Abocom Wireless 802.11b/g PCIe Mini Card WMG2503 Specifications

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.
