WFS001 User’s Manual Introduction
Overview
WFS001 PCI Module is designed to provide wireless communication for all wireless device based systems. It
communicates via the standard 802.11b/g protocols but with transmission frequency shifted to 900MHz
(902‐928MHz). TheWFS001uses the AR5414 wireless chipsetfromAtheros.This module isconnected tothe
PCI bus through a PCI
 connector and special circuitry to allow for compatibility with either 3.3V or 5V PCI
signaling..
