.11b /g standards, as well as the

advanced security and quality-of-service (QoS) features of 802.11i, 802.1x,

and 802.11e.. It provides plug-and-play wireless connectivity in the

2.4-GHz band anywhere in the world.
