computing platforms equipped with communication applications such as wireless LAN. The small footprint connector can be implemented on
carrier board designs providing the ability to insert different removable PCI Express Mini Cards. Using this approach gives the flexibility to
mount an upgradable, standardized PCI Express Mini Card device to the carrier board without additional expenditure of a redesign. The PCI
